Hi all,

Does anyone know ERHLICH history?

Also Please let me know if we have an information by site on web.

Especially, my interest is for Lotus TC engine.

I’m study about various Lotus twin cam engine at that time.

Thank you.

Hiro :)

Erhlich? Or Dr. Joseph Ehrlich...EMC, bikes, F3 etc.?  Here's a thread on the latter:




The forum search facility should find you a few more.

Hi Richard and John,

Thank you for the information.

Oops, EHRLICH is right. I have the cam cover.

Now I have checked William Taylor's The Lotus Book.

Dr Erhlich seems to bought the two Lotus 73 F3 cars.

This mean He did swap NOVA motor to his own EHRLICH Lotus TC engine?

It will be first appeared his EHRLICH Lotus TC engine?
Coincidentally, I'm asking NOVA motor by another topic.
Kind regards,
Hiro :stoned:

My Brabham BT15 F3 MAE screamer, which I no longer own, had a Dr Ehrlick rocker cover and downdraft plenum chamber inlet manifold. Both these items were quite distinctive.


The fins on the inlet manifold were I believe to try to increase the inlet temperature to the ambient temperature, and not for reasons of cooling. In cold damp conditions after about 10 seconds at full throttle, ice buildup around the F3 rules regulated inlet restrictor (I think was 32mm)  would turn the fire out !!!  Not exactly what you want when at full throttle. When this first happened I changed everything not realising what was going on, coil, plugs, points condensor etc etc .. but then relaised that the water on the inlet fins after a race was from melted ice.


You can see the styalised E surrounding the MC which I am told stands for Ehrlick Motor Company.
