To all,
I have to give my hearty endorsement of Redline oil in a race motor
application. The #99 Red Rat Bastard 948cc vintage Sprite sees 7500 rpm+ all
race long. It sees that rpm in practice as well. My motors are generally
made of other's castaway junk. I've pl\olished a marginal nitrided crank the
last 3 rebuilds. This motor build is on its 4th season. Oil pressure remains
good. Redline seemed to cure dropping pressure when hitting the brakes hard
at Turn 1 at Blackhawk or Turn 5 at Road America. 3 years ago, I was plagued
by a head gasket problem (17 head gaskets in 6 race weekends... solved by
torquing the ARP studs to 55 lbs with a moly lube per Dave Tabor at
Comptune). The motor saw 240 to 25o degrees after the gasket would blow and
I'd be trying to finish the race. After the problem was finally fixed, we
did a leakdown test... it was amazingly good. Still haven't opened up the
motor since. (Of course you all ralize I've cursed myself for this weekend's
Vintage Grand Prix Au Grattan).
I change the oil once A SEASON! Normal race season is 6 events, so call it
24 hours + enduros of tracktime. So, it costs the same as changing dino
based oil every weekend.
Works for me.
