From the stats you just gave, it sounds like they mated 2 Suzuki Hayabusa engines together. However 11k rpms seems kinda low for that engine in a race situation.
Check out the specs http://www.radicalextremesport...c.php 1 up 5 down? thats a bike transmission. Plus looking at all the specs. That is right up there will all the hayabusa specs I want one of them engines! Throw that sucka in a miata However to get 500hp out of that engine you would need forced induction and like you said race gas. 350hp though could easily be done N/A on pump gas
