Hello,
Yes it's our Sunbeam (norris motorsport), its a rather long spec list so Ill just give you an engine bay shot rather than type it all out. Engine is one of our short stoke high revvers (up to 10,000rpm).
We were running around 500bhp on Sunday, (low boost) though it can run up to 750bhp at maximum boost. If you are coming to TOTB on Sunday you can get to see it run at full power. (except on the handling course where we run at minimum power! LOL)
