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.......

Thanks for the welcome 680

re Pac's cars ,are we talking street or race?? if street 9 sec & slower Pac have been using jatco & c4 for 13b power cars, a few still sneak through with supra 5 speeds.. Their 20b power (street) usually are Jatco or Powerglide.
Anything half chassis the generally go clutchless manual

I you get a chance have a look on Ausrotary.com & look in the cars for sale section especially under the username offgutz - he seems to have owned a lot
of Pac built cars that run mid to low 9's using 13b's - most are auto

One thing re watching vid's of aussie auto rotors - a lot of racers here dont care about reaction times - they generally are going for glory trying to pb...
most dont even race at competition type meetings

Get that c4 sorted & enjoy

PS - 20b's do everything easily, even taking your cash

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??

:lol: :lol:

I emailed KEAS for a list a long time ago and have decided to use a C4 instead. I already have a built C4 sitting in the garage and all the parts, I just need to have a converter build which I'm in the process of doing.

The original thread starter (tinmann55) is ordering his parts through KEAS to build his Jatco.

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:

Oh, c'mon. At least be a good sport.. That was some funny shit I posted earlier. If you can't laugh at that then there is something wrong with you.

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.

I know, I know..........

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:

Busted7 08-09-08 02:30 PM

Eric you know the tranny fluid in aussie land sets in the top thats why they can do it. DUH!:scratch:

Yeah, I never said you couldn't run a high stall converter on the street. I was saying is it streetable and do you really want to. Every tranny expert I have ever talked to about running stalls on the street is to never go over 3000 or it is just a pain in the ass and just beats you to death. I had a camaro- I know(sorry)- before with a 3000 stall and it was a biotch to drive on the street. I couldn't imagine driving a car with something over 5000. Saying all that some people have very very high thresholds for driveability than others. So I wish you all the luck on your project and can't wait to see your future thread on " switching from C4 to G-force".:)

RoTaRyBoYz 08-09-08 07:51 PM

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..

now i know how they do it, im all set then :) ill cal pac performance this week to order up some fresh marcupio oil :)
nice :)

Busted7 08-09-08 08:02 PM

It ships in a convient pouch!

RoTaRyBoYz 08-09-08 09:14 PM

Thats top secret info I wasn't supposed to give out, so consider yourselves lucky!!!

As Busted just said, the oil is shipped in a convient pouch and not a regular plastic container to avaid plastic "bleed" contamination.. PM me of you are interested on purchasing a case of this award winning technology... BTW, this Oil DOES NOT COMPRESS like the other brand name oils we know. On a stock tranny, your shifts well fell like money on your pocket, because they're nice & firm..

It's strange no one got into specific detail about the positive effects of reverse fluid flow.. Those Aussie blokes are so darn lucky!!

#6 circle Gamakatsu, fresh bunker chunks.... cast off

13B-RX3 08-09-08 11:07 PM

Squeeze out, it's all about the squeeze out. That and 30w ball bearings.

I'm the nut? Your just plain wacky. Cookoo cookoo. How much rum have you drank today?

RoTaRyBoYz 08-10-08 12:28 AM

Out of all the people I honestly thought you was going to be the fish to bite :rlaugh: ..... I guess I need to change my bait or chase after dumber fish :lol:

Just for the record.... I'm sober today :lol:


Eric why don't you Email your questions to SpeedFM.com.au, maybe Anthony Rod(Maztech) might answer it on Wednesday's show.... Do i have to think of everything around here!!!! :lol:

Viking War Hammer 08-10-08 10:06 AM

Can you just email them for me, since you've been the acting mod around here? :)

hahahahaha , they can start with that and move on up to the others :lol: it has a 27hp generac on it and goes around 10mph:scratch:

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?

All this two step and three step is for the birds, I'll stick with my 1 step.

ultimatejay 08-10-08 11:35 PM

That mower is badass. I'll take that for a spin anytime. :)

Never thought of the three step , I had the 2 step in mind and have the computer to retard the timing when the 2 step was activated to leave on boost .
