I had a discussion with someone about needing better braking when going with more power. This is what I said to them at the time and I'm sure they won't mind me reusing it here: 
 
Regarding whether you need better brakes with FI or not, the point I make is always the same. Will having the extra power mean that you will drive faster everywhere? Of course on the circuit you will be going faster before you start braking so better brakes is always a good choice, but on the road if you are doing normal driving around town or on the motorway I would guess that your speed will be about the same, you will just get there sooner with the extra power. This means that under those situations you probably won't need any extra braking.
 
If you are looking to blast on the back roads and through some corners then again you have to think "Am I going to go faster into the corner or just accelerate harder but stick to a certain speed?" if you are planning on reaching higher speeds then of course the extra braking will help but if you don't intend on reaching higher top speeds then maybe it won't be as effective.
 
I guess you know how you drive and how much you use the brakes so you can always base your decision on that.

Here is the makeup of the supercharger unit itself: 
 

 
For anyone interested here is a photo of the Supercharger unit and the Drag reduction system that we spoke about earlier... 
 

 
You can see the 3rd roller wheel has a spring which when no load is on retracts to reduce load.
 
 
Also here is a Dyno run of the 3 systems in place. Stock, Step1 (39mm Restrictor) and Step 2 (43mm Restrictor)
 

 
I'm currently on Step1 39mm Restrictor. As you can see it doesn't affect to much low down. But actually starts to pull the hp down at about 4800rpm. 
 
My plan is to run the car in this setup for a little while, then upgrade to the 43mm restrictor. But i'm more than happy on the 39mm restrictor and the power feels good! Estimated at about 275hp currently based on the amount of Air we measured through the air box whilst mapping.

somebody mentioned something about impeller speeds...

The GTS7040 size unit as used in the kits for 86 has a maximum recommended impeller speed of 110,000. Many have gone a little bit faster and been OK (in fact the 86 in stock configuration does go over by a small amount) but for warranty purposes, you don't really want to push these boundaries.
 
The crank pulley diameter is 148mm on these cars and the stock pulley size on the V2 is 90mm. The drive ratio of the supercharger unit is 9.444 and so at 7500 rpm the impeller is actually rotating at  almost 117,000rpm. Certainly couldn't recommend that you try and go any faster than that but I do know of some shops who have pushed the boundaries and gone for an 85mm pulley and are spinning it up at over 123K. So far they haven't broken it but it's only getting limited use on circuit and they accept that any breakage (if it should occur) would't be covered by any warranty etc.

Here is a car in Japan that's got the same supercharger unit but with the HKS Stroker kit, HKS Cams and no restrictor on the intake...
 
365ps / 360bhp at the Hubs. Probably around 400bhp at the flywheel.

Yeah i've wanted the shorter plate with the 3D Gel Letters as this will match the TRD Gloss black really well. but not sure on the legality of it. hence why i've not done it yet.  Benefit of the TRD kit is the bracket is made for a smaller plate. 
 
 
 
Do it! You won't be disappointed! One of the best mods i've done! With a few tweaks it really is an awesome car! 
 
You've already got the KWs! So you won't need much more! A good brake pad, and I assume you're already decat! It's asking to be bolted on! 

Took it out on it's first 'proper spirited drive' yesterday.
 
We met up with the Piston-heads forum group at Thetford and then convoyed to Stowmarket along some awesome back roads. We then drove a coastal road to Aldeburgh for some fish and chips! Around 70 cars turned up for the day!
 
All the way it was an absolute blast! On the B-Roads with momentum it just flys! It was catching me out at just how quick it accelerates out of corners! I'm glad I've got good brakes and a good pad compound! 
 
I was behind an Audi RS4, BMW M3, EVO 8 and an RX7. Keeping up was no problem. Corners, straight lines and the likes were just perfect! This charger really makes for an awesome 'spirited driving' car! Staying in the 4 - 7k range on a back road is so much fun. A gear higher usually in corners makes it easier and a bit more usable out of corners. Fully controllable on the throttle, surge of power when you get on the throttle between corners and then plenty of torque out of corners to not need to shift down to 2nd. At one point I had an M3 behind me and wasn't holding him up at all. 
 
