2015 C7 Z06 Corvette I built for a customer for Speedweek at Bonneville. Targeting 300mph requires a heap of grunt and we've got it. Twin turbo LSX built by with up to 2000hp if required. Holinger RD6 paddle shift sequential box. Huge turbos hanging in the front bumper as they can't fit anywhere else. Trust me, I tried. Three massive ice tanks fill the passenger area to cool the intercooler, engine coolant, engine oil and fuel. The car is full of lead to give it grip on the salt. Final weight is nearly 4000kg. Chrome moly funny car style roll cage. All work carried out by me at Top Gear Autotech. Kerry Holland +6421797635
