Re: Mustang majic dyno run.

At the time it had a prochamber with MAC cat back, 3.90 gears, C&L cold air and a 125 shot. The numbers would have been better, but my fuel pump pegged and we kept it conservative. My AFR is really fat too. I wanted a small margin of safety. More has been added since then. I'll have another run once the new engine is in.

:beerchugg:Thanks guys for the compliments. Sorry about the vid quality though.... I hope a bunch of us can get together at the drag strip some time soon. I was at island last friday. I had all sorts of trouble hooking, but I managed a 12.1 @ 118 mph with a 1.9 60'. I know I can do waaaay better than that, I just need practice!

Your fuel pump pegged, and you kept it rich....So lean it out to a reg a/f of about 11.5 on the spray and that will also take the load off the fuel pump so it won't peg :)

Fuel pump was running @ 90% DC. I've since upgraded to a GT supercar pump. I kept it rich to keep it safe. I'd rather sacrifice a few HP and gain longevity rather than race a dyno and risk a lean out. Fuel quality and changes in climate lead me to this decision.

Nice ride. I still haven't run nitrous threw my car. I think its the parts where I have to keep refilling the bottle. I am way to lazy for that.
