turbo boost preasure?
#16
Ok guys thanks for all our help still confused though.
just came back from and 1800 mile trip with our 14000lb 5th wheel with very large hills 7% grade. Truck ran good had good power at higher rpm lots of smoke must have been making some boost as i had the propane on and it use 23 gal going up but very little on the way back?
What is EBPV ?
Thanks

You can run 1200 all day long. Don't be afraid to Rev it up to 3000. If turbo not spooling then maybe you have a leak in up pipes. A leaf blower to exhaust and some soapy water can find leaks.

Found the problem no turbo boost 1 psi at 3000 rpm
took it to my mechanic he says turbo is dead. he took off intake and manifold tubes says end play is good spins free but produces no boost? waste gate working and closed. didn't have time to look at exhaust impeller but thinks that is where problem is. I needed truck back as we are leaving on vacation. going to put a stock turbo back on. any thoughts and suggestions appreciated.HB

X2 I had a guy yesterday tell me that our trucks had a wastegate (ebpv) and that I needed to be careful deleting it as it could cause my turbo to spin too fast and blow out the tailpipe... lol

I have seen exhaust wheels desintegrated before...some by heavy fuel tunes, and big manifold pressure leaks. Literally melting the fins away, propane also assists this process.
That all being said your mechanic is a moron...1. for saying there is a waste gate. 2. for putting propane on the truck. I would take it off immediately or go buy a new motor here real soon. modern day diesel tuning has proven propane an old and poor power making method. Nitrous would actually be a better choice... The best is a chip and just sticking with diesel... nitrous and propane both change engine timing, flashpoint, and cylinder pressures.... good luck..
If you are blowing a ton of black smoke at high rpm you have bigger issues, likely boost leaks, vlown turbo, dirty air filter...
I'm willing to bet that pyrometer is in the down pipe isn't it....
18k is no joke for a 7.3 to pull.... even more so if the motor is not fueling/cooling/running properly

Ok guys I appreciate or comments and help
Today i installed a boost gauge. My ETG is 2 inches from the turbo in the down pipe. running in drive way no boost. just the truck going down the road getting on it 17 psi ? I know someone said that it would not make boost if no load? Now what?
took the y pipe off to tap for boost line
