Question about normal and modified gear ratios
Question about normal and modified gear ratios
I purchased a 2002 996 tt about a month and a half ago and I noticed over time that I simply couldn't quite get used to the 1st -> 2nd shift the way I have in any previous car. I eventually decided it was because of the massive ratio gulf between 1st and 2nd which seems quite high to me. 1st -> 2nd is a 1.83x ratio change in the 996tt (vs for example 1.52 in the mitsubishi evolution 5spd and similar ratios with most other close-ish ratio cars)
If I shift at 5k rpm for example the rpms need to drop by 2250 in order to do a perfect match. That seems to take forever. At redline it becomes some 3000 rpm drop to do a perfect match.
So if I did try to force a shift before the correct match speed then the syncros would have to take the load and they may not be able to do it if it's not even close yet. PLUS there's an abrupt acceleration change which would unsettle the car on a curve.
So I always shift normally but that requires me to clutch in, let completely off the accelerator to get the fastest drop possible and then get back on it as it hits the right speed, completing the shift and clutching back in. This ALSO necessitates an abrupt acceleration change if I'm under heavy acceleration at the time.
All the other gear shifts behave about as well as any other car I've had but the first to second is SO annoying that I usually shift at 3k rpm or earlier so I can shift a little more smoothly.
All right so my actual questions are :
A) If I do the 'cheap' upgrade of a very low mass flywheel plus a better clutch will I likely feel the drop speed increase to make me significantly happier?
B) Is there anything else I can do at all apart from paying $10k for a re-gear?
My previous cars:
85 MR2 (na)
86 Saab SPG (turbo)
94 integra GSR
96 BMW 325i
Current:
00 Audi S4
02 Porsche Turbo
