I went to the track yesterday, and my pos zoom clutch was slipping every run...

I have 400 hp / 458 tq, supercharged stock 350 tpi, running mickey thompson street slicks.

I want to know what a good clutch is to use with this motor that wont slip, and i also have a 530 hp 383 on the engine stand, so i want the clutch to transfer to that engine also..

Any advise? centerforce dfx? dual friction? something else?????

??? Anyone?????

How much do you want to spend, and is it a track only car or street/strip??? In my drag car, I run a McCleod Soft-lok. Very good clutch with a soft initial hit on the drive train, but it's not a street clutch at all. I've got a McCleod dual disc in a "Brand X" street car that has 440 rwhp, only had the car out a couple times so far this year but the clutch really seems to work good just as it came out of the box!!! Going to play with some counterweight changes and different material discs this summer and see how it hooks up then... Neither of these setups are cheap, but they certainly do work good. Previous clutch in the "brand X" car was a Centerforce--worked ok but didn't live too long... Cheap compared to the McCleod's, guess it depends on how much you enjoy changing clutch discs!!!!

spec 3 or 3+ clutch should do you well..........

it is a street/strip car, and i intend to put the 530 hp motor in, and would like to use the same clutch... i will look into McCleod and spec.

im just not sure. i have heard both are good.....

under 350.00 for a spec 3 clutch.................

how much hp or abuse will a spec 3 withstand? cause i will eventually throw a 383 at it...

also, where is a good spot to buy a spec clutch?

think i will be ok with a stage 3, or go 3+? also aluminum or steel flywheel????

Steel on the street, need to keep the revs up on gear changes. Aluminun wouldn't live very long on the street. Just a suggestion, but for your own safety I would make sure the flywheel and clutch are both SFI approved!!! When the cheap stuff comes apart it can cost you a foot or two!

today i was driving with my zoom 305 clutch, and started getting nervous cause it was slipping.... i was worried she was gonna explode hahhaha

They do blow up!! Friend of mine, another old racer, is missing 3 toes and has a large chunk missing from his calf from a clutch blow up... Though it happened 30 years ago, Charlie would still tell you a good clutch, flywheel, and scattershield is a wise investment!!!!

holy crap!!!!... ouch.... ya i think im going to get a centerforce dfx clutch, centerforce flywheel for my 383, and what would you guys recomend for a clutch shield/blanket?

Automatics use blankets, Manual transmissions require a scattershield, I'd recomend either Lakewood or McCleod...again, make certain it is SFI approved.

is the scatter shield just a shield or just a heavy duty bell housing?

It's a complete bellhousing with 360 degree coverage, and a steel plate that goes between the block and the bellhousing..

oooo, ok..

i use a center force dual friction

I cant decide the dual friction or the DFX, i am using a 2 step to launch, and mickey thompson street radials... so idk, i cant decide between the two..

i have a 2 step leavin at 5600 with slicks no problems with the dual friction but the dfx is alittle stronger correct? also just make sure you break it in correctly before your dumpin the clutch

Thats what jegs told me..

So what do you think tom86iroc? In the future for my 383 about 530 hp, should i go centerforce dual friction?? and a centerforce flywheel?

dualfriction or the dfx either one you really dont need a flywheel i have my stock 6 speed one unless your gonna need it for your swap later then i would get it

i have to get one because the 383 is a 2 piece rear main seal, and my current setup is a 1 piece..

I think i will give the DFX a shot. see how it does.

ok wasnt sure on the flywheel yeah i got one too for my 383 those centerforce are nice units tell me how the dfx works havent tried that setup yet wasnt out when i bought my dual friction

for sure, i hope it is good and doesnt slip, im sure it is good though... since its $399 haha...

like i said just break it nice and easy for 500 miles then you can tear into it just make sure the flywheel is clean with no oil my 6sp one was almost 600

ok, and $600? dang.

yeah the 6sp clutches are crazy money that dfx kit for my car is 700 and change lol

thats expensive. im glad i dont need one for a six speed, but i wish i had a six speed haha

lol

Hey tom86, so i bought a bunch of parts last week : ) , and i changed my mind and just went with a dual friction... haha. so we will see how it does.
