Hey guys

I need some opinions in what to do next. I've had the same set up now for 1.5 years without a single issue. I'm looking for a bit more power now and have a few options I've been exploring.

Current set up:

Stock block IX
FP Black
Cosworth M2's
ETS 3.5 ic/pipes
RC 1000cc
Walboro 255 single
Invidia O2
Works dp and test pipe
3" exhaust
Stock tb
Stock im
Stock exh mani unported
E85
484 whp and 444 tq @ 28 psi

When I was being tuned, it was not making power above 28 psi so it was left there. My tuner advised something was restricting power up top. Injector duty cycle was not maxed out yet.

I can't really decide between upgrading the cams to GSC S3, Full Race pro stock tubular exh manifold, ported intake mani and throttle body. I can't really afford to do them all but will eventually upgrade. I'm just trying to figure out what to do 1st and be the best cost to whp ratio. Any thoughts? Thanks guys!

 

are these dynojet #'s? Pretty impressive that your motor stayed together for 1.5 years with 444tq. More power to you (pun intended) lol post up a dynosheet if you have it. As far as making more power up top I would def say upgrade or at least port the stock intake/exhaust manifolds.

 

You may want to consider holding up for a while for a built lowend if money is an issue today-- you are at the threshold of having a bottomend issue with the numbers you are pulling. And that little escapade will cost 5k easy. just a thought-- GL with your goals.

 

I baby my car lol! Here's the sheet:

 

o2 dump, and switch to speed density

 

Good point. I'll give it some thought.
