I'd really like to get up around 400 horsepower without spending almost $4,000 on the Renntech kit. Anyone look into a small nitrous charge? Shouldn't take much to get 70 more horses.

 

I'd be REAL careful using nitrous...I'm not sure if the stock fuel system is up for it, maybe different ECM, Holes for injectors in your intake system, etc. It could still be pretty pricey!

At least it's easy to tell if the nitrous system was working improperly...you'll have localized pains in and around the right hip pocket, and your engine will fit loosely into a 5 gallon bucket!

 

Someone has done it or will do it, no doubt.
I would not recommend it. You're running a hand-built supercharged engine here. The cheap fix for HP may cost you big bucks down the road.

My .02, play it safe and go with Evosport, SpeedInnovation, or Renntech, even though it is more money.
