402ci Fast 90mm AFR 225's Results Heres a list of what is in my 01 C5 Coupe...
-LS2 Block w/ ARP main studs.
-Lunati Non-Twist 4.000" Stroke Crankshaft
-Callies Compstar 6.125" Forged 4340 Rods.
-Diamond Forged Pistons 4.000"
-Comp Cam 242/250, 112 .600 Lift
-Morel Lifters
-Rollmaster Double Roller LS2 Chain.
-AFR 225 Heads CNC'd w/ Hollowstem valves, Upgraded Springs, 65cc chambers. Flow 316/238 at .600 lift
-ARP LS2 Head Bolts.
-Cometic Head Gaskets .051
-Hardened Race Bearings.
-Heavily Ported LS6 Oil Pump and Shimmed Up for Max Pressure.
-FAST 90mm Intake (Ported by Tony Mamo)
-LS2 TB (Also done by Tony Mamo)
-MSD Wires
-Vararam Air Intake
-Stainless Works 1-7/8 Headers w/ 3" X-Pipe
-McLeod Street Twin Clutch
-McLeod Aluminum Flywheel
-RPM T-56 Transmission
-3.90 Differential w/ all internal goodies
-60 # Motrons
Dyno was done on Drag Radials and they only did a few pulls on it. It was on a Dynojet, it started getting late and they said the car was too loud they didnt want to do any more pulls until tomorrow. Engine was built by SLED28 and installed by Backstreet Performance.
520 RWHP 484 RWTQ
11.41 @ 124 on base tune w/ 1.8X 60 ft
They also said they havent had any detonation at all and there is still more tuning to do to pull out a few more. The car has been down for 5 months and it has old gas in it. They are going to let me put a few miles on it, get fresh gas, and try to find a good fuel pump for it.

Great numbers! Be sure to change your fuel filter after you run your tank of fresh fuel through. You'd be amazed how fast gas can get old just sitting in your tank.
After you get the combination all dialed in, be sure to post up a graph!

Those are some very nice numbers especially with those 3.90's back there. What is your compression ratio with that combo? I need to convince my uncle into switching over to AFR 225's on his 402. He's not making as much power as yours but some AFR's woukd help.

Im having Drivability Issues, under 2000 RPM is stumbles and isnt smooth. Riding out the clutch is hard, wants to stall. Anyone have any advice for tuning? I am running 60# motron Injectors and stock fuel system. I have someone that will trade me plus $ for Motorsports Green Tops.
