In my case, I want a track proof car, so cooling is important.

I asked directly TTS for advices: they told me that : "For a C30-94 376 hp is quite reasonable. The intercooler is the restriction deliberately to limit power. So going to our Race intercooler would increase power". I am waiting for a quotation on the race IC, as I can't find it on the online shop.
Ok. We'll that's good to know. I've never seen the Supersport kit's I/C. My TTS Race kit's I/C has a tube and fin core. Excellent!

Good luck then!

Sorry 06S2k07Si you will be dissapointed
I have had already too much work on the car (full bushings change etc.), and it is on jack stands since 1 year now! (got a child)

So I have begun assembling the supercharger kit as it is, with no major modification: no big IC, no E85...
Just a few adjustments on pipings and fixations.

Here is how it looks when pre-assembled: nothing fixed because I have to run the car NA to the technicial inspection soon.



I am just going to take care about the intake: change this extra-small foam filter (don't like it) by a traditionnal one. And try to install aluminium panels to feed it only wish fresh air.
Also have to install the OCT, rotrex oil accessories, and engin oil cooler.

I hope I will have some time to finish the car in about 2 months (including mapping).

I tried designing some heat shields for the intake, which would look quite similar to the KN FIPK but adapted to my rotrex and pipings.



I think I will forget this idea: difficult to adjust, and not really sure about the gain it would produce...

^^ Yeah that is a dinky filter! Definitely a restriction there. What is the pipe diameter? I have a big brand new AEM dryflow which may fit. Or will with a coupler of sorts. I've got a couple other filters as well, which would require a 6" velocity stack coupled in-between to accommodate. All stuff on my shelf I don't foresee needing.

This rotrex is a C30-94 so the intaje pipe is 3". This pipercross foam filter is 3" inlet, but quite small overall and I don't like foam...
I plan to go with this K&N filter:

AEM dryflow filter are quite similair to this, I think ?
Do you think I should go to a velocity stack + bigger filter ?

My problem is the diameter of the filter base. Depending on the excat position of my silicone and aluminium intake parts, the filter is quite near the oem fan. I mesured that I should stay with a filter which is about 5.1 to 5.5" of base diameter , if I don't want it to touch the fan (and the heat shield, if I do it...). I guess the velocity stak solution will be bigger than that.

Last thing: do you agree that my heat shield prototype (K&N FIPK style) is useless ? or should I keep the idea of doing it ?

Actually, something like this may fit: the length of the inlet diameter adapter can help me move the filter away from the rad...
