hmm, Interesting reading. I just have a hard time believing that a pvc trap can add that much fuel mileage. But I have never tried it either. I may build somthing of the like just to find out. I have heard other statments about water injection helping to. Cool reading slayer! Hey Brad, Is that webber one of the rebuilds from Stovebolt or is it a "webber"? What intake are you running, and have you tried different jets?
