I realize my CFM numbers were incorrect....and I said that I didn't know the real #'s....it's the principle that I was trying to get at. The stock TB is not maxed, or close to it, at 350 rwhp......I know that for a FACT as I've been through this on 4 Vettes (only 2 of them were SC'd) and it never held me back even at 465 rw. So let's get to the point. The guy thinks he's missing 70 rwhp (and I agree that 420 rw might be optimistic) and that the TB is a problem. I'm telling him it's not....don't waste the money. You then posted that you saw "significant gains" by switching to the 58......so it seems that you're encouraging him to get the larger one. I'm betting he won't gain 10 hp if he does....unless there is a problem with the stocker and the butterflies aren't opening fully or something.

I'm really having a hard time following your 'point' with all your misinformation. 1st off, I never said it would land him 70 rwhp - I don't think he's even 'missing' 70 rwhp.... my guess is that around 30rwhp is possible with some tuning and a better intact tract that gets his MAP closer to 100 KPA. 2nd, a 58mm TB doesn't flow anywhere NEAR 1600 cfm - they are rated at 1000 cfm. The stocker is only rated at ~625 cfm[/b], which is fine for a stocker or bolt-on car, but small for a good H/C setup and inadequate for a stroker.

Furthermore, you are also incorrect when you say using an TB that flows more than the engine can consume will show 'absolutely no gain'. I see people say this all the time, and like you, they are wrong

. Although it might be small, there will be a VE gain from an oversized TB over a TB that flows exactly what the engine uses. [/B]

I am only getting 350 RWHP (shooting for 420 RWHP at least).

Are you getting 350 RWHP when using NOS? I noticed you didn't list any fuel upgrades. Maybe you need some larger injectors a fuel pump, and a good tune. Maybe the opti-spark is bad. It seems like your car can handle a lot of power with the forged parts and the 12-bolt, but it's not getting the fuel and air that it needs.
