i have the s1 kit with the 2.5" downpipe/spipe at what hp range would u suggest getting a 3" ?

 

any hp range

 

thats what i was thinking cuz i kno on stock turbo cars a 3" dp does ALOT.. wonder why dezod gives away 2.5" though.

 

i have a 2.5 maybe ill step up to a 3 but then id have to re tune and thats cash money,.,

 

Do it when you step up your turbo... other wise it may not be worth the extra effort and money.

 

if you did a 3" s-pipe, would you have to get it retuned?

I would say leave the 2.5 DP and just go with a 3" S-pipe to add to your 3" s-pipe back p-tuning.

 

Yes get it retuned.. your spool-up should be a bit different - and top end HP will be different.

 

ehh then theres not really a point.

 

are you going to up the boost in the future, or swap to a different turbo?

 

who me? im upping the boost to like 16 psi after my car is done.

 

16psi!!! I think a 3" would be a good thing with that high of a boost application.

 

It wouldn't hurt - but for the work involved, might as well do it when the turbo is upgraded. Why go from a 2.5" DP (which is only like almost 3 feet of piping) to a 3.0" and gain 10whp (guesstimate) at 16psi when you can up the turbo AND the DP and gain a potential 50+whp or even a lot more?

 

B- Real,

He should also up the s-pipe from 2.5 to 3 inch?

 

3 inchers look hot




mmmmm

 

Yes! Definitely do that if you're doing the DP.

 

ya i got my eye on that t3/t04 f2 dual ball bearing turbo by innovative. thats my next thing after i get all the engine work done :X droool over that turbo..

 

i would recomend a el mani to

 

ya but thats alot of work.. and time.. and hassle.. and then id need a custom DP and alot of other ish.

 

you were talking about a new dp already so whats the diff lol lets face it it looks hot

 

haha ok ok ur right haha.
