I was looking at the SCCA website, and a question popped in my head.

Why are sequential transmission prohibited, in a lot of the track events ???

I just want a straight forward answer...

Thanks In Advance For The Help.

 

What's that mean? I thought all transmissions are sequential.

Maybe they mean those paddle style shifters or tiptronic trannies?

 

manuals aren't sequential -- i can hop around and do the 1-4 shift (common on vettes) or downshift from 6th to 4th directly without going through 5th.

by comparison, a bike is sequential. you have to click through each gear everytime... same goes with alot of these manual automatics... you can get from 1st to 3rd, but you always have to go through 2nd.

blaaah. i don't like them at all. everyone whose into F1 (big time in europe) loves sequential... in the US (NASCAR fans) we want our clutch. and that's the reason the M5 and M6 will be available with real 6-speeds, not just their SMG.

 

I'll bet Derek (HDDP) can respond with the question about sequential gearboxes in SCCA events, post the question in the "Racing" section and perhaps you'll get your answer.

FYI, on the issue of Sequential gearboxes. If you race/drive primarily road courses, where you're shifting constantly, using both brakes and gears for slowing the car, hitting the "right" gear is crucial, missing a shift (wrong selection) can be disastrous. With sequential gear boxes, you always know which gear you're going to get "next" (up or down). As "Former" pointed out, Nascar doesn't use sequential boxes, because they're not shifting all that often and, other than the road courses (2) they're not really shifting (usually) on the track, mostly as they are entering, exiting the pits.

HOWEVER, do you really want a sequential gearbox on a street car for daily driving. Well, unless you're obsessed with driving, this could get to be a real pain in the @ss in everyday conditions.

As I said, ask Derek about the reason behind the SCCA issue.

 

I still don't get it.

 

The rules for most sanctioning bodies running stock or modified stock cars, (SCCA, various historic racing groups, etc.) require retention of the stock transmissions.

In many modern pro series, such as the European touring car series, the standard box is replaced with a pure racing transmission, using sequential shifting and straight cut dog gears (a la motorcycles). These -- by specialized companies like Quaife, Xtrac and Hewland -- are lighter, stronger and faster sifting than most stock boxes, offer the ability to change ratios, and will handle much more torque an very high temperatures. These also cost well over $10k, which would represent the kind of "checkbook racing" most amateur sanctioning bodies want to avoid. These racing boxes would be as bad on the road as most stock trannies would be taking the punishment of racing.

 

First Rule of Racing: Just because it's banned doesn't mean it's better.

 

Second rule of racing: Just because it's banned = Just don't get caught!

 

Lol, you must be into Formula 1

 

I'm into ALL forms of racing!
