John M asked:
Got a stock EVO 9 MR, wanted to do some mods. I was thinking of a megan O2 housing, megan header, AMS FMIC, AMS Upper and Lower I/C pipes, HKS SSQV BOV, AMS TBE w/HFC, MBC to 21 psi, APR head bolts, and a dyno tune. What do ya’ think? Good/Bad? What do you think I’ll get to the wheels, and what qtr. mile should I expect? Serious answers and numbers please.
So long as the exhaust manifold(header) is equal length and you step up the size of the turbo( I think the stock size is a 16g, no? if so you might wanna step up to a 18g or 20g turbo, for the sake of efficiency at that kind of boost) you should be closing in on the 400 mark at the flywheel, I’m not entirely sure what it would be to the wheels since 4wd/awd dynos can vary so much, but with all that boost, get a turbo back(if street legal isn’t your concern, otherwise a cat-back), but yeah thats a pretty good engine tune for some fun with the local v8s, might want some brakes to slow that big boy down tho. (qtr mile depends a bunch on your suspension and tires to get that power to the ground, but here, this should help: )
