Does anyone know what computer and prom this would possibly use?

First, this thing has intercoolers, so the first thing to figure out is if has a power adder, or if it running them on a n/a engine.

 

Okay, I went and found it, this is the TwinTurbo Callaway car, not many people would purchase intercoolers if they were not boosting.

Are you plannig on running turbos? If so, I think the best to do is tune it yourself, seeing as every tune is different.

If you are not planning on boosting, then I wouldn't worry about it, because the tune will not run near perfect in a n/a engine.

I guess I was really wondering how difficult a project like this would be to pursue. It would be nice if someone had technical info on this engine. Like block type, pistons cam etc. I know it wouldnt be cheap but what is.

 

With two intakes, due to the two intercoolers, I'd say it would have to me a SD system. Looks like their old Sledge Hammer. Calloway has always had some ties to GM so I'd imagine it has a 1227749 Syclone ecm in it. If the vette is 89-90 or earlier it'd be had to say what they may have used.

I'm sure the prom was done on a dyno, and is a one-off.

 

The Callaway Twin Turbo Corvettes (RPO: B2K) used the same '165 ECM and $32b code that the 86-88 Corvettes used. There was also a microfueler computer installed under the driver's hush panel that controlled 2 extra injectors placed in front of the throttlebody.

 

If it did why dont i see a maf or am i missing something.

 

You're missing something! Take a look here: http://www.motorsportsdigest.com/cars2.htm

You can clearly see the MAF in front of the engine in one of the pics.....

 

Are the parts stock? Did they just remove the screens or something. Anyone know the engine specs? I have that exact ecm and maf. I see this has been thought of before. I would imagine it would be possible with a 7730 as well.

 

There is a ton of research and work in that setup.

I highly suggest you go here...

....that is a forum dedicated strictly to Callaway Corvettes with many extremely knowledgable owners. Good luck.

 

I found a tech break down of the engine. Its the sledgehammer though.

I found an exact replacement for that turbo online for $569. Thats the same one the 1987 callaway engine used. Made by Warner ISHI. The garret that probably produce alot more power are about $900 each. I see a pair on ebay for $500.

 

What is your goal?

 

Just an idea in the back of my mind. Maybe one day when i accumilate the parts i can make it happen. I have a 383 stroke i built for now. Maybe when this project ends it may be something to juggle around a while with. Im thinking 5 speed (if it can handle it) and the dual turbo as well as a twin intercooler with hardened aftermarket parts.
