Has anybody worked out yet a useable gear ratio config for Watkins Glen? Any T/A mod set-up help greatfully received. Alan.

I fear I may never run Cup cars again, ever. Surely others are running T?A physics by now? (Or is the quiet precisely *because* others are too busy driving/grinning to post?) Alan.

Could be because several million of them are without power right now. Mine just came back on an hour ago. "Alan" <[email hidden]> wrote in message news:bhj8rr$on7$[email hidden]... > > (Or is the quiet precisely *because* others are too busy > driving/grinning to post?) > > Alan. >

The mod is not available, but Jan Kohl posted some instructions on how to unlock the physics while using the cup cars, the TA handles beautifully and I cannot wait for this mod to be fully realised. See: http://www.tptcc.com/board/viewtopic.php?t=609 (It took me an hour to do some 70 cars, but you only need to do 1 to test drive alone rather than race) Just upped the ante to 207mph thru Masta Kink FLAT no lift wheeee! Come on, now theres a challenge, I can't race multiplayer with it yet so have to have *some* competition, who's gonna beat me at a Masta Kink T?A challenge *throws down gauntlet* Alan.

Thanks for the info!

I should add that you need to be patched with the leaked/semi-released 1.1.0.2 version *and* the Project Wildfire Busch Grand National mod before following the above instruction for TRans Am, The PWF BGN Mod is available at various mirrors now. Alan.

Maybe too late for you but if anyone else is interested I found these to be reasonable: Diff. 3.625 1st 2.067 2nd 1.611 3rd 1.350 4th 1.185 5th 1.083 6th 1.000 That's a pretty reasonable close ratio gear set. Use the diff ratio to adjust if you find yourself redlining (which you might since I am still a bit slow here), but I think the ratio spacing is pretty good.

BTW this is probably not the final TA physics. I noticed the ride height still has the NASCAR limitations, whereas T/A rules allow the car to go down to 2.5 inches of ground clearance. Also the wing angle should only go to 30 degrees. There are probably more things that need to be changed too, like the track bar, etc. The rules can be found here: http://www.trans-amseries.com:24009/p/file.pl/502/2003%20Technical%20Specifications.pdf Really this seems more like NASCAR physics with just a lighter car, more downforce, and 2 more gears. Nevertheless it is already HUGE fun. Looking forward to the final version.

Whoops, scratch what I said about the track bar, they use live axles so track bars are allowed. Boy these things are almost as primitive as NASCAR. BTW unless that link is old the rules only allow 5 speed trannies. Can anybody clarify? Are the rules posted online out of date or am I just looking at the wrong race series altogether?

The clue is to set your top gear to 1:1.000 and adjust the final-drive (differential-ratio) to match your top speed - and then adjust the rest of the box to match. Unless fuel economy is a vital factor - you never want overdrive on a racecar. -- eD_
From what I've understood - we'll be forced to live with the limitations/settings of the original NASCAR-garage. Real shame 'cause it sort of limits and ruins the simulation of a T/A-car. -- ed_

All other things being equal, what is the difference between the following gear sets: top gear 1.00 + rear gear 4.00 = 4.00 final gear top gear 0.77 + rear gear 5.17 = 4.00 final gear (approx) i.e. why not overdrive if the final drive ratio is the same? Or am I so far out in left field I don't even know it? Educate me. Thanks, Gerald
Doubt that it makes any difference in a sim. In real life it makes a difference to gear strength and durability. The higher the diff ratio the weaker the diff is going to be. "Gerald Moore" <[email hidden]> wrote in message news:[email hidden]...

Overdrive means that the gearbox is running more rpm's that the engine, whilch mean you'll loose vital momentum and and that in-turn will kill your acceleration. -- ed_
>> top gear 1.00 + rear gear 4.00 = 4.00 final gear >> top gear 0.77 + rear gear 5.17 = 4.00 final gear (approx) >> In a 1.00 to 1.00 ratio, the trans input and output shafts are basically one straight shaft. When the shafts turn at different speeds, there's more friction and side loads.
