Those supra are no slouch as it has proven to make 630ish on pump gas. Not bad for just a wheel swap but it isn't enough to hang with a SC LS motor. Would've liked to see a run from a dig as roll racing is ghey but I'd rather see both on a real track
Supras have 340 RWHP & 400 RWTQ box stock...There's a tuner that puts on a catless downpipe, E50 and a tune for his 487 HP & 570 TQ and it runs 10.8 with a tune and 2 mods.
