Gearing for supercharged Camaro

Postby utahchargerzz » Mon Jan 01, 2007 2:24 am

Tiffany is moving up this year. We have picked up a
1990 Camaro,supercharged and F/Injected. 383 stroker w/ Dedenbear glide,
15 inch street radials. This car is putting 600 hp to the rears.
Currently has 3:70 gears, seems low to me any ideas as to what we should be running? smiley-help

Sorry we didn't see this sooner, but most people I know with a setup like that are running 4.10.

I don't have any experience with this kind of set up, however people that I know who are running bigger blowers like 8, 10, & 14-71s are typically running a faster gear than what you'd expect.
A friend of mine has a 14-71 on 468"BBC in a 10.5' street shoot out type corvette @3500lbs that goes 7.80s, with a 3.55 gear.
I know it probably doesn't have much in common with your car, my point was with the torque that a good blower makes you don't need a very deep gear at all. If it already has a 3.70 maybe you want to try it before changing to a deeper gear?

Thanks Steve , I was just thinking the same thing!
The blower, doesn't make the difference,
just the amount of boost! This car is setup to over boost all the time.
It is controlled by the blowoff valves, 2 of them and big ones at that,
this thing comes out of the hole instantly.
I've never run a supercharger before, just trying to get a incling of what
I'm doing.
Any more input would be appreciated!
Thanks again Steve.....Dan

i defintly agree with steve on this one. a supercharged motor has a ton of torque right out of the hole. even when i had my bonneville SSEi, without slicks on it, it would smoke the tires 90' down the track.
try what you have first and see what it does for you.

i thought for sure i would be seeing tiff on a factory harley this year smiley-cool
