hi,
when i pull away, even if i floor the gas pedal, i can't spin the rear tyres,
is this normal,
does the rear axle stop them from spinning????
thanks,
neil

You probably to not have enough horsepower to spin them....Time to start modding the engine. If you power brake the car you may be able to get them to spin. With some exta horsepower you should be able to stomp the gas and burn them ...Catching second with an auto is fun as well :reddevil

hi,
there's no emission bits left on it,
i just thought there would have been enough power to spin them as standard,
my camaro will spin all day and chirp between every gear,
i suppose a cam, intake manifold and new carb are in order then,
that should do the trick,
thanks,
neil

What year is the car? What engine? Most of the vettes from 72 to 82 were pretty much pigs from the factory anyway..With a little Modification you should be able to get it to smoke the tires :cheers:

camaroneil

it's a 77,
air pump removed,
cat removed,
air con removed,
no spare tyre or carrier,

Don't forget your Vette squats down and has a lot more traction than your Camaro did. Wheel spin loses races............
:steering:

Jvette73

Yeah Corvettes have much more even weight distribution placing more weight on the rear tires which makes it more difficult to spin. Camaros are light in the rear and can spin wheels with far less power.

Jman

You need some power to spin your "tyres". :lolg:

LAvetteman

As mentioned above 77 in one of those years that were not known for stock horsepower. But again, your traction is a bit better than you camaro.

Tom73

Sounds as if the posi-traction is doing what it was designed to do.

It depends on what rear gear you have...

Big Fish

This should take care of the problem :jester :eek:

GrandsportC3 is right. If you want to increase acceleration, this would probably be the best place to start. Chances are you won't be spinning the tires with a 2.8:1 ratio in the rear and a mostly stock engine.

camaroneil

thanks guys,
do you think a performer intake, holley 600 vac sec and a performer cam would go ok????
thanks,
neil

also, for some reason i thought it had a 3.23 rear axle, don't why why i think that,
i thought that was the standard one for the year,

I've been wondering about that for a while... Why do our cars squat, and my F-body cars umm... stand up? Squatting seems like it would make sense, because of that whole action-reaction thing involving the car's wheels turning forward, making the differential want to turn the other way, hence lifting the front of the engine and making the rear dig in. And if that's what's happening, I can see why that would help traction.

But if squatting like that is better for traction, why are lift bars sold? Those also seem to make sense to me -- have something force the rear wheels down, but at the same time that lifts the rear, instead of making it lower like our cars seem to do.

Does the Corvette squat and the Camaro stand because of the differences in the rear? (independant vs. solid)

Jvette73

The F body cars use leaf springs in the rear right? I think thats what mainly prevents the squating. As the pinion twists upward under tq, the springs have a buckle effect that prevents squat.

Ex. is first if your ex. is stock single. See Why Exhaust is problem for HP on 75-81 -what many refer to as my Exhaust topic. http://www.corvettefaq.com/c3/ganeyexhaust.htm
Next cam, Comp XE256 or 260H for L-48 auto. Performer 2102 cam is not enough cam.
Performer 2101 intake is fine. Holley 600 is correct for that setup.
You can expect 3.08 or lower (higher numerically).

I agree with Yeller81 wheel spin losses races. Saturday I stomped the hell out of a Viper at the eighth mile drags I went too. He could not stop the tire spin. My car doesen't spin either. 1968 witn a 427 bb. I guess if you need tire spin you gotta get a Viper.

Tom73

The "squat" is a charactistic of independent rear suspension. Upon acceleration, the pinion tries to climb the ring gear. In so doing it pulls the ring gear downward. Since the independent rear has flexibility in the driveline out to the wheels, it flexes and the differential comes down. On a solid/live axle the differential cannot come down, so that force is applied to the rear springs which forces the body upward and pushes the tires into the ground. For drag racing, the solid axle is better for just this reason.

[QUOTE]Sounds as if the posi-traction is doing what it was designed to do.[QUOTE]. :iagree: Just think about how much we would all be complaining if we DIDNT have a Posi rear end. Nice smoky burnouts are indeed fun to watch, but they dont do much for 60 ft times, 0-60, and your ET. Just my additional $.02
