Default Dragster diff

G`day folks
I` in the planning stages of building a front engined dragster and have hit a brick wall. What diffs have you guys used in large scale dragsters?
Is a solid axle preferable to a diff or vica versa? I cantfinish designing the rear end of the frame until i know what diff i`m going to use. I`m on a pension so i cant afford to buy a $600 diff but i have a lathe and mill so can make a basic diff myself.
Cheers all
Troppo

Mate have you looked at the toro diffs from self propelled mowers? or is it easier to just make a sprocket on a solid shaft?

Yeah, looking at sprockets for a solid shaft, got a pit bike with a 3:1 reduction which should give me plenty of torque so should be able to run a 3:1 final drive. Looking at modifying a car aircon compressor clutch as a final drive clutch, allow me to run top revs and dump the clutch on the line

Mate have a look at these

https://www.keb.de/en/products/magne...nd-brakes.html

I don't know if they do 12V clutches

A lot of my machines use the DC 24V clutches..... a lot smaller than a car AC clutch, however the downside is you'd need 24 v supply.
In saying that, they MAY have a 12v version.
I never bothered to have a look, just that KEB make clutch/brakes for industrial machines with 24V control voltage.

Lemme know if you find a 12v version, or if I just gave you a bum steer.
Cheers, Mudgy

Thanks for the link mate, looking at it now.
Looks like they are all 24v. i was worried about they added weight of a 12v battery, 24v would kill it
