Turbo BS Thread

That is specifically. However, it does not interfere with the the boost readings or sensor readings due to any pulsations from that solenoid being isolated. My front port behind the TB feeds a vacuum block. Which in turn feeds all necessary ancillaries.

All of your vacuum routings may be absolutely correct. It may just be turbulence across your MAF sensor.

 

The guy that helped me fab mine up has the boost

 

Well I thought having ~12" of straight pipe going to the maf would have reduce turbulence a good bit.
What are you saying now about routing the evap? Mine is probably ok?

 

That change in diameter right before the MAF, without a straightener, may contribute to MAF turbulence related issues. Seen it before. Been datalogged a lot on XRU.

You can try clocking MAF section in a few different positions and then see if the readings improve. Try to find the sweet spot.

 

Any thought on why an eBay JB turbo would be over oiling even with a restrictor? Slinging oil out the exhaust and dripping it out the compressor side... @MadTaco461 you have any insight?

 

Gonna try a bigger return line

 

I use an AN10. Your oil drain nice and free flow looking? And above the oil line?

 

Downpipe getting close. This smart guy bolted up all his flanges before welding.

 

Yeah its pretty clean. Its on that buggy... I think he said he had 1/4" and I was thinkin was 1/2" so we took several things apart tonight that were probably unnecessary Ha Ha. He had a 3AN nitrous hose for feed to begin with and in had a 4AN with a reducer so we put that on after we tore the turbo apart and couldnt see anything wrong but she was still blowing oil out and smoking like crazy... A bigger line is in order for sure

 

The right move.

 

Center cartridge was properly clocked?

If so, then it could be the orientation of the seals as well.

However, you said eBay as the brand name, so that alone could lend to a tolerance issue, if the larger drain hose doesn't fix it.

 

My eBay turbo had a 1mm restrictor. My feed was an4.

 

Dang... I didn't think you ran a restrictor with JB turbo... This one was pretty small just based on what welding wire looks in would say maybe .035... I think the return line will get it squared away hopefully

 

I wouldn’t go smaller. Good ol crap turbos at their finest.

 

Bigger return line in and all the oil is blown out of the pipes...

IC relocated

 

Haha that little thing looks fun

 

He said it was like 1700 lbs with him in it and it should be north of 250 hp soon

 

Going to be insanely fun!

 

So he has seen several guys push low boost on this little subie with no real updates and he says thats what he is gonna try. He got a wide band to monitor afrs andnhe said he is gonna keep it at or below 7 psi. I did suggest maybe looking into a 5th injector if the need for fuel arose, but I also got to thinking about the diesel guys that run propane... That would be added fuel plus when lp vaporized it is more than ice cold so if it was plumbed post IC it could make them intake temps well blow ambient while also adding fuel... Am I crazy for thinking this? If there isnt a set up really, like a small WG could be used with like a 1 lb spring so when boost came on the line was open right?
