I have seen a lot of autos with built trannies up for sale lately. Does anyone know the drag times for these cars. I know most drag cars are auto if they want to heavily compete and I wonder why more effort hasnt been put into the tranny of the 7. I know this car is not a drag car and was never intended for it, but I am a little Shocked that you dont see more of these set ups. Any info would be appreciated.

Thanks

best bet on this would be to search

I have. There arent many results out there for what I am specifically looking for. Like comments on why there isnt much info in this area. Just curious to see if any of the auto owners would like to post their drag times.

ejmack1

Most auto drag times are going to be 13+

there is just not a big aftermarket support for the auto in the car... mainly I would think because of the pitiful amount of torque.

RotorFrank

WRONG...
Chuck from RE had his auto up to 450WRHP... If that cars makes in 13+ i'm selling my car now.

Also, the 9.72ish video that is very popular on the web, the red rx-7. IS AN AUTO with a Transbrake.

I would imagine a lot of the uber-fast drag cars that run autos are running aftermarket automatic drag racing trannies, not the stocker.

I was under the impression that the stock tranny wasn't that stout. Like Mazda rummaged around in the parts bin, found a tranny, and threw it in the car to sell some more cars.

But, prove me wrong if I'm wrong . I just have never really paid attention to the automatic stuff - drag racing isn't my bag .

LMAO... ok there is one RX7

don't tell me Im wrong jackass or there would be 1000's of auto rx7's puttin down that power, and we would not see so many Auto - > Manual threads.

ejmack1

Offspring of the MPV tranny, must not have done that much research....

RotorFrank

Manual conversion are for people who do not know what to do. Unfortunently, with all the fast and fruitiest fashion, most of the poeple in the U.S think that manual is what makes the difference. With all the evolution that cars have done by now, you would imagine that a stick and a pedal would not be the best thing.

Its just not a question of performing better, its a question of costing less money and beeing simpler. Anyone with the funds and the knowledge would tell you all that automatique transmissions are the best in the world. Compare most of the fastest cars on earth.

Anyone with the right knowledge would tell you, to buy a level 10 reinforcement kit for the tranny so it could witstand more power, and buy the newest addition to our arsenal, the PCS.http://www.powertraincontrolsolutions.com/

Give it a year or two, and you are going to see way more autos going under the 11-12's.

ejmack1

a year or two? I just dont see the auto aftermarket getting any better

RotorFrank

The PCS as you may know, is only a very recent developpement, with an outstanding support i've heard. It's so new, that most people do not even know it exists and have yet to see it work on a drag strip or on this website. Let the word get out and you will see alot of difference.

ejmack1

so there should be tons of fast *** auto 7's in Japan, lets here from them... They have so much **** over there I want to see them...

RotorFrank

PCS was developped in the U.S. so obviously they don't have that kind of accessorys. Are you saying that auto FDs can never be as good as a Manual? Have you ever tried a auto FD ejmack? If not then how could you tell...

oakridgerx7

hell, Id own one! Youd figure with a level 10 tranny upgrade, 4.10 rearend, and a high stall(3800 or more). I bet that thing would haul ***! You would never be cussing the car when you got caught in traffic.

RotorFrank

You mean to tell me that manual do catch on fire in traffic or the other way around?

To answer your main question, i would say because people listen too much to what the "so cool bunch" that manual are better. Which is totally wrong since its only a question that its a little more expensive. They are comparing a stick and a pedal to a Hydraulic/Electronic transmission.... with the right tools, you could loose them in a giffy. Not to forget that with the New powertain system, you can turn your Auto FD into a fully controllable Clutchless manual FD. (read the brochure)

They maybe have the same size/cassing, but MPV do not have 16 litters oil pan to substain high heat.

ejmack1

Im sorry but no matter what I still enjoy driving a manual car...

If i was drag racing for a living, i guess an auto would be a better choice... but how many of us do that?

RotorFrank

I know what you mean, i was just stating that you do not need a Manual rx-7 to be fast, and enjoy a good and fun ride. Rebuilding the tranny is only for reliability, and the little computer is for driving the car like a manual but without a clutch... which can also be a blast.

If you tell somebody to swap their tranny to have more fun and see the full potential of the car, your asking them to put 2000$ on the car when they could pay 700$ for a computer that makes the car manual w/o clutch. Which comes down to the same.

spekdah

I would have thought that an auto that has been tuned well should be shifting gears at the optimal moments therefore let the ECU take care of the shifts and concentrate only on the accelerator? ( for drags I mean)

speeddemon7

whoa first time ive heard of this.do you have this on your car?
cause 700 does sound pretty nice for a controller for the tranny.
plus i bet you can use a apex power fc without having to worr about losing the hold feature huh?

I have a single turbo auto rx7 with the PCS computer. it goes a long way towards a fix, but it is not a cure-all. launches from a stop are still a problem. no one makes a stock trans brake for the fd. you can make a true manual mode, but where to mount the shift buttons? Japanese market fds, post 99 don't have the same ecu trans problems that we have, and therefore are open to the same aftermarket as the 5 speeds. it's really a matter of personal preference. sometimes i want to swap, other times i want to stay auto. the auto does keep the turbo "loaded" throughout all gears, just plant your right foot and go. the boost never falls off. sometimes i want to row through the gears too. to each his own. don't underestimate the cost of maintaining an auto. it is not cheaper than a swap.i spent $1500 in rebuild parts (TC+rebuild kit), $3000 in labor for the trans rebuild, $900 or so for the PCS, $300 or so for the sparco wheel and accessory shift on the wheel button kit (which didn't work out). So $5400 for trans stuff alone-could easily have swapped for that, and I might in the future (t-56). Beware anyone who jumps in to say ALL of anything are (insert derogatory comment here).

speeddemon7

thanx for the good info weaklink.
I was wondering if this cure all was just that.From the looks of it.
Auto to manual is still cheaper and probably much easier once its done and over with.Change the clutch and call it a day.lol
I doubt that anything cam cure the low end power loss that autos exhibit.
short of a transmission brake or the auto to 5 speed swap.
I wish things were different.But they are not.

RotorFrank

We'll to make a trans brake, its only a question of modifying the valve body to build up the pressure in tho solenoids. Which could be adapted by someone with experience in competition transmission and rebuilds.

So what are you saying weaklink? i've been following your questions on the PCS forum, and you seem to have had one of the most complete help from the owner that i've seen in a long time. You could also install a Stall torque if you wanna improve your performances at the track.

So how come your true manual doesnt work yet?I should think that by now you got all the information needed to make it work... is it only cuz you don't have the knowledge or experience to do it? (just a question)

BP0192

Okay so theres alot of talk aboput whos better, but what I wanna know is is there much difficulty in the auto to maual swap. I'm looking into buying an FD but its auto, I want a stick, the Mazda dealership said he's do it for another $1500. Is everything pretty much the same in a stick? What are some of the problems/other things I should look out for? Is a auto to stick as good as a stock stick? Help me out guys. Thanx.

RotorFrank

For that type of question, there is alot of threads that take care of it. But, for 1500$ thats for labor only. Parts and etc will cost you more. Other than that, you do what you want. But i would never change the original setup of a car by changing the transmission. And overall, anyone on this forum will tell you that if you want a manual, then buy one. Cuz your in for one hell of a headache swapping it.

eViLjAy

i can see how the auto could be usefull for say bracket racing where consistancy is the object of the game. Have you ever tried to find huge stall converters or reverse manual valvebodies for a mazda trans? Im guessing the local pep boys dont carry it.
Imo mens cars have three pedals
