It depends on how you launch. I've heard of people snapping output shafts on drag radials with SPEC clutches. Obviously a dead hook launch is going to be rough on your driveline. If you don't already have an aftermarket rear 9"/12 bolt and aftermarket U-joints and driveshaft (with loops of course) I'd reccommend it.

 

The reason I ended my post with search for scientific reasoning (ie Dyno ot ET) was because all I had was SOTP back up. I am glad to hear that its more appropriate to have a steel unit for drag racing becuase thats all I'm really interested in. And I glad to hear that your times remained the same or got better? You said your trap speed remained unchanged. I felt as though I may have made a mistake not getting the al. fw thats all. I will check out the thread you guys are referring to.

FWIW, I don't think having an aluminum flywheel will hurt drag racing. You just may have to dump the clutch at a higher RPM.

I have no problem melting the tires from a standing start in 1st gear with my aluminum FW, on my stock motor N/A. Same from a roll into 2nd on the nitrous (or even N/A depending on conditions).

The inertia argument is no doubt correct, but in practice, I don't think you'll notice it if you adjust your driving appropriately.

I think that any weight you can shave off the front-end, especially connected to the driveline, is generally best for drag-racing. My 0.02.

 

When installed right, and I mean, no flaws afterwards, the Street Twin is a great clutch. I love mine, and I wouldn't go back to anything I've tried in the past.
I just love it!

PS: I do have the steel flywheel. Works just fine, I haven't been able to spot any negative about having it, as supposed to having an aluminum one instead. I'm sure having the aluminum one has its advantages, the way I look at it, I don't know if it would make me any happier over the way it is right now.

 

Do you guys recommend getting a new slave cylinder?

Its pretty much on/off clutch? No letting it out slow, once it grabs, ur going? Hows that work for reverse then?

i should be fine with the drivetrain as long as i stay on street tires right?

 

and can you bleed the system out of the car or must it be installed to bleed?

Once the car is going, is the chance of parts breaking greatly decreased? IE, if i do an easy start then punch it and go hard.
