65. Fit the cover using the four M6 bolts provided, torque down to 7 ft lbs / 9nm – you can use a drop of medium strength Loctite here for added safety – I don’t because I hav the chin spoiler over it, and I haven’t had a loosening issue with these yet – don’t forget your Rotrex sticker on the pulley
66. Refit the water pipe from cylinder head to water pump, and the water pump as per manual section 12.8 – you might have to sand down the hole in the new front cover a bit so the pump will go in – take care not to shear the o-ring – you might also need a couple of stainless steel washers to fill a gap, also the bolt pointed out in the photo needs to be taken back out to fit the water pipe to cylinder head (clean threads and re-Loctite)
67. This is what the supercharger traction fluid or oil circuit looks like;
These are the lengths I used when fitting mine;
650mm from outlet of supercharger to inlet (top) of oil radiator
1300mm from outlet (bottom) of oil radiator to inlet (top) of canister/bottle/catch can
370mm from outlet (bottom) of canister/bottle to inlet of oil filter
1500mm from outlet of oil filter to inlet of supercharger
+++++
68. Fit the supercharger to oil radiator hose to the supercharger outlet, and the oil cooler top end fitting
Note – the Rotrex circuit diagram has the radiator in a horizontal position, however we must mount it in a vertical position on the left side of the engine coolant radiator – the logic used is that if the hot oil from the supercharger flows into the top of the radiator and downward through it, heat rises naturally so will leave the oil in the opposite direction to the downward flow of the oil
69. Fit the supercharger inlet hose to the supercharger inlet also – you might get a better fit by using some elbow connectors – run both the hoses from the supercharger across the front of the engine, tucked under the lower radiator mounts, to where the oil radiator will go
70. Fit the canister/bottle/catch can in the stock air filter box, using the band clamp to hold it to one of the old air filter cover bolt holes
71. Run a hose from the bottom fitting on the oil radiator to the top fitting on the canister, taking the route of up over the engine coolant expansion bottle, under the left chassis spine, down under where the fuel tank hinges and into the stock air filter box
