boost leak

[tylerearl88]

took my diy turbo 08 nytro for a rip across the lawn for the first time tonight. It idles good and motor seams to be running well but when you start to get into the throttle it sputters, boost gauge will not read above 0 and the air fuel is at 10. I think it is a boost leak. What would be the best way to find the leak if it is not an obviouse one like a line off? also does anyone have any idea what else it could be?



thanks.

I built it myself using a mitsubishi 16t turbo.

Build a deal to run air perssure into the turbo. I did it with a left over silicone hose the size of my turbo intake and a PVC plug the same size with a air chuck in it. It sounded like a den of snakes under the tunnel. (rear mount) makes it real easy to find the leaks.

Found the problem.blow off valve diaphram was weather cracked. Is there a way to adjust the idle. It will not idle now also idles rich.I can get it to 6-7 lbs of boost but it's a dog and only revs 7000-7500 rpm. There is only about three inches of snow here and no traction but even slowly accelerating on a long stretch it only hits 6-7 lbs and is only reving 7000-7500 rpm at 120km per hour. I have super tip weights and a helix from ulmer and a pink primary spring from ulmer. Are the weights to heavy???

What is the best way to test for leaks? Can I seal off the air intake and pressurize it at that location or should pressurizing the compressor of the turbo be avoided?
