it seemslike eveyone that is going past 13, 14 lbs of boost with no airpump and streetport is blowing there engines. what I want to know has anyone had a lot of mileage on a streetport with 15lbs of boost with stock twins? if so do you have your airump? and did you get it dynoe tuned at rotayr shop, etc?

I am thinking it is probably a necessity to get it dyno tuned when runnign high boost, eveyone else seems to be poping engines. I just put in my new engine last night want to make sure it satys in there

Thanks

 

About 4K on a streetport at 1.0 kg/cm^2. I doubt you'd call that "lot of mileage". Running great, basically using Chuck's maps.

No airpump and a J&S FWIW.
