Torque is what you feel :). Some people on here will say that a clutch can't handle the power, but it definitely can (providing it isn't already knackered).

See below image of a dyno printout achieving about the most torque you can get without smoke. To get more power a larger turbo needs to be fitted.

Interesting graph, what units are those then? Smarties or liquorice all sorts.?

Lbft and HP. No need for comments like that. It’s an actual printout unlike the “160” ones.

On a serious note, I'd like you to calculate the maximum permissible torque transmission of a CDT clutch.

The figures are

A driven plate with external diameter of 228mm with a friction coefficient of 0.25

An axial clamping load of 1484 lb exerted by the pressure plate


No flim flam such as your clutch will be fine if it's ok, but if it's knackered it won't etc will be entertained, and your working out figures must be shown.

i have a question for big russ
reading the threads on this forum on remap the ecu the facelift diesel has to have the ecu remaped so is it done on the T4 with the X power software and can the bhp be increased from 131 to 160
david

The genuine XPower upgrade only unlocks a certain thing in the ECU.
All 116 are capable of 135.
All the upgrade does is remove a "gateway" to the full map.
The disc on it's own is pointless. That just allows T4 access to an area usually locked. Every disc is the same.
Now comes the clever bit :D
If you ordered this from XPart, you would receive a disc, instructions, a certificate which in theory you send to your insurance company and a sort of metallic sticker that should be attached just above your VIN plate on the A pillar. What you also get, is the Unlock code for your VIN !
These are unique and are generated by some Pixie at XPart :D
The 160 upgrade was never official but I understand it works well. Just don't ask XPart for the 160 version :getmecoat:

If you really know what you're doing on T4 you can access the unlock code for the 135 upgrade, you don't need X-part to generate it. But the car has to be present. ;)

But if you do go through X-part you get a nice sticker for your B pillar :getmecoat:

Apologies. I meant B pillar. But this was the official MGR way of doing it. Nowadays there is various ways of upgrading stuff. But people want OE !!:getmecoat:
Personally, I would not bother with a 2000cc diesel if you want some HP and grunt.
Not in a car the size of a R75.
Never going to happen.

Even my ZTT 190 would not blow you away, performance wise.
Compared to a Skyline for example.

Thats a thought...
take the engine out of a Skyline and match it to a Kawasaki Z1000 engine system.A
Wow. It has been done by the way.
Was put into a ford ute pickup . 0 to 100 in about 6 seconds.
And yes, it was street legal ! :bowdown::bowdown:

Thanks for sorting it today, my son Steve says the car is a beast, and I have to agree. More go than our last 2 litre v6, doesn't sing the same noise as a V6 on full throttle but really does go. Should have done this out of the factory when new!

Wouldn't you need the the surface area of the friction plate and not just its diameter ??
