So I understand that the full monty / super monty is a great clutch, but what is like to live with on the street? My wife will be driving this car as well, dont want something that will be too heavy or something that shudders a lot and reduces the drivability of the car too much.

I know it is always a trade off between comfort and strength but I'm just trying to get some real world opinions.

Cheers :)

i can comment here...i had the full monty with a solid centre which should make it not as pleasant to drive & it honestly drives like a normal clutch...put it this way, my wife drove it with no problem at all & she was amazed (she can also drive my triple plate clutch but absolutely hates it), this is also the reason why im getting another jim berry clutch for my current gtr (so that my wife can drive the car)

there is no trade off here between comfort & strength, comfort is 10/10 & strength is 10/10 if it can hold 1050rwhp :)

Jim Berry clutches are the best single's you will ever buy and will out last and out perform most twin / triple setups that are over hyped. The key is clamping force and the type of friction material

How much is the super monty costing you? I got a carbotic clutch and honestly even now and its only 100km old, there isn't much shudder. Its more noticeable in reverse but it will wear in. It cost 380 and its rated to about 550nm torque. People don't understand, a clutch does not slip from power it slips from torque.

I just got off the phone with jim & ive ordered my second jim berry clutch as i sold my previous engine setup – there is nothing better out there & im running over 400awkw!

He has recently released the improved “Super Monty” which is the predecessor for his “Full Monty”.

Here are the amendments which makes it stronger & improves driving even further:

1. Runs an exedy pressure plate which has better materials & “the best in the market” in his words

2. Runs larger truck buttons rather than previously used car buttons

3. Surface diameter increase from 240mm to 250mm

4. 6 puck clutch plate rather than 5 puck, with sprung centre

Jim is going to get cracking on my clutch today & will be ready next week, clamp pressure will be over 4000lbs as per my brief & could be as high as over 4500lbs.

I’ll report back next week once its installed...

As a reminder, 1 of his claim to fames is Mattouk’s drag vl turbo with rb30 which makes 1050rwhp & runs the “Full Monty” clutch – he actually split his block which almost makes the jim berry clutch indestructible!

i stand corrected, typo...

The “Full Monty” is the predecessor for his NEW, LATEST & GREATEST “Suuuuuper Montyyyyyy”

I just had a call from jim - clutch is ready for shipping which is super quick service & have booked to have the clutch fitted next thurs :):):)

My wife can drive and is the only female that is allowed to touch it, I have many stories haha...she raced a built xy gt with my gtr yrs ago and absolutely slaughtered it, she came in 3rd place in a gokart race and this is amongst my 20+ mates who all are pretty much into cars etc

I understand your concern though as neither of my ex girlfriends would even sit in the drivers seat

Why doesn't anyone ever post the cost of the clutch?

How much is this super monty and how much is the full monty?

your best to ring Jim Berry as each car is different and each clutch is different ring him up tell him what your doing and he should help you with what clutch/pricing etc.

I just bought a jun forged flywheel for my R34 GTR $530 del from access autos and a NPC ceramic button to suit around 350kwatw (thinking ahead) cost me 950. Awesome clutch, nice to drive and the Jun lightened flywheel makes the car just rev up so much quicker. Also put in ARP flywheel bolts aswell (around $100).

the super monty is about $1700.

in terms of how it drives, ive had an os giken triple plate & an exedy twin plate in the past...put it this way, anybody who knows how to drive a manual can drive my car without any issues at all (almost identical to a factory clutch), with multi plates you need to gain a nack & skill to learn how to drive it which isn't actually bad at all as i used this as an excuse when a friend or wife asked to drive my car haha

Rolls,

When attaching anything to another object, "Sound Engineering Practice" requires that you have the following:

1) One method of locating (dowels/flange etc.)

2) One method for fastening (screw, nut/bolt etc)

If it were me, I would not install the clutch/flywheel ASM without using this dowel as the fasteners will then be loaded in a way they were not originally designed for. Hence they MAY not be sized appropriately to the task and MAY fail

Cheers,

David

Hey if you put the flywheel in minus the dowel, but line it up where the dowel is meant to be will there be any issue? Is it just for locating the flywheel?

Dowels are there for a reason, if it was a matter of just line it up with bolt holes, then that would be all there was to do.

They are for alignment and balance, but most importantly to prevent clucth assembly sheering bolts, turning/moving at all on fly wheel.

Bolts are doing a job, they are there for clamp pressure and not shear resistance.

Dowels on head and bell housing are for proper alignment, different job. :cheers:

Half the flywheels DON"T have the dowel though, this is why I thought it was no issue, rb30e and quite a few aftermarket ones are missing the dowel hole.

The single dowel pin is about 1/4 the diameter of the flywheel bolts, I really doubt the added shear capactiy would do anything, if it was going to shear without it they would use different bolts. I am just not sure what the reason other than locating it is there for.

Surely they would have two opposing larger dowels if shearing was the issue? I am fairly sure the bolts are hardened steel of some sort, probably similar to the dowel, wouldn't the shear properties of the bolts even if a weaker grade still be far in excess of the dowel?

It looked like the dowel only located the flywheel itself, it didn't stick through and touch the clutch? If it went through the clutch then I see your point.

      From Japan and back to Europe, my sh*tbox R34 GTT

      Yeah, I get that. I try to be as cost-efficient as possible with cars, and typically prefer to buy them at the bottom of their depreciation curve. I was looking at those Bilsteins too as they're roughly in the same price bracket as the BC's - lack of adjustability and being soft put me off, not that I want anything too hard. That's my issue with the Skyline, it's too expensive and it's reflected in my driving. I don't mind going full pelt as long as there's a gravel trap to catch me. Really, proper safety equipment is needed for total confidence. Well this just turned up for the BMW. I'll try and get the front together tomorrow and take some pics of the absolutely horrid rear end; perhaps I'll have a crack at the rear on Wednesday. I need to make the car drivable before the weekend as I'll be driving it over to London.

      While going through data logs late last week, I spotted a small issue with my WMI. My WMI starts to progressively inject at 11psi of boost. I'm using a 25psi cut in pressure switch on my WMI as an added safety and if the curve is linear, I should hit that 25psi on my WMI system around 13-14psi of boost.  As per my data logs, my WMI pressure switch only activates around 19psi of boost. This is causing my non WMI 4D map to trim for WMI. I'm presuming this is caused by the mechanical switch response time, injection curve not being linear or both.  I ordered a 2-10psi adjustable cut in pressure switch which should correct this. If this doesn't resolve it before my dyno appointment on Friday, I'll just remove the pressure switch temporarily and more than likely replace it with a pressure transmitter afterwards.    BTW Speedtek has yet to refund me.
