Certainly the 'chute removes a lot of the heat soak into the tires from the brakes. Wonder if nitrogen helps race tires run cooler??

But I still wanna know how this produces 5+ HP/CI. A ProStock 500 inch engine makes 3.5HP/CI -but without boost. So how much boost? How do you keep the heads on? How big intercoolers? Spray??
Sorry-I love the tech and can't get it.

Bruce, will your NA GT touch 200? And what came with it-Goodyear F-1's?

They were probably some sort of drag tire. They won't be racing slicks.
Top Fuel dragsters are limited to "only" 500cid and they run 8,000 hp. Mind you the motors are rebuilt after every run.

For 4 seconds then a rebuild, the Ford is only 331 CID and has to stand
multiple passes on the mile with no rebuild

OK so that's 6.1 HP/CI. Please tell me how Bruce-and your GT's top speed from my other post?

This is true. And I did mention they got rebuilt after each run.

Another good example though is Poteet and Main's "Speed Demon" streamliner that runs 450mph+ at the Salt Flats. They use a blown 347 making 2200hp. They've done 404mph with a blown 289 making 1400hp.

On gasoline or fuel?

-and thanks Bruce for the Hoosiers.
