Automatic Trans On Drag Cars

[NA_R33]

Ill vouch for Mike at MV Automatics, hes done all the work to my bos and it hasnt missed a beat, making ~600hp at the crank, going to be pushing almost twice that soon... He seams to think the gearbox should handle it quite well... let u know how it goes.

I dont have a skyline but my KEAS Jatco box is going great. Paul is a top bloke and has heaps of knowledge and will help out any way he can...

Car has run a 10.48 (and a few 10.5s) off the footbrake the only thing holding the car back at the moment are those bloody axle breakages... Once thats sorted get on the transbrake and run some real numbers.

There are quite a few keas Jatco boxes running 9's...

I have a Jatco 3speed in my RB20 powered Valiant Ute.

Has a 5000RPM stall speed converter, TransBrake, high flow fluid mods, and all the extra clutches. Good for 600BHP.

If I wanted to stengthen the box at all I'd need to get a Titanium input shaft made up ($500 bucks odd).

They are identical to a Chrysler Torqueflight/Ford C4, but the machine work and material quality is far better (Jap built).

For 900 HP, it will work, it's small and light and has 3 gears.
