306 supercharged only runs 12's at 120mph

[S10V8]

Shouldn't an 89 mustange hatch with 3.55's, 27" slicks a trans brake with 4500 stall converter that had apparently 600hp run faster than a 12 at 120mph? It was a 306 with a charger.

maybe it can help you out.

I know some one who got a 90 hatchback, /supercharged with 600 hp he was running 12,22 at 118 on street tire. i dont have to say that he had ZERO traction..

with 302 Ho for base.

Depending on the weight of the car and altitude. Also there a lot of other factors to decide if the car was setup perfect for that combo......sounds like it wasn't.

So what you are saying is that this guy had a lemon of a setup? Because it had slicks.

he blew this motor up, so now he is supercharging a crate 500" big block, I think a 514 or something. what sort of power would that thing make?

His car weighed in at 3176 I believe, my s10 weighed in at 3007 with iron heads and a 350 right after him.

There is a lot more to going fast than just HP. There is the torque curve, amound of torque, the gearing, the transmission, the differential, driver, and how the suspension plants the power, as well as how the tires stick.

You should be in the low 11's with that MPH.

You should be in the low 11's with that MPH.

I'd say tapping on the 10's back door.

Dunno, I know a guy with a highly modified '99 Cobra with a Procharger who launched at 6K and ran 11.4 @ 121... So yeah, low 11s if the car has a good driver...

That guy was putting down a little over 500 RWHP...

If he blew it up, it probably leaned out and was not living up to its potential. Just a guess but he may not have had enough fuel system.

Depending on the weight of the car and altitude.

Altitude has little/no effect on a supercharged car. Rather than relying on a vacuum as a pressure differential, the supercharger has pressure forcing air into the cylinders.
