Turbo Troubles.

[the baPhoon]

Whats up folks? Im the new owner of 93 Typhoon #24. Yes this is my first ty so bare with me. I purchased the truck a week ago with 78000 original miles and its in pretty tits condition. My problem is i believe the turbo isnt making the proper boost number, If it is my boost gauge (stock) is off by about 7psi at any givin time showing a max of about 7 under full excelleration. I did check the buyers guide and followed the instructions there before buying the truck from a dealer in Socal, and i did do the breakstand to check for PSI and made the requiered 5+ but didnt notice the lack in boost while driving untill i made it back to Phx. (still its a nice truck and im FAR from complaining). Ive had a friend tell me it could perhapse be a wastegate problem or a problem with the turbo itself. I can feel boost under full exelleration but it does feel a little lacking (but this IS my first phoon so you cant trust my judgement.) My friend, a mechanic, has drivin sy's before and also thinks the boost to be a bit off from what he remembers. I dont have any 0-60 times or QM times as of yet because i dont want to push it too much if the turbo is takin a dump on me. Any info is appriciated.

:werd:
While at 15 on the Autometer, my stock guage was about 2/3. Get an el cheapo boost gauge and plumb it up to the plenum and see what you read. Withouth knowing exactly what its reading, A) you shouldn't adjust anything, and B) we cannot give many suggestions....

Re: Turbo Troubles.

also... what chip is in your truck.. if you have an aftermarket chip that runs off of a 3bar map sensor instead of the gay 2bar stock map sensor then your stock boost gauge in your dash cluster will be way behind what the real psi is.. and as mentioned earlier.. the stock boost gauge is a waste of time even on a bone stock truck.

Here's a write up on installing an aftermarket boost gauge among other things

Re: Turbo Troubles.

The truck is all stock except for a K&N stuffed on the end of the stuck air puller. No chip as of yet (yes i am indeed a brokeass). Gona go ahead and get a boost gauge from auto zone for now, i can waste the 40 bucks on the ugly thing for diagnostics and get the one i want later on. Ill get the gauge and post back asap.. thanks for the help fellas.

Fire me off an email man.... adkidder@us.ibm.com

I have an UGLY boost gauge that I'm not using right now I can send you to use. I know what you mean with being broke; use it for diagnosis and send it back to me when you're done.

Re: Turbo Troubles.

Check the boost control solenoid.If it's unhooked,the truck will only make 8 psi.

The boost control solenoid is about the size of a 9volt battery with 2 vacuum lines hooked up to it located right above the turbo. The 90 degree boots are probably broke from age and heat.

Also the stock chip will only give you half boost (7-8psi) on your first WOT run for safety

Re: Turbo Troubles.

Yeah i read about the boost flag and that doesnt seem to be the thing.. i can run the phoon for a few hours under light boost and when i get on it she still only makes about half. The vaccume fittings seem in good condition. Would a vac leak in the line cause the gate to not fully open? if all else fails ill just see if i can waranty the shiznite.

Re: Turbo Troubles.

Allright, upon further inspection i found a bit of oil leaking out of the bottom fitting on the right side of the box. Theres no line running to this fitting as the pictures show.

The vac line in the picture i yanked from the top fitting for a clear shot of the bottom.

Re: Turbo Troubles.

The bottom port has nothing attached to it.It came with a little foam filter there new.

....and the residual oil is nothing to worry about; just what's coming out of the compressor housing. If you pull the air intake tube out of the orange elbow, you'll see oil as well.

Re: Turbo Troubles.

Im also getting a nice cloud of smoke from the exhaust when i start it up. Hot or cold it does it only on startup and the only thing i can think of is water in the dino juice.

Valve seals, its pretty normal problem for these truck and more of an annoyance.

Re: Turbo Troubles.

Valve seals ehh? that puts my mind at ease lol. Now all thats left is troubleshooting the turbo and ill be in buisness. heh it might even be my imagination and the gauge is off by 8ish PSI. I might have a new boost gauge on monday so ill be able to shed a little more light on the subject.

Right on, there will be quite a few trucks there. 3 Ty's including yours, a Syclone and a SoGT. Pavilions is at Indian Bend and the 101 in the McDonald's parking lot. I would say if you're on Elliot....take I-10 east to 202 east to 101 north to Indian Bend.

If your turbo is only making 7 or 8 lbs of boost, then your wastegate solenoid might be hooked up incorrectly. Typically when you have the solenoid unplugged, it will default to around 8 -10 psi on most trucks.

Re: Turbo Troubles.

Allright as per your advice PPi i undid the vac line on the controler solenoid and as was thought i made the full boost. so.. now what? lol

Re: Turbo Troubles.

Allright i heard back from the previous owner who wasnt having the same problem but i did get a nice story that might be some background on the problem at hand.

little story it was a nice cool nignt like 10 pm i take my son
for a little ride . i stage the truck. i hit the gas . it takes off like never before 15+psi im flying im thanking wow i look at my son
he's like wow . it hit's 2 nd still flying .. 3 rd too fast need to stop for stop sign ahead i do at the sign i look at the dash to see
every red / yellow light on i drove it home to find every vacuum line had blown off . thats why all the lines are new.
