Eldon is a great guy, and an old Grand National drag racer from back in the day. He drove over from Indiana and dropped his ATS-V off for another round of upgrades. He had already run the equivalent of a 10.03 quarter mile at full weight with his Purple Belt mods, making 596 whp. We added Caddy Issues turbochargers, Mace Stage 1 camshafts and valve springs, ARP head studs and Tapout intake. On the dyno and Eldon’s car put down a beautiful powerband peaking at 713 whp.
