Dog Gears?

[Car_Ram/Rod]

Hey guys, I'm making plans to build a street/track car and I've been considering whether to go with a standard synchronized manual tranny or a Dog Box. Is there a difference in the way you operate a tranny with Dog gears? For example, would I need to double clutch due to the lack of synchros? Also are there any benefits to dog gears other than high RPM shifting and strength? Would this type of tranny be totally unstreetable? Any input would be greatly appreciated.

I'd say, stick with the syncromesh tranny. You'll do better... cause syncro's were designed for a reason. They'll help you out in the long run.

Stay with synchros if at all possible. If there are no synchro gearsets available strong enough for you, then you have no choice. I'll probably have to end up with a half syncrho/half box set, cuz there are no affordable strong full sunchro sets for my car.

Just to clarify, are Dog Gears like straight-cut gears with no synchros? Driving a car with no synchros would give you that racer-feeling for a while, but it would get damn annoying during, lets say, your morning commute. It is streetable, but not practical.

That's my .

Are you talking about using dog gear teeth? If so, those type of gears are the best way to reduce friction and improve shifting speed. Other than that.......Dont know what else you could be talking about.

I'm pretty sure that's what he's talking about

Dog-geared tranny is great for all out drag racing and the upshifting is quick, fast and dam near bullit-proof. This is in no way a practical tranny for use on any type of street driven car. Dog-geared tranny's aren't made for downshifting!!!!

no down shifting=ouch!

every time i think about some group N spec dog gears i start drooling...i know a lot of compaines are developing or have in production heavy duty syncromesh for dog box trannies...and who says they arent made for downshifting??? sure you have to use a little actual skill and finese but thats what seperates a good driver from the wussie playing Gran Turismo

Yes, I'm talking about dog gear teeth lol

No it is what seperates someone who has actually had to deal with 1 and knows what a hassle it would be on the street when it has no real practicality or need.

Hey GTStang you have experience with these tranny's!? How is operating one different than conventional? I'm assuming one would have to rev match to deal with the lack of synchros but what else, if anything, is different?

[GTStang]

My expirence with a dog-geared tranny was a T-5. It was in a customer's full drag Mustang(trailer queen). We had the car to do an engine swap for the drag season coming up. We have a nice long strip behind our building lil less than a 1/4 mile were it's just factories. That's is where we go to ummmm test cars out.... hehe.

Any way I drove the car around the block thing a few times and was just making sure everything was ok. I got on it hard and powershifted 1-2 which is the reason dog-gears are used cause of thier strength to do full power upshifts. It upshifted absolutely fantastic but them downshifting was a real pain in the ass. I know you have to rev-match and how to do it but it was still a major annoyance. Sure with some practice you'd get use to it. But why go through that pain everyday for a tranny set-up like that? Your not going to be power-shifting all day long....

i have 91 mr2 with the 2nd gear syncho destroyed.
i mean no downshifts w/o rev-match.
after two days i don't even think a just heal-toe in all downshift.
