At present I have full exhaust mods from headers back on my RevUp. Car made 260 retweet’s @4.4K and 272 rwhp on DD @6.5k rpm before new parts that have and will be added. New parts are the MD art pipes, mrev2 , and spacer. My question is where do you think peak power will fall once parts are added will power drop off like a rock after 6.5k? Also has shelf Cobb tune if that matters presently til eventual dyno tune.

 

Highest I've seen on a NA VQ35 with every bolt on known to man (incl cams) was mid 310's. Gl!

 

Peak power is more of a function of your redline - the faster you spin the engine the more fuel you’ll process and the more power you’ll make (some exceptions to this).

peak torque (which you’re likely asking) will be around the same point in the RPM range and will increase with you’re future mods…peak torque is around 4500 to 5000rpm
