Guesstimate of whp I'll make? 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!!

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.

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

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.
