Just for something new. I'll post this for Buster as I don't think he comes here too often.

It sounds like Jose short shifting on the 3/4 to me.

other than that he needs to get that ******* almost 70lb stock clutch out of that thing so it can accelerate.

The only major differences, from before, it seems are he was running open headers & he put a 3.91 gear in. As he's done, in fourth, right at about 130mph.

Good races. Do gears and mop them up Rick

Lol. If it was just going to 130 no need to 3-4 shift.

Those ******* things weigh 70lbs? Holy ****.

Almost...66 or 68 lb. It's retarded. I've pretty much concluded that gm does it as a way of mechanical torque management.

That's wild, my entire clutch/flywheel setup is in the low 30s. Excited to beat on it once I replace my wobbly worn balancer.

They do it for drivability.

No.....they do it to help control the massive tq.

ex1- 4cyl hondas have about a 30lb clutch stock.

ex2- mustangs have about a 40lb clutch stock
I don't see anyone complaining about drivability in either of those vehicles with much much less off idle power available.


Now the argument could be made for nvh improvements. But from my experience of setting up my own very light clutch and us putting the same set up in a 5gen/c6 that's bogus to.

which relates to drivability...

Controlling massive tq is only a way of tq management.

Drivability would be how the clutch applies.

snake95

I understand the drivability thing to a certain degree but 66-68lbs is heavy as ****. Like heavier than aluminum heads heavy.

Lots of things control drivability of a clutch. The material it's made of, length of the clutch pedal assembly, fulcrum of clutch vs master, size of master, hydraulic release bearing face/diameter, weight to some extent w/o being absurdly heavy, the engine idle tune .....and probably a couple other things.

Yes and no. The initial hit of the stored energy yes.....but they likely pull timing and/or throttle position to control that. Why do you thing they advertise nls? It's not to make it faster......it's because they control the tq by managing the shift and thus reliability. W/o slipping the clutch into the next gear or controlling the inertia from it that heavy *** clutch is only holding the engine back.

Wtf do you know about me making sense and a stick car? Took a auto to get you to the track.
