I am working on a project P3 28 for drag racing applications...this motor will be run in a 2.5 lb dragster using 50% nitro and a custom boat pipe... the car will run in the 1.4-1.5 second range at about 100 MPH in 120 feet....I am still working ont he sleeve and case, but here is the final pics of the crank ( I may do a little more weight reduction yet tho ).. the crank has been massively lightened and timed to the moon, so its no longer usable for offroad ...
