i hate to go off topic here but i think you got your answer from the other replies....

You got to 365 whp with just intake, TBE and a reflash to 27psi?

 

Yeah, I'm going with S2s

As for my car, yes. The car only has HKS intake, Perrin TBE, walbro 255, TRE stage 3 tranny and ACT street clutch. I don't know if the tuner is that good, the car is a freak or a combination of both, but I sure like it

 

There is alot of good choices. I have kelfords 272 and I like them.Other good choices are gsc s2 and cosworth m2.

GSC S2....Close Thread.

 

love the Kelford 272's. You'll forget all about lag and notice how nice the car feels pulling all the way to redline.

 

cossie m2s...great results...fairly inexpensive

 

After taking a ride in your car and you telling me the gains I'd have to agree 100%

 

kelford ftfw!

 

S2's FTMFW

 

I'm another IX who's very happy with the Kelford 272s, perfect combination of spool and top end power. I'm running a BBK Full with pump gas.

 

Just flip a coin, heads S2's, tails Kelfords
