I've now done 1200 miles on newly built engine and apart from low fuel pressure figures, it is running well - mechanically it feels good, quiet idle, oil pressure is a solid 2 bar when hot, compression 9.2bar on all 5 (no difference between cylinders) not great but higher than the outgoing 7.5bar and it pulls well from 4000 revving cleanly to 7000rpm as it should.
Seemed like a good time to add an oil cooler - it should have had one from the factory as although there is no turbo to heat things up, pre rebuild i regularly saw temperatures nudging the 130 graduation on the gauge.
I used a Mocal 16 row 115mm matrix cooler which was a few square centimeters more in cooling surface area than the ABY cooler but was more of a square than a rectangle. Setrab website recommends taller and narrower to minimise pressure losses, if you can fit it...
Factory location won't allow tall and thin so i set about making a new bracket and duct, here are some pics. Works really well - oil temp gets to first graduation on the scale (90deg?) when really pressing on, falls again quickly when cruising. happy days.
3B thermostatic filter housing bolted on to supply the cooler.
Alu mesh over front of duct to keep leaves/stones out.
Duct made round a foam core mould. Laid up wet glass fibre and added outer layer of carbon for no other reason than it looks nice!
Aeroquip push fit hoses. good for 150deg C and 17 bar. nice short and direct route.
not the prettiest of brackets but it took an afternoon of cutting and welding metal i already had, it is sturdy, doesn't vibrate and will last. (2mm wall tubing!)