Usually would have been a massive problem up front with those sort of cars! 
 
All day I was getting compliments on how well it drove and how awesome it sounds! Few guys behind actually pulled over and complimented how great it sounded. On lift off there's a really nice burble and the odd pop apparently. One guy behind me has got some video which he's sorting out and will send to me. 
 
Lifting off at around 7.5k rpm and you get the awesome recirc sound. Like your traditional Blow Off sound but a little more subtle and longer, and it's not super chavy which is nice, from the outside you can just hear that something is going on and the sound of Darth Vader breathing. 
 
Out of roundabouts and B-Roads the Power to Weight is now identical to an E46 BMW M3. On the B-Roads I didn't really find anything out of league. 
 
If you love reving your car out and using all the power of the rev range then the HKS Centrifugal is definitely worth thinking about! It still gives the sense of having to work the car and wind it up. But you just have a hell of a lot more power all of the time. It just keeps reving and reving! No way to really explain it unless you drive it. But imagine the stock car with just more power everywhere! 
 
One of the best things I've done to the car! 
 
Fuel wise, yesterdays run, driving it very hard 95% of the time. Full throttle blasts between most corners. I averaged 27mpg. Nothing to bad! Average I'm now getting 33mpg. Which is 2 mpg down on what I used to get. Not really a noticeable difference! And since i've had the charger fitted i've not really been economical with it! I should think I can get it up to around 35mpg again with a lighter right foot.

For a track biased car I feel the HKS V2 maybe the way forward tbh.

Jay summed it up pretty well , Sprintex has more initial torque being a positive displacement charger, where as the HKS makes more top end power.
 
the HKS keeps the spirit of the Stock NA car thou more revs more power where as the Sprintex makes it like a big V8...
 
I have seen something else that looks good thou
 

It's essentially just a profile for sharing photos. It's good because you can chose who and what you want to come up on your feed! I only follow car related people on mine, and car related people only follow me! 
 
So it's not knowing any photos you post car related are going to be enjoyed and not just piss people off with filling up their timeline of crap they're not interested in. Like wise my feed is only full of cars and stuff i'm interested in. 
 
I find Facebook and Twitter is full of too much crap and junk between useful and interesting posts! 
 
Its a good place to get a little community of people and a following for a specific topic. I always tend to get the same few people comment / like my photos from around the world.

You can see that Julia is happy with the noise levels (outside anyway!)   And then a remap - not shiny, but beautiful in a different way!!   Very happy chap (me) left Fensport, that's for sure!!     Happy to share the experience with anyone interested!!

Personally I have - @GT86Jay

My plan is to run the car in this setup for a little while, then upgrade to the 43mm restrictor. But i'm more than happy on the 39mm restrictor and the power feels good! Estimated at about 275hp currently based on the amount of Air we measured through the air box whilst mapping.

You may want to bear in mind that you should never 'slam the throttle' at such low rpm. Never do this to an engine. Feed it in until you are at least over 3500rpm before going wide open throttle. 

I’ve started this thread which will probably be like a small Mods blog as i’ve never really set one up for my car.
 
 
I’ve always thought about boosting my GT86 but never really decided on a route or if it would be viable. But after driving Maz’s car a fair bit on the road and once on track it made sense to go the Centrifugal Supercharged route.
 
For the style of driving and type of roads I drive it made sense. The HKS supercharger to me just feels like a bigger block NA car. You don’t get that sudden rush of power in one peak. It just keeps climbing and climbing. Over 6.5krpm is just awesome!
 
Being hands on and quite technical and capable I decided i’d fit the kit myself as a sense of achievement and a little personal project with the help from Maz at HKS Europe. We picked this weekend as it gives me the extra bank holiday day and fitted in best with Adrian mapping it at Fensport this week.
 
