The motor sits behind the drivers seat getting very little cooling air , does pretty well on Methanol , poorly on gas . The angle from the countershaft down to the rear axle is steep and can cause complications . This one was originally built for a Mr Abacassis I seem to recall , Irving working on it personally . It ran off the track and received damages at some point . Later to be sold to David Cooper . Cooper brought us the steering linkage which was in beat up shape and our machinest Ron Baralli corrected the damages and beefed it up . Cooper did a full restoration on the chassis and alloy body and she was a polished beauty . Into this then went the rebuilt powerunit , really an honor for our shop .
Rather than polish it I finished it up in a manner I thought would improve the cooling . Using a medium flap wheel I went over the cases and covers carefully to increase the surface area and remove all polished metal . Irving has written that a dull surface radiates 9 times the heat energy of a polished one so I followed his lead . It was stunning , all business , and David never spoke of it overheating . Sid .
