Dynoed the 3.1 Turbo Wagon

[TurboZ24]

Well, took the turbo wagon I helped a friend build. Got a much better result than I expected....

 

 

At 6 psi.... 229.1 Wheel HP and 261.7 wheel ft lbs

 

Not too bad, eh?

any pics of this beast? is it a 6000 wagon?

[TurboZ24]

It's actually a 91' Cavalier wagon. I think there are a few pics in the http://www.turboz24.com/Wagon directory.

 

I have more too upload once I finish up my website.

nice pics, talk about a sleeper!! :shock:

 

what turbo is that btw?

[skalor]

Look really good!! What size turbo is that, looks like a T3/T4?? The downpipe looks really nice from the pics. 8)

 

I talked to Al from NJ over the summer. He said you guys know each other as he's a J-body nut too. I meet him at a GP mod day, and we talked about older GM stuff the whole day. Everyone thought we were nuts because neither of us really like our '97+ plus w-bodies as much as our older cars.

It's a T3 .48 A/R stage 2 turbine with a T04E 46 trim compressor.

 

I need too upload all the other pics I have of the setup complete. I was hoping for 250 wheel HP and 320 wheel ft lbs at 11 psi, not 230 and 260 at 6....... So, did better than I hoped.

How does that spool, in terms of RPMs?? I'm tired of the T25 and I was looking at a GT2871R, but I also need a new clutch so I can't really spend $1000 on a turbo.

[TurboZ24]

It isn't too bad. I'd have too check, but somewhere in the low too mid 2000 rpm range.

whats done to it engine wise or is it just a bigger turbo?

Basically a stock rebuild, federal mogul pistons, the only additional engine mods are ported heads, ported and match exhaust manifolds, and a turbo grind cam from Crower.

 

It does have a better intercooler and larger turbo than a stock TGP, but otherwise, that's about it.

Nice Cavi, nice #'s on 6psi as well. 8) Has he suprised anyone w/ that sleeper yet?

 

EDIT: What type of engine management is being used?

[TurboZ24]

Engine management is simply a stock W Body ECM with a modified chip. I need too get the chip worked on, though.

[maybe2fast]

do you work on the chips yourself?

[TurboZ24]

Actually, a guy I was helping with a previous turbo 3.1 Cavalier got the chip from someone (don't remember who). We never put it in his car (he damaged the engine, bad oil cooler line....) It doesn't idle correctly, runs rich at idle, lean past 5000 rpm, so I'm going too see if Jeff can help out with that part. I personally have a Haltech on my 91' Turbo Cav, so I'm not up on programming stock Memcals.

Nice. See...you don't have to pump the shit out of it! . Well sometimes it depends..hehe. Excellent. Nice sleeper. whoes ride is it?

That rich on idle can be the cam causing low vacume at idle..the map reads low vacume..and the ecm thinks the engine is loaded. Leaning out past 5krpm is the stock VE numbers on the chip. You'll need to rise them. Via a wideband and dinotune.

I don't think the vacuum is actually different at idle than the stock cam, but I'd have too check.

 

Leaning out past 5krpm is the stock VE numbers on the chip.

Was thinking it's the program, injectors, or the fuel pump. Have too check it out, but unfortunately I have no equipment too deal with stock ECM's, since I typically dump them on most of the other project cars I've worked on.

 

The Wagon belongs too Steve here in Dallas.

 

Here is a pic when we were at the track. http://turboz24.com/Wagon/DSCN0081.JPG
