Quaife or Blackline

[clio_cup]

Apart from the £400 difference is there any benefit to having one over the other?

 

[Advikaz]

Basically the same thing.

I’ve got a blackline in mine and it’s fine.

@NorthloopCup can sort you out

 

[mumpy]

Same here, blackline

 

[Matt Cup]

Am I correct in thinking that the black line requires a gearbox oil flush when used for a few hundred miles as it’s not been as finely machined as the quaife?

 

[Krarl]

I've got a Quaife gearbox for sale if you're thinking of buying one

 

[the_baron_von_richthofen]

I've got a blackline and its brilliant, seems to be handling the extra power too.

Never heard of having to flush the gearbox oil though, where did you hear this @Matt Cup ?

I was speaking to a bloke who had one fitted and he said that due to the machining process being less refined (it’s a quaife copy I believe) he was advised to dispose of the gear oil after a short while due to possible contamination.

I’ve been looking at the blackline too for my spare box that I need rebuilding at some point.

 

[Advikaz]

/\ good practice with any diff I would imagine.

It does state to do so in the info it came with yes.

 

[the_baron_von_richthofen]

Mmm, I see on google it mentions to flush the oil after 500 miles.

Better put this on the ever growing list of things...

 

[Matt Cup]

Can you use regular Elf NFX oil with an LSD or do you need to use something more specific?

I used Fuchs Sintofluid as suggested by @NorthloopCup

Just go for redline MTL 75-90 GL4

It's levels ahead

This is what I have, hence a little gutted to flush it out but needs must.

If you can get it, it was NA when I was looking!

 

[the_baron_von_richthofen]

Actually, im using the MT90, not sure what difference that makes other than it seems to be more expensive.

I think they renamed it

So MTL is 75w-80 and MT-90 is 75w-90

 

[NorthloopCup]

MT90 has a higher operating temp range so I recommend it for gripper boxes and heavy track work.

MTL for road and light track work.

I’m pretty sure that blackline suggest you drop the oil after 500 miles. The first one I fitted for a mate got hammered immediately and it never had an oil drop.

I recommend the Sintofluid as an alternative to MTL when it’s not available.

 

[Mr Trailer Man]

Opie usually have a good stock of MTL and MT-90.

I usually go to Opie or I found Fuzz Townsend's Classic oils for it

 

[clio_cup]

Thank you all. Is there any other bits worth doing while the gearbox is out? Will need to get it sent to Northloopcup to have it fitted and the gearbox refreshed at the same time.

 

[the_baron_von_richthofen]

Clutch and light flywheel as its all exposed.

 

[NorthloopCup]

As above, but remember you’ll need new flywheel bolts if you do the flywheel, and more importantly, don’t buy a ‘oem’ valeo. They’re s**t quality and fail when under load.

It’s worthwhile looking at the sump gasket when the box is off too - quite common to see them leaking, and access to the bolts at the bell housing end is much easier with the box off.

 

[clio_cup]

What brand of clutch would be recommended?

 

[Krarl]

Genuine or Sachs

 

[Advikaz]

Sachs performance if it’s being tracked
