504whp with the Vortech 2.25L. 563whp with the turbo 2.1L. The article states they went with the supercharger instead of the turbo to try to save the transmission, which is still stock.

That was their claim during a past live q&a about their 2.25l kit that is on youtube from around a month back. They had a dyno for the turbo build in the video, don't think there was one posted for the s/c though.



I'm not one chasing dyno number, the desire for me in upping the displacement was to help mask the fact I lowered the compression for fueling without relying solely on high boost chasing heat issues.

I supercharged my gt86 and changed the radiator to Jackson Racing dual Radiator + oil cooler v2
I also added Mishimoto low temperature thermostat valve.

The temps are OK and well controlled 78-94°even under spirited driving but the moment I get into heavy traffic or idle it creeps up relatively fast to 100 degrees c°
So I thought it's not a brainer, definitely the fans are not pulling enough air through the main radiator, Air-conditioning radiator and SC intercooler.

I need your help on what are the best fans + shroud combo to ensure perfect cooling under lower speeds / idle.

Thanks in advance for your kind help

Is that temp bad? For clarification, this doesn’t happen all the time, right? This happens only after spirited driving when coming to a stop, right?

I went through and fitted, a few different cooling options, to get to the point I am at now (the cooling is now fully capable in any situation)

I started with fitting an external oil cooler (with its own fan) behind a cut out in the fog light area...with an air exit into the wheel well.

I fitted a Mishimoto radiator and their twin fans in their shroud.

This all worked OK until I put on the smallest pulley and a built motor ... then in very hot conditions, and under extreme use... the temperatures could rise to above 106c.

So I fitted a PWR radiator and twin Spal (high volume) fans, adapted into a modified and enlarged Mishimoto shroud. The fans draw power directly from the battery.

The functional difference is very very impressive.

I'm a fan of the fullblown rad+shroud+spal fans combo. For the price it is fantastic upgrade that directly bolts in with oem condensor and harrop intercooler while giving you greater clearance infront of the engine.

CSG fan shroud + fans.

It'll be MUCH louder than stock, closer to what you hear out of a ferrari or lambo, but will control your temps better.

Have your tuner lower your fan activation temp as well.

Many cars have a gulf spec version with enhanced factory cooling, but the 86 is not one of them.

Hi everyone I am currently running the 95mm Pulley on 98RON in Australia. Does anyone know if you can run a 90mm or even an 85mm with 98RON and standard injectors?

Thanks in advance

Your 98 RON is equal to our 93 Octane here in the States. So, yes, you can run the Harrop with the smaller 90 mm pulley without larger injectors with no problems.

However, if I were you, and if I wanted to step up to the 85 mm pulley, I would burn at least 100 RON or go E85. If you use 100 RON in that case, you still won't have to go with bigger injectors, but if you go E85, it is recommended that you go with larger injectors and a higher-flowing fuel pump.

Hi mate, I'm in Brisbane and ran the 90mm pulley on (BP) 98ron for about 3 years of very hard use, with standard pump and injectors with zero problems, after checking with Harrop at the time.

I stepped up injectors with the 85mm pulley on 91. The car wasn’t too happy on hot days with 91, so I went with E85.

Hi Guys,

I have asked in the other thread but no one seems to have an answer.

1) Anyone installed an intake snorkel to lower IAT or just keeping it stock?

2) My car is currently tuned for the SC with a Cat-back exhaust (stock header, stock front pipe). Is it "safe" to drive without a tune if I install a catless header with a high flow cat?

Thanks!

I cannot answer your first question as I am not running any type of aftermarket CAI. But, the Harrop includes an air to water to air heat exchanger to cool the charge air so the benefits of an additional CAI would be minimal at best.

To answer your second question: It would be safe to drive it that way, but you won't be able to make full use of the new header without a new tune, and you will start getting a CEL and diagnostic codes pop up also due to lack of the catalytic converter in the header. A proper tune will also disable certain codes from causing your CEL to illuminate.

Hi thanks for the reply

I am trying to get a little bit more out of it without going to E85.
Did you run a 95mm before the 90mm?
Just wondering what sort of difference in power and torque?

Is it a noticeable difference ?
