Well as many of you know, I'm building my motor up, and doing headwork and cams as well. My question is this: how much whp should I be able to get at say, 11psi with the standard APS fuel system? I know Tuan got 506whp or something like that on stock heads at 11psi. I ask this because I was originally going to get Phunks fuel system and 650 injectors and have it all installed with the initial motor build, but that extra $2000 it'll cost me installed will sort of break me at this point, especially since I just bought new Volks and tires. So I'll just go without the new fuel system for a few months till my bank acct recovers from all this motor work!

 

Credit cards? PayPal Buyer Credit? Home equity loan?

 

Nevermind, I'm not gonna go through all of this and wuss out on this one part of it. I'm going all in!

 

With a lower CR like 9:1 or 8.5:1 it will take a few psi more than 11 to make >500rwhp, even with head work and cams. Tuan is running the OEM CR.

 

I just realized how much I've spent already and I'm not even done! I've since taken a deep breath, came to my senses, and decided to go as planned with the new fuel system.

 

you might just wanna wait for the APS big fuel and plenum setup rather than larger than the base 500cc Bosches and alternate return system , I expect it to offer superior headroom and performance when it is released, claimed to be in the fall sometime.

 

g3po hurry and get your motor in. I wanna see what its like. hahah.
