a833 trans? which low gear?
what rear gear, what launch rpm, what clutch?

just curious....

---

Stock 18 spline, 2.65 low gear. Dana out back with 4.56's and a 29" tall tire. Launch rpm was at 5400. I've been using an 11" Center Force DF for many years.

about how many passes a year would you say you make with it?

or, how many passes do you think its got on it since you had any "issues"?

"H" pattern shifter?

---

Usually do 6-7 races a year with the UMTR guys. Figure 2 time trials at each race and first round runner-up. So about 18-21 trips down the track each year.
With this past set up, (DF cover and Ram puck disc, I got about 10 runs before it started to slip. I have since gone back to a complete CFDF set up, which I ran for several years with no issues. The only reason I went with the Ram disc was because the DFX disc was on back order when I was ready for it. I changed my mind about the DFX disc due to cost if for no other reason.
Shifter is a Hurst Super Shifter 3 with reverse lock out. Yes an "H" pattern shifter.

I'm considering that CFDF clutch but I can't find an 11" 18-spline disc !!

---

Part# DF071800 for the complete assembly
Part# DF384071 for the disc only
I just bought a new assembly and used these numbers. 'Was going to use the old cover and just buy the disc, but changed my mind.

What sort of power are you putting out?

---

As stated in my sig, I've gone 11.14 @ almost 123 mph. HP calculator with a 3900+# car says that I'm making around 635 hp at the flywheel and around 545 at the back tires. With the CFDF I've pull 1.50 60' times. Most of the time I'm around 1.58, spinning the tires a bit.

I currently have a Hays "street" pp with the hays "street/strip disc". Since the motor isn't in the car yet I'd rather sort this clutch issue out now.

Thanks.

---

By the way, I've used this Hays set up that you have now. It doesn't work at our power levels.

---

Thanks for the info. One last question ... are the trowout bearings pretty much standard between the CFDF and my current Hays setup or would I have to replace that too (its brand new).

---

The short answer is "Yes". 'Slight differences in the face that touches the pressure plate,some are wider than others, but all in all they are the same.

So, I take it you're slipping the tires a bit on the launch to soften the hit on the drive line? I'm glad to see the 18-spline is living at over 600 HP.
Awesome car, btw. Love stick cars.

---

Exactly. Something has to slip at launch, either the clutch or the tires. I prefer to spin the tires a bit. With an automatic, the converter does the slipping.

personally, I like the slow left leg method to protect the drivetrain That happens as you get older (right?)

What are you trying to say??????

So I then asked about the DFX disc and they told me it would take 6-8 weeks for my order.....

This must have been earlier this year. Around April or May. That's about the time I was looking to buy a DFX disc.
