I agree with Andrei above.

Although it would be good to have a 996 GT3 cup in the mix too to see how it compares performance wise to the 997 GT3 RS .2

With the same tires I think performance around a circuit would be pretty close.

there was a pretty good review in GTPurelyPorsche last year comparing the 996.1, 997.1 & .2 GT3s ...

I don't think putting a stripper car into the mix is a good idea. There are too many unknown/variables depending on whether the car is stock or upgraded. There are a million mods you can do to a car which will change the results.

Although I have to agree with my little green alien friend that this comparison would be fun and a really good test

I think it should include: .1 GT3, .1 GT3 RS, .1 Cup, .2 GT3, .2 GT3 RS, .2 RS 4.0 and .2 Cup. The ultimate 997 GT3 showdown!

Throw a 993 Turbo in the mix too, because we've all either had one or want one in the future Would be fun to see how it does compared to the modern cars.

thusly

Depending on location and other details, I'd be willing to contribute a 996 cup, 996 RSR and 997 RSR with 4 liter engine to the mix. Maybe even a CGT.....

There are a million mods but there are only 3-4 that are really needed to make the car usable on the track.

Alignment, rear toe links, tires. Seats and roll-bar don't make the car faster other than subtract a little bit of weight. And the rear toe links are a safety device rather than a performance bit.

A full stripper would be fun and I don't think if done right there are that many different ways to go about it.

Most important factor is weight and suspension mods (assuming good tires already). Just because you can choose between Moton and JRZ doesn't mean one is much faster than the other. Finding the right setup on them is the difficult part.

While they may not change the times drastically they do change it little by little and all of it adds up in the end. Having good coil overs plus full solid suspension should turn in better times than just coil overs (given the same driver), etc. Finding a good set up is also hard like you said, so that will make a difference as well.

The tires are also a factor. From RA1 to Hoohoo R6 there is 1-2 sec per lap.

so eventually it all builds up. Comparing stock to stock makes more sense to actually get better (comparable) results.

But if you compare a showroom stock GT3 to a Cup car you will get a misleading result. The gap will be bigger than it is. And you will still not know how fast it really is. It's a fictional GT3 because you will not see one like that at any track, at least not one that is driven well and not a car that was just purchased and the driver is getting used to it.

Put PSCs on a 996 GT3. Michelin Cup slicks on the 997.2 RS. Hoosier R6 on the 997.1 RS. Those seem to be the typical tires around here. Even if you get it wrong it is still a better indication than stock PS2 tires on a 996 GT3 with stock alignment.

Totally agree with Andrei, any street legal car in such a test would need to have the "typical" track mods installed, the stuff that we *all* do to our cars as a starting point. Otherwise, no one will be able to relate, so what would be the point?

sin911

I didn't mean literally off the showroom. A good alignment is a must, corner balance is also suggested. What I meant was as you start diverging from stock with modifications the test results will become harder to compare and contrast.

Put racing pads, flush brake fluid, do alignment and r-comp or slick tires and the car is bound to put 3-5 sec faster lap times. No two strippers will be identical in lap times (probably not even within a second) because of different mods, that is what I meant.

Some good debate going here. The original prpose of the request was to learn just how close the RS is to the various stages of the race car and to keep it all stock in terms of not changing any parts on it, but for sure get proper geometry set up, brake fluid and have MPSC's. As an RS owner, I am very interested in this.

Perhaps we then add another and it's the RS with mods changing geometry, suspension, exhaust, brakes (pads, discs and fluid), 18" wheels and slicks.

I still want to see gen 2 3.8 and 4.0 RS.

Put these up against the Cup and RSR and it would be very interesting.

P.J.S.

if this does not work out and you want to do some private testing with your cars, I will bring a modded .1 RS and you show me yours and I will show you mine :-). (cars that is)

And I will fly out to supervise.

The most accurate guide to 911 race car performance is their price. However it is cheaper to build sprint cars than enduro cars yet in vile wet foggy cold weather conditions, a car with ABS has an advantage.

Informed opinion has it that the race being held later this yeat at the 'Ring will be won by the hybrid.

Professional race drivers prefer the most expensive car...
