The ususal bolt ons- headers, exhaust, intake typically gets us no better than about 180-185 FWHP. Like to see some ways to get us up to say 200FWHP (about 240 crank HP) with the N/A 2.5L. I think the key(s) is..
1) hotter cams
2) increased compression (ideally using stock pistons - milling heads, thinner head gaskets, filling/reshaping combustion chambers?? if possible.
3) A good ECU upgrade, custom tuned and/or programmable.
I think this is personally doable. Would like to see SHO-Shop or somebody pave the way. Any interest or thoughts on this (or does everybody just want a 3L)?
Dan, I have been researching how to get more power out of the 2.5 for a few months now. I think we could actually get 300HPfwhp out of the 2.5 engine without turbo nor supercharger.
Pistons, cams, rods, and bigger oil cooler would have to be upgraded for sure. I am going to talk to a few former Nascar engine builders that I work with on how to obtain the HP I want.
