oil catch tank 120-130

It’s going well. We did COT 2018 to try it out and then Peking Paris 2019 as a serious outing. No engine problems other than I didn’t take enough jets for the Weber’s to cope at 2500metres.

The innards came from Ben Flierman at Tinus Tuning in Holland. Billet crank, forged pistons and rods. His TT4 cam. Not good for big power (abt 115hp at the wheels with rally tyres, IIRC) but a flat strong torque curve. It pulls very well, which is what I wanted.

Big bore 4:2:1 header from KG Trimning feeding a 2.5” system.

Built with low compression (9:1) to cope with expected low octane fuels in Mongolia. I also ran a 123 dizzy so I could switch to a retarded curve on the fly if I heard pinging. We came 6th out of about 105, so the engine was a major part of that. A lot of the success was the car was strong and I didn’t loose time repairing it. A couple of repairs but spanner checks each night was pretty much all that it needed - apart from rear shocks.

Gary Comerford (Volpro) did build the engine. He did well, I think.

Will email separately.
