No, you are slower

Haha JK

 

I mean shifting from 1st to 2nd, 2nd to 3rd, etc. without using the clutch. I don't do it all the time. Shifting into 5th and 6th without clutching is problematic for some reason and I don't do it.

 

not using a clutch at all sounds insane - lol

I see people at the track "powershift" - ie - keep right foot pegged and simply shift gears with the clutch as fast as possible. Even that treatment is iffy on a driveline if not executed perfectly, and can easily lead to a mechanical overrev if you miss the gear altogether

personally, from what I've seen, powershifting can increase mph, especially on any type of 3-4 shift....you do not want the nose dropping at those speeds as you will surely drain off mph trap. but it is not as huge a variant as alot of people believe on elapsed time capability. You can still execute very low et runs for a given car with "granny" shifted shifts, as long as they're crisp and near the rpm limit. Drag racing still boils down to a 60ft time/launch for the most part....shifting down track, especially 1000 feet out is a far second place category in regards to et's

100% grandmama shifting right here.

what makes going from 1-2 not powermatic compare to 5-6? it sounds crazy not to use the clutch to shift.

 

I was not aware the shifter can even go into gear without clutching... I do know that you can shift out of gear (into neutral) without clutching, I've done that a few times by accident.

 

What makes 5th/6th more problematic to shift into w/o the clutch is the fact that they have different/inferior synchros than the lower gears.

If the synchros are making any difference then you are not matching revs perfectly enough and need to stop trying to shift w/o the clutch. You're simply killing the synchros on the lower gears and luckily they can handle it (for now).

 

you guys are weird complaining

just go from 1st to 6th. simple. 1 shift, and you save fuel!

 

and your clutch life^^ =)

i skip gears all the time

 

I think there are double synchros instead of triple on 5th and 6th gear. I do not shift without clutching all the time, I got lazy after I drove a truck for a while. You never clutch in a big truck whether shifting up or down through all 12 gears except when starting off in 1st. I got in the habit and learned to shift at the right point in the RPM band. If you do it right, it's not problematic and doesn't prematurely wear the tranny, buy you're right that it is safer to just shift using the clutch. I've either been really luck or really good, because I have never had to rebuild a transmission or a clutch yet and have gotten over 250K on some.

 

wait...so youre saying you dont use the clutch at all when shifting 1-4. i dont get it, wouldnt that grind in every gear? isnt that what a clutch is for?

 

NO, it doesn't grind at all if the RPMs are right. It just goes right out of one gear and into the next.

 

But please don't attempt these on your car unless you know what you are doing. Do this at your own risk if you wan to try it.

 

yup ... if you dont know how... the first time you will hear this = *inserts a horrible Grinding now that makes you cringe* and that doesnt sound good at all

 

For all those that want to know why you are grinding in high gears with a clutchless shift.

1st, 2nd, and 3rd gears all have triple cone syncros
4th is a double cone syncro
5th and 6th are single cone syncros, which is why it is harder to shift without grinding.

If you want to know why this matters, do a search as I explained it in great detail on another post.

 

someone should make a video. and what are the rpms?
