I know this might or might not be helpful to you....
The S2SmartsRacing Brab uses original profile cams....
and the firm that rebuilt the engine runs the same spec
engine in a Colt CZT that is used on track days and sprints
purely for fun by the boss of the firm but mapped 'higher',
and that punches out a tad under 450bhp.
(Both cars use forged engines with bigger turbo's, exhausts
etc etc, as well as standalone ECU's due to the limitations of
the tables in the standard ECU.)
Changing cams to one's with higher lift profiles or with more
overlap works fine on normally aspirated engines, but with
turbo's it is an entirely different ball game as there are a lot
more variables that have to be taken into consideration.
If there were other cams that were better suited, then the firm
that did Rob's engine would have used them in the Racing Brab,
but I think I am 100% correct in saying that it runs standard cams.
(I'll double check and amend this post if I find out that I'm wrong)
I'm not sure why you're asking about cams, but if it's as a way to
getting more power from your own engine; after fitting a hybrid/larger
turbo etc etc; then the first thing I'd go for is a 'piggy back' ECU to get
over the limitations of the standard ECU.
(standalone ECU's are only suitable for race applications as they cannot
control euqipment like the EPS etc that are CANbus controlled.)
