Due to the extremely small group that race 4 speeds, I just want to see what your setup is.

Looking for setups that have a A-833 4 speed
Stock Syncros (not a crash box).

Are you powershifting each gear? What RPM? 23 or 18 spline
What fluid are you using? How much fluid?
What type of clutch?
What weight?
What RPM are you launching at?
Tires spinning at the line or clutch slipping?

I'm leaving around 6,000 with a 23 spline 2.65 1st gear.
Shift around 6,200
Traps around 6,400
Tires spin, clutch is a dual disc McLeod RST (doesn't slip)
Weight about 3400 with me in it
Powershift all gears
Fluid is currently Passon Lube 4 quarts plus a little more to get it up just below the fill plug
