MartinT 514 Report post Posted January 21, 2021 I had a Sprintex supercharger previously (and several turbo cars) and preferred the progressive, more predictable and 'big engine' feel of a supercharger. The Harrop is a more grown-up supercharger with its Eaton core and intercooling over the Sprintex and is much quieter in operation (no whine). It also has no lag so, together with the excellent tune from Abbey, responses are lightning fast. There is some parasitic load but it doesn't affect responses and power is up by 50% to just over 300bhp which is plenty. To be honest, it just feels like it's a 3.0l engine. The combination of the excellent OEM feel of the Harrop kit and Abbey's attention to detail in the installation are just what I wanted for a car that is my daily all-season driver. 2 Jay Bamrah and Leeky reacted to this Share this post Link to post Share on other sites
BRZ-123 174 Report post Posted January 21, 2021 If you're driving hard enough to get the turbo that hot and then you drive into a lake, I think the turbo will be the least of your worries.... While the hot turbo, cold water scenario is possible, it is highly improbable. I haven't seen any "I wrote my turbo off driving through a puddle" threads on any forum.Very few will claim they did damage driving their car through water. That's an idiot claiming he is one. So forums will not abound with such feedback. I did say its not a hugely likely scenario but with a low car and potentially lowered , is not a brilliant design for a daily. Great for track though as low COG. Sent from my SM-G970F using Tapatalk Share this post Link to post Share on other sites

BRZ-123 174 Report post Posted January 22, 2021 Probably worth telling Subaru then I did tell them which is why they did not bother fitting that turbo engine to the BRZ in first or second gen even though they had to develop the NA variant specifically. For a high ground clearance SUV or even a rally car vs a low to the ground sports car, no comparison mate. Sent from my SM-G970F using Tapatalk Share this post Link to post Share on other sites

BRZ-123 174 Report post Posted January 24, 2021 Took me a while to find it ,this is the best review for FI kits with all sorts of data and slants just from across the Atlantic. Take your time and read it a few times over Jay. Edelbrock is very similar to Harrop as it uses the same charger Eaton TVS 1320. So reference it that way and enjoy making your mind up. https://dsportmag.com/the-tech/showcase/the-2018-86-challenge-presented-by-eneos/2/Sent from my SM-G970F using Tapatalk 2 surrey86 and Jay Bamrah reacted to this Share this post Link to post Share on other sites
MartinT 514 Report post Posted January 24, 2021 The only thing I will say is that the Edelbrock develops a lot less power and torque than my Harrop. However, the comments about road drivability are spot on. 1 BRZ-123 reacted to this Share this post Link to post Share on other sites

However, the comments about road drivability are spot on.It was tested on CARB California exhaust rules, so stock exhaust and both Cats intact . I think with that set up a Harrop would be ballpark thereabouts Martin. Dont you think so? Sent from my SM-G970F using Tapatalk Share this post Link to post Share on other sites

However, the comments about road drivability are spot on. Peak power is about the same as yours, I think. The graphs on the link are whp; mine was putting out 250whp at Abbey so pretty much the same as they got from the Edelbrock, Mark reckoned that was around 290-295 at the flywheel. Mine hit 199lbft, which is a bit higher than the link, although my peak was from a bump in the dyno curve around the 4500-5500rpm range. That's around the top of the stock torque dip, so you might expect a decat manifold to perform better there. Share this post Link to post Share on other sites
MartinT 514 Report post Posted January 25, 2021 My Harrop achieved 262whp which they said translates to "over 300" bhp. This is with the Rogue EL manifold.Sent from my LG-G7 using Tapatalk Share this post Link to post Share on other sites
Kodename47 446 Report post Posted January 25, 2021 Stock cars are about 160 bhp on the Dynapack at Abbey. Mine made about 170 bhp tuned but stock. Thing is, I bet that despite the headline figure the not being much higher, the torque curve due to the improved flow will be better. Either way, around 250whp on these is plenty quick and fun without becoming too much or requiring far greater grip to cope. Share this post Link to post Share on other sites
MartinT 514 Report post Posted January 26, 2021 I've just checked: my torque figure is 285nm @ 5100rpm (210lb.ft). Share this post Link to post Share on other sites
Luke 193 Report post Posted January 26, 2021 When I last saw @VAD17 in Bedford back in December the official fix for the cone filter neck breaking was to just use a shorter cone filter. @VAD17 makes subtle turbo sounds very OEM and power does feel progressive from the passenger seat. @MartinT Harrop setup looks incredibly OEM under the bonnet and makes it easy to tinker under the bonnet. As for what is better, I still can’t decide. 1 Jay Bamrah reacted to this Share this post Link to post Share on other sites
