My guess is that it's minimal. Considering that the rotating weight savings gained by installing a lightweight flywheel is probably ten times the weight savings of all those underdrive pulleys.

Haibeck claims that a light flywheel gains about 15 "dynamic" horsepower, so even when you take the "underdrive" aspect into account I would be surprised if you gained as much as 3 or 4 h.p. with the pulleys.

But those little things add up. Witness all of Pete's efforts tweaking the stock block 350. All those small improvements add up to some *** kicking power, instead of just opening your wallet to buy a whole new bottom end with big bore, and a stroker crank.

That's why it would be great if Pete would put the car on a diet and tweak the suspension to get those 60ft. times down. A ten second stock block ZR1 would be phenominal.
