I put a turnbucle on my turbo and i am getting 42 psi out of it...it is a HY35. Is there anyway of building a boost control without spending the 130 CDN?? I am scared too get on it for fear of it grenading. The EGT's are the same as if i were running 18.....but 32 or 33 would be nice too keep (FOR NOW )

Thanks for any help

 

Can't you just loosen the turnbuckle so thats its not holding the gate closed completely?

 

Get a shorter turnbuckle and an assortment of short stiff springs. Hook it up the same way.

 

loosening it will only make it fall off,,not the plan.assortments of springs ive tried,,with no luck also..this sounds strange,but works..i pulled the hardline out of the compressor housing and ran a screw up in it to be a restrictor,,then i tapped a hole in the hardline right in front of the actuator with a saddle valve,,sneak up on the bleed off hole size,as you get bigger,itll open later and later in boost.mine will peak at about 36 to 38 lbs. as it is right now.that was the coolest i could get it with mine.i tried from 25 up to that point,,and that was the coolest.....bama

 

after posting that and reading it,,it could be made a little clearer i guess ,,i ran a headless screw up in the end of the hardline itself from the compressor end.the boost will run the threads up the screw into the hardline.the idea came from looking at a boost elbow off a regular turbo.it had a bleed off hole made in it which was adjustable with a allen screw in it....hope this helps,bama

 

OR you could just use an inexpensive adjustable boost controller that goes right in line and can be easily removed (if desired) later.

After you see one, you'll wonder why you ever messed with the turnbuckle.

 

The HY35 is pretty small, tho. I've read that the 32-35 psi range is actually just heating the air charge more from friction, since the turbo is so far out of its design curve. I'm sure I read a thread here about which turbo to go to for your desired boost levels, with plenty of room for future mods. $$ tho, so try the springs or restrictor screw methods first if more practical. I sure hope these values in the hair-covered computer are accurate

 

Adjustable system is only way to go...than play with it to see what boost controls your EGT's best in your truck.
When I had EZ, DD3's & HY-35 I felt 35-36 psi was where I started to superheat the air to the engine...power curve seemed to flatten out dramatically above that level. Bama found it's at 36-38 for his truck, based on EGT's. I suspect all HY-35's are not exactly the same and different mods may make a difference also.

Do what you have to, to keep boost at 38 psi or less...you turbo will thank you with much longer life and better performance.

thanks for the feed back everyone....i have drawn up some blueprints for an adjustable system. Hopefully it works well, and then i will post them.
