Sintered iron race clutch discussion (was: Pro Spyder intake?)

Yeah, 9 grams total. I have the exact same type of bolts and nuts in a pack with mine. I have three aluminum pairs and three brass pairs. I dare say they weigh about the same.

Sounds like you really aren't taking advantage of what this clutch configuration is for yet though. Other than just being able to hold gobs of power/torque, it gives you the ability to use low enough base pressure to allow the clutch to slip during launch (60 ft) enough to let you hook up. Then as RPM's come up it locks-up and 100% is to the wheels. That keeps you from blowing the tires and from killing drivetrain parts.

I will personally have to rely on this a lot. With the street set-up my trans will probably live. However, with the race configuration it would most assuredly die a painful death without utilizing this clutch to allow off the line slippage. Unfortunately, I don't have a Jerico and I've got a Tremec TKO behind this beast. Workable for the street config with 100% off the line lockup, but for the race config it's out of it's league.

My plan is to adjust mine so that for track duty, it will slip just enough off the line to allow me to hook with the bigger boost, keep my trans alive in the process, but once I'm moving to have 100% lock. Now, actually Mike (owner of RAM) told me some time ago that Cory Roth was running this set-up. Supposedly, he was only using 400 lbs base pressure, but then had the counterweights on also. I'd have to check old emails to find the details.
