Well guys I finally got everything installed on my truck and took it to the tuner the other day and I am going to get it. I want to know what kind of numbers you think I will get. Here are my mods
Powerdyne blower 8 pounds of boost, 42lb injectors, 255 fuel pump, pacesetter long tubes, flowmaster exhaust, 98 vette heads and cam, ported throttle body, corvette shift kit, auburn posi unit. Just curious as to what you guys think I should put down I will let you know as soon as I get back tomorrow.

 

I'm gonna guess and it is a guess but i'm goin to say 358/363

 

well I got my truck back today I aint to thrilled with my numbers tell me what yall think 303HP and 375 FT LBS at the rear wheels

 

is it on a 4.8? Numbers seem kinda low for the mods. Who tuned it?

 

nope its a 5.3 and the numbers seemed low to me I aint to happy with them. I got it dyno tuned at delk performance

 

my stock 2000 5.3 dynoed 260 RWHP and 304 RWTQ. Those gains you should get with 3-4 psi and running really rich. I think something is very off. A 5.3 with your mods minus blower and a cam would put down more RWHP.

 

I agree I think that there dyno was off or something cause my truck bone stock was VERY STRONG, and I believe it has way more power than this now and so do all my friends. When I told them my numbers they all looked at me like HUH??????

 

doesnt a 2000 5.3 have 270 hp at the flywheel? so your only losing 10 hp to the rear?

is your truck intercooled on the powerdyne?

EDIT: I just looked at powerdynes website and it says their kit runs at 7 psi.

EDIT AGAIN: i just noticed that you have vette heads and cam on it. i could be wrong but i read somewhere that those heads dont have the right combustion ratio or something.

 

My 4.8 with the whipple, stock 98 corvette heads and cam, on 7lbs of boost put 309rwhp and 349rwtq and that was through stock exhaust.

 

I say turn up the boost, I'm sure you could with those heads.

Nice truck BTW. I like your hood.
