at last the water injection is all sorted with richards help from drl i had to remove the board from the casing break the tinniest of links and solder a new link to give me the required volume of water injection, trouble was they assumed we had 100% drive to the injectors when on full throttle but that is not the case we use around 68%at full throttle so had to move to x1.5 on the scale hence the soldering but all good now, i also fitted the passengers seat tidied up the wiring to the aquamist ecu and put it in conduit and refitted the dash so just the line locks to go.

well after much testing we have come to the conclusion that the super light flywheel is the wrong choice for us, the engine is incredibly responsive and as a pure race car would be fine but as a track plus road car its to aggressive, so a 12kilo flywheel has been sourced with a high proportion of the weight on the periphery to damp the engine better, we are keeping the superclutch very pleased with that and as the gkn lsd was very tired a new btr is going in, i have stripped everything out again diff has arrived and will be going in tomorrow, new flywheel should be hear next week so just got to build it all up again.

I have at last got the new btr diff into the car unfortunatly the two front brackets supplied allegedly to allow the fitment of the btr where a gkn had formally been did not quite line up so i have had to remove 8mm from the nearside bracket and extend the off side by the same amount the rear bracket is perfect but all well now they are all repainted so will be funally fitted next week.

back into the transmission rebuild for the second time i have now modified the brackets for the btr diff so it fits nicely into the chassis all done up drive shafts fitted etc. i have used the cerb ones as they have done little mileage and i am now in possession of a nice new 12 kilo flywheel for the superclutch so first thing monday will get straight into fitting it all back together.

The brackets just didnt fit right they pulled the diff over to the drivers side far to much cant quite see what the difference with our chassis is if the ones supplied do actually fit other chassis.

Still using the lt77 reason for the change to a shaft with a damper is the triple plate clutch has no spring damping the driven plates are soild so a bit of damping should help the new diff survive plus make the drivetrain a little more civilised on the road.
