@@holdinator9855 the compressor efficiency map stops at 33 psi on the HY35. You're better off buying a new Borg Warner S362 turbo, and an adjustable wastegate actuator, to net 40 psi.
All I did was crush the vacuum boost line with some vise grips. About a 30 sec job and cost nothing (If you have a pair of vise grips). Works well too.
I have to put a new wastegate on my 01 automatic and I'm just trying to put it at stock psi does anyone know the adjustment to just get stock measurement?
If it's just the stock hy35 you're looking at around 20-21 psi on average unless you really get into it then it may jump a little higher. If you slap a turnbuckle on the hy35 you could see numbers up around 30 or just over. Hx35 turbos are about the same unless you add an adjustable boost elbow then you can get up pushing around 35ish safely for that turbo.
Bruh. I can’t find an hx anywhere. I have an 01 automatic. And my waste gates stuck open. But as you know. You can’t swap them. So I’m about to but another hy cause i can’t find an hx
I searched Craigslist and lucked out and found one on my first search. Have you thought about just ordering a modified hx35 from turbo lab of America? Its not gonna cost much more and you'll get a 63mm compressor wheel and 67mm turbine. Better performance all around for a few hundred bucks more. Comes to your door freshly rebuilt and ready to party! I'd look into that man!
Help! I rebuilt my hy35. Getting a a different whistle out of it now. Had a tough time pressing (pounding) the exhaust side back on. I read gaps/cracks could cause whistles? Any insight?
Yeah, you shouldnt have to pound anything back together. It should all go back together fairly easily, like it came apart. Did you check everything over really well to make sure there is no cracks in exhaust housing or anywhere else?
@@purepanorama8484 I'm guessing it's because I freed up the waste gate while I was in there. I took my camper up in the hills this weekend and realized it's not so much a whistle but a change in tone. The exhaust housing was a b$%&* like in your hx35 exhaust housing removal vid so I didn't think twice when it was a pain getting it back on. Thanks for the reply and thanks for all the work you put into your vids. I'm a Cummins newb so it's very appreciated!
@@g__wizz The slight gap is what worried me. Before I did the rebuild it seemed there was no gap. I was using a rubber mallet but I probably didn't clean the mating surfaces well enough.... thx
