It was a nitrous car, figured I'd throw a blower on and see what happends. 10 psi with 50:50 meth on a mustang dyno.

Looks nice. How did you raise the compression to 11:1?

Grizzly_adams

thanks, originally it was a nitrous car I had the stock 243s milled down.

so you are on a 9.5 afr? what timing?

Grizzly_adams

noo afr is around 11.1 not sure why it says that haha timings at 11.5

maybe it was an error, but typically that's called a flexfuel tune. Your AFR with meth or e85 should not mirror gas only AFR. I say error bc if trully was rrading 9.5, that's on the lean side. Don't run anything less than that 50/50 mix.
