Engines are designed by Renault, made by Mecachrome and limited to 10k RPMs. . . it sounds like more. I am trying to figure out why they sound so amazing though! It has an 8 into 1 exhaust, which might explain why it doesn't sound like the F1 V8s? Maybe there is more?

Anyone have any info on the crankshaft? I googled for a little bit and couldn't find anything. . . maybe it is a crossplane crank.
