Jim Berrys Full Monty And Ogura 4.8kg Clutch....good Combo?

[nsta]

Hey guys, just wondering if this would work well for my street 25-t aiming for 250-300rwkw???.....anyone else using the same sort of setup??? i spoke to jim, and he said the full monty would be something i should look into. But he also says the full monty is a clutch which you dont need to customise, so in theory everyone has the same clutch specs if they buy a full monty from jim correct???

This isn't going to be a direct answer but, if you are honest about what you intend to do with the car when you talk to him you can trust whatever he recommends.

cheers, but he recomends just machuine the stock flywheel, whereas alot of ppl on this forum think thats dangerous, and ive seen good results with ppl using a lightened one.

thanks

The flywheel you suggest is far too light to be used with this clutch. Machine the standard flywheel. It creates no problems whatsoever. Stories of machining related flywheel failure are just that...stories, fallacy, BS, rubbish, rumour, garbage, and whatever else you want to call it.

who does machining???.......if thats the case, i save myself $500 to save for my gearbox:)

you normally lightly machine the flywheel when installing a new clutch anyway.

the full monty is pretty hardcore - jim advised me against it for my application

[nsta]

So no light flywheel then i guess.

you can normally buy a clutch kit from ogura or whoever - and they will normally supply a lighter flywheel that goes with the clutch.

i would strongly recomend a steel flywheel.

hrmmm. ask benm then buddy.

who needs legs or a firewall anyway.

There is a difference between lightening a standard flywheel by machining it and machining the flywheel to get the surface perfectly flat. The first is no good imo, the second is standard practice.

hmmmm. Pull your head in buddy.

I will put any money you care to name on the notion that benm's flywheel had a fault to begin with.

I'm speaking from my experience with my car not from what I suppose is fact based on someone else's car.

if you want a steel (aka billet) flywheel, jim has a guy down the coast who does custom job's. he's currently making one up for me to suit an 8" twin plate. cost is around $600

[Gts-t]

I run the ORC flywheel and have NO issues with it, SK told me if your not using the lightest one available ur wasting power/energy/whatever.

true if its for a circuit car only

put that car on the strip and have fun getting it off the line and keeping it on boost.

i don't really agree 100% with that. I agree that lightening a standard flywheel is a bad idea. and I'd agree that when replacing a stock clutch plate and pressure plate with a new stock clutch plate and pressure plate that it's standard practice so machine the flywheel and there is no problem with it. BUT when replacing a standard clutch with an upgraded (more agressive) friction material, and replacing the standard pressure plate with one that has a much higher clamping force I would personally NOT reccomend re-using the stock flywheel. it's a bad idea in my book.

[2rismo]

Failures in the factory flywheel where heavier than standard clamping loads were used are both:

A/ Few and far between

and

B/ Debatable as to whether it was even the clutch that caused the failure.

I have used one of Jim's clutches in my car for a very long (and very harsh) period and had no issues whatsoever. In fact, the clutch (without even being rebuilt) was fitted to another car once it was removed from mine and is still going strong to this day.

When i did my clutch just over 1.5yrs ago.All i did was rub back the flywheel surface lightly with emery paper.But next change will definently get a machineing.

A better clutch will engauge quicker,catching the revs quicker,than a stock one.Also a stock one will slip a a certain power level where as the more upgraded the clutch gets the more power it can handle.A standard flywheel will make the car rev slower to begin with but will hold the speed better at the top end.A lighter flywheel will rev quicker but wont maintain top speed as well.

This is where power comes into play (powerplay LOL).If the car has power it will rev to redline quicker and hopfully negate the feeling that the car isnt holding the top end as well.It is really noticeable in a car that hasnt got much power but has the lightened flywheel.Because the power isnt there to hold it at peak power.

Have you ever driven gran turismo 4?

Buy a bone stock R32gtst .Go and buy all of the flywheels and then buy twin plate and single sports clutches and hit the super long test track.Then sit there and rev the car and take note if it revs up quicker with the different flywheels.Then do a high speed run with all of the clutches noteing how fast u reach certain speeds and how easily it holds the top speed.Do the same but now do it with the different clutches.Now do it up with zort,filter,front mount & ecu and stage 1 turbo.Do the same and see what the results are.

Do timed 0-400m tests.Also 0-1000m tests

(do this from stock thru to racing flywheel)

dude gt4 is a computer game and it's not very realistic

just buy a decent known brand off the shelf ORC, EXEDY, OSGIKEN or ATS and i will gaurantee a better clutch for 99.9% of the applications.
