As for the pressure drop, the lines are fairly good size and probably more than handle the oil flow. It's not like there is a huge volume of oil flowing through the system. As the volume/velocity of floe goes up, the pressure drop would be significant, but again for our engines, the flow isn't really that high and it's probably sized about right (putting a bigger sized hose wouldn't have been a big deal for the factory if had been necessary).

And everything can be improved upon. It's all a matter of what an improvement in one area causes what effects in another (i.e. more cooling = more weight: etc.). And cost is always a trade off - it's one of the reasons that we drive Elises instead of Enzos...
I agree with you, Tim. They were on a budget and a tight schedule and compromises were made here and there, no doubt...

It sounds like you think that it may have been a cost and/or availability issue as to why we don't have a sandwich cooler?? That tends to be my thinking. I wonder how much weight could be saved with a simple sandwich cooler? 10-15 lbs?

Regarding the pressure drop, it would be interesting to measure it. We may be surprised.

I thought I read that the cars with two coolers were running as low as 180 temps at the track, although I can't recall where I may have read that. That's why I asked...

Best,

Phil

Whoever thought working on a Lotus is hard, clearly hasn't tried it. Pick up a wrench and get some grease under your nails
