help needed on my dyno run hello guys
i just finished tunning my z28 so tell me what do you think about these numbers.
my car has an lt1 with 8.5 CR pistons, H beem rods, cam,long tube headers,throttle,75lbs injectors and procharger running11 psi.
my first q?
1-why do i got max rpm at 5200 how ever in the car i run it up to 6200 rpm ?
2- i have the spark advance at full or neer full load set at 34 dgree and i have no knock is that safe?

Your torque was falling off as expected, but it looks to me like your hp was still slightly climbing. You will have to ask the dyno operator why they quit the run so low.
Your compression ratio is low for a centrifical supercharger, which is probably why you can run so much timing. I would add several more pounds of boost and pull some timnig out of it. Adding more boost will get the blower producing boost sooner, which will make the car much more responsive. Bob
