Launching a Falcon fitted with a trusty 4 speed BTR automatic transmission off the line has always been a daunting task. The high ratio first gear in the BTR 4 speeds never gave Ford fans a chance against the low ratio thunder of the Holden TH700.

The task of launching a falcon off the line has been left up to clumsy diff ratio changes, which is great for the drag strip but only leads to huge fuel consumption on the Street. Matched with the cost of re-calibrating the speedo and altering speed limiters to get your vehicle running correctly, only makes diff ratio changes a very expensive and stressful task.

After two years of various testing programs, Jim Mock Motorsport has come up with the answer. The new JMM 3000 series Performance Stall Converter for 4 speed BTR transmissions will transform the Falcon owner’s high ratio BTR 4 speed slug into a line munching machine.

Brenden Mock from JMM designed the converter to aggressively stall to the desired lockup speed and launch. Quite often tyre smoking is a result. Brenden wanted to keep the street ability of the auto as well, so light throttle driving is still as per normal and the overdrive lockup plate takes over while cruising or on the highway, keeping fuel economy to the max.

Matched with a JMM-DEV5 Engine Performance Kit and a 3.45 ratio limit slip diff, the JMM 3000 Series Converter will flash to 3100 rpm instantly. If fitted behind a stock engine, the stall speed of up to 2500 rpm is normal. In Basic, the more power you make the higher it will stall. If used in conjunction with a turbocharged setup stall speeds of well over 3000 rpm are an easy task.

Jim Mock Motorsport state “The main aim of the converter is to keep a sensible diff ratio and be able to launch the car hard off the line. At the same time, having a torque converter that actually works and doesn’t continuously slip once past the stall speed was a big task. Some modified converters will stall and then slip their way thru the rev range basically chewing the fuel and loosing power. We also modify the lockup in the converter to ensure good economy and drive abilityâ€￾.“Next thing to do is fit the stall converter with a lower diff ratio, a setup suitable for full time racers, and hold onâ€￾.

ME WANTS 1

Hmmm T5 or JMM torque convertor...........

(Still don't understand the concept of these. Will it munch a Commo off the line?)

Already booked in for August for mine

yes it should much a commo!

casper i hate u....

LOL, so telling you that is just one of a number of mods all being done at the same time would be bad???

let us know how long your auto holds up before its cooked

Hopefully the huge a** trans cooler going on at the same time should make it last a bit longer.
Otherwise, meh, needed a rebuild anyhow.

Casper mate, that should put you straight into the 14s because from memory, didnt you run something like a 15.03

Yep and yep (15.024).

Theres a few other things being done to the car at the same time, see if an unopened 14.8 is possible....thats the plan anyhow.

yes!

prick!

mm i wonder witht eh convertor i could do a 14.7....")

Won't this converter force the car to go in limp home mode in the AU's?
I heard that some other people were having problems with this?
Maximum they could go was 2800.

Its been "got around"

Interesting.

I would like to hear from anyone who gets this stall done on how the car feels around town and the track.

P.S. Casper - I will be waiting for your responce in August!
