Tuning a NA

Recommended Posts

I have owned my car for near 18 months,

soon after she arrived a 2.5" over pipe and 2.5" resonated cat delete pipe were fitted,

mated to a standard back end.

 

A K&N filter sits in the standard air box.

 

Last year at the Tuning Developments meet she made circa 200 flywheel bhp,

which was not too shabby?

 

Now bought a HKS system to mate to 2.5" pipework,

waiting until next month to fit, when I will ECUtek, with a view to reducing start up retard

and in doing so, hoping not to annoy neighbours!

 

Casual observation being HKS pipework diameter is not much bigger than 2nd cat pipe.

 

Motivation for pipework change being she sounds just a bit too homogenised for a sports car,

drove a new Cayman S a couple of months ago and that certainly made its presence felt and indeed heard!

Many cars from the MGB GT to present day have exhausts tuned for a feeling of noise and performance,

I might add that for me,it is not the noisier the better situation!

 

I have a certain amount of nervous trepidation in doing so, not wanting to fook things up,

hoping that HKS as a top brand have spent a bob or two on R&D?

I have used HKS on my Celica gt4 to good effect.

 

Figures suggest I will be making circa 220 flywheel bhp with the above mods,

which I hope to be happy with!

An increase in torque would to much appreciated.

 

Driving on reasonably unpopulated rural roads,

I achieve 35.9 mpg average,

this for me provides affordable fun.

 

The car reminds me of a previous favourite,

Opel Kadette 2.0GTE,

this one had a plated (clutch type) LSD which allowed me to get the back end out in a controllable way,

so this may be a future upgrade?

 

Any thoughts around my mods would be appreciated.

I expect you may make 215bhp following the remap. 

 

220bhp may be a bit optimistic. An exhaust on mine with a decat and injen induction made (best guess comparing to what a stock car made) 10bhp more and an extra 16lb/ft of torque.

Thanks for that Lauren,

did your car make around 205bhp at the Tuning Developments meet with just an exhaust?

 

Adrian will be working his magic on the ECU cum the 1st week of June.

I made about 15bhp with just a remap on standard exhaust. 220-225 is what I'd expect with full exhaust system on top. Depends on how it's mapped though.

What you'll find with Adrians map is that he will improve the mid range torque dip for a more drivable car rather than a all out max BHP as he does on the road mapping rather than on the dyno mapping (not saying one is better than the other though Mark  ;)  :P )

I'm hoping for somewhere around the 210 - 220 for NA, unless I decide to try those Crawford power block things, look to be a good option for staying NA and increasing power, although they will just move everything up the range...

 

Anybody that has had the inlet manifold off for one reason or another (looking at you PD supercharged guys if you still have the manifold) fancy sending me the 10digit part number off it? I may be able to pick the drawing up so I can CAD my own mani spacers :D

I'll pop up in the loft and get it for you tomorrow if I remember.

The Crawford blocks are good if you're happier with a shortened rev range.

I've got a decent basemap for the Crawford bits should anyone require it for tuning.

Well, well....

I just fitted my used HKS exhaust today,

and wow......

seems quieter than standard rear section on tick over and sounds like a sports car when you give her some beans,

never aware of big bore=big noise!

 

As an overview, the pipework is not that much bigger than standard,

but it is not crushed on corners,

the back box is slightly smaller

and the rear cans are huge!

 

The exhaust noise sounds very TUNED!

Kind of like what Porsche do,

maybe a placebo effect?

 

So far I have only run 5 miles on back roads, so no high revs or motorway cruises.

 

I would say that HKS have spent a lot on R & D,

rather than make a large diameter pipe fit under the car and take the attitude that all noise is good noise!

Hopefully the sound will be a good sound to live with........(don't talk too soon).

But there is a price!

 

Over pipe £100ish

Cat delete £170ish

HKS £1000ish

James has the HKS and we gave it some beans on my driveway the day before BHP and went out for a little drive. Sounded good, quiet til you put your foot down and when you did it sounded well crafted.

After a week I am aware that torque has increased since fitting the HKS exhaust.

 

On another note....bum....bum

I was stopped yesterday for an illegal number plate as shown in pics

and was warned that I had incorrect spacing.

 

On the face of it,

I was given a verbal warning and told to change them

and was made to feel lucky that it was not made an offence with ticket!

What is my position with regard to a verbal?

Is it recorded on the PNC?

Am I only liable if stopped by the same policeman?

 

Any advice (not sympathy) would be much appreciated.

