seems like an expensive experiment.

I tried pming spec-1 to get a weight and material make up of components but I havn't gotten a response yet.

the regular spec twin is in the 50 lb range, which is too heavy for me.

I need to get the ball rolling on my purchase, scheduled for a race in a week.

I'm thinking about going with the zoom stage 2 twin

I haven't heard anything about it, but it may be more of a road race oriented clutch much like the tilton.

It uses smaller disks for less rotating mass but the disks are not designed to take heat. prolonged slipping of the clutch in normal traffic would kill it. Lots of the corvette guys that run tilton wench their cars onto the trailer to not destroy the clutch.

If you guys are in need of a clutch give us a call we carry all of the textralia and rps clutches in stock,

there are two different versions of the clutch, one for limited street/drag and the other says limited street/road racing/yada yada.

so i guess this wouldnt be the best idea for a street/strip car? i am trying to keep the rotating mass down on my setup

You do know that a heavier mass flywheel will actually help you out while drag racing right? it will allow the motor to carry more momentum through the launch and each shift.

If this was a road racing car then you do want the lightest weight most responsive setup.

and after 2 years it's still a 50/50 split. I have had better results with steel heavier flywheels than with light ones.

The shop GTO went 10.1 full weight and with a super heavy twin disk, cant ague with results

the only time i recommend a lightweight flywheel for a drag car is when the car is severely traction limited and in that case you want to not hit the tire as hard on the launch, rare IMO. if this is a road course car then this is a different story of course
