Bowie69 Posted May 22, 2023 Share Posted May 22, 2023 What RPM, oil viscosity, temp and have you got the later pump? Quote Link to comment Share on other sites More sharing options...
Phill S Posted May 22, 2023 Author Share Posted May 22, 2023 Wanting to address only one thing at a time, I rigged up a cooling system using a Craig Davies water pump used on a previous project like so - no thermostat: I switched on the donor Disco 1 cooling fans at 80C and it was holding water temperature at around 90C as in the pic. The instrument pic was taken about 10 mins in, after which I shut down. I'd been running at around 2,500 RPM and mostly concerned about water temperature - wasn't paying attention to oil pressure other than that it was there. I'm using a breaking in oil from Real Steel - don't recall the viscosity but will check tomorrow. I don't have oil temperature instrumented (yet). But I believe the oil pressure should be more like 40psi? Quote Link to comment Share on other sites More sharing options...
Phill S Posted May 23, 2023 Author Share Posted May 23, 2023 (edited) Ah - but you meant oil pump! It's the later serpentine engine with pump driven directly from the crankshaft Looked up the oil on the Real Steel website, it's 10/30 Edited May 23, 2023 by Phill S Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted May 23, 2023 Share Posted May 23, 2023 Yeah I did Good you have the better pump, though I am now struggling to find figures do it, I believe they are different to the older style. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted May 23, 2023 Share Posted May 23, 2023 Ah, here we go, some info from Rave: So yes, around 40psi even on the crank driven pump. Think the PRV is a bit easier to access on these though? Quote Link to comment Share on other sites More sharing options...
Phill S Posted May 23, 2023 Author Share Posted May 23, 2023 I'll whip it out today and have a look at it... Just for the record, here's the cocktail recommended by Real Steel that I have used: Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted May 23, 2023 Share Posted May 23, 2023 Not to cast aspersions on your gauges but what does it show if you put 40PSI of air pressure on it from a compressor? Would not be hard for a sender-gauge mismatch or dodgy wiring to throw the reading off, and that's a far easier/cheaper answer than chasing imaginary engine issues!

Bowie69 Posted May 23, 2023 Share Posted May 23, 2023 Agreed, worth testing the gauge... Quote Link to comment Share on other sites More sharing options...
Phill S Posted May 23, 2023 Author Share Posted May 23, 2023 It was a dodgy earth on the Pressure gauge. Having sorted that out I got a reading of 2.8bar at around 2,500rpm, and with a small step input on the throttle a little wavering while the prv did its thing - same the other way about, a small step back down. Happy bunny time. Now to sort out the chaos you see in the pic above and dress the engine in all its finery... 1 1 Quote Link to comment Share on other sites More sharing options...

When I get to that stage I'll pat myself on the back as it'll be almost there. Right now that stage feels a long way away... Thanks for all the posts about your experiences and challenges. You'll probably save me a lot of time and visits from Dr Tourette. Quote Link to comment Share on other sites More sharing options...
