1/4 Mile Estimation (Help me out here)
 

im buying Yet another mk3 lol, this is an 89 turbo targa 5 speed, Now apparantly this guy claims to have run a 12.57 @ like 107 or 108 or something to that effect, now this is what the car has on it,,,, 550's, lexus afm, jdm motor/tranny, stage 2 clutch/flywheel, 3" exhaust mandrel bent, no cat, no muffler, egr block off, turbo xs dual stage boost controller(@14 psi) it has a 4:11 rear in it, solid motor mounts, and there may be something else im just forgetting,,,,idk i mean i drove the car and it took off like a bat outta hell with two people in it, im just not sure if it would really run 12's, Anyone else have an opinion?

Doubt it. 12.57 at 108 doesn't really add up. Probably more like low 13's high 12's.

I ran a 13.0 @ 106mph, I'd say it's possible. I would've had to nail the launch.
