That's only with Shell Racing A which has 3% acetone but they only sell it in their own new drums so that adds to the purchase price. All other brands (mainly BP) are sold from bulk and are straight...

RE: *** CLUB SUPER TIGRE ***

Take an ordinary crankshaft with the usual cutaways for balance. It's roughly 1.25" diameter so 4" circumference. That's 1/3 feet. At 15,000 revs the "tip" speed of that crank is just under 60 mph....
