Here is my experiences with auto's behind rotors - albeit Jatco variety

My Rx4 street car - unopened FC 13b - Jatco 3 speed (built), no transbrakes were available at this time (mid 90's) small to4 - 58mm front wheel,1.32rear housing,
6000 stall speed - 7inch convertor,DEEP PAN & always used AMSOIL in the trans, top mount FC intercooler..

This car would happily run 11.4 @ 124 all day, could drive it to & from the track ,
& bwould happily cruise around at 60kph in top gear in traffic without killing the transmission - nail it & it would flash to 6000 & destroy rear tyres
60ft's apprx 1.5 & was ok to get on stall

My RX4 race car - http://www.youtube.com/watch?v=KPAXBJvQTS0

Street ported 20b,std inlet manifolds - 3 x std injectors primary,3 x 1600 secondary, GT45 turbo 66mm front wheel,1.15 rear housing.. (small turbo)
once again Jatco 3 speed - 6000 convertor, 4.77 9" rear 31.5x14 tyre.
This combo would consistently run 8.9-9.2 all day ..Any conditions
Best 60ft 1.17 - that was staying on TB after green
Would consistenty 1.20 during racing whilst leaving with good reaction times .45s

At the 2005 4/6 & Rotary Nationals I had 8 passes
3 in qualifying & 5 in eliminations -best pass 9.01 - slowest 9.22... I won this event - even against those inconsistent manual equiped rotors!!

I Built this car to run 9.00's & race in Bracket events against the V8 crowd - it took me 8 passes to reach this goal & the convertor never came out..
My next aim is 8.00 & have changed transmission to powerglide + a larger turbo
one day I wil ahve a track to race at , our home track is closed indefinately & the nearest safe 1/4mile is 900 miles away

Dont forget PAC PERFORMANCE RX3 years ago was powerglide & ran 7.60 @ 180ish

If I were to build a Pro Car - it would be manual

I have also built a street car for a customer with the same specs as my race car
Jatco 20b etc - gets driven to & from work & happily does hundreds of km's cruising when the weather permits

To you guys building auto Rotars, get you convertor size right, use quality fluid ,
perfect your start line procedure & you will be UNTOUCHABLE in bracket events

Then go & have some fun on the street

jason, welcome to the rx7 club.. and congrats on your accomplishments.
going 11 seconds with a small turbo/tight converter is easy in my opinion.. i had a customer car with a jatco, series 5 13B hybrid turbo and stock converter.. it was consistant but it still didnt 60 foot like a stick car. but it was consistant
the bigger the turbo the more lag=less low end= worse 60 foot time and launch waiting for the converter to come up.. bottom line with a 2 rotor
a 20B on the other hand is a different story, more low end torque, wich works in favor with an auto..
one last thing, what tranny is most popular with pac performance now? not an auto.......

Grasshopper you're a nut, lay off the popcorn :lol:

Eric did you try emailing Keas or Al's race glides to see if they'll see you parts to build your own Jatco??? Or are you going with a domestic type tranny insted??

yup, thats pretty much sums it up for viking war hammer have fun in la-la land queer

I know you're type. I've beaten people like you before. You're the type of person who throws up the "RACE CAR" flag after you've gotten your ass handed to you on the street.

You probably thought my old FD wasn't streetable either, since it had a 4 link :lol: :lol: :lol: :lol: :lol:

You know I'm just yanking your chain. I just want to see you at least finish a project sometime in the near future. So far after your FD you have jumped from like 3 or 4 different cars. You can talk all the shit you want and claim you know what your talking about when it comes to auto's and rotaries, but fact is all your knowledge is coming from a few people and watching some youtube vids. Get your shit running down the track with your auto and then you can talk.

With the rotaries and auto's. I'm going by conversations with people from the Aus forum. Since, they actually know what they're talking about. The whole thing with you guys saying you can't run high stall auto's on the streets is just nonsense. I "ride" in them all the time :lol: . Someones gotta set the races up :lol:

Maybe the laws of physics are different in AUS, maybe that's how they can succesfully run auto's on the streets.

My car might not be done yet, but atleast it runs :lol:

Of course the Aussies make it work!!

The tranny fluid flows in a reverse direction just like the toilets & the fact they're using 100% all natural synthetic marsupio oil is a added bonus...


line out..

It seems alot of guys are solving their "Lazy Torque" issues with a 3 step.

Have someone pull you up 6" inches before the first beam. Lock the foot brake, switch the trailing coils off, floor the gas while holding a button for the 3 step. Have the 3 step set just before the back wheels wanna turn). Then, back off of the foot brake a little, let it roll into the beams, hit the transbrake (which overrides the foot brake rev limiter and activates its own), let the foot brake go, wait for the light and let go.

Problem solved. Races Won.

Want to see a example?

Also, Viking, I have been meaning to ask you. On your first gen that you are building for a street car. How do you plan on driving for any length of time with a tiny radiator and alcohol? I am no alky engine expert but I do know they go thru several gallons on a single 1/4mile run.

Just a FYI, ran the car yesterday for an hour. With the car sitting in the garage and the waterpump running. The coolant temps were a steady 110F the entire time. The fan never kicked on.

No just a lot of people asking questions, but no serious buyers. The crazy part is that it works really well.

The debate will always go on about which is better. These projects are FU#*ing money pits so if the tranny will save you cash on your drivetrain and get you down the track it is money well spent.

I selected the higher stall because I was running a 28X9 MT and I thought it work well and not blow away the tires.

What size tire are you running on your new 7?

Did you go with a reverse pattern shifter or did you stick with the basic?

You won't be disappointed I had fun with my car until I took it apart.

Eric,

I would be careful with what most converter shops recommend. Majority of their customer base run V8 powerplants. The first guy I used was guessing and we were way off. The Rotary is a different animal when comes to converters at least that is what I found. It was a learning experience for Mike's Transmission in Palmdale California and PTC.

It was actually funny when Mike at the tranny shop put my converter on his test motor he hit the rev limiter before the converter actually locked up. I gave him the specs and he told me that it was a very loose torque converter. It actually worked out well once I got the 3rd converter in the car.

Good Luck
Albert

Based on your dyno sheet you posted I personally would go with a 5500 stall converter. I started at 4500 and kept bumping it up because it was a slug out of the hole. But it also depends on your engine redline. We all know we can rev the hell out of a Rotary, but what is your engine redline setup for so you don't blow your motor. I don't know all your engine specs, but to keep things on the safe side I never revved my motor past 8,500 and it stayed together for a long time. Going straight up in the air is not the goal so if your new setup is making good torque numbers like your old setup you should be good with a 5500 stall.

What RPM did you launch your old setup at with a stick tranny? Probably much higher that 5500 would be my guess.

My goal was always to get a decent launch out of my car on the turbo only with a 3 step. It worked well, but I figured if I wanted a better 60' time squeezing it could bring those numbers down quickly.

Hope this helps.

Could you explain to me what you mean by 3 step please?????
