"Animal Jim" has a business in my area so I gave him a call. Interesting thing is he didn't ask me hardly anything about suspension, just honed in on the clutch. Bottom line is I am going to struggle with 60' times.

Well..... I guess that answers that!

Anybody have any experience with this?

I haven't heard of these guys. But after reading about the product, it seems like others have had success with it. I'd be interested in a unbiased comparison video of 60ft and 1/8th mile times with this.

The clutch I use is RAM's most powerful dual disc street/strip clutch and it has near 3 times the torque capacity of my engine output. Apparently that was not a wise choice.

way over clutched. you'd be surprised how much pressure my new one uses, lol. base pressure can go as low as like 300lbs

The title is "Secrets of Traction on the Street" and I thought the struggle was with burning up the tires from a rolling start. What would being "over-clutched" be the problem here? Certainly you DON'T want the clutch to slip when you mash it at 30 mph do you? Seems a recipe for new clutch components in short order.
Now if you're directing your efforts to the launch at the drag strip, then, just as in a top fuel car, the clutch is designed to limit the amount of power transmitted. It will, as the vehicle accelerates, apply greater clamping force.
But how does that translate to flooring it in 2nd gear?

The topic has evolved over time. Initially when I started this thread I was roasting tires everywhere. Eventually moved away from the Nitto tire to a Mickey Thompson tire and achieved hook-up on the roll. Then it became a battle of the 60 ft time.

Every time I let the clutch out, whether off the line or shifting gears, there is an impulse that goes into the drivetrain. The upper limit of that impulse is partly based on clutch holding power. My clutch locks up quick and can hold a ridiculous amount of torque so my tires get shocked really hard. Another way to say it is that my inertia element ends up being more significant than what most people have to deal with.

let the clutch out slower then.

with your foot.

or mechanically.

or hydraulically.
