Vengeance Racing 440 LS7 C5 Z06 Dyno Results/Idle Clip Inside
Finished this one up Monday guys. Pretty happy with the results......
Customer Car- 03 C5 Z06
Modifications Include:
Vengeance Racing 440 LS7 Shortblock- Callies Crank/Callies Rods/Wiseco Pistons/Clevite Main & Rod Bearings/ARP Main Stud Kit
TrickFlow 245cc CNC Cylinder Heads- Upgraded .650 lift springs
Vengeance Racing Custom Camshaft- 254/258 .623/.623 112+4
Yella Terra Ultra Lite Roller Rockers
Comp 850-16 Lifters
IWIS Single Roller Chain
Melling Hi Volume Oil Pump
ARP Head Studs
GM MLS LS7 Head Gaskets
FAST 92mm Intake Ported by Vengeance Racing
GM LS2 90mm TB Ported by Vengeance Racing
FMS 42lb/hr Fuel Injectors
Meziere Street Pump
ASP Pulley
Kooks 1 7/8 x 2 x3 Stainless Longtubes with ORX
DMH Dual Electric Cutouts
Corsa Catback
Textralia ExoSkel Clutch with new Hydraulics/speed bleeder
3:73 Diff
Installed/Tuned by Vengeance Racing
Compression 11.8:1
Timing 26*/Air Fuel 12.6-12.8
PUMP GAS
Final #s after a brief break in are 603rwhp/563rwtq SAE.... Unfortunately we have found the limits of the FAST intake. Map readings went from 98 to 93 from 4000rpm and up....We disconnected the intake tube and tuned speed density and saw no improvement in MAP readings. I think our customer is going to enjoy his new combo for a while and then head back over for a custom sheetmetal intake and larger TB. I am confident we can see 630s out of this combo on pump gas with the new intake and a few break in miles!!!

That is sick. It is amazing what the extra bore and cubes will do for a motor. Great work again.
P.S. I looked at my MAP reading and it goes from 101kpa to 97kpa. Not near as bad as this motor.

What do you think is the cause of the torque dip from 3K-4K rpms? I've been seeing a few vehicles lately, like one in this section, that have this same dip when using the FAST intake. Some say its over cammed, could be, not sure on this setup though, 440ci eats duration pretty well. Is it something with the fast intake? Maybe the stepped headers killing low-end torque? I would have expected at a minimum 450 rwtrq at 3K rpms, probably closer to 480 given the cubes.