We started the install at about 5:30 Friday evening with the plan to get all the prep work and  old bits off the car so that Saturday morning we could start fitting the go-faster bits.
 
The Manual is relatively easy to understand although at times the Japanese to English translation is a little poor. But luckily with having Maz to help he could read the Japanese ones and it all made sense!
 
First thing is to get the Bumper off and expose the front of the car. Along with unbolting the crash bar as we fit some brackets to this for the Intercooler.
 

 
We also remove the bonnet catch and top bonnet support for later.
 
Also free’d up the Oil cooler and made sure this was out the way temporarily whilst fitting the new parts.
 
What’s impressive with the HKS kit is the amount of dedication and precision gone into planning the kits. We spent a fair couple of hours adding clips to existing hoses and supporting stock parts for the preparation of them receiving positive boost. Parts like the canister can under the manifold. Usually the hoses are just pushed on loosely. But now they’ll see positive pressure HKS actually supply clips to add to these hoses to make sure they don’t pop off! It would be a real PITA if one popped after install! It just gives a little bit of piece of mind that you’re adding reliability.
 
Interestingly Version 1 of the supercharger didn’t have these extras! But they added them for Version 2.
 
Once this was all done and the fiddly bits out of the way we had the car ready to receive boost! We have to add a bracket to the underside of the Crash beam which will be used to support the intercooler so we got this added and in place. This is fiddly as you’ve got to get a nut on the bolt which is half way along from an opening at the end! We got there in the end!
 

 
Also had to cut a little channel in the upper bonnet support for the charge pipe to come back into the engine bay.
 

 
Next up was fitting the actual compressor to the car. The bracket is very substantial and quality is outstanding. Everything just fitting into place lined up and went perfectly. The bracket basically fits into the existing holes in the Alternator and fits in really well. After a few bolts, belt on and tensioner released we had the unit in place!
 

 
We then went ahead and mounted the intercooler in place. It looks as though it sits on the bottom shelf. But it actually hanging from 2 bracket. Its a very good fit and the HKS kit hasn’t failed to impress regarding quality and fitment!
 

 
This charger uses a traction fluid system with it’s own oil cooler to lubricate the charger components. A tank is mounted just beside the airbox, using two existing holes in the support just below the bonnet release. After cutting the supplied hoses to length, adding an inline filter and clipping it all on. The traction fluid system was in place along with the cooler, bottle, lines and filter. It's important to get the traction fluid cool and ensure everything is working correctly. As this can seriously damage the compressor if the fluid isn't there as expected!
 

 

 
Now to put the stock airbox back into it’s location ready for the intake suction pipe.
Any airbox or induction that uses the stock intake pipe location should fit with this kit.
 
Here we put a restrictor plate between the supercharger and the intake air box. The restrictor is a simple plate which sandwiches between the intake pipe and the charger with two gaskets. It restricts the power from the capable 400hp to about 300hp to use on a stock engine block! The restrictor is great as it keeps all the available torque and power low and and just clips the peak power towards the top end. You can of course run it without a restrictor if you dare on a stock engine!
The great thing with this unit is if you do decide to go for a forged engine you can simply remove the restrictor, tweak the map and you’ll be able to produce around 400hp comfortably with the same kit.
 

 
We then plumbed in the intercooler which is a fiddly job as there isn’t much room, especially if you have the oil cooler installed too! This kit was obviously designed, tested and fitted in Japan where they do not have HID headlights also meaning they haven't got the headlight washers! Which actually get in the way a fair bit on the UK cars as the headlight washers sit just where the pipe wants to naturally sit. But after some persuasion and careful positioning it does all go back in and the headlight washer still works.
 

 

 
Moving on by connecting up the throttle body intake pipe from the intercooler. This bit was straight forward. The pipe sits in the neat hole that was cut earlier on in the process. All connecting up and on the throttle body. We have a completed plumbed in Supercharger.
 

