Need a clutch for 500+ rwhp

twin disc organic probably the way you need to go. I have been reserching them, because I am in need of one my self. I tried to run a single on my 500hp/560ft# and it was either nasty engaugement or short lived. So I am leaning toward the new Mcleod. There is a 26 spline rebuilt Mcleod in the classifieds.
 
A spec stage 3 (could be wrong on the stage) would probably work fine for a street car. Im assuming you want a sprung clutch. Just depends whether you want a disc or a 4/6 puck
 
I'm switching from a Fidanza 4.3 ceramic puck clutch which is very difficult to drive on the street, it's grabs and goes with no slipping and it's very tough on the left leg) to a Fidanza 6.5 twin clutch.

Both we handle over 500 HP put the twin clutch is mush more streetable.
 
When I had my T5 and 3550, I had excellent results with my Clutch Dynamics unit. It held the power great and was very manageable on the street. You can see a little bit of the street manners at the beginning of the vid here... Twin Turbo Mustang Crisin' - Car Videos on StreetFire

They (Cutch Dynamics) are very old school and still don't have a website. They have a very good rapport with many in the turbo community. Anyways, if you are interested....do a google search. They are located in Lansing, MI.
 
All you need is the Ford Racing clutch kit. My tuner installs these on all the 03-04 Cobra's running 500-525RWHP. I actually have the stock clutch in my 03-04 Cobra which is the same part # as the Ford Racing, just 11" vs. 10.5" and I make almost 600RWHP. It holds up find. The Whipple has been on for 4,500 miles so far. I've made about 8 passes (not launching) (no powershifting) and a lot of street stuff and it is still good.
 
Stage 2+ SPEC Clutch
any experience with this clutch?
This Stage 2+ clutch will fit all 86-95 5.0L Ford Mustangs and will hold 620 lbft. of torque at the flywheel.

Stage Two Plus
These clutches are great for all moderately modified naturally aspirated and power adder engines making more torque than the Stage 2 can support. The Stage 2+ offers great daily drivability and very good wear characteristics, but provides a higher torque capacity while maintaining Stage 2 feel. The kit comes with a high clamp pressure plate, composite multi-friction carbon-Kevlar clutch disc with a high torque sprung hub and disc assembly, bearings and tool.
Price: $399.00
SALE: $359.00
 
I had the spec stage 3 for a whle put 600+ through it, nothing wrong with it. But for my street use the pedal was just way to stiff and my leg would die if i was caught in traffic.

I ended up going with a Mcleod dual disc clutch, one of the best things i have ever purchased for the car, the pedal efford is minimal to no existant and it grabs like a mO Fo. I would not even look at any other clutch in the future, this dual disc setup is def. the way to go
 
I've got a spec stage 3 and not really sure why people think they are hard to press in compared to my brothers king cobra clutch, my spec is easier. I did replace my cable, cable quadrant, add a billet adjuster and new clutch fork when I did mine though.
