Aaron 4.6 said:Well, its logically impossible to PROVE that something CAN'T happen, but I think trying to squeeze 300 rwhp out of a 4.6 2V using natural aspiration and no major induction changes is going to be close to impossible.
There's no reason why you can't get into the 250-260 rwhp range using most of the standard bolt-ons. However, at that point you still need to climb a fairly sizeable hill of 40-50 rwhp. Leaving the factory bumpsticks in place really cripples the potential to move your car past this power level without the use of forced induction.
Fundamentally, you are asking to increase the output of your engine by 70-80 rwhp using only bolt-ons. I think that's pretty unreasonable to expect.