 

 
We have to take a vacuum line from the vacuum brake line so that the Recirc valve can work. For this we simply take a T-Piece in the original vacuum line and connect it to the valve.
 

 
At this point the install is done! We topped up the traction fluid tank. Fired it up and ensured there are no air leaks and fluid is circulating ok.
 
Starts first time and the sound is just fantastic. A real rushing of air and breathing sound!
 
One with the final bits like the bumper, and side indicators etc. And it’s finished!
 

 

 
All together it took us around 12 hours with two of us working on it. What helped was Maz’s ability to know stuff as he’d already done it on his car. Little tips and tricks to make things easier and the knowledge of knowing what we we’re un-doing was correct! The manual makes it easy as the install is split up into smaller chunks of work. So you’re only ever aiming for one goal at a time. Such as ‘Fit the intercooler’ - ‘For this you will need’. Rather than tackling the entire project with all the bits in one go.
 
Off to Fensport today for the map! Once i've driven it with some boost i'll report back
 

The car is absolutely fantastic! Great fun and keeps the characteristics of the NA form car! High revs are just mental! 
 
Mapping all went great. Adrian done a fantastic job with the base map and didn't require too much tweaking.
 
Drive home was great fun. The boost just builds and builds. Quicker than I need! 
 
 
 
It basically put it up £380 for the entire year over NA form. Not to bad considering i'm 21. 

I’ve started this thread which will probably be like a small Mods blog as i’ve never really set one up for my car.
 
 
I’ve always thought about boosting my GT86 but never really decided on a route or if it would be viable. But after driving Maz’s car a fair bit on the road and once on track it made sense to go the Centrifugal Supercharged route.
 
For the style of driving and type of roads I drive it made sense. The HKS supercharger to me just feels like a bigger block NA car. You don’t get that sudden rush of power in one peak. It just keeps climbing and climbing. Over 6.5krpm is just awesome!
 
Being hands on and quite technical and capable I decided i’d fit the kit myself as a sense of achievement and a little personal project with the help from Maz at HKS Europe. We picked this weekend as it gives me the extra bank holiday day and fitted in best with Adrian mapping it at Fensport this week.
 
We started the install at about 5:30 Friday evening with the plan to get all the prep work and  old bits off the car so that Saturday morning we could start fitting the go-faster bits.
 
The Manual is relatively easy to understand although at times the Japanese to English translation is a little poor. But luckily with having Maz to help he could read the Japanese ones and it all made sense!
 
First thing is to get the Bumper off and expose the front of the car. Along with unbolting the crash bar as we fit some brackets to this for the Intercooler.
 

 
We also remove the bonnet catch and top bonnet support for later.
 
Also free’d up the Oil cooler and made sure this was out the way temporarily whilst fitting the new parts.
 
What’s impressive with the HKS kit is the amount of dedication and precision gone into planning the kits. We spent a fair couple of hours adding clips to existing hoses and supporting stock parts for the preparation of them receiving positive boost. Parts like the canister can under the manifold. Usually the hoses are just pushed on loosely. But now they’ll see positive pressure HKS actually supply clips to add to these hoses to make sure they don’t pop off! It would be a real PITA if one popped after install! It just gives a little bit of piece of mind that you’re adding reliability.
 
Interestingly Version 1 of the supercharger didn’t have these extras! But they added them for Version 2.
 
Once this was all done and the fiddly bits out of the way we had the car ready to receive boost! We have to add a bracket to the underside of the Crash beam which will be used to support the intercooler so we got this added and in place. This is fiddly as you’ve got to get a nut on the bolt which is half way along from an opening at the end! We got there in the end!
 

 
Also had to cut a little channel in the upper bonnet support for the charge pipe to come back into the engine bay.
 

