Chris from North Carolina dropped his ATS-V off at our place for installation of our Purple Belt Performance Package, plus Turbobay turbochargers and our Stage 2 valve springs, retainers and camshafts. Peak numbers were 638 whp and 626 wtq using SAE correction factor. Most people would be satisfied with these numbers, but not Chris. He asked what we could do to get his numbers into the stratosphere above 700. We recommended Caddy Issues turbochargers and he gave us the green light. So we swapped turbos and strapped the car back to the dyno. The car never even left our shop. With the same tank of E60 fuel, the same WGDC and on the same dyno, Chris’ ATS-V picked up 100 whp in the meat of the powerband at 5,500 rpm!
There is a big difference in the level of engineering and component quality here at Tapout. This is why we hold more dyno horsepower, quarter-mile, eighth-mile and 60 to 130 mph records than all our competitors combined. And this is why you want to be careful not to fall for the schtick of what some others say when they provide no data to back up their claims.
