Highest speeds two-up

In Rat Racing, we discovered fairly early on that Fast Rats above 140 mph couldn't be flown 3-up. I think that the Big Block crowd reacted to the large power jump between a Mark VI and a Nelson with bigger planes, not faster ones, because 120 mph times two, for 240 mph closing speeds, was the max that normal human reflexes could handle.

We could fly as fast as 120 with small planes in the late 1960s, early 1970s, and did the same thing when Fox's Mark IIIs and IVs came along in the 70's, increased the sizes of the planes. I flew a "Fast Phantom" on a Mark IV in the late 1980s at 121 mph, and it was screwing me down into the ground any time I leveled it out.

I wasn't interested in flying that one two-up. Anyway, match the planes Jeff sells to a Pylon Racing engine (40s), and those will fly the way you want, I'll bet (read about the Sonic Chicken Fast at Thompson's NW area newletter's web site).
