Chris,
Yes, they really did go 140 mph, without a tail wind. The wind was actually cross/cross head.

Both of the '08 Mustangs at Ennis were SS/AA cars, with C-4's built by Len Schneider, a West Coast transmission/converter builder in Grass Valley, CA. The manual-transmission cars might go even faster; dunno...

Just wait until someone actually blueprints one of them.

Craig,

I don't know whether NHRA has a handle on the drive pulley and blower pulley sizes, but if they don't, "blueprinting" will pale beside what additional boost from overdriving the blower can do for engine output.

Boost is addictive!!!

Bruce,
My ancient (yellowed) Moroso slide rule "Power/Speed Calculator 89650" says 730 HP at 140 mph for 3,485 pounds.

I don't think ANY of these calculators are dead-on accurate; too many variables, but they do give a ballpark figure that is good for discussion, I think. That additional (100+ pounds I added) weight was in deference to someone who said that's what they actually weighed at Ennis.

Bill,
My new Moroso has the number at 745 ish. I think all the calculators are within 1% to 2%.
