185 MPH in sprint car

[VaDirt]

Not sure where to put it, other than the fact that Damion Gardner is a sprint car driver, and (normally) a sprint car is a short track racer.

USAC star and former Chili Bowl winner Damion Gardner has reached 185 MPH in a specially designed sprint car today on the Bonneville Salt Flats.

Speed Demon pushed their record for the world's fastest piston engine wheel drive car to 451.933 mph and set a new record for C/BFS at 437.183. The old record was 390 mph.

Holy small block!

Holy small block!

big block. equal spaced headers.

big block. equal spaced headers.

You sure? I read its 368 cubic inches? and(it may just be because I have nothing to scale and the turbo pipes are huge) it looks like those headers are not that big around..

Header tubes look 2-5/8". Turbo inlet @ 3.5-4 inch and turbo exhaust @ 6-8".

They probably went with a small bore and small stroke to have maximum wall thickness and minimum wall stresses- wouldn't be surprised if they're pushing 45psi or more of boost into that motor at 9-10K RPM.

368 = 3.48 crank and 4.100 piston.

Our block is rated .300 wall at 4.600, so they'd have .550 of wall at a 4.100 bore.
