Video: Quickest Stock Bottom End ZR1 Uses Mahle Motorsport Pistons
Eric Lancaster has been on a quest to put his supercharged ZR1 into the eight-second zone, and this past Friday, November 15th, he did just that during a session at Maryland International Raceway.
His first pass of the day resulted in a 9.30 at 151 MPH, just a harbinger of things to come as the day would progress. Not only did he eventually turn in the quickest and fastest stock-bottom-end ZR1 pass ever of 8.92 at 156.25 MPH, he became the first ZR1 into the eight-second zone, all while shifting gears like a madman, blowing flames out the quad tips on nearly every shift in the process.
This awesome car relies on a number of go-fast parts to achieve the feat, namely a set of stock Mahle Motorsports pistons, which are but one of the many high quality parts that GM has stuffed their Gen IV LS engines with to make them capable of taking this kind of punishment.
Atop the short block is a set of Brian Tooley Racing LS9 ported heads with BTR springs and a BTR Stage III camshaft. In the power-adder department, Lancaster has set the car up with a Lingenfelter supercharger snout using a 2.6-inch pulley, a Lingenfelter 14% overdrive harmonic damper (which helps to drive the supercharger harder, along with the smaller snout pulley), and a set of American Racing Headers long-tube pipes.
Believe it or not, this car is also still running the independent rear suspension, and although it’s not as quick as Mark Carlyle’s six-second drag stormer, it’s still street-driven on a regular basis. An incredible achievement for Lancaster – our hat’s off to ya!
