waste gate question
since i put twins on the super b( hx40) and ht 60 with im guessing a 23 housing i have only really been able to get 40lbs boost.. im guessing its because i never changed the wastegate setting. how do i change it? lenghten the rod or shorten it? if thats not the problem any other thoughts would be helpful
What is the pressure like between your two chargers? I am guessing that your top charger is making all the boost and the bottom isn't pushing much air through. You want the wastegate on the top charger to regulate it to a PR of roughly 2-2.4:1.

ok i put a guage to it and the big primary is pushing like 7 or 8 max and both are hitting 35... any ideas to help? i should have plenty of fuel, and i can tell they both spooling up i have tried 2 primarys as one was putting oil in the intake tube
and the second one idont know much on but the look similar

yea dont make much sense i think the oil leaker did more but i didnt get a pressure check on it b/c i didnt want oil everywere dont know what to do really ... i think im gonna go back to a single till i can afford a new ht60
Ambient pressure at your elevation is 14.01psi. So your primary is running at a PR of approx 1.5:1. And your secondary is running at a PR of approx. 2.22. The secondary probably right about where it wants to be, It could stand to go a little higher, but really you need to get that bottom charger spinning to get your airflow up. That super b probably could stand to run up to about 3.0 and similarly with the ht60 as larger turbos operate better at higher PR's. Anyways, I think that wastegating is probably about spot on, but you need more fuel to get that bottom charger spinning.
