Do you have the 4speed or 5 speed gearbox? The 5 speed would put your top speed at close to 190mph at 6800RPMs and the 16" stock wheels! You must have a very serious engine in there!

Does anyone sell and under body tray for the old cars? Could I chop up a 993 one?

My engine is at the max for CIS(probably a little past the max
) so it's making some decent power. It doesn't take much to make 2500lbs fast though...

I don't know how effective it would be if the whole car was covered then the engine open. Some of the 993 guys compain of high speed instability without the engine tray which is unacceptable since I see high speed often. I am moving back to Phoenix so needless to say I need the engine to be able to keep as cool as possible. What do you think?

There is a commercial plastic place in town so what I was thinking about doing is mocking up something like the 993 4 pc. tray but for the suspension of the 930. Some heavy duty plastic should do the trick.

The way I see this is the following. I have seen race 996 RSR P-cars have it as late as a couple of weeks back during the 24Hours race, and I mean full underbody CF panel, not diffuser at the back, when asked, Franz Konrad said that it was custom made for him, and he knows a thing or two about racing Porsche cars.
Now to aircooled cars, I have seen the fastest 993GT2EVO to ever run at the 'Ring have a custom made one for it in CF at Manthey Racing, going all the way from the front to the back and ending in a tail diffuser, Manthey also knows a thing or two about racing, and more specifically about Porsche handling, they did not give him the first 997RSR to test it only because they like him.
Porsche fitted on stock air-cooled cars for a few reasons but mainly because of sound emissions control, and improve aerodynamics/reduce lift. I lived in the hottest countries on Earth and have seen 120k mile 993s with the tray never removed, running as strong as when new. So the question is, does it improve aerodynamics, definitely yes. Does it hurt your engine? Watch the temps, but I hardly think so, as long as you are not caught daily in heavy traffic in 120F.
If you drive at the US speed limit all or most of the time, I would say forget the tray. You might have as many opinions are there are POrsche cars in the world, this is just one of them

I would think that if you wanted high speed stability some splitters and a larger wing would work. I know I got sideways at around 165mph in mine, wasn't a crazy kick, but enough to make things slow motion. Asked around, general concensus was lack of downforce. As for the diffuser, sure, but with 930's ground clearence, especially when launching, I wouldn't want to. That is of course if I was using stock torsion style suspension.
