Low on power? - ZR-1 Net Registry Forums

1990 quasar blue · 10-17-2005

I was reading through some threads and seeing some numbers of cars with similar mods. LocoBob's old 91 making 374rwhp, another guy making 386. I have ported plenum and injector housings by G.V.D., Flowmaster exhaust, HAT PROM, open lid, and a Coplon duct. The best the car has done is 355 rwhp and that was about a full point lean. I had it fattened up a little and now it's down to 350. Could this be a cam timing issue? The car seems to run good and pull hard but, the numbers just don't seem to be there. Any thoughts?

TIA,
Mike
