From Stock to 8s
A Carbon Fiber Track Pack 2020 GT500 turned into one of the fastest DCT GT500s in the country. Factory Eaton out, Whipple 3.8L in, 1,122 rwhp on a Lund Racing E85 tune, and an 8.86 at 163 on the stock dual-clutch.
From stock to 8s
What started as a factory-fresh CFTP escalated into a full-blown horsepower warhorse. The heartbeat: a Whipple 3.8L supercharger fed by a triple-pump return-style fuel system from DivisionX and Lethal, all tuned to perfection by Lund Racing. On a Mustang Dyno it laid down over 1,120 rwhp, then backed it up at the track with an 8-second pass, making it one of the fastest DCT GT500s in the country.
This build is a full look at how we take a platform with potential and push it well past the factory's imagination. Below is the full mod list, dyno results, track data, and a playlist documenting every step. Whether you're chasing 1000+ hp or just want to know what it takes to run 8s in a DCT GT500, this is your launch pad.

See exactly how we turned a bone-stock Carbon Fiber Track Pack GT500 into an 8-second monster. This playlist covers every step, from first mods and dyno runs to fueling upgrades, the Whipple install, and full track shakedowns. Planning your own Predator build or just want to watch one get pushed to its limits, the series delivers.
Whipple's 3.8L Gen 5 twin-screw supercharger, paired with a 2.75-inch GripTec upper pulley for maximum boost and belt grip under load. It's one of the largest blower options for the GT500 Predator platform.
On Lund Racing's custom E85 tune, this GT500 put down over 1,120 rwhp and 844 rwtq on a Mustang Dyno. That pushed it to an 8.86-second quarter mile at 163 mph.
A full Lethal Performance / DivisionX triple-pump return-style fuel system built around "The Box," our fuel hat system, good for well over 1,500 hp on E85.
Yes. The stock Tremec TR-9070 DCT is untouched internally. With proper tuning and supporting mods, the factory dual-clutch handles over 1,100 rwhp reliably, though we optimized launch strategy and datalogging through Lund Racing.
Stainless Works longtube headers into a Corsa Performance double X-pipe catback. It keeps flow high and backpressure low while delivering that signature Whipple whistle and Predator bark.
We took a factory-supercharged GT500 past 1,120 rwhp and into the 8s with a Whipple swap, the right fuel system, and a Lund tune. Tell us your platform and power target and we'll spec the kit, fueling, and supporting parts to get you there.
