[Typhoon #2131]

Hello my new friends,
My name is Denny I have a 93 all white Typhoon#2131 and we are from Oregon.
I'm not new to the Typhoon but this is my first ever forum site so bare with me. I just got my Typhoon back on the road again 3 weeks ago after sitting in my garage for 11 years with no motor. It is mostly stock build except being bored 30 over with JE pistons and some light porting to the heads and 2 sizes bigger on the injectors. As with any motor rebuild there are a few bugs to work out and I'm not real good with turbo motors. I can build a 4.3l carb motor to run hard as I have one in a 1980 Dodge D-50 pickup running 11:77 @ 113mph in the 1/4. The Typhoon best time 11 years ago was a 13:50 and now I doubt it will get out of the 15's.

1st problem is I have one hell of a cold start problem. When it sits in the garage for a couple days sometimes it takes 2 or 3 tries to get it going and sometime it will start after a long first cranking try. Then there are times I'm lucky to get it going before the bat. dies. When this happens it will crank and crank and crank I let off and hit it again and it tries to start for a second and then back to cranking let off hit it again same thing ect. ect. any ideas?

2nd. When I get on it hard and the RPM'S get around 3500 the tack starts jumping till it gets to about 4000 and during this time the motor starts laying over. Help?

3rd. The turbo seams to go up in boost and fall in boost even when I'm in it all the way and also showing boost to only about 10lbs.

Sorry for the long post guys I will get better at this I promise . Any help I can get would be very thankful and I look forward to talking and getting to know you all. I will post pictures of my typhoon as soon as I can figure out how.

Are there any TY/SY car clubs in Oregon?

Thanks,
Denny

2 sizes bigger on the injectors? Can you clarify?

What chip you running?

Boost cutting is prolly from spark retard.The ECM is trying to keep it from blowing up.


Do not go WOT again until this is sorted out.It might go BOOM.

NWSTP.com is the northwest area members.

I have the same questions as jimmy, assuming the motor is mechanically alright I suspect you have a very mismatched combination of parts you have thrown on.

There are so many injectors claiming 2 sizes up tells us nothing except you probably made yourself a big headache.

Re: New member from Oregon

Thanks for the reply. Its kinda hard to read the guys writing but from what I can get out of it they are MPI 32s. I didn't build the motor I had a guy that builds alot of race motors here build it and had another guy that I race with put it in. I'm not sure what plugs he put in it and I know the wires are cheap 7mm.

The injector are MPI 32s. I have the stock chip in it. Spark retard? So you saying I need to advance the timming? It is at 2deg. advanced now.

Re: New member from Oregon

32's, I would assume might be 32#, which is stock size. Problem though is injectors of the same size/different brands don't flow the same.

2 deg advance? How are you setting the timing?

You should be unplugging a brown wire under dash, then setting it to ZERO, the computer does the advance from there.

Re: New member from Oregon

We did set it with the brown wire unplugged. So you think I have to much timing in it? So they came stock with 32#? That really chaps my hide. I told they guy I wanted to go bigger because the reason it blew up in the first place is because it leaned out #5 and burned the piston. I might be giving him a call.

What brand injector is good?

Re: New member from Oregon

You can't just throw bigger injectors in it with a stock chip. Your making your life difficult.

It can be lean or rich and its NOT the injectors fault. #5 is common to be the leanest of them, but to do it properly you need to do a custom tune on the computer. Or put it all stock, drive it likes its stock and enjoy.

I'd offer you suggestions on what injector to buy but you have a lot more to learn first, I feel I would be giving you advice at the wrong time.

Re: New member from Oregon

Ok yeah I have no clue when it comes to turbo and injection. I just wanted to keep it from leaning out and blowing up again. The guy told me that only going up 2 bigger on the injector size that the computer would still read it.
one other question how do I tell if the waste gate rod on the turbo is adjusted right?

Re: New member from Oregon

I would find a new guy to go to, he is FULL of shit and obviously has no clue about computers either, in particular the syty computer.

The rod in general should be half a hole showing when taken off the arm, but 95% of the time boost issues are a sticky arm or bad solenoid more so than adjustment.

Searching here on syty could teach you A LOT about these trucks. Time to get your own tools and sit down and do some reading.

Re: New member from Oregon

I have done alot of reading while I was waiting for my approval and there is a ton of info here. This is a great site. Thanks for your time and info V8TY I really appreciate it.

I'm sure we will talk again. Have a good day

Re: New member from Oregon

I would check you fuel pump. If stock, could be a cause for the hard starts, check valve not holding pressure, or possibly a lean condition while in boost.

Re: New member from Oregon

Yeah I have been told that and I plan on doing that. It sat in gas for 11 years so it is probably not in very good shape. I'm just trying to run some of the gas out of it before I drop the tank.

Re: New member from Oregon

Deny, when your adding boost to any engine you retard timing to keep from going lean. Naturally aspirated is totally different. I read these posts here would you like me too stop by sometime and check a few things out before you start replacing unnecesary items? Most of the guys at the track are old school, I know Im there alot and know them, I have been working with fuel injection since the early 90's.

 

[Typhoon #2131]

Re: New member from Oregon

Yeah That would be great. I'm not the one that set the timing. The guy that put the motor in for me did and I didn't think we should set it over 0 but he said it would be fine.
