about one year ago i wanted to go with a mid power fast spooling setup, so i took the car to buschur's and went with a br 2.3 stroker, stg3 head, fp-red, brand new 5sp swap and exedy twin. when i picked the car up i was super happy cause the car feels great and is crazy fast on 93oct!

i put less then 4k miles on this setup and i want to change things up a bit and shoot for more power with high boost and e85, im going with a br forward facing hta86 1.03 a/r turbo kit and few other mods but my problem is i just put in a exedy twin $2k clutch thats been babied for less then 4k miles.

should i keep the twin and hope for the best? or do i have to pull the trans and convert the twin to a triple cause the twin wont hold 600 on a mustang dyno

the car will not be a drag car and will not be launched! need some advice on this please

Is it a HD twin or standard?

The HD is good to about 600ft/lbs of torque, You should be okay on your setup

 

your headed to triple territory

with over 475 ft/tq launches will KILL the exedy twin HD... fast

 

oh sry i forgot to add that it is a exedy twin HD but i thought it was rated 535 at the flywheel?

do you think if the car is not launched it will last? i would really hate for it to die on the dyno while being tuned with the new setup!

 

You should be okay on the twin

 

if you launch it, then you're gunna see issues. i know you said you won't, but i wanted to throw it out there.

 

I just installed the Exedy Twin HD in my Evo VIII. I spoke to Exedy last week on how far I could go with it and they said that clutch was good to 615 torque at the wheels.

 

They rate the numbers at the crank. There is no way a twin will handle 615 wtq

 

Just telling you what Exedy said over the phone.

 

ok i think ill stick with the twin for now cause i dont really have money to throw away like that unless i really need it. Thanks for the help guys!!

 

You can sell your twin and upgrade for a reasonable price, that way you have piece of mind.

 

i dont know where I got this.. so dont ask haha.. i just know ive had it for a while now

 

you can convert to the triple for $950 or less.

i can tell you in MY experience at 530wtq, my BRAND NEW twin lasted maybe 6 launches. my traps went from kept getting slower and slower.

switched to the triple and my first past outdid my previous best trap by 2 or 3 mph and my ET by .3 seconds in the 1/8th mile

so i would say, you can stick with the twin if you don't plan on launching at all...but have a triple fund set aside for when the time comes

 

they gave you some bad info it will not hold that much.

 

i had the same experience, at less tq even. The twin is being converted to a triple on Tuesday.


seems pretty accurate on the twin section for drag racing from my experience. clutch was a dream on the street, but couldn't take many launches.
