If my memory serves me any good there small like 2.0-2.25. Next time you have you bumper off just look at them there tiny. It does get a little bigger after it goes into one. But from a tuning stand point, the pipe being bigger after the fact is to late.

Blow through is how this car is set up from the factory ,and all the other aftermarket kits are designed on these cars. GTM TT Greddy TT GTM supercharger Boosted performance Mid mount S & R single turbo. Stillen is the only kit that is making the car do something it was not designed to do re-locate the maf's to the front.

Having the Maf's out front you cant read intake car temp with a long from uprev. They also max out at a lower HP level because of the size location/small pipe.

Blow through you can vent to atmosphere on our cars draw through Stillen set up you can not.

This is one of the reason's I sold the kit and did not put it back on my car with the built motor I am driving around with now.

I do think there can be more power had from the Stillen kit ,but you have to change thing's with the kit. Stillen is not on these forums anymore for support nor are they putting out any other stages of the kit.

Thanx a lot man,, So let me see if I get this. So I can just make the intake to the SC bigger 2.75 or 3? And move the MAF's to after the SC( But would have to split the pipes( Could use two 2 inch pipes). Or at least just make the pipe to the SC pipe bigger . I have the whole front of th car off now at the dealer, Thats why I'm even thinking about do this now the car is down and will be down for the next 2 weeks waiting for the SC to be fixed,.

I would love to Vince make the pipes for this but he only returned one of 2 emails and none of two phone calls. I'm sure they are busy with their own things but.. . . .

I would just make the intake bigger and keep the maf's there right up front, that way they can read the higher volume of air. Splitting the pipes after the supercharger would be a lot of custom work. You have to use the stock manifold have equal length pipes of the throttle body's to Air to Air intercooler.Thats a bit a custom work and would take someone knowing what there doing.

Just making the intake pipes bigger is simple and keeping the maf's where Stillen designed it.

Vince wasnt going to make the pipes for me I have a friend that does this kind of work.

The car is NA from the factory so it's definitely setup as draw-through. The presence of a compressor (SC or Turbo) in the system and which side of it the MAF is on makes it a potential blow through. When the MAF is post compressor it is blow-through, pre-compressor, just like an NA car, is draw-through.

OK , Thanx man Was thinking of staying with the Stillen mani tho there is another hear exchanger on there I would want to keep, So I will look into just a larger pipe to the SC then.

BTW I know Stillen is not on here , Why seems now one is really happy with them.. I'm in the middle with them right now, They guy I'm dealing with is mad cool, and helpful but overal just EH with them in general.

OK talking to a couple of guys on making the intake pipe bigger 2.75.

That's what you would need and put the Maf's housings right in them.

:tiphat:Making the while thing tho, Just seeing If I need to send them mine to trace or not.

Ok just got the word from Stillen, Everything is covered under warrenty, :) John @ Stillen has been really great, !!!

ok COOL Vortech is also doing the upgrade, Told me I had the SCI and they will be doing the SI upgrade? Anyone have info on that? Similar to the 928? I looked around the interent and only found it on a mustang forum, guys have good things to say, Boost comes in earlier in the power band.

Congrats on that great news. And :tiphat: to Stillen for working with you.

I know the car from the factory NA is draw through .I was just talking about how the kits FI are designed.


The SI is nice mustang guys use it and the E92 M3 supercharger kit made by ESS use it as well. Glad to here everything is covered for you man.

Hey Thanx man, Yea was reading alot on the mustang forums, Guys where seeing boost earlier, 2500 or so and it was doubled, Normally would be 3PSI @3k now seeing 5-6 PSI @3k RPM, If I can get something like that I would be very happy.

BTW my Stillen air intake has been shipped off to S&R this morning for tracing a "New " Upgraded intake 2.75!!!
