How much power can a lV a KEP 200 mm IV pressure plate handle?
 

Hi

As the subject says, how much power can a KEP 200 mm IV pressure plate handle with an organic disc?

This is with a roughly 950 - 1000 Kg car, G50 trans, 2 litre WRX STI motor, with about 190 kW at the wheels.

Steve

190Kw?
I know the KEP clutch in my DeLorean handles 1.18 Jigawatts of power no problem. Thats with juice master 2000 mod on the flux capacitor.

You got this sitting next to that ghia with 9's all around without tubs right?:rolleyes:

Actualy it is..... WEIRD! huh

Thread whoring

I don't see a DeLorean. (just a bug that was ruined IMO) Your 9's WILL rub from looks of pix with full weight of car in a corner at speed. The only reason I even replied to this thread is because Steve C was asking a good question, and I did not like seeing your reply. (as well as others posted else where) This site is for people who share a common interest in learning and helping each other with VW's, not bashing, like another site I know. (and not a member of for that reason) This site has a good reputaion for being understanding and helpful to members, and think we would like to keep it that way. Don't get me wrong, I can be a very good smart A$$ myself. (just ask any of the VKG) But there's a time and place for it...

Sorry Steve, for thread jacking, but if no one else is going to say anything.

Have you looked on the KEP site for HP ratings on the pressure plate?

You should look at what country people are from and what acronyms they use before you push the "I'm a jacka$$" button.

Ok jeez. Didn't know membership to GL included removal of you sense of humor.

Leaving your sense of humor isn't manditory, but you do have to know how and when to use it. Miami Valley Smack Talk doesn't always translate well when it crosses the mighty ocean. Most of us here know what 190 Kw means. Remember, this is an international crowd and we don't want to look like "Stupid American Jacka$$es". That is what thesamba.com is for.

Hey now. :shocked:

I took it as a joke and not insulting.

Send a link to the movie next time to make sure everyone is on the same page!

Jigawatts... you're silly!

Back to the future...yes most know this, but my point was Steve C normally ask questions expecting a serious answer (from seeing his postings), and being from "down under" might not have seen that movie. (good point DORIGTT) Plus, trogdor throwing smart a$$ comment's in several posts of legitiment questions to the pursuit of VW performance is not the norm for this site. (particularly since he's new to the site)

So your saying people from Australia don't have movies? ..... from the 80's? ..... either way it was funny and I'm sure SteveC saw the humor as well.

And since you guys have been too busy to answer the original quesiton and continue to take it farther off topic because of a silly reply , yes it will handle the power.

I would think a 200mm stage 2 KEP would handle an STI engine. A stage 1 is not what I would use with a stock disc.

Hi

Thanks for the serious replies. I like Mr Eds philosophy, don't talk unless you have something to say

I already have the stage IV Kennedy 200 mm and it is rated at 300 ft. lb. and the one that Kennedy sell for the G50 is rated at 600 ft. Lb.

I'm just getting cold feet, I like to try and do things once, so I'm worried that the stage IV Kennedy 200 mm might let me down.

Steve

My stg3 kennedy with "gold" disc handles the 245whp that my ra engine puts out just fine.
Took it off after about 1000km and there is no sign of slipping or overheating

Hi

Kennedy state that the IV can handle 300 ft lb / 406 Newton Meters of torque with an organic disc. The factory STI torque figure is 253 ft lb / 343 Newton Meters, so I might be getting close to the clutches limit if I bump the boost up a bit.

I bought my adaptor when I was going to use a Type 1 box, that's why I have a 200 mm flywheel. I'm just wondering if I should bite the bullet and get a proper G50 clutch?

Kennedy have a G50 pressure plate that can handle 550 ft lb / 745.699 Newton Meters.

Steve:
I've just ordered a G50 adapter kit from DS Tuning, they quoted me €450. Stock Porsche clutch I think is the way to go, gives you the option to upgrade later on...

Hi Rich

I've been corresponding KEP, they have been very helpful. I think I will take your advice and go with a G50 clutch.

My G50 has the old style release lever so I need to do an upgrade as well.

Parts from Pelican
Improved (G-50) Clutch Release Fork, $165.75
G50 Improved Operating Shaft & Bushing Kit - Does NOT require drilling. $186.25
Clutch Slave Cylinder $87.50
Updated Throw Out Bearing Guide Tube $68.25
Throw Out Bearing $228.50
= $923.50 plus shipping

Parts from KEP
G50 light weight pressure plate $650
Organic Race disc $269 + 85 shipping
= $1004
Adapter kit is $580 + 100 shipping.

At least I can sell my existing adapter kit.

Steve

I have a feeling you will never have to upgrade that set-up!
I got a full clutch in good condition with my gearbox so will use that, at least to start with. I've heard of the upgraded release shaft, looks quite pricey to upgrade, they aren't that problematic are they? I was considering getting my 200mm flywheel and a Porsche flywheel welded together but I'm happy with my decision to get a new kit, I can sell the old one as a complete adapter kit now and a one piece flywheel will be much better...
Sounds like KEP's prices have come down, I got a quote just for a G50 flywheel quite a long time ago and it was considerably more than they quoted you.

Hi Rich

After reading a few posts on the Pelican forums they seem to have trouble with release bearing shaft corroding and sometimes the needle bearings falling apart. Mine was in beautiful condition.

There was also a horror story of the whole release bearing support ear snapping off. There are 2 ways of upgrading the release bearing support shaft, one bolts in the other needs drilling, I've heard that the drilling method can weaken the release bearing support ear.

I only got a pressure plate & ring gear with my G50, so I could get a clutch plate for about $300 and try my luck or Pelican have a well priced kit.

This kit includes:
Sachs OEM Spring-centred Clutch Disc
Sachs OEM Pressure Plate
Pressure Plate Bolts & Washers
Sachs OEM Throw-Out Bearing
Throw-Out Release Fork (Improved)
Flywheel Seal
Flywheel Bolts
Flywheel Pilot Bearing
Slave Cylinder
Slave Cylinder Hose
Clutch Alignment Tool
$1189.60

+ G50 Improved Operating Shaft & Bushing Kit $186.25
+ Updated Throw Out Bearing Guide Tube $68.25
+ Shipping

I'm going to have to try my luck to begin with, budget is a bit strained at the moment and it will only be a toy... I will make sure it is all well lubricated though..
Rich

Hi Rich

I forgot to mention, the stock G50 clutch is rated at 460 ft lb, where as the 200 mm Kennedy IV is rated at only 300 ft lb, so you should be OK.

Im still working on my shell to get it to the painters, but I need to have my head around all the little intricate things that pop up.

Steve

the best bit is that wiht the bigger diameter Porsche clutch the pedal will be much lighter..

Glad to hear you are busy beavering away on your car, I'm preparing to lift the body off and see how far the rot has spread...
