Turbo BS Thread

That routes across over to the EVAP stuff. I believe its the EVAP purge line back to the gas tank, and I put in a check valve at the cross in the below, with air flow allowed <<<





Thinking more on it, am I possibly introducing PSI into the crank with how I have the PCV and Vent T'd together?

Also, is the IAC vacuum tube ok to see boost? It routes back down to the top of the engine.

 

Yea I tried to find a Y but no luck yet.

 

Everything looks fine. Like Tor said, try to get a Y for better flow.

 

Another question I had was regarding the FPR reference, should it be a dedicated line or is it ok to be T'd in with something else. Asking, due to that weird AFR issue I was having the other day where it would stay around 14 while boosted until I got into higher RPMs it shifted to the next gear before it would drop to 12.5. Its only random once in a while though...

 

Iac line can have a check valve. Mine does left over from SC days. Either way it won't pressurize case. Just re seal the pan probably. You might try to up the line size after the Y (T) so it has enough flow to support both the incoming lines. I had to weld up my own Y.

 

It's fine to be tee'd in with other things, maybe not too many other things though

 

Dedicated is perfered.

 

Yea, I still have some of that 5/8 tubing left over from the oil drain fiasco that I was thinking to rig something up. Good to hear on the IAC, ill leave it as is for now. I still need to go test drive it today and see if tightening up made any difference, but re sealing is on the list here soon again.

Thanks!

 

There is actually a port super low down on the runners just for it I think

 

Currently only Tee'd in with the BOV. I was going to play around with it dedicated to see if that resolved the AFR weirdness... that or its still in closed loop for some reason even though I am pedal to the floor.

 

I think that port is gone on the later model Speedy. He could drill and tap the manifold to 1/8npt and put a barb fitting in if needed.

Honestly it's probably still in closed loop. I think the vac line is negligible as is, but dedicated definitely won't hurt.

 

More reasons to get that enricher wired up... ive been slacking on that

 

There's a 7th kit for sale with fuel pump in classifieds.

 

I just pulled one off of a truck that went to Haltech as well. @drr you might have folks in here that want your 7th kit.

 

Any of you guys live in/near Pensacola, FL?

 

I have found new uses for turbos besides making trucks go fast. Like helping set your new sink in the caulking.

 

Yep, got a full URD 7th kit tuned by Gadget, just need to pull the fuel line off this week and it’s ready to go. If anyone is interested, let me know. I’ll make a BST thread in a few days.

Also have PLX modules for boost and AFR with Bosch LSU 4.9 sensor for sale as well.

 

Not I.

 

One more down. More to make.

 

Open T4 or divided?
