    2004 Silverado ls1 Swap Dyno Numbers

    Well finally found a place to get the truck dynoed at, i dunno if i should be happy or disappointed. As of right now im pretty happy. The results where...

    351 rwhp
    370 rwtq

    It was a third gear pull on a dynojet up to 6300rpm's. He said i was running really rich. Soo does this seem accurate for the mods i have done in my sig?

    i would think you could pull alittle higher numbers out with alittle larger cam, but all in all those are some great numbers!!

    whos doing your tuning, maybe some tweaking would get ya alittle more hp and tq
    Simple: 408 on steroids!
    single digits coming soon!

    Nelson Performance is my tuner. The guy at the place said i would have more horse power if i wasnt running so rich. Does anyone know about how much HP is lost through the drivetrain? Just wondering about how much i have at the flywheel.

    Would anyone happen to have some stock ls6 dyno graphs from a cts-v or ws6?

    Thanks

    thats bout right for 20% loss with your mods. net to around 420 hp. which is typical of LS6 with headers
    2002 Lightning - GT headed 5.5Litre w/ Twin 7665s
    2002 Silverado - 427Lsx w/ Twin gt4202s
    2010 Silverado crewcab Z71 - 5.3litre w/ procharger
    2000 Wrangler - 5.3litre with some stance
    2014 Xsport- 3.5 Eco boost

    it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference

    Those are good numbers. Might get quite a few numbers by leaning it.

    Hey good you guys made me feel better, i wasnt sure if i should have expected more numbers for it being an ls6 basically just with a truck intake.

    Would a good cam get me up to the 400 range? I need some more horse power so i can woop some of you guys at SAR!!

    Any more opinions will be great guys

    You need to get a live tune with wide band. If you plan on going Turbo, or supercharged, I would keep that cam. If your going to stay NA, get an aggressive cam with a lower LSA, Higher lift and duration. With a good dyno/live tune you should see 370whp 395wtq. With a more aggressive cam you will see probably 425-435whp IMO.
