Just spray it for now.. Purchase all the safety stuff and you will be fine.. You can get you a nice H/C package and get 420rwhp. No one has gotten 450rwhp from a H/C package in our area. NO ONE!!! Dont believe what you read on the boards. Most of those dyno #'s are hyped and they do everything possible to get 440rwhp plus. The thing is when they do that you cant drive the car around like that because it is most likely too lean and any little slip and your motor is gone.
