Ahhh MAN..... That really sucks!!!

 

Holy *** crunch that sucks!! . Your truck was one of my favorites on this site!!
What is it with some of the high horsepower trucks burning to the ground? This is the third one in the last three years!!
Got any pictures of the truck? How bad is it? Anything salvageable??

 

dang just read through this whole thread! Was really looking foward to see some numbers especially since you changed to that pt88! Sorry about the truck man hope you get it rebuilt soon!

 

Ahh, thats kinda scary..

x2 on how bad is it. Any idea on the cause?

 

dude sorry. guys who are putting down alot of HP, double check all your junk! What was that other post about the fuel pump wires melting...glad no one was hurt.

 

sorry to hear this... can u post any pictures????

 

If I had to guess since I had 20,000 miles on it being supercharged, the only thing that had been changed electrically was the addition of the sts pump for returning the oil. I didnt wire it myself but I know it was on all the time and I assume he didnt fuse it. I see in your thread you had said the sts kit had a checkball or something in the feed line and after sitting it would leak oil into the turbo, I had the same issue but never got to the bottom of it so let me know what the fix is. Thanks, Mason

 

That sucks man! Im assuming its salvageable by the way you said so you know its time to build it back better than ever!

 

Yeah, you gotta fuse that pump

The check valve was definitely the fix. Just enough seat pressure on that valve to keep oil from draining after the engine is turned off. But yours is a front mount, right? You shouldn't have that problem with the turbo being so high up... Maybe a little drainage from whatever oil is left running downhill in the line, but not enough to really cause an issue, especially with a gravity return line.

 

I want to bring this thread back from the dead because I have been slowly working on a side project that could make compound boost a very feasible reality. My Cutlass has a MP112 and I love the low end but the top side leaves a ton to be desired, so I started looking into compound boost and saw the issues with uncontrollable boost.

I am an electronics engineering tech and I work for one of the largest national suppliers of anything heavy duty diesel you may need and I have access to a wide variety of interesting things. Borg Warner has a line of variable geometry turbos that currently WILL NOT work in gas engine applications because the hot side, the side with the variable vane inducer is not rated to gasoline exhaust gas temps....BUT hopefully they will be resolving this eventually.

My engineering department is all gear heads. We have already designed a standalone controller that is fully programmable to drive the VGT turbo. The system is not built or tested or anything like that because of the lack of a suitable turbo. BUT if B-W ever releases a higher temp range VGT I will have one and this system will be built and fielded. The controller will use TPS, RPM, MAP, and trans gear (automatic) to reference a table, programed by the end user, to regulate turbo output by varying the turbine inducer.

Example: In a compound application, on a WOT accel from a stop the blower will generate say 5psi instantly, now say the first gear table @ WOT in the turbo controller says you want 10psi in first gear, the VGT will pitch the inducer to make 10psi MAP and maintain until 2nd gear. In 2nd you want 15psi, again, VGT controller see's 10psi MAP after the shift, it commands the VGT to pitch the inducer to make more boost until 15psi MAP is referenced then regulated by the controler. on to third.... same principle.

Until B-W makes that turbo, which should be on a S400/475 cartridge, its all an idea. When/if they do, be ready for a BIG thread
