I installed an adjustable boost elbow today preset at 30psi.  Before the elbow with the Comp on 5x5 I was seeing a moderate amount of smoke at wot.  After the elbow installation it's rollin' some serious coal now at wot. Am I mistaken thinking that there should be less smoke with the elbow than without? Truck runs awesome just curious about the smoke I think I choked a poor guy on a bicycle today when I passed him.

Ok did a little testing on the way home from work. Rolling down the highway at 60mph if I floor it I get 30psi 1100 EGT at 2800 rpm. At a dead stop if I floor it I get 28 psi 1100 EGT at 2600 rpm. This is all with wastegate plugged.

You got to hold constant air to the system. Just like my video I hook up a regulated air hose to the system and leave it hooked up. Not like inflating a tire and expecting to hold air. There is all kinds of natural air leaks like past the rings so it will never hold air. That why you hook up to a constant air source.

Sounds like to me you aren't getting enough fuel either. If you only had a boost leak you would have higher egts

I'm an idiot Mike.  You're absolutely right.  It never even occurred to me until I read the words on the screen. Thanks, time to start over.

Maybe that's just all I can get from the stock injectors?

Stock injectors should do about 28-30 PSI typically. I use to just tip in at 32 PSI.

So I am pretty well where I am supposed to be. Can you run 50hp or 60hp injectors with 35psi boost safely with the stock head bolts?

+50HP injector in my truck plus Edge Comp on 5x3 bury the the boost gauge at 35 PSI. No issues here.

Thanks. And thanks for this site.  It's an invaluable resource.

Huh, yea, running 75 DAP sticks, Comp on 5x5. Hit 35psi momentary and 30 constant. Have to watch EGT's...

With my set up if I stand on it I can hold 35psi till I have to pull my foot out of it (EGT's ). On stock sticks with out an Edge Comp just on the Smarty I could only hit about 28-30psi and maintain. For your set up I thing your probably good.

Yeah you're right on the money.  I went low tech and just put a wrench on every clamp and then re-torqued the intake bolts and that took care of the problem. Probably had several leaks but it's good now. I'm getting 28-30psi and it maintains a lot better.

Definitely not trying to hijack anyones thread, but i have a question closely related. I have the hx35 on my truck with an afe wastegate actuator set to 38ish, and my edge jwa is set to 40 but when i wot i can only get around 25psi of boost. does this mean i have a leak?? or is there another reason??

Most likely you have a boost leak. The only other explanation would be lack of fuel to spool the turbo. What are your egts

I agree with TFaoro if you have high EGT's then you have a boost leak. If your EGT's are running low then there may not be a leak you may not have enough fuel to push it that high. I would also check your MAP sensor and make sure the edge is hooked in so you get the boost fooling. With out it you can have a defueling issue going on. 

 

On the HX35 don't push it past 35psi or you will be out of the mapping.

When my MAP sensor came unhooked it didn't feel like it fueled at all. I could be wrong, but I don't think it will fuel at all with a bad connection.

If it comes undone it should throw a CEL but if its just loose it could cause defueling or other problems.

Good call!

I dont drive my truck during the week so ill definitely check it out today, but i dont think my egt's have ever gotten that high, what should be average? Ill check on the MAP connections here in a few to, thanks guys

Ok im back with some drive results... cruising at 65 my egts according to edge jwa was 700 ish if i got on it they jumped to 1050ish but then dropped right back down as soon as I let off it. When i got to a red light they would drop down into the 450 range depending on how long I was sitting.
