Diffs! Specifically Blackline.

[Nathan105e]

Looking to send my gearbox to NorthloopCup and having a diff fitted whilst there.

I was settled on a quaife, But then..

I've seen and heard bits from Blackline, mainly appear to be popular with 197/200 folk.
MattLewisRacing have one listed for the JC5 gearbox but nowhere else has any blackline ones listed for JC5.

I've seen they've sold a few,

Has anyone HERE bought one for the JC5 and its been correct and a straight fit (I don't want to cause problems for Mark fitting them if I can avoid it)

And also, how do they perform on track, and has anyone had any issues?

Finally, what's the warranty, if any?

For anyone else interested in the blackline diff, I now have a blackline diff in my possession to fit in a mates gearbox. It’s nigh on identical to the quaife, and I will be fitting it in the box tomorrow evening for a dry run - just to see what the fit is like.

If it’s all good, I’ll then fit the crownwheel and start building the box. Will report back in here to update as I go along, but I’m not envisaging any problems tbh.

After that, the next update will be on the 2nd of August as it’ll be on track being put through its paces!

I have a Blackline in my 197 racer and it's pretty good. It does lose traction occasionally unlike the Gripper in my 182 but is perfectly acceptable. The KTec Clio 197 race cars have to run them too.

Did a trial run with the diff fitting this evening. Fitting was fine and no preload adjustment required!

Heated the crownwheel and fired it on the diff.

Only negative is the thread for the nut isn’t as nicely cut as you’d get on a quaife, but, the nut tightens down to torque spec, so all good!

Good to know mate! They work well in the mk3 clios too.

Do they just press off the old and onto the new? And also do diffs from Clio 200 fit 250 meg as I’m looking at getting Meg but Dunno if it’s cup or not

Mk2 crownwheel needs to be machined to suit the blackline - the same as the quaife. The mk3 crownwheel is bolted on. Couldn’t say if the diff fits in a Meg box though I’m afraid.

Update on this! My mate has been driving the clio like a hooligan with the blackline diff installed, and it’s all positive noises coming out of his mouth.

On track tomorrow. 👍🏻👍🏻

 

[NorthloopCup]

Well folks, the diff works and from what I’ve seen, it’s on a par with the quaife. Only difference is that it’s cheaper!

broke the clutch at 3pm, had great time upto then, had to nurse it home. I think it heard me talking to you and decided to give me an excuse to get one ;P

 

[J.Nev]

Perfect timing for the clutch to give up 😂
