 No clutch news anymore?

As i switched to an new engine, and had to make a new flywheel,

why not a  new clutch also?

After a lot of problems its working now.

All this talk about custom clutches.. 

My stage 4 + thick Black Magic (and CMS) went 1.441 60-foot at SCC2016. Full steel car. 215/65-15 DOT's.

No need to make it custom or difficult

It will be when you want to go fast   and I thought you had day moulding wings on that car?

Thats probably why he wenter 0.07 faster ... :-D

[Typ3racing]

The goal is to reach 1.3.. 

With 2500lbs car(and driver)
1.7l Turbo engine.

IMHO its better to have more rotating mass to get the car launch properly.
In comparison to the Subaru/AP Clutch-flywheel crankshaft assembly now i got 15kg more weigt.

[Basti]

15 kg???

[Typ3racing]

15 kg???

Yes.

+8kg Crankshaft
+7kg Clutch/Flywheel

Ok. Heavy steel car but day mouldings.. and a heavy steel 6-point cage. And real glass!

I even have a roof!

 I have a roof on my 67 to, similar car to yours as well    only went 1.45 60ft though, maybe with some C/M it will go quicker

1,45!!! That's slow man 

[richie]

1,45!!! That's slow man 

Yep but ok for a cable and no tricks or fancy stuff like C/M  , and still went 10.42 so something works

You should bring the white car to SCC! Then we could have a big power adder '67 matchup!

Torgeir, you and me. Closest one to 9.99 wins a cup of tea?

So if I go 9.80 and you run 10.05 you win? doesn't seem right   Wont be this year as Drag week will take all my budget up

[Jyrki]

So it must be the fiberglass that makes all the difference 
My old '65 street car with fiberglass body parts ran a best of 1.29 on dot tires, stage 3 + black magic. The chassis car has a tricky clutch and real slicks, but is slower to 60ft. BUT it is 100% steel

  Very good 60ft for DOTs on your old car, this year your steel car should 60ft better than that though

Hi clutch experts 

Want to use the McLeod 8" clutch cover with B/M Disc for my 3.0 Pauter (hoping for 300hp  ).

For the clutch setup i have a steel pressure ring made by Pauter and a aluminum ring (Picture) here. Which one would you use, some experience with distortion on the light one?


Thanks for helping!
Stefan

[Airspeed]

I think a steel (rubbing) ring is usually used, in order to use an alu flywheel (not the other way around?)?

My recent update with two new and mostly thicker plates, which meant I could remove my steel ring alltogether (hence the small holes where the attachment screws were):

[bedjo78]

what dual discs ? where you bought them ?

[Airspeed]

what dual discs ? where you bought them ?

Tilton.
As I use a G50 transmission, which has the same spline as Mendeola, these have 23x 1" spline.
Bought in the US online at one of the big race part shops, forgot the name atm, but will post it later for you

[Eddie DVK]

Airspeed, that is a very light flywheel  is it a 200m?

[Airspeed]

4,2kg; its a chinese chro-mo 200mm version, but the disks are only 177mm outer diameter (inch size converted), but the inside minimum diameter of the disks exactly fits the 200mm parth of these flywheels, which is pretty lucky/briljant if you ask me :-)

Hi volks...

Found a nice video of a TF clutch...
enjoy ....

Servus Martin,

looks good.
Do you use still the single clutch on your setup ?

Hi Stefan...

Yep still single disc setup.... even more... to keep the package tight and light it is a double disc  (6,5mm thick) used as a single disc...
Although higher launch RPM +9000.... is causing significantly more wear.... especially on unprepared tracks like Zerbst, where I had to slipp the clutch 1.52s on the last run.....

Hi
The thing about the clutch on an NA car is more sensitive
Than on a car that has a boost
If you are going to use the clutch Infon in a VW, you should look at prostock what they do with it
After being C C in prostock (v8) (promod) o love Vw (pro stock about 1500 hp o 1066kg) When we started to use that knowledge in a NA vw the numbers went down to 60 and Et
What we started to do was go there with a heavy flywheel because the power on the engine is not enough to use the slip in the clutch
We went from 1.44 to 1.38 then with a lot of adjustment we were down to 1.34
Since you measure your slip pressure on the clutch, it is very important
Uploads a film of how we work with clutch in the prostock world
Seeing Topfuel is not right because you have too much effect so you remove type 8000hp on the starting line in the clutch Same with promod where we can remove 2000 hp in the clutch

This!
You either go with a really light combo (aluminum flywheel+steel friction surface) on a true CENTRIFUGAL clutch, like the prostock ones, or you go with a heavier flywheel on a conventional setup.
This will give you more momentum and really help to launch. You can even start leaving with a lower RPM to take it easy on the tranny and everything else.
