Im not aware of any road going LET with anything like this power yet, although some of the norwegian lads have managed it on there track motors over there.

Very hard to find much info out about them though, its FAR harder than trying to bolt together my YB to make 600bhp in reality as that is relatively common compared to 500bhp from a LET, just to put it in perspective.

End of the day though, all engines are just air pumps and work much the same way, i just have to make up for a few short comings that the LET has (like no piston cooling to begin with) and i should get there in the end
