I haven't even picked up an SRT yet, but am actively looking for a nice, clean SRT roadster, and being a motorhead, I'm already trying to envision the engine mods

I assume the biggest bang for the buck is the supercharger pully swap to increase boost, ECU tuning to reprogram for the pully swap and fine tune the computer, swap the air cleaners for K&N's for better breathing and possibly exhaust ugrade to up the breathing as well, is that basically the general consensus ?

How easy (how costly is it may be a better way to ask) is it to squeeze 400HP from the SRT engine ?

Thanks,
Brian