 

Thanks in advance

Got a phone call from Toyota today to say I had won a trackday,

details of which are:-

GT86 owner track day – Oulton Park 5th June 2014

 

Itinerary

Please aim to arrive at Oulton Park between 07:30 and 08:30. You will be directed to the Fogarty Moss Centre to sign on and register, prior to the safety briefing.

 

07:30 – 08:30                           - Guests arrive and sign on at Fogarty Moss Centre

08:30 – 09:00                           - Safety Briefing

09:00 – 13:00                           - 1st track session

13:00 – 14:00                           - Lunch

14:00 – 17:00                           - 2nd track session

17:00                                           - Track closes

 

Location

Oulton Park Circuit

Little Budworth,

Tarporley,

Cheshire CW6 9BW

 

What to bring

Please ensure that you bring the following items with you on the day:                 

·       Both parts of your Driving Licence

·       A completed Car Track Day Registration Form (attached)

·       Your GT86 track Day event pass (attached)

 

What to wear

As all activities will be taking place outdoors, please pay attention to the weather and come dressed appropriately. We also advise that you wear comfortable driving shoes or trainers.

 

Please note, you will be required to wear a helmet whilst driving on track.  Helmets will be available to borrow free of charge from Oulton Park.

 

Guests

All registered drivers/owners are permitted to bring one guest. However, please note that no one under the age of 16 years old is allowed at Oulton Park

 

Track Signing on
All drivers and passengers will be required to sign on. You must produce your valid fully unrestricted UK Driving licence (photo card or old paper licence) or its overseas equivalent at the time of registration; please note that photocopies cannot be accepted. Participants under the age of 18 will require their parent or guardian to be present, and to countersign their indemnity form.

Noise Testing
All vehicles must conform to MSA current silencing regulations and will be subject to testing before taking part in any on track activity. The noise limits at Oulton Park are 105dB(A) static, 85dB(A) drive-by. The initial test is a static test which is carried out using a handheld meter.

 

Safety Briefing
A full safety briefing will take place prior to track activity; this briefing is compulsory for all drivers. Should you arrive late, please report to one of the organisers and arrangements will be made for you to be individually briefed.

Sighting Laps
All drivers must complete sighting laps prior to track activity. These are an opportunity for you to familiarise yourself with the circuit at a reduced pace.

Passengers
Only one passenger may be carried in the vehicle at any one time. All fitted safety devices must be able to perform within their manufacturers guidelines i.e. weight and height of passenger must not interfere or prevent such safe operation within the manufacturers design parameters. Passengers under the age of 18 must have the appropriate section of the Registration Form signed by their parent or legal guardian.

Insurance
We do not require you to have insurance on trackdays and it is unlikely that your normal car insurance policy will insure you. To clarify this, you should contact your insurers. If you explain that the events are non-competitive, they may insure you for a small premium. Alternatively, there are specialist companies who provide track day insurance.

When taking part in a trackday, you do so entirely at your own risk.

You should always keep your car regularly serviced and in a roadworthy condition, but for the avoidance of doubt please note the following recommendations:

Tyres
Your tyres are your only contact with the track. They should be in good condition and set at the correct pressure. You should check your tyres regularly throughout the session for wear and damage; tyre wear will occur considerably faster than you would experience during normal road driving. Do remember that cold tyres do not have as much grip as those that have warmed up.


Brakes

Your brakes should be in good condition when taking to the track. Brake pads should have been bedded in for at least 100 miles. Again, your brakes will wear much quicker than on the road and you need to check them regularly throughout the event.

Items in your car
A simple tool kit is handy to have with you but before you go on the circuit make sure that you remove everything from the car that is not firmly fixed down. Pens and soft drinks cans can become lethal projectiles. Also make sure you remove everything from the boot of the car.

 

 

Fuel
You must ensure that you have enough fuel at the start of each session. You are likely to use three times as much fuel as normal road driving. If you run out on track your car will be removed to a safe position, but may not be returned to the paddock until the end of the day. This is an unnecessary disruption for other track users and consequently you will not be permitted back on track that day. Additional fuel is available to purchase at Oulton Park.

The end of your trackday
At the end of the day you must ensure that your car is roadworthy and legal - check tyres and brakes, remove tape from lights and return any settings that you have changed.

