expected power LS1 - dyno this week just about ready to get my ls1 powered kit car dynoed at long last this next week. assuming its all running ok and the carb is setup well, what sort of power /torque could i expect to see from it? i'd be happy if it breaks 400bhp (flywheel) without any issues! I'm going on a dynapack which measures power at hubs (not wheels) via some adaptors that bolt to the hub.
spec is
LS1 (2000) 5.7l - ARP rod bolts
GM performance carb manifold
BG demon 750cfm carb (mech 2ndary)
MSD ignition unit driving std coilpacks. (6 different timing pills available)
tubular 4-1 stainless headers into 3" twin exhausts
stubby 3" hi flow sports cat (200cell)- (purely used to dampen ex. noise for trackday use and fill gap between headers and twin 3" oval backboxes)
220/220 deg cam 111lsa .510lift
comp cams beehive valve springs/retainers
comp cams pushrods.
billet lightweight race flywheel /triple plate super clutch
ATI super damper - runs alternator /dry sump/and water pump- no other accessories used
ARE dry sump conversion
15"x 3" oval air filter.
i think it should rev to approx 6200rpm safely maybe 6500rpm. is it realistic to expect a genuine 400bhp flywheel from this setup?

i was wondering if i should have gone for some headwork and maybe a wilder cam, but the budget didnt stretch to it unfortunately. if it does go 400bhp+ it will make me happy! i wanted to keep it fairly reliable anyway without hammering it too hard on track.
but thats just me Thread Starter

hi there
i had a few issues but it made 404bhp and 380+ft/lb at the hubs on a dyno dynamics hub pack system so i was quite pleased with the result. fuelling was a little lean (carb was re-jetted) but my fuel pump or regulator was playing up. also the edelbrock/msd ign unit is causing pinking under load on our UK fuel, so i am about to order the 6010 mappable unit instead.
