If the 8.6 would truly provide a 2lb increase that would satisfy me for now...(maybe).

Its a daily driver and use 93, just didnt want to go to much further than that and risk knocking and too much additional heat. Of course it'll be tuned too.

May upgrade the heat exchangers too.

You would need a 9.17" to get close to 2PSI. The 8.6 isnt going to provide much.


Also, your engine is a big air pump. If your moving more air in, you must move more air out or its simply not efficient.
