USACHMP, I am just curious as to what RPM your shifting at? Because with your pulley combination (got it off your other thread), I just wanted to point out that you are probably pushing the impeller to max speed with that YSI and are only seeing 20psi. Correct me if I am wrong, but at max impeller speed you should be somewhere in the 26psi range. I know that boost is only a measurement of resistance so if your motor flows a ton of air it won't be as much. But you have a 2V motor so I would expect you to see more boost than that. I garauntee that you are losing 4-5psi through that intercooler. I have a buddy with around the same HP in his 2V and he was losing 4-5psi through his. He was able to switch to a Treadstone unit and doesn't have to turn his blower so hard anymore to make the same power. May be something you might look into if it matters to you. Just a suggestion. Very impressive numbers by the way!
very interesting. you have a good point. I have always had lower than normal boost numbers in comparison. I have a stroker motor so i know that soaks up a bit of the boost and long tubes and cam but you bring up a good point. i will look into a more effecient intercooler.
