hey guys, as most of you know, i've been running a ACT stage 1 5sfe clutch since i swapped in arts motor back in the day, it has performed great for me over the past few years, with no issues, however, its starting to get some miles on it, and since i have been over the torque rating pretty much since the day i turboed, i cant expect it to last forever.
the problem begins with the fact that even the higher rated ACT clutches (and most 5s clutches for that matter) is that theyre only rated for 350ftlbs at the flywheel, and with 275ftlbs at the wheels, im pretty close to being over even THAT rating.


so after a bit of research, i came up with this info.

the 3sgte friction surface area is 236mm, the 5s is 225mm.
the stock 185 flywheel will not bolt to a 5sfe crank, without elongating the bolt holes a fraction of an inch. guys who build strokers with the 5s crank run into this problem.

the solution can be had in a few ways, either elongate the bolt holes on the 185 flywheel, or use a st-165 flywheel, which will bolt to the 5s crank, however the friction surface is 225mm, like the 5s, which i am trying to get away from.
the fidanza light weight flyhweel for the 3sgte has elongated bolt holes from the factory, specificly for the stroker guys, who use the 5s crank.

SO, what i am going to do, is use the fidanza 3s LW flywheel, 3sgte pressure plate and disk, and the disk will have the s54 spline count.

ACT makes a disk for just this application, and has a part # available for it.

here is a list of the parts that are needed, this list will work for 5sfte guys that are looking for 300+ftlbs at the wheels, as well as 3sgte swap guys that want to use the S54 (stock GT) transmission.

it is a 6 puck, sprung hub disk, with theyre heavy duty pressure plate, rated at 499 ftlbs. at the flywheel. (theyre street disk is rated for 350ftlbs, they dont do that with the 5s spline)

for the 5sfte and 5s based stroker guys, you need a st-165 flywheel, or fidanza lightweight flywheel for the 3sgte (swap guys, the flywheel is an option)

ACT pressure plate PT # TO23
ACT 6 puck sprung disk PT# 6236216
i always recommend a OEM throwout bearing, but the ACT PT# is
ACT throw out bearing PT# RB442
ACT alignment tool PT# AT17

ill post pics of the flywheel when it comes in, it should be here monday, for now, here are a couple of pics of the clutch setup (this is jims clutch, but it is the same disk and pressure plate, just diffrent spline count.)



ignore the spec disk, ill edit in an actual pic of my disk when it gets here.



woot for 500ftlbs worth of clutch!

I think you would be just fine with a normal 5sfe 6puck. Even though there is a bit of less friction surface, those 6pucks can hold almost anything you throw at them. It would still be a huge upgrade from what you have in there now.

yea, it prolly would have for a while at these power levels, but this way im ready for future upgrades i plan on making, and when i switch out to the E153, all i need is a disk.
and the best part is pedal feel is virtually the same as what we have now.

I dig.

yeah i could have told you this, i have the ST165 flywheel in my stroke 3S-GTE in my All-Trac. i had Southbend clutch build me a clutch just for it. i sent them the flywheel and they made me a 6 puck kit to match.

I have an st185 3sgte lightweight flywheel in mine with ARP bolt kit and used together with a 5sfe stage 1 clutch.

not posting it because i didnt know, i just posted up the info so that its here for everyone else
thanks for the contributions tho, if you have part #s and stuff that would be great, maybe we could get a sticky with all the diffrent setups available in one thread.

good idea, ill hit up southbend and get part #s

No where in any gen clubs can you find a place like 6gc where information is great. Stickies and loads of information and how to's and etc., I don't see this in other gen sites. I know I've said this many times before. and keep up the motivation Manny - good job.

WOOT flywheel came in just now!
got a great deal on it too, 269, shipped.
sometimes, ebay really does has your IT.






this pic showes the elongated bolt holes for the 5sfe crank.



clutch will be ordered later this week.

It's actually a 3SGTE clutch, with a 5S hub

Our Competition Clutch 3SGTE flywheels fit the 5SFE with the right bolts, as trdproven mentioned

-Doc

actually newcelica.org for the 7th gen is very informative. it dosent hurt that i wrote most of the information there ok maybe not most, but alot

So other than Gear Ratios, why would you switch to the e153 if the s54 can handle 500ftlb with this setup? Sorry if this Q? is stupid.

i dont know that the s54 can handle 500ftlbs...i can garantee you the axles wont, at the minimum.
i just needed more clutch than i had, and the next step was either a 350ftlb rated 5s clutch, or this setup, or somthing even more extreme in a 5s setup, which i didnt want to do.

as a sidenote, i ended up ordering a competition clutch kit from tweak, same 6puck sprung hub type, for ~ 100$ less than the ACT.
pics to come when it arrives.

so the competition clutch stage 4 hybrid clutch kit arrived yesterday, as promised by tweak.

thanks tweak, i appreciate the quick response, and shipping. saving me 100$+ is also a major bonus!

so, on to the pics!

pressure plate side of the disk..i dont think the springs will be poping out of this side..lmao..
also, it has a dual spring design much like the ACT 6 puck disk has (its more noticeable in the opened pics):



flywheel side:



pressure plate friction surface:



clutch disk on flywheel:



and pressure plate over top of that:



im going out to the garage in a bit to prep up for the install.

pics of the install later today!

sexy, keep the pics coming

can u post me a link where i can get this clutch kit

i got it from drtweak here on the board. http://www.phoenixtuning.com/

Manny - I have a LW flywheel from an st185 and used ARP bolt kit with 5sfe clutch kit and pressure plate. How would this relate to your topic?

your setup is the same as mine, just a stage one instead of stage 4, like tweak posted several posts up.
its a 3s pressure plate and disk, with 5s spline.