Track Notes

  • On entering the circuit please keep to the right hand side and do not move over until the circuit behind you is clear.
  • Use the first few laps to warm up your tyres and familiarise yourself with the location of the marshal posts, etc.
  • Consider other drivers - Leave plenty of space when you overtake other cars.
  • OVERTAKING is on the LEFT ONLY and on the straight sections as detailed in the drivers briefing on the day.
  • It is good etiquette for the driver being overtaken to 'lift off' (do not brake) to assist the overtaking vehicle.
  • TYRE NOISE AND DRIVING STANDARDS. Any driver generating excessive, unnecessary or constant tyre squeal or is deemed to be driving recklessly or in a manner considered to endanger themselves or other track users will be black flagged, removed from the track and given a warning that such driving is inappropriate. If the driver continues to give cause for concern a second black flag will be given and he or she will be denied further access to the track for the rest of the day. Deliberate and excessive power slides will be dealt with in exactly the same way.
  • In case of an incident, leave your vehicle and move to a safe position behind the barriers. If you see an incident, do not stop unless it is unsafe to continue.
  • Anyone who ignores red flags or the direction of marshals will be asked to leave the venue - the marshals are there for YOUR SAFETY.
  • The medical car has a paramedic on board and will join the circuit via the pit lane. Please be aware that the medical car has the right of way on the circuit and will overtake on the left so please move over to the right.

On track we use certain flags to signal to all drivers. When you are on your sighting laps on track please familiarise yourself with the position of the marshal posts. The following are the types of flags you will see:

Waved Yellow - Danger ahead, possibility of incident or hazard, reduce your speed by 50% (check mirrors first) and no overtaking.

Red - Incident has occurred and the session has been stopped. Please instantly reduce speed by 50% (check mirrors first), pull over to the right to allow recovery vehicles to pass and return to the pit lane. NO OVERTAKING

Blue - The vehicle behind is trying to overtake - please drive on the right hand side of the circuit

Yellow & Red Striped - There is a spillage on track or change in the track surface or condition, i.e. oil, mud, debris, etc. Reduce speed and take caution.

Black - There is a possible problem with your vehicle, i.e. damaged bodywork, losing fluid, etc. It could also mean that we need to discuss an aspect of your driving. Please return to the pits immediately and report to a marshal.

Chequered - this signifies the end of the session. Please reduce your speed and return to the pits at the end of your lap. No overtaking is allowed during this lap.

Pit Lane Notes

  • If you are using a garage, please ensure you adhere to all the terms and conditions displayed therein.
  • The fire lane at the rear of the garages must be kept clear at all times.
  • Please note the pit lane is strictly one way, as is the track. All traffic must travel in a clockwise direction. The pit lane speed limit is 30mph max.
  • The pit lane must be kept clear between the yellow line and the pit wall to allow emergency vehicle access.
  • Only people taking part in the current session are allowed in the pit lane.
  • It is forbidden to sit on the pit wall.
  • It is forbidden to re-fuel in the pit lane.
  • It is forbidden to store fuel in the garages or in the pit lane.
  • It is forbidden to smoke in the pit lane or garages.
  • Children under 16 who are not participating are not allowed in the pit lane or the garages.

With regard to noise,

I have a 2.5" overpipe plus,

my car is decatted with a resonator fitted to a 2.5" pipe

and a HKS system at the rear.

 

I am booked into Fensport for an ECUtek tuneup prior to the track day,

will have to check to see if they have a noise meter?

Congrats and enjoy, have you been on track before?

 

Also verbals are not recorded, running illegal plates just isn't worth the hassle. The spacing is there for a reason so that the ANPR can do it's job properly. I had a copper pull me over once claiming i had jumped a red light when i didn't. Got some gory pictures out and I was like.. we'll that's great and all that but I didn't jump the light. He got bored and let me go eventually as he knew he was powerless.

You will be well within noise limits with the HKS. It's around 96db

Congrats Stephen!  And what a load of horse poo, I've seen plates with almost italic writing and not really that legible.....how on earth they get away with it I have no idea, instead you get pulled for something that is pretty legible no problems....just with a bit more spacing....wow big deal  <_<

Enjoy yourself Steve, if it's your first track day makes sure you don't turn in to early or you run wide on the exit, take it slow at first and enjoy yourself as you have all day.

I'm really really jealous

Might take the day off anyway and come down to see if I can get in to watch (and bring my lid if anyone isn't taking a passenger)

Thanks for the comments.

 

Last track day, was a couple of years since Nurburgring.

 

Maybe try to get a travel lodge near to Oulton Park?

 

These are some stats for the exhaust

and Fensport may have a noise meter?

Does anyone do half placing on number plate digits?
