Twin Turbo Build Progress -pics-

T T T

this is one of the most ballsy projects ive ever seen done on a mustang, and i wanna see it done and running well

 

[MysteryMachine]

Beings he hasn't posted. I talked to him the other day. By the way i took it all the piping is done but the MAF he bought was wrong so he called Blueovalperformance to find out about getting another one.

So it should be soon guys

Damn... and I thought I was handy for making my own CAI. lol

Thanks guys, sorry i havent posted pics. My mother went to FL and took the camera i was using. But when she gets back this weekend i wil update.

For progress: The car is completed except for....I needed a pigtail for my new MASS air, and i recieved that today.

All i have left to do now is hookup my wastegate and BOV vac lines when i recieve my MBC, Put my wheelwhell liners back in, and install my CC plates that i have been putting off.

Them, its off to the dyno for a custom chip-reburn.

Im trying to decide the safest way to drive it up there.....also i am pondering driving it a bit before i go, just to make sure everything is working ok. I have the 42lb injectors, and a Calibrated Custom MAF for it. I was thinking of locking out the timing at like 10 deg? anyhow, its damn close now. Btw the air filters look badass in the side scoops!

i would prolly run less than 10degrees.... just to make absolutely sure....that, or if you can adjust you wastegate(change spring( put a lower pressure spring in, or dial it down so it won't build as much boost....

If your going to lock it out, you could prob. go alittle higher at say 16-18*. Just pull the spout and put it in the glove box. I may be totaly wrong on this as I have very little boost hands on exp.

THAT IS ONE SICK PROJECT

why not just run it n/a til you get it up there?

 

[walker95svt]

This build is incredible........ I originally wanted twin turbos, but it would be biting off way more than I could chew financially and at the time, in experience. I can't wait for more pictures. This guy gives me hope for my tan interior that I hate.

ok guys this car is REALLY close to being done, i got the system complete and fired up the car....of course it runs like crap, it still needs a tune. Anyway, question, what do i need for one way vac hose fittings? Meaning what areas do i not want boost to reach? I know i should get some sort of vacume diode....but what do i need? Also, is it ok for boost to get to the fuel pressure regulator?

Basically, What do i need to isolate off that dosent want to see boost? thanks guys. This is the last peice of the puzzle.

I remember seeing a turbo setup on Big Jay's stang (even though his mag feature had a s/c...?). Anyway, maybe if he chimes in or you pm him, maybe he can give you some guidance. Lets not forget Oink...the turbo guru himself If anyone would know, he should.

 

[nito88stang]

you dont want boost gettin into the pcv.

 

[OrangeMustangGt]

ok, my question is the FPR?

 

[Don 95Vert]

The FPR NEEDS to see boost - very important - in fact I'd run an isolated line to the FPR. It won't hurt for the brake booster to see boost - they have a built in one way valve. I run a one way valve on mine for the interior heater controls - just a generic brake booster valve. Th ePCV is a problem - it was for me anyway. I tried an Incon one way valve and it still blew the dipstick out. We ended up gutting a PCV valve and blocking the vacuum to it and running an open line to atmosphere with a oil seperator. If you do this you need to run vented valve covers too.

 

[BlackVert]

ok, my question is the FPR?

I don't think you need to isolate the FPR, not sure tho. I don't remember reading anything about needing to isolate the FPR on turbomustangs.com. As vacuum decreases, fuel pressure increases, so boost should result in the highest pressure it is capable of, which is probably what you want.

But, I'd post a question there in the tech section to be sure if I were you.

Let us know the answer, OK?

[Don 95Vert]

Just sharing something I found out after tuning many, many turbo and SC cars - with a seperate line to the FPR, you get instant response to vacuum/boost changes. Sometimes if the FPR line is shared with HVAC lines - fuel pressure may drop - seen it on a few cars. Use the info or not...

And yes, the FPR needs to see boost - you need a 1:1 increase in FP in relation to boos because the injectors are firing into a pressurized environment and you need to compensate for that.

On my car I hardlined all the vacuum lines and used clamps on them to keep them from blowing off under boost. If the FPR blows off during a run, you probably could not get out of it quick enough to save the motor.

Cauf Cauf need more to feed off of plz more photos :worship:

 

[OinkAodeOink]

Listen to Don95Vert.. he knows


I managed to yank a PVC one way check valve off a turbo coupe at the junkyard.. worked fine. Yes, have a lone vacuum line running to the FPR, clamped tight, or zip tied.

 

[OrangeMustangGt]

Whell i finally got the car off jackstands and was driveing it around carefully. I wasent making boost really, just checking drivability with the new 42's and the new blow through MAF....it idles like crap but drives damn good.....good enough to get me to the tuner i think. When the car is on the ground, that oil line is damn low to the ground, i may try to invent a new system where i can run the line up over the exhaust pipes instead of under. As far as the sound...wow i am soo amazed, it sounds great, and the bit of spooling sounds badass!

A couple questions....the most i got the car to was ~5 psi, and when i let off, it made a Psst Psst Psst sound from left to right.....am i correct in saying this is compressor surge? I have a BOV connected, but its one of those "universal" ones, and i think it may only go as low as 10 psi.....what should i do, or is it ok? thanks

 

[DARK-5.0]

Sounds like a bit of compressor surge to me too. But with only 5psi, it shouldn't be strong. But I'd get a quality bov instead of some universal one off ebay or something.
