So, im throwing on some more power adders to my lancer, now my question is, does anybody know whats the maximum amount of torque the stock clutch can handle without slipping?

iv heard it can handle 30% more than the stock torque, but this may not be accurate.


So if any of you guys know please tell me!

 

Sorry man but these (RRM Crank Pulley, Fujita F5 Short Ram, RRM Ceramic Headers, Magnaflow Exhuast, Tenzo DC6's) are not exactly "power adders". Now the turbo just came out and the stock clutch is supposed to handle it, and i would be concerned about the clutch in this case but NA mods don't add enough HP to stress the clutch. Take your car to the dyno and you'll see you've got nothing to worry about!

 

the only mods currently available that would warrant a heavy duty clutch are the turbo (and the stock clutch has been confirmed to work with it), or a NO2 kit and that only depends on how big of a NO2 kit you go with.

 

sorryi should have been more precise.

that list of mods in my signature are the ones i already have, i should have said "bolt ons". Im not staying NA for long, iv been doing my research into good old nitrous. I know i would have nothing to worry about with my clutch and the engine being NA.

My buddy threw a 75 shot on his G5 with the stock clutch and he fried it after 4 runs. Even then he engaged the nitrous at 3,500 rpm in second, so it wasnt like he launched with the nitrous activated.


I just dont want a repeat happening to me. Im only considering doing a wet 50 shot at most, and nothing higher until i beef up the clutch and valves, etc.

But i know its cause his clutch couldnt handle the excessive torque so it just ended up slipping a bunch and fried.

 

There is someone in the forum who has done 50 dry shot and he hasn't complained about the clutch. You can ask him if there are any issues just do a search. but you see the clutch is one of those things that may not wear out immediately and you don't know until the clutch is gone at let's say 15k miles.
For mods like turbo or nitrous I would say that it would definitely wear out faster than on a stock car but how much faster I don't know. It is logical that did not put a heavy duty clutch to handle such things but instead used a cheap clutch which is decent of 150 and a little more HP applications.

 

is this gentlemen you speak of have this 50 shot in an 08?

im an apprentice mechanic so i know very well how cheap some of these parts are, and obviously the stock drivetrain isnt designed to withstand high hp gains, sometimes even moderate gains, like a small sized nitrous shot. I wouldnt even consider using a dry system, i dont trust em, i feel like you gotta have that extra fuel to keep the engine running correctly, dont wanna go on the lean side.

I guess i was just looking for an exact or close amount of specs on the clutch for this car. Im not worried about the flywheel, just the disc and the preasure plate, cause those are gonna go before the flywheel for sure.

So long as the nitrous is used in very considerate moderation, and the proper shot, theres no reason for accelerated wear and tear. But you have to be very percise and have everything set up accordingly to get those kind of results.

 

This is the thread:

he never mentions anything about the clutch, and the people only care about what the engine can take and not the clutch. Seems like you know what you're doing but you gotta understand that the lancer is a new car and we still don't know much about how much the drivetrain or the engine can take.
I'm gonna try and find some info about the clutch on the service manual.
Will post if i find anything useful.

 

Clutch disc type
Dry single plate type
Clutch disc facing diameter OD x ID mm
225 × 155
Clutch cover type
Diaphragm spring type
Clutch cover setting load N (lb)
4,320 ± 350 (971 ± 78)
Control system
Hydraulic type
Master cylinder ID mm
15.87
Clutch fluid
Brake fluid DOT 3 or DOT 4 (commonly used as brake fluid)


These are the specs of the clutch according to the Service Manual, I don't think it helps.
It is safer to wait until somebody tries these mods. Hopefully some performance clutches are going to come out soon for the 08 lancer.

 

ya man, iv been doing plenty of research into this. I know its a pretty new car and a whole lot hasnt been found out yet in the aftermarket department, some people will be guinne pigs and tell us what happens when they did something that hasnt been done yet, and we learn from their mistakes.

Nitrous is a very touchy subject, so we shall see how things go. Im gonna be installing the kit in about a month or so, so when that all goes down il be sure to leave feedback on how the lancer responds to the bottle.

And ya, if you find anything usefull please do post! thanks man.

 

When the ralliart comes out, if it has the exact same clutch then that would be a guarantee that this clutch will hold good but that is highly unlikely.
Edit: I forgot that the RA will first be offered only with the twin clutch automated tranny, sorry

 

heres what the manual has to say on the clutch

Clutch operating method: hydraulic type
Clutch disc type: single dry disc type
Clutch dis size OD x ID mm (in): 255 x 155 (10.03 x 6.10)
Clutch cover type: Diaphragm spring type
Clutch cover setting load N (lb): 4230 +- 350 (971 +- 78)



not sure what that cover setting load is....hope this helps

 

i think what il do for percautionary reasons, is start off with a simple 35 shot. If the clutch holds up with no slipping, then after a few runs il throw the 50 shot nozzles on and see how it goes.

Then when hopefully clutchmasters, or Exedy, or any clutch company comes out with some more heavy duty preasure plates and discs, then il bump it up to a 75 shot and keep it there till i beef up the internals, then possibly a 100 shot in the future. but thats a long ways away.

 

a 50 shot should be ok... the turbo kit only gives ~50 extra HP and the stock clutch is fine with it...

Then again... there's a slight difference in how that power is delivered. As noted earlier, someone on these boards has a 50 shot in their car and hasn't complained about frying his clutch yet... so, you might be good.

In the end, the only way to know for sure is to do it and find out :P

 

Don't bother for now. If you mod it and start to get clutch slipping, THEN worry about replacing it. You might be pulling out a perfectly good disc for nothing.

 

Trust me, i have no intentions of pulling my disc out unless im certain that its not gonna hold up. All i can do is bolt, tune, and hope for the best hahaha. And if i notice the disc starts to slip when im spraying, im gonna shut it down right away, cause if i keep doing it im just gonna make it worse. Then i would know to drop the shot level down.

I mean ya the turbo kit throws out 50 hp, what about the torque though, thats what im more concerned about, dispite it being a 50 shot, my torque will be higher if i get a good enough spray at the right psi.
And like you said, the power is delivered differently, turbo, lag, nitrous, instant. I hope that guy in that other forum isnt lying when he says hes running nitrous lol. Cause if its true, its a big confidence booster.

so does anyone know how much torque the RRM turbo kit puts out?
