495hp 491ft/lbs @ 7psi thru an AUTO (A/F-11.8-12.0, timing only @ 17 degrees)
600rwhp/605rwtq @ 10psi thru an AUTO (A/F-?, timing @ 21 degrees)
LT1Boost Header Kit (stainless)
1.75" headers
3.5" DP
TC78 .96 A/r
40mm JGS Wastegate
60mm JGS BOV
4" A2A IC
3" cold side
383ci
230cc Brodix LT1 Cylinder Heads w/62cc Chambers
ARP Undercut Head and Main Studs
CP Pistons -24cc
Manley 5.700" H-Beam Connecting Rods
Callies Billet Steel Splayed 4 Bolt Main Bearing Caps
Callies "Stealth" 4340 3.75" Stroke Crankshaft - Internally Balanced
224/224 .577/.582 114 LSA
are Siemen Deka 80lb high impedance injectors.
Tranny is a built 4L60E with a 2800 stall.
Rear end is a 12 bolt with 4.11 gears.
Compression ratio should be around 9.2:1.
Cam is a little small, but I suggested that he get the 1.15A/r turbine housing swapped before changing out the cam (make sure the .96 a/r isnt choking those heads).
looks like he had boost creeping up to 14psi right when he made peak power, but the powerband was already done at that point.
