Hey guys,

 

I have 50 hp injectors and the quad installed but not wire tapped because the transmission has not been upgraded yet.

I've been running the quad on level 2 most of the time with occasional level 3.

 

I have never seen the boost on the quadzilla app go above 22 psi and am showing 1 psi at 55 mph.  I did a leak check and found a couple of small leaks at the lower boots which i tightened.

Seat of the pants says the truck is putting out more power but the MAP reading seems low to me.  I do not have a boost gage on the truck to compare with the quadzilla reading.

 

My question:

Is the boost readings that I am getting for my current setup low or is this about right?

If this is a low reading and assuming I have taken care of the the leaks where else should I look for the problem?

 

Thanks

Do you have a boost elbow in the HX35?

Yes I have an adjustable boost elbow installed and it was supposed to be preset to open the waste gate at 30 psi.

 

I could try adjusting the boost elbow or just clamping the line as a quick check.

I'd just screw it all the way in. You might consider checking the turbo for play / rubbing as well. 

Ok, I'll do both this weekend. Thanks

I turned in the adjusting screw on the boost elbow and am now getting 31 psi. 

 

I realize that the boost elbow is basically a metered air leak and that it was supposed to be set to 30 psi when purchased but who knows what conditions were used to determine the initial setting.

 

There is some play in the turbo and I am seeing a little oil film but it is not rubbing yet.  Looks like I better be think about doing a rebuild in the near future.

 

Thanks again.
