When i owned BYBYE i loved the box the only thing stopping that car from running faster was you couldn't leave the line with much boost or it would snap the intermediate shafts in the box.

but u still ran a 10.1 with it. man i wouldn't want to go any faster than that, i got kids that i wanna see grow up lol.
seriously though if i can get anywhere near 10.1 with mine i'll be in shock. great effort mate.

So what sort of power are these "hamburger with the lot" 4 speeds rated to? Trans builders in Adelaide won't do 4 speeds to handle more than 300kW, they all say they'll do a 3 speed or a powerglide...
I guess GZM in Vic. are the shop to go to?
rotamotive ran with a 13b and a jatco 4 speed
8.9 or 8.8 @150 mph
the box was dowelled for strenght and transbraked
and overdrive on a seperate switch
they are a good box if built properly
tranzmax z is a must
and put ypour oil cooler inside dry ice box inside boot or passenger floor
to keep box temps down and mph up
auto cars pick up 3-5mph with cooler transmission temps
transbrake equals heat lol

mine was a KEAS box and was rated to 350kw but my car was making 400rwkw when it ran that time and it wasnt slipping so it was a great box but they break the intermediate shafts in the 4 speeds.
11.6 at 117mph, box had the works but was rooted, no reverse no transbrake, just off the foot brake, hopeing to change that once the engine is running, have rewelded the upper control arms back into the floor so i'll try the transbrake again
Some original photos have not been recovered yet.
I think a built 4 speed would be good for the performance and what I wan out of the car. MV automatics here in Adelaide charge about $3k and rate theirs to 280kw or something.. I've sent an email to GZM for an estimate.
