Mac#1 Motorsport Worx Build
Discussion
Spent a few hours yesterday progressing the hydraulic clutch conversion.
The upper bolt hole on the master cylinder was right in line with a small tubular cross brace on the bulkhead so I didn't want to use it and destroy the brace.
I made an aluminium adaptor plate to allow the master cylinder to bolt to the bulkhead, the upper bolt hole is countersunk on the rear of the plate to allow the plate to bolt flush to the bulkhead.
Fitted to the bulkhead it looks like this
Due to the position of the lower engine mount on the chassis the master cylinder has to be mounted slightly offset to the clutch pedal assembly, inside the foot well looks like this.
Playing with the position of the dry sump oil tank and Mocal laminova oil cooler, but really need to wait until the engine is back in to finalise this bit really.

I'm back again with an update which looking at the previous post is long overdue.
The hydraulic clutch slave cylinder fouled on the propshaft adaptor, so I had to redrill and tap new mounting holes in the transmission bearing housing in the locations marked with X's
Holes drilled, tapped and cylinder mounted to bearing housing.
Clutch hose made up with PTFE lined braided hose and reusable JIC fittings.
Installed to the engine it looks like this.
Clutch assembled with new EBC heavy duty spring, steel plates and kevlar plate kit along with the 6 arm lockup clutch assembly from Warpspeed Racing.

The clutch was filled with fluid and bled, but unfortunately while testing the clutch one of the slave cylinder o-rings was extruded.

A quick measure up and a search online led me to a place in Darlington called FPE Seals www.fpeseals.com where I bought some u-seals to replace the original o-rings with.
Here's a video of the fully operational clutch being applied and released.

Mocal laminova oil to water heat exchanger in position with the front home made bracket.
Rear bracket parts
Brackets welded up and painted black.
Oil cooler mounted to allow measuring up for coolant hoses and position of electric water pump.
Inlet manifold and boost pipework in position, engine bay is tight but workable.

Looks very, VERY similar to my new (to me) Mac1 MK Indy.https://youtu.be/YYXoUXPayyo
