Euro S50 and Brake Boosters

[Massive Lee]

Hi Mike

Can't wait to see that great product. When it is ready, please let me know and I will post a picture and a link on Massive's website.

ok, your twisting my arm really hard. i might just have to pick this up (along with the massive kit) as my booster / master combo is not effective enough at the track.

nice work mike.

cheers, jason

I have received the prototype dual master bracket from my fabricator.

Very nice work! I should have it test fitted by the weekend.

I'm running the hydraulic setup on my S50 Euro, works just fine. Can be seen in this pic...

The bracket isn't going to cut it for Euro swaps. The side by side master cylinder configuration is too wide for the Euro intake (however it will work great for E30's with US engines).

Version 2.0 will incorporate a Tilton bracket that mounts the master cylinders vertically, like this:



I should have something created in the next week or so.

If anyone is interested in the Non-Euro bracket, drop me a PM.

The thing I'm worried about with the Hydraulic setup is on track ? how does it perform...

I couldnt care less for street, as the car is never going to be driven there.

Also being RHD it's a bit of a problem with the dual MC going into the engine bay... on a dual MC setup.

Any idea's on this ?

The thing I'm worried about with the Hydraulic setup is on track ? how does it perform...

I've been running the hydraulic setup for over 5 years without problems. It's done loads of track days, and multiple laps of the Nurburgring, and it has never once left me wondering if I can slow down.

I know some people have had trouble getting the system to work right, but I believe a lot of this is down to having the correct restrictors in the hydraulic lines. If you strip down the factory lines, you will find a lot of them have flow restrictors (small holes) built into the fittings. The O/D of the fittings may be 8 or 10mm in diameter, but the restrictor reduces this down to only a couple of millimeters. When I did my install, I made sure that I replicated all of these restrictors in the new hoses/pipework.

It's not an easy system to install neatly, but with a bit of care, and thought regarding placement of components, you can hide most of it apart from the large fluid reservoir.

Pics for Mike. Sorry these aren't the best...my camera doesn't like dark subjects. Plus it isn't the easiest thing to get a good pic of. Hope you can understand what I did.

Thanks for the reply... now I'm wondering how will it work, as I'm going to be using 325mmx28mm E46 M3 disc (or I might go for 330x32) on AP Racing 4 piston callipers, and 328x20 E46 M3 rear discs on std E46 rear callipers... how would it perform with this setup ?

Although Im starting to think the only way for me to go is the dual MC setup... should solve a whole host of headaches.

I'm running the 25mm (750i) master cylinder, huge Brembo 4 pots and 322x32mm discs on the front, and 280mm Z1 discs on the rear, so large brakes are not an issue with the hydraulic setup. At the end of the day, it's only providing assistance, and it doesn't really care what brake setup it's assisting. This is more down to the correct sizing of the master cylinder than the assistance method.

Update: Dual master cylinder setup that fits with the euro intake. No notching of the intake or relocating the mounting point. This has been installed on a couple cars and there are no clearance issues. It is a very compact (see dimensions), efficient design.

Looks clean!

Yep, they made the master cylinder.
