This sole intent of this thread is to give feedback to those researching the heads and cam. I built this car as a streetcar, not a max effort build which is why I may get questions on why i didnt dump the exhaust or run a fast 102 or MSD.

Bottom line is the car runs hard.

Kooks 1 7/8 flowmaster y (catless) into 4" merge, magnaflow catback. (Full Exhaust)

This is with stock fuel pump and injectors. Stock 10 bolt. Stock clutch. We spun it put to 6100 RPM as an FYI.

Thanks to the guys at TSP and special thanks to Timmy2Stage at Sound Performance for tuning the car.

 

Was the car still making power at 6100? You said it was a street car but I probably would have ran it out longer?

 

Agreed. The stock injectors couldnt keep up. At some point ill swap out to larger injectors/pump and run it out farther.

 

470 rwhp combo if spun to 7000

 

500 easy once u get proper fuel pump/injector and spin to 7 on a dynojet

 

That setup should peak around 6300 or so. Did you ever re-dyno or run it at the track?

 

Not yet. Life has gotten in the way lately.

 

any updates?

 

^^ What he said.

 

Not a chance. I had a very similar setup, they don’t peak that much higher. 63-6600 tops. 500 rwhp isn’t easy... especially when guys are getting inflated dyno numbers, claim 500 to the tire and trap 117 mph.

 

we used prc 225s and polluter v3 cam and vengeance racing fast 92, ported ls2 tb, on a iron 6.0 in a c5z and made 494 with ls6 maf. need to get rid of the 85mm maf and maybe break 500
