Are we talking drag engines or street engines with full boost below 4.5k, you cant have both. Think Julian is probably leading the way in the later with 879 bhp a figure that we will be chasing on Friday. The Scandys build 1.8litre 10k reving drag engines with Power approaching 1100bhp, Never seen one of those run full Power in a car . With the gas we will be approaching that 1100bhp & will be on the rollers to prove it.
