well i decided i was going too push it a little more ,i went from a 3.33 pulley to a 2.87 pulley nice difference in power.actually SWEET. NOW .what i didnt realize is now i have more backpressure and when im on the highway at 80-90 mph i seem too be feeling backpressure and i never did before,when i go too slow down i feel it bigtime .is this something too worry about ,if so how do i treat it?im pretty sure its normal when adding compression .do they make a blow off valve or something like that.any precautions or info would be appreciated.o im also obviously seeing higher intake temps.is this a major concern what are considered adequate ,safe iats at cruising speed or even in town with this kind of boost?thanks.am i damaging anything ?
