well today i put in the 3200 spring and POD's and a HX40 turbo on my 92 W250. before with just the full power screw turned to almost runaway and a custome fuel pin i would run 29psi boost and now it only hits 25psi. and i lost power butsmokes like a siv. any ideas

 

Did you get the throttle lever clocked right?

Got a boost leak maybe? Check between the compressor and the elbow, that O-ring goes flat and doesn't seal after a while.

 

this is a different truck than the one in your sig right?

 

well the throttle lever is clocked right. i will look for boost leaks. and i will check the o-ring and see wat i can come up with. thanks wana

 

ya different truck.

 

Correct me if I'm wrong, but Boost pressure is a measure of restriction, and you may be running more air VOLUME, rather than air restriction with your bigger turbo. Does that make any sense?

 

umm not really. not really sure. but there is a noticeable loss of power.

 

Is there a wastegate on the new turbo only letting you hit 25psi? Just guessing.

Air cleaner?

 

rollincoal23 is your turbo in good shape? You made alot of changes at once and everything you did to a stock 92 should have made it alot better. Double check your thottle index and all your turbo hump hoses. Pods do smoke alot but i'm guessing the way you said it was smoking you have an air problem. Throttle index, turbo, hump hoses, air filter, i/c, l/p fuel pressure, timing, and waste gate. Sounds like the guys covered the obvious. Your probably just overlooking something simple. Good luck with it and keep us posted.

 

thanks for the help fellas

 

Well to try to answer your question. Boost pressure is that. What the turbo is making. Even if the turbo is bigger at the same PSI, the larger turbo is moving more cooler air. I can see were your going with the question though.

 

if i remember correctly, days of our lives is on at 1:00, hell its only 11:32, you guys got started early

Back to the original question, rollincoal23, did you get your noticable power difference back or is it still acting up, you said thanks but never gave a conclution. seriously curious as to what happened

 

hey benjanin b2. that must be one of your favorite shows,seein as you know just when it starts. haha!!!!



but anyhow. no i havent figured out wat the problem is. i have pulled the intercooler tubez,and hoses. checked everywhere for boost leaks and got nothing. im seriously stumped. but i did notice that if i turn in the full power screw nothing happens anymore. it just stays the same.

 

that is not a good sign, ive broke a the full load lever off and its quite costly, that kinda sounds like what it is, did you screw it in to far or not screw the power screw back out when you took the top off, if you break it off, and you reindex the throttle shaft, it will run but will be realy weak, i know mine would get to 55 but it would have the petal to the floor and it felt like it was lackin on boost and all sorts of power, what all did you do to the inside of the pump?
