You need to drill a hole in the cylinder head for the timing belt tensioner so it’s the same as a 1*2. Lots of work. You need to use to the mk3 inlets as well. 1*2 will not work.

That my friend is the clio mk3 cup racer roof scoop. Mine was a genuine one, but I’m pretty sure cm composites copied them - so I imagine they’ve been copied by the other companies now. Great bit of kit and they work amazingly well.

Go big or go home. 😁

I made 230bhp using Megane 225 injectors and a standard fuel pump. The fuel system was totally stock except for the injectors. 100% the standard injectors are NOT up to the task @Oddesy

What an absolute pucking fenis he was! Clearly has knowledge of dildos and pegging going by one of his posts. I heard on the grapevine his girlfriend called him a paedo. He replied telling her, that’s a big word for a 12 year old.

Lockadildo has struck I’m afraid.

It’ll be the same as shimming the standard oprv mate, so yes it has been done and I’ve done it myself. Small penny washers are all that’s required to do the job of shimming.

That’s where the maths comes in! Lol

Camber shims are ok, but the beauty of shim steel allows for finer adjustment mate.

Shim the rear stub axles so you’ve either got parallel or slight toe in. It’ll help the turn in massively. Some stuff called shim steel is your friend for this.

Well 80hrs ain’t that much on a road engine, but on a race engine it’s quite a lot mate. There’s not much scope for increasing the oil pressure on the formula setup either as the oil pump is pretty s**t tbh.

Lol that’s not ideal then

Get a piece of 25mm silver steel (from memory the cam journals are that size) and put it in place of the exhaust cam. If it turns freely, the cam journals are worn and the head is essentially scrap. You can get the cam journals line bored, but I’ve only found one place in the UK that could do it...

Right ok. There’s only one place to put the restrictor in the block mate as there’s only one oil feed into the cylinder head.

Do you have vvt? Or is it not used on the formula engines? The exhaust cam journals wear out and you lose oil pressure there. You can run an oil restrictor in the block to help improve oil pressure as well.

Tell him he needs to man up and register on here then lol

How much more convincing does he need?! If he’s on here, tag him in here lol

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!

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. 👍🏻👍🏻

Change the oil to redline mtl and re bleed the clutch.

I’ve got a 129 (same as a 130, just has a speedo drive) that I can build up? It will be fully rebuilt and reliable. Pm me if you’re interested @HarleyV123 👍🏻

You’ll probably find that the diff is worn internally - namely the planet gears have worn into the casing. It’s boot unusual to see tbh, but it means you’d need a new diff regardless. I know the exact noise you’re describing and I can confirm the noise when up in the air is normal. As is the...

No worries 👍🏻 Well you need one with a speedo drive.

I’ve got a 089/129 gearbox that I can rebuild and supply if you’re still looking for one?

Yep. Got one I can rebuild @Stevendjk

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.

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

Lol

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!

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...
