hey,
I don't know if its just me, but my (88, auto, non turbo) rx7 won't do crap off the line when i floor it. I'm not burning out i'm just not going anywhere either. I raced this 80's Bronco just for fun and until i got to about 20mph the Bronco had about 1 car length on me (then obviously i destroyed it). 2002 impala, had about 3-4 car lengths on me b4 i could get to about 30mph. Do ya guys have any suggestions, or do all 2nd gen auto's launch that slow? Any help would be nice.

 

my friend with a auto GXL says he noticed a difference when he shifts the auto like a manual but I guess you'll have to try this out yourself, because I dont really believe him for some reason..

 

it's a crappy tranny, I don't even know if they make a shift kit for it. It's just granny smooth, and takes a while for it to engage. I guess you could have a TQ converter made for it, with a higher stall, and better fins. Don't know how much that would set you back.

 

might as well convert it to a 5 speed then

 

He pretty much sums it up righ there. Unless ofcourse you only have one foot. and require an auto to drive.

 

alright, so its not me then,. Do they make upgraded torque converters or would i have to get one customized for the car?

 

what are you talking about a NA with a auto tranny should lay down a sweet 17-18 second quarter mile. How much faster do you want to go for a car thats not worth 500 bucks. And if you bought a rx-7 and planned on drag racing you made a mistake. Your car was made to corner and handle in tight turns no drag race from light to light.

 

Welcome to owning a "slushbox". I don't think they are very good transmissions. I have heard that they are fairly un-reliable as well. 90% of all automatic transmissioned vehicles are in the United States. We Americans have such a lazy way of life.

 

Launching Auto How-To:

Step 1: Support the Tranny with a jack.
Step 2: Unbolt transmission from motor.
Step 3: Do you see where this is going?

 

laff

 

Do neutral to drive drops, just rev the **** out of it, then bam, right down into drive, JK!! In all seriousness, your best bet is to swap to 5 speed.

 

No, but if you can get your hands on a trash can, I would advise you to toss that trans into it.

 

The best way to launch it is to brake with one foot, gas with the other until you're pretty near the torque convs. lockup, then release brake and roll into throttle (mashing doesn't help much, roll into it). However, do NOT do this for LONG periods of time! If it takes you more than 2-3 secondsd to brake and rev it up like this, STOP. It creates excess heat in the tranny and obviously isn't good if you do it for extended periods of time. Once you get used to it you can do it pretty quickly and the tranny won't suffer. Other than that, read above.

 

Don't forget the gearing on the automatic cars is horrible. Mines and auto and the gearing just kills me. Not only is the rear gearing crap but the auto tranny gearing is even worse! Combine this for low ET's and slow starts. If you plan on swapping out the rear ever, might as well start with gearing on the rear. It's really funny how a small amount of gearing changes things. Next change for the car is a better rear end with gearing and maybe limited slip and a 5spd swap.

Example: On my 67 stang with a 351w and 4 speed manual I originally had 3.00 gears with a dead limited slip. Well I said screw it and upped the gearing to 3.25 since I was replacing the limited slip. What a nice difference taking off and everything. Now, you may be wonding why I didn't get even high gearing. Well, the old cars didn't come with overdrive so I didn't want crazy high reving on the freeway. It's a nice comprimise between fun and daily driver. Next addon for the beast is a beefy 5 or 6 speed.

 

I have an auto THEY DON'T Launch

 

it depends on the quality of the torque converter... on my mom's benz C 220cdi Sportcoupé I can launch! brake the hardest U can, acelerate the engine then drop the brakes and there it goes.. this is good on turbo engines cause among other things it spools up the turbo!

 

God damn, did nobody read what I posted?

 

I read it.. but since the thread continued I posted my resumed version. care to explain that "torque convs. lockup" thing ?? doesn't it only lock up when it's rotating at the same speed than the tranny?

 

It locks up when the fluid inside puts enough pressure outwards.

Meaning... when the flywheel/TQ is spinning fast enough.

If you hold down the brake, it will rev up... you'll feel the car want to go... let the brake go and roll into the gas like he said.

If you're racing this way, please get a civic... the rest of the ricers do. Like people said above... this car was made to handle... unless you're hardcore drag racing getting really low times, where automatics with drive-lock are best, you should just get a 5 speed.

If you can't afford to get a 5 speed... maybe you shouldn't be out acting like you've got a good car, 'cause you don't... makes a bad name for other RX-7 drivers. =/

Of course it's a free country....

ya i used to have a ***** auto trany... 2 days after i got the car i wanted a 5 speed so 3 months later i did

 

hey now, the rx-7 has been a great car!(compared to my 300zx). but i'll look into dropping a 5 speed in there, until then i'll rip up them corners!

 

Torque convs. lock up at a specified rpm (or around there) at which they refuse to slip anymore, i think the FC is like 2500 or 2700? I don't recall, something like that.

 

Yeah, this dont work. You just cant launch an auto. It just sucks. I used to have an auto, and it was slow as hell and sucked so i swapped in a 5sp.
Like I said, you can launch an auto.. I tried to neutral rev shift, and...well...it just didnt work.
www.rotaryresurrection.com tech -> 5speed swap (or something like that)

 

I did, and I understood all too well.

This is no Benz, this was a woman's RX-7... about 15 years ago. It wasn't made to go fast.

 

I wish I was a mod so I could close a stupid thread like this.

Id Post: "Automatics aren't ment to launch and torque converter won't help. Swap to a 5-speed or live with it."

Thread Closed. But I'm not, oh well
