Any chance it could be true?

There are a few running 500-600 rwhp on stock internals in the U.S. Thats using Race fuel ofcourse.

 

Its all about how long it will last though.

just for arguments sake, dont US dynos give a larger reading than europe/japanese dynos though?

Technically..no they should'nt. Although thats a big debate and cars with similar modifications definatly make more power than we get here, but then a lot of that is becuase they often use Race fuel on the dyno and quite a lot do have impressive 1/4 mile times too.

ah, thanks for that mate!:cool::duffer:

imo dynos are a joke iv messed with my mates and for a laugh we took almost non of the power loss vairables in so my c20xe calibra read 44bhp - so that was what was actually getting on the road - and if you put more vairables in we got 235bh, i sold it with a dyno test certificate that read '175bh' - there 150 standard and like i said its all shite
