I'm still tweaking the tune, but I got some dyno numbers today on a dynojet.
439.48 rwhp SAE
400.77 rwtq SAE
1.27 HP / CID
1.16 TQ / CID
Conditions: 94.42*F, 24.45 in-Hg, humidity 4%, SAE correction 1.26
Once I get my tune squared away shouldn't have a problem getting over 440rwhp. Quite happy with over 400rwtq out of my N/A 346 LS1. I'm running 19 to 23* total advance 4400+ on 91 octane with 10% ethonal (mile high gas)
The basics for this LS1 with 6,600 miles
AFR-205 heads milled down .016 to 62cc
Cometic .040 head gaskets
10.9:1 SCR
Flowtech StreetSweeper camshaft
7.400 pushrods
FAST 90mm intake
Holley 90mm TB
ASP U/D pulley
Kooks 1 3/4 LT headers with cats
SW dual 3" turbo exhaust (2.5" core "quiet" mufflers)
90mm/4" intake tube and 2005 LPE filter/pannel
Speed Density tune
Tex clutch
Coming soon:
Ported FAST 90 intake
3" core higher flow SW mufflers
Might try without cats
Tune
Pushrod length and lifter preload check
