It's not that modified!

I actually got a price on regear - moving 5th to 6th and using custom 3,4,5. Problem is I'm afraid it'll be too short with a 4.0 R&P.

I think the gear change would be beneficial overall even on a fast track like VIR full and totally help on short tracks like VIR S.

KICK *** VIDEO!

I'll always pick regear over ring and pinion if it's an either/or question. Ring and pinion doesn't bring the gears closer together. There's more to be gained by getting the engine into the right RPM band on the upshifts.

The only thing to watch out for is 3rd gear. Anything shorter than a 1.65 ratio and you've got to time the life like you time an engine. Anything over 25 hours of track time and you'll want to start planning for service on the box, with 40 hours really being the outer limit of what I woul run anything from 1.684 through 1.789. A lot of shops that consult on these regears don't tell you that, even many of our dealers don't. So I try to put it out there. We've seen too many 3rd gear failures already this year on short 3rds.

Thank you for the advise! I already have the R&P so it would be in addition to, which is what makes me think it'll end up too short.

Talk to PJS996GT3. He'll talk regearing with you.

Or take the example of the 996 Cup Car. Most of those were delivered with a 1.56 3rd gear just like your street car. The short ring and pinion does not make everything automatically too short. If you compare the Cup to the street, 1st and 2nd are taller,offsetting the short ring and pinion. Then you go from there with the gears to choice.

But once you've got the 4.00 R/P the stock 5th gear as a 6th will definitely be way too short for Sebring. You'll want a gear between the stock 5th and 6th gears in 6th.

P.J.S.

I have 8:33 ring and pinion (4.125) and regeared first thru fourth all done thru guard and with matt tutoring me along the way

It is divine

Alex are you using 6th gear even w/ the 4.0?

Also what sort of MPH are you seeing on the back side at VIR? Indicated and data (if you have it).

ukrbmw

Fritz - actually, you're ask a valid question. I've never used 6th at the track, so I guess it wouldn't be a problem. If I recall correctly the most I got per TM was 150-152 on the back straight at VIR.

I still owe some people data - sorry. My regular computer is a Mac and I have a separate laptop just for TraqMate, but it has no email - which I'm fixing now.

ukrbmw

We can't mess with 1st and 2nd in a 6GT3 (well, at least not for a reasonable sum of money). So basically, you can play with 3rd and up. I frankly never use 2nd on any of the tracks around here and as Fritz just made me realize I never use 6th either.

SH || NC

Come to CMS Sunday & Monday - we can use 6th on the oval

ukrbmw

Sorry - can't do. And by the way - I'll be shocked if you actually "need" to use 6th. People with very large "things hanging between their legs" will do 140-145 around turn 3-4 and that's still 5th gear.

Dredging up an old thread here. I’d like to know what lap time you’d expect to see at RA from a well-driven 996GT3 that’s basically stock (power, suspension, gearing, weight, etc.) on PS2’s. I’m not looking for the single fastest lap such a setup ever produced, but the time you’d expect a typical red-group driver to lay down on a relatively clean lap.

ukrbmw

I think on PS2 you should be pretty happy anywhere in 1:37-1:39 range.

fbirch

Thanks. I've certaintly got some improving to do!

O.K., can you handle the truth?

First, we all know that our 996 GT3's go from mild to wild and the track monster cars are about 5 seconds a lap better than out of the box stock guys. 5 seconds is a lot so for some of you madman, I suppose you might be 10 seconds better but you're not driving that one to the track.

Then let's start with streetable cars, driven to the track on tires that would not immediately crash if a Florida micro-shower just happened by, retaining a/c., two seats and stock sound deadening, running on pump gas, no overbore; maybe aftermarket exhaust but no significant internal mods.

Now that we have a base line, lets look what some of the other cars do professionally timed as a benchmark. Best is to look at the Cayman series for HSR. These are lighter, more modified but with less motor (except that their motors are tuned within an inch of their bare existence), and the best times are 2 min, 21 sec. They got shaved tires, the best steel brakes money can buy, polyurethane throughout the suspension. Does your car have all that?

So, if you can get your streetable car anywhere near that time, you're a hot shoe. I would say 2 min 25 sec is probably the real time for anything driven back and forth to the track. That's reality. Send up a video from data acquisition verified by one other disinterested person and you'll convince me otherwise.
