Ok all, sorry for slow updates. I have been really busy working - lots of travel and limited 818 time.
Over the past fortnight between work travel, I managed to fit some new lower arm rear bushes. I used some caster adjustment units from PowerFlex, these offset bushes push the rear of the aluminium lower arm outward (when installed correctly). This increases the clearance for the front wheels. In addition I added new tie rod ends, steering rack boots - tightened all the suspension components and took the go-cart in for a full wheel alignment.
end of alignment:- Front:- caster 4.0 degrees each side, camber -0.6 degrees both sides, toe 0.6mm both sides, Rear:- camber -0.3 degrees, toe 2.2mm both sides.
caster bush.jpgFor the alignment tire pressure was set at 32PSI, and ride height was set at 4 3/4 inch in front and 4 5/8 inch in rear. The small increase in height over the standard 4 1/2 inch is to allow for body, windscreen and extra's yet to be added (more to yet be added in front compared with rear).
I also unlocked lambda sensing within the Motec M800 ECU, fitted a Bosch wide band O2 sensor to the rear of the muffler. The car still has a very rough base tune in the ECU (factory standard settings) no cam control, no IGN advance or fuel enrichment - So its books into a Dyno tune shop next week whilst Im working in Italy.
Upon completion, I'll tidy the wiring up, add some underlay and carpet, install seats and interior properly and start on complete body fitment.
During the tune next week, I'm adding a air temp sensor close to the throttle body (after intercooler). We will add a parameter to the Motec ECU which can/will adjust the fuel and boost as the temperature increases with hot conditions.

Finally I played by trial fitting some body (temporarily).
