: 6MT better for roll racing?

I was wondering if you guys with 6 speed with the 3.73 gears know if it's better for roll racing?

My automatic from a 40 roll in 2nd gear feels fast. Does the Manual have the same kick from a 40 roll in 2nd?

Also what speeds to the gears top out at for example the auto:

1st: 40mph
2nd: 60mph
3rd: 95-100mph

Manual has a kick anytime you want it to...

If I'm going 40-45 and want to take off then 2nd is my gear. At 45mph (3800) I'm right in the powerband ready to go.

Agree^^^. Perfect RPM for stabbing from a roll

Technically it should be better from a roll, but my guess is between the time you loose in shifts and the time you make up from having less drivetrain loss it would be pretty even up to 100-120MPH. Then I would bet the 6MT's start to pull on the 6L90E as you approach VMax past that.

I do believe all cars in the 10s & lower are autos...:

Drag racing is not 40mph roll racing. You'll find that they trap 1/4 speeds very close to, or 1-2mph better than auto's anyway.

Think you need to look at those trap speeds again! The highest trap speed on a MT I see is 126???

They do trap more because there is less parasitic loss and the same reason why they get 1-2 mpg better.

Re-read my post please and I won't touch on the fallacy of comparing time slips like that.

Yes. Exactly.

LMAO!!! I just loooooove academics! OK... Help me out here (cause it appears I'm a little naive).

On the drag times link, the MT is:

9th on total ET
9th on 1/4 mi MPH
10th on MPH change between the 1/8 & 1/4 (hence the OPs question of who did better from a roll)
Even the 2 autos, one with 10 less RWHP & the other with 51 less RWHP outpaced the MT from 1/8 to 1/4 mile in both ET & MPH?

How can this be?:hmm:

Could it be........ Satin?

Auto's are just quicker than Manual. Always have been. But Manuals will almost always out-trap an Auto.

Yes, you are naive, as proven by this post. I don't believe I need to say anything else.

Could not duplicate.

I had them replace the latch anyway, the replacement seemed to require more force than the first one, but it could have been an adjustment issue.

The new car's latch doesn't feel any different than the one that let go.

Have you factored in DA? Track conditions? All of the other variables? With the manual, there could be a HUGE difference depending on the driver.

Oh how this thread turned lol. It was not meant to be a auto vs manual thread. I was seriously just curious to know how good the 3.73 gears were from a roll lets say 50-55mph where the auto would have to be in 3rd and the manual could be in 2nd.

Sorry Steve! Hopefully the MT guys can give you the answer.

Jim, I think silk would work too. Both a good choice over alcantara...

...you guys forget that us manual guys lose boost in between shifts. That is a very large factor. We could go around it by doing no lift shifts but from what i've heard it's not something us higher hp manual guys want to be doing.

You do loose a little, but we're not running on Turbo's here. The V/E of supercharged engines is directly comparable to N/A engines. As long as you're in the power band there's no 1-3 second delay waiting for the compressor to spool-- it's already running. You're loosing more time shifting than you are waiting for the TVS to come up. Turbo's are of course worse since it's exhaust gas drive and not drive directly off the crank, so when you lift the compressor driving mechanism is acutally removed temporarly, wherein a supercharger is crank belt driven-- and the crank doesn't 'stop' moving.

Yes, more pluses include being faster, not shifting in traffic, not being gay aka "stroking the shifter"
