clutch recomendations?
 
290/3.44 1 st gear 4speed american, alum f'wheel,4.57 gears,8.5 slicks, around 3200lbs w/ me in it
anybody recommend a single disc+pp?
flywheel is drilled for borg&beck or diaphram.
USED to be a long style that was made with b&b bolt pattern but if there is now, i ain't finding it...

Re: clutch recomendations?
 
you will have to do some research on what will fit ,,,for that ,,,is the trans a amc t-10 or a gm t-10(info from previous post),,thats a real low first gear for that trans ,,i would say if your presure plate is drilled for a borg & beck check out a ram adjustable plate and a sintered iron disc ,,more than likely you may not need a ton of base presure ,,you will have to tread lightly if you are using stock type transmissions Gmonde

2500 bucks for a 14 sec car clutch seems a bit overkill

Then please, be specific with your questions. If you can't or won't afford the best parts available for the quickest ET possible, then say so.
Autozone or Checker Auto has rebuilt clutches that are more affordable. They may not last, they probably aren't fast, but it will get you through the pits.

don't be a dick and I won't be...
thought i WAS specific, what more do you want to know?
i'm not gonna be running in the upper classes of stock OR superstock nor do i have stock in ACT clutches

gmonde is on the same plane as me, i think or at least is more realistic.
last i checked,ACT didn't have anything i could use (AMC)but i could be wrong...


besides, i could run a LUK if it had the sfi sticker on it...;)
maybe impact has a few they'd sell me....


btw,seems like the only way i'd have to worry about a heads-up race is if i'd build 2 cars...
way too many autos out there..

i recomend ram. i had a long adj. plate and a hays wheel that i sent them and they set it up with a sintered iron disc to sfi spec. it was a little over 500 complete.
hope this helps

how do you like the iron plate?
THAT's what i'm trying to decide on anyway...
that and how many "pads"...
i AM leaning toward the B&B Ram adjustable (think it's like 2200# to 2500#)...

Re: clutch recomendations?
 
no pads!!!!!! solid disc you need to have slipage Gmonde

Re: clutch recomendations?
 
makes sense, what kinda lining?
sintered iron,kevlar, organic (whatever THAT is;) )?

Re: clutch recomendations?
 
depends on whether you are plannining on using the clutch or not between gears. sintered iron if not clutching, rag if using the clutch.

well, gee, gotta use the clutch according to NHRA.....
and for the time being,this is a stone stock super t-10...
rag it is, then...


thanks for the advise, guys!

tomslick,
You can use sintered iron and use clutch on gear changes.I would redrill flywheel for long style pressure plate the ram is most economical can get adjustable long style and sintered iron disc around 700.00.(new)You'll need lower base pressure though probaly 1200# and lower.Anyone that has bridgeport style mill and knows how to use it can redrill flywheel for long style,I have even done it on vavle/guide seat machine before.
On low power car clutch is still important because if it does'nt have controlled slippage it will bog on launch and or gear changes or both.

mile is right, you can use the iron clutch if using the clutch, i just meant the rag was quicker for us driving conventionally. the sintered iron will have the very least pedal pressure.

now ya got me curious, how does disc material have any effect on pedal pressure?
btw, the least pressure adjustable plate i can find in a B&B is 2200lbs...

Call Tim Hyatt at Hyatt Racing Services at 440-254-1311. He will get you fixed up. You also need a low base pressure and that is where the low pedal pressure comes from. The clutch is what is going to save or kill your drivetrain. The 2200# is most likely an on the shelf item. Tim will set you up with something more user friendly, and can modify your flywheel too.

If you need to save money, Peter at South Bend clutch (800-988-4345) has experience with clutches for drag cars as well as diesel tow vehicles. His diesel stuff is state of the art. His street and drag clutches are conventional and not ideal for drags, but cost maybe 20% as much and he can tailor something to your car that will be pretty good, much better than off the shelf parts house stuff.

Re: clutch recomendations?
 
Disc material won't affect pedal pressure but material of disc will determine what base pressure you can run which affects pedal pressure.Sintered iron is most reliable forgiving consistent and don't cost much more if anymore but will out last everything else.I have ran a single disc in 600 hp 2900# car with base on pressure plate down as low as 300#s I was leaving line at 9600 so centrifical assisted some but did'nt have any weights added lower rpm car you could'nt get that low on pressure.BTW when you get low pressure setup make sure you use extra heavy duty return spring slightly smaller than hood hinge spring because pressure plate won't push back enough by it self with normal return spring

Tim or Rob can point you in the right direction, but for a budget set up that never ceases to amaze me try a centerforce. A customer of mine runs one in a 450hp/2900lb street strip car with a Toploader and can't kill it (he's tried), 60's in the 1.450- 460 all day. zero maintenance, changes the disc once in a while, if your not turning big RPM might be worth a look.

I have several slow V-8 stick cars. If the clutch does not slip you better have a heavy flywheel because the second the clutch grabs it will about shut the motor off. I will be willing to help you. its fun to see slower stick cars
