Hi there all. Now I'm sure you see these posts all day every day. If that's all your gonna say then don't respond.

Now, I have not taken my car to the dyno yet and won't be yet either.
I have a 99 FRC c5. It has a aes 390 lq9, 9.1:1 comp ratio, AFR 225cc heads, ls6 intake and TB, ECS big blower cam, vortech v1 t-trim makes about 12-13 psi.

However my two drawback are that I'm using stock manifolds and no meth. So, can anybody give me an idea? 500+? I know you guys can't guarantee it but I just want to see what ballpark I'll be in. Thanks!!

Since you are going to dictate what is an appropriate response, then how about this? You apparently do not know what the word "your" means.

Built 390 ci shortblock , nice expensive heads, blower cam, 12 PSI.

A stock 5.3 and a 75-80mm borg Warner will make 500 to the wheels at 12-13 PSI with a stock cam. If you can't make that much, find the nearest cliff and start over.

Hm ok. I should have said if YOUR comment isn't going to benefit my question or help then don't respond. Thanks dude bro.

Ha This does benefit me in a way. I know i should make more than a 5.3. Thanks!

LMFAO!!!!!! Thats awesome. But as far as a # i dont know how big a big blower cam is but i would still expect 600 if not reread above ^

To many things involved for an accurate guess, esp stock exhaust
Dyno's read diff to-tune, driveline loss, etc
But 500-650, somewhere in there-a wide range I know, but I would expect above the 500 mark at least

91 or 93 octane? I would say a handful over 600 if I was to guess.

What trans do you have? That also plays a factor in RWHP.

I think 500 even through an auto would be attainable. If you want an honest guess given the info you have, I'd say 540 RWHP through an auto, 570 RWHP through a 6-speed.
