turbo exploder on the dyno


mustang dyno...mid to high 11's afr ran the rpms to 5200 redline the power increased all the way up
 
what fuel pressure reg do you have? Get a 4bar fpr out of a dodge.
 
putting a fuel pressure gauge right now and the dyno sheet will be posted sometime this week
 
upgrade on the way should be up and running tomorrow. ill add the progress to my build thread.

WHOA!! When I read the title I thought it said turbo "explodes" on dyno... confused me a bit there... I thought you blew up your truck, whew... I gotta go change now...
 
One thing I've always wanted to try on a boosted 4.0L is to run it with the computer, fuel injectors and MAF from a supercoupe. I think the supercoupes had 30 lb/hr injectors. They're both EEC-IV MAF DIS V-6's and very close in displacement. It seems like it should work pretty good. Someday I'll try it.
 
Supercoupe computer= DIS
Explorer 4.0 computer= EDIS

The supercoupe has a setup just like a DP 2.3. For it to work on a 4.0, you would have to find a way to mount the crank position sensor from the supercoupe on the 4.0.
 
My 4.0L has a crank position sensor... Looks just like the one on my DP 2.3...
 
After some more research, it seems the 94 and 95 supercoupes came with EDIS. I bet it wouldn't be hard to use that on a 4.0
 
You may be right, however good luck finding one in the JY, all I have ever seen is early 90's SC's.
 
The replacement computers are only 100 bucks at autozone. The fuel injectors are generic. Even though they carry a different part number, I bet the exploder EDIS module would work.
 
If your going to go thru all the trouble why not build a megasquirt setup. you can build your own MSII for a few hundred dollars and have a programable efi
 
Just afraid of the unknown I guess. I should really just buy megasquirt for my ranger and jump in head first. I could put some 90 lb/hr injectors, fill 'er up with E85, slap a holset on it, tune it, and see how long an M5OD will take 500 horsepower.

The other thing is that while MS only costs a few hundred, you still need a wideband O2 sensor system and dyno time. If I could take a 4.0 and slap the SC EEC-IV computer and injectors on it and boost it up to 7-8 PSI without pinging or going lean, that would be easier and more than enough power for the project I am contemplating.

My other thought was to use a 4.0 computer and injectors on a turbo 3.0.
 
first of all megasquirt would probally be easier than trying to adapt a SC ecu to the 4.0 or the 4.0 ecu on the 3.0. Why would you even try that. It most likley woulnt work very well. Second your going to need alot more than 7-8 psi to see 500hp. As far as i know no one has pushed past 400hp with the ohv. Omar over a RPS has a properly sized turbo. he layed down 330ish hp and nearly almost 400ft lbs with 14lbs of boost on a stock motor minus a aftermarket camshaft. he also has a stand alone efi and fuel system up to the task. thru a c6 and 2wd. The 4.0ohv is a torque motor not a high reving high hp beast. My m5od has held up fine so far.

You have my ideas confused. I was referring to putting MS on my all forged 2.3T ranger along with a holset turbo, 90 lb/hr injectors, E85, and cranking up the boost to the point that it makes 500 HP (probably 25-30 psi). And fwiw, my M5OD has held up just fine too. But there's a big difference between 270ish (what my 2.3 makes at 16 psi) and 500 HP.

My other idea is to take the broken 2.9 ranger I have in the backyard, put a used 3.0 or 4.0 in it for cheap, and boost that using a different ford ECU to get more fuel in. I'm not even looking to break 200 crank HP there. I'd be happy if it did 0-60 is less than 10 seconds. That would be achievable with 7-8 psi.
