hello, I'm planning to add some performance upgrades to my car (evo 9 MR) and I was wondering, how much WHP can the stock FMIC handle because I want to prevent detonation. Thanks

 

There are better ways to prevent detonation, also WHP depends on the dyno you're using, correction factor etc etc. The stock evo 9 intercooler can keep up with high boost levels rather well actually. You can make good power while on the stock turbo and stock intercooler. You should do some searching and find the numbers you're looking for.

 

Theres still evos with stock fmics?? lol. Not sure, but i think the stock fmic is good for about 330-350whp, after that i think it starts heat soacking. Thats my opinon tho, not a fact.

 

+1 This is where I'm at...Dyno session cut short from heat soak
