That box looks like an R154 from a 7M or 1J MKIII Supra. not the best Supra box, but not far off. It would probably struggle at 800WHP, but depends on the weight of the car of torque of course.

Exactly. With that move he has destroyed the fine balance of 944's chassis.

How ever this guy is going about it the wrong way, he is destroying the one thing these cars actualy have going for them.

what's wrong with a 951 engine or your half Audi- half Porsche LOL

The shells and crank are beefier than a Chevy V-8!!

IIRC Audisport was getting over 700BHP in the 1980's with the same motor this guy is using.

Audisport engine is not the same as the street motor........

With the right suspension design and tuning, weight distribution means VERY little on a race track. I've worked on late model mustangs with verified 60/40 weight distribution (measured during corner balancing) that can and do tool nearly any 50/50 car.

Where are the tanks.

And look at that throttle body!
Let me guess.....2 inch ic pipes, right?

The irony is that this will be the guy that comes on here and says US dynos read higher!:r oflmao:

I'm sure that well fabbed tuberific race car will be 60/40 weight distribution or better the way he's going I'm sure it will have all the right roll centers low center of mass and plenty of other features that make a high end race car .
as for the earlier question.
cast iron block
show me any engine pre year 2000 with more than 500 hp per liter with an alloy block

To what exactly are you referring?

To clarify my statement, weight distribution is a lesser factor than many believe within the realm of production based race cars.

http://www.griggsracing.com/article_...articles_id=25

Notice the 996 cup down there holding the TTU record. I'm reluctant to guess the weight distribution on that thing but I'll venture that its probably the close to the opposite of the Mustang's.

Again, not saying that weight distribution doesn't matter, just that on the track there are more important factors to consider. Ultimately, all else aside, I believe that some degree of rear weight bias is preferable on a rear wheel drive car. How much do we think this Audi swap is going to change the weight distribution anyway?

I like the project on the engine side but not on the tranny side.. This should remain as it was originally. on the back.

But as far as the engine goest I totally agree 5cli 20 valve AAN engine is qute stout and can handle alot of power. What you can do here is to throw in VW Caravelle 2.5l disel crank custom rods into 2.2 liter block, have the block overbored by 1mm and then you have nice 2.6 liter 20 valve line 5 witch can handle alot of power. has steel sleeves etc.. Of cours in our cars this engine should be pushed back a little in order to mount it under the small engine bay. And this engine can make more power anytime then our line 4 can handle..

But you know, then again.. its not allways about the power.. You can have a lot of HP but that does not mean that your car is insane quick right?
