Jakpro1 Dyno and Tuning
Lookey lookey what we found....
This is some scarey stuff, and we are just glad that JakPro's car didnt suffer any serious problems.. Compression check came out ok.. no bottom end damage.... CLOSE CALL!
I guess having a properly working S/C will resolve this problem.. New S/C is on the way... 15psi here we come..

Good news is that if it stayed in one piece then the intercooler would have caught it. If it splintered into lots of lots of pieces.....

Compression test is still good so not hyperventilating yet.

The last thing was to remove the VRP Gen 1 80mm TB inlet with the welded plate and put on the new 1 piece inlet.. as Vadim & George were tearing it apart, they did a once-over on the S/C and saw the chunk missing...
We are just glad that we went through the car and did find this because who knows how much worse it could have been in the future if this went undetected.
Hopefully this will give us the lost horsepower we were looking for.
Stay tuned...

Pretty sure we will never really know so just gotta move forward.
VADIM, nice find buddy! 1 great thing about takin you car to Vadim is he and george go threw the whole car checkin everything out. He found a loose brake line on my car when it was there.
I agree with Rflow,but just to be sure.Check the inside of the rubber Y-pipe that connects to the mouth of the TB.Look to see if you are missing one of the internal metal rings that are used to keep the rubber pipe from collapsing.It has been seen where they pop out of their recessed grooves.Its from squeezing the y-pipe hose when installing or removing the y-pipe.Though I doubt it would make it to the rear of the rotor with out exploding first,its still a thought.
I gotta Love your funny Comedic puns. It really lightens what could have been some serious pain. You know "root" canal after a tooth extraction.
We never did find the broekn piece, so what happened to it is still a mystery. There is no sign of any metal going through any of the cylinders, compression is good and fairly even accross. There is no damage to the intercooler.
I will use boroscope to look into the cylinders tomorrow, but I think we are OK.
Jim, shouldn't this have been noticed when you shipped the engine parts to VRP for Porting and HEads?
WOW.....What an unfortunate chain of events...........

That could only mean the piece was removed or fell out during the first TB install or head removal. Makes you wonder if the blower could have been dropped and something hit the rotor.
Jim, I hate to say this but I would bet that somewhere down the line someone who worked on your car knows about the missing piece jmo.

Man, you were closer to the 5.7L than you thought!!

F-In Props goes out to Vadim & George!!
