What is the highest compression I should run on Vortech V1 S trim 5.0 fox body 89 thanks Billy
Not to mention what heads you will be running.
tuning, tuning, tuning......... With the right tuning, it will be a beast. Personally Ive seen: 8.5 compression with 20lbs of boost run slower than a 9.5 compression with 11lbs of boost. Its all in the the timing, fuel and MAF tables.
