compression, with a stock ls head and i made 132hp to the wheels and thats with an hour of dyno tuning and the motor only had 1k miles on it when i dynoed it, i rebuilt it and swapped it in and then dynoed it(i know the head makes alot of difference, but an ls head, no matter how built it is will never be worth 50 hp).......with your low compression and depending on what type of cams you are running(crower i would assume for a good ls n/a setup), i say you will make a MAXIMUM of 150HP if it is tuned by an extremely talented tuner , and thats pushing it, and that short ram intake isnt doing shit for you except making a sound, your clutch isnt gonna create power, its only gonna hold the power that your motor is capable of making(but i highly doubt your stock clutch would slip with the low numbers that are being made), and that throttle body isnt doing shit either unless you can pull lots of air through the intake and flow it out just as fast, 70 is way to big for your motor, air velocity has alot to do with power.....you might be making 180 to the flywheel, and i highly doubt that as well, but i guarantee you dont make 180 to the wheels on a naturally aspirated ls motor with only a built head.......

Re: 90 integra ls needs to just adjust cam gears for racing.
you need to put it on the dyno to see where your gears should be set. thats the most effective way
