my 62 spools faster than my factory holset IMO. im sure the ats exhaust manifold and arch flow helps also. I dont know what kind of power your lookin for bad company but i think II says the silver 62 is good til 600 hp

Ya, by the way what are the specs on the A4000 and the A5000? Im in the market to buy a large single right now. Am really looking at the silver bullet 66/74/14, was set on it tell dan at HTT said the 74 wheel puts to much load on the turbine side and is hard on bearings. Whos running the S.Bullet 66 and for how long???? Is the A5000 compairable?
