MC sizing and actual pressures

[Skip Fix]

So the first attempted drag track outing last month on the 500" Pontiac motor/Camaro the Strange /Mopar MC just would not get enough hold for the line lock to hold the car for a burn out. Crappy track we left after two 1/8 passes. Also brakes did not slow the car as much as I would have liked at the top end, 102 in the 1/8th with a SLOW 60 ft, but brakes probably not completely bedded in yet also.

It always took a lot of leg pressure to build pressure max pressure on front and rear gauges after master were maybe 700psi. The MC was a 1 1/8" I had bought years ago. Today swapped on a Mopar style 21mm(7/8"), stayed Mopar style as the pushrod and Heim I had set up for the first one would swap on. Wow it can make 1100psi with the same leg pressure! Heck 700 just with my arm. It does have a moderate amount of increased travel. I'm going to give this one a try next outing(if it ever stops raining have had 3 rain outs in the past 2 months and some rain today) if the travel is just too much there is a 24mm(about .94") I'll try.
