I have 9.5:1 compression. The only way my setup could be worse is if I had the pistons made with even lower compression. I need to get at least a stock exhaust or something. I have the stock exhaust manifolds ported out, the precats were cut off and are now 3" pipes ovaled out mating to a custom made 3" y-pipe, custom 3" back to the rear y with 2.5" to two race series magnaflow cans.
Last night I took the stock maf electronics out of the housing and put it in a housing that came from a Grand Marquis 4.6L. The sampling area is the same exactly but the diameter has to be at least 75mm, maybe 80mm. I don't know if it helped performance but the butt dyno didn't feel any losses. I am probably going to sell the car to buy my lady a new car but I want to drive it for a bit at least.
