    Thats a vague question. How fast do you want to go? If you want a good improvement in acceleration, reaching speeds of 75mph or so, while maintaining reliability and keeping it simple- do the items Bigdaddy mentioned along with an X charger.

    you have to much power for the prop... with your set up you are probably at 8200 rpm's which is the rev limiter... you want about 8100 for the best speed. with air intake you are adding a 100-200 more rpm... but rpms mean noting if you are at the rev limiter, you need to pitch the prop so it grabs more water creating more speed... do you kinda get what i am saying.

    fast as possible with a stock ecu is around 79/80 mph with a rude2.

    Only a VERY select few have gone faster.

    If 78mph is satisfactory- go Rude1, 42# injectors, RRFPR, call it a day. Excellent performance value for the cost.