 
Next up was fitting the actual compressor to the car. The bracket is very substantial and quality is outstanding. Everything just fitting into place lined up and went perfectly. The bracket basically fits into the existing holes in the Alternator and fits in really well. After a few bolts, belt on and tensioner released we had the unit in place!
 

 
We then went ahead and mounted the intercooler in place. It looks as though it sits on the bottom shelf. But it actually hanging from 2 bracket. Its a very good fit and the HKS kit hasn’t failed to impress regarding quality and fitment!
 

 
This charger uses a traction fluid system with it’s own oil cooler to lubricate the charger components. A tank is mounted just beside the airbox, using two existing holes in the support just below the bonnet release. After cutting the supplied hoses to length, adding an inline filter and clipping it all on. The traction fluid system was in place along with the cooler, bottle, lines and filter. It's important to get the traction fluid cool and ensure everything is working correctly. As this can seriously damage the compressor if the fluid isn't there as expected!
 

 

 
Now to put the stock airbox back into it’s location ready for the intake suction pipe.
Any airbox or induction that uses the stock intake pipe location should fit with this kit.
 
Here we put a restrictor plate between the supercharger and the intake air box. The restrictor is a simple plate which sandwiches between the intake pipe and the charger with two gaskets. It restricts the power from the capable 400hp to about 300hp to use on a stock engine block! The restrictor is great as it keeps all the available torque and power low and and just clips the peak power towards the top end. You can of course run it without a restrictor if you dare on a stock engine!
The great thing with this unit is if you do decide to go for a forged engine you can simply remove the restrictor, tweak the map and you’ll be able to produce around 400hp comfortably with the same kit.
 

 
We then plumbed in the intercooler which is a fiddly job as there isn’t much room, especially if you have the oil cooler installed too! This kit was obviously designed, tested and fitted in Japan where they do not have HID headlights also meaning they haven't got the headlight washers! Which actually get in the way a fair bit on the UK cars as the headlight washers sit just where the pipe wants to naturally sit. But after some persuasion and careful positioning it does all go back in and the headlight washer still works.
 

 

 
Moving on by connecting up the throttle body intake pipe from the intercooler. This bit was straight forward. The pipe sits in the neat hole that was cut earlier on in the process. All connecting up and on the throttle body. We have a completed plumbed in Supercharger.
 

 

 
We have to take a vacuum line from the vacuum brake line so that the Recirc valve can work. For this we simply take a T-Piece in the original vacuum line and connect it to the valve.
 

 
At this point the install is done! We topped up the traction fluid tank. Fired it up and ensured there are no air leaks and fluid is circulating ok.
 
Starts first time and the sound is just fantastic. A real rushing of air and breathing sound!
 
One with the final bits like the bumper, and side indicators etc. And it’s finished!
 

 

 
All together it took us around 12 hours with two of us working on it. What helped was Maz’s ability to know stuff as he’d already done it on his car. Little tips and tricks to make things easier and the knowledge of knowing what we we’re un-doing was correct! The manual makes it easy as the install is split up into smaller chunks of work. So you’re only ever aiming for one goal at a time. Such as ‘Fit the intercooler’ - ‘For this you will need’. Rather than tackling the entire project with all the bits in one go.
 
Off to Fensport today for the map! Once i've driven it with some boost i'll report back

Off to Fensport today for the map! Once i've driven it with some boost i'll report back
 

Pretty much what Lee said. 
 
I didn't need anything other than what was supplied. 
 
Only one mistake we've noticed is that we kept the Outside air temp in stock location and it now reads about 30c all times as it's behind the intercooler hot air! So worth taking note with that! 
 
Quick bumper off and move it will sort that. 
 
You don't need to bleed the traction fluid system. The charger comes pre-filled with fluid. So you just connect up. Fire it up for a few seconds, ensure fluid is flowing and you're good. 
 
I wouldn't want to do it without a ramp personally. But you don't need it off the ground. Once the bumper is off that's pretty much it. 
 
Now at Fensport! Mapping commencing shortly.
