The standard set-up with the correctly matched engine on 4 x greys OR 8 x greens could achieve this, so if this is your power ceiling, you are wasting your money by wanting to fit an RS500 set-up, when you have something that will already do the job...

Any of the Cosworth ECUs (if correctly mapped) can achieve this power. Obviously the 8-injector boards to suit (if you haven't already got one) are EXTREMELY expensive (circa £750).
