Installed my boost gauge over the weekend using a tapped bolt. At WOT i'm seeing 16.5, maybe 17 lbs of boost, I believe my '99 auto should be set to 18 from the factory, correct? Should I be concerned about my missing pound of boost? <br><br>I would guess that I might have a slight leak in my plumbing somewhere. I put thread tape on all the joints except the tapped bolt itself, where it screws into the intake manifold. Is this a problem? <br><br>One more thing, I think I have an HY35 turbo, not HX35, is this correct?<br><br>thanks-

 

I had to get the RPM up, along with WOT to get to 19 with mine. Even with my boost ellbow in there if I turn my box off I get 19 lbs of boost because I wasn't getting enough fuel to make it go higher. I have not tried blocking the boost elbow yet. :<br><br>Your 99 should have an HX-35. Mine does. BE glad you don't have the HY.<br><br>Chris

 

What's wrong with the HY? Almost instant spoolup. I push 30 psi out of mine whether Comp is on or off. I used to push 35 but I backed it off cause I didn't need that much boost. A year later and god only knows how many barkings, it is still in perfect shape. No shaft play or anything. Now. With that said. I wouldn't worry bout that one psi. I hit 22 psi dead stock on my truck (used to be around 17-19 though). And no overboost code either. Oh well.

 

The little tag on the compressor side of the turbo will tell you the type and size of the outlet.

 

Blue, I am hopefully putting on my gauges this week (if they show up). I have the EZ and want to up the boost on the HY a little. What are you doing? Turnbuckle or Turbo-Master? Something else? Pros/cons?<br><br>Thanks

 

I'm just using a turnbuckle. Mine is set loose so I don't push to much boost. I used to push mine to 35-38 with no problem (and I rag the crap out of my truck). If I had to do it again, I'd get the turbo master. But it wasn't out when I went to do mine. Besides, the turn buckle is cheap and easy.

 

I get 17-18 lbs stock. I am getting a ez this week and wanted to know where to put the turnbuckle. (obviosly on the waste actuater but, what size buckle, open ends or closed, what length at lowes or home depot???) anybody know????

 

Thanks for the responses everybody. The truck seems to run great so I won't worry about the 1 psi. <br><br>As for the HY vs. HX, I was under the impression that all autos (at least 2nd gen 24V) got the HY, but apparently I am mistaken. So what is the determining factor as to which truck(s) have HY's and which have HX's? [undecided]<br><br>It is quite possible that I just have all my info mixed up. I read so much on this site and elsewhere, that it's hard to keep everything straight. <br><br>

 

whats the deal w/ the turn-buckle thing?? how does it work, what's it do, what will i blow up...etc,,,

 

Im running almost 30 with the box off and 40 with the box on. have an elbol with the hose clamp off. Wes

 

Just got my boost/egt from Geno's on last night and am at 19psi. Will put the turnbuckle on tonight probably. Here is the turnbuckle picture off of the EDGE site.

 

I have the Edge EZ and the boost elbow from edge products and was told I should see about 27, yet the most I have gotten so far is 24 ??? Is there something else I can do to increase a little? I have the NV4500 so turnbuckle isnt necessary (so I am told)

 

Up the fuel. ;D If you are able to use the boost elbow, then you don't need the turnbuckle. Call Edge if you want. They may send you a new fitting. Check for any leaks on the rubber clamps leading from the turbo to the intercooler and back out.

 

Yeah I have been trying to get my hands on a fuel pressure guage to check it and cant seem to find one locally....so I am probably gonna have to order one off the net. Any recomendations on where to get a basic mechanical one for under hood testing?

 

The Briarhopper fuel guage can be had at BlackMountainDiesel.<br><br>Here's a link.<br><br>http://www.blackmountaindiesel.com/c...#pressuregauge<br><br>I think RipRook makes one as well, <br><br>http://www.protintnw.com/sa-main.htm<br><br><br>phox
