Gentlemen,
Thank you Vaughan for your post!
For my fellow "anoraks", could you supply any close up photos of the Bendix 476090 pump please? Is it the same as this one:
http://www.2040-parts.com/-vintage-bend ... n-i540432/I was surprised to see 1/2" unions where I might have expected 3/8".
I have some practical suggestions to make to this hot subject...
Firstly, the weather for summer endurance events can be warm. The 2018 LM Classic was held when air temperatures were at about 36°C in the shade (probably 50-60° at the track surface). In 2019 the Spa 3H (not reputed for "outback" weather) in 2019 was just 2° cooler.
It would have been very interesting to know the temperatures reached by diffs in these conditions and to compare these to the recommendations of the oil and manufacturers of CW &P. My guess is that temperatures were off the chart and increased mechanical wear occurred.
Secondly, most of the fellows in E-types now have air-conditioned
sous-vêtements and helmets. Is this really within the spirit of historic racing?
[ I would suggest that driver comfort = health & safety and in certain conditions A/C should be authorised or the perhaps organisers should run the races at dawn]Lastly, there are the physical appearance issues.
(a) I have seen no trace of "TTR" side scoops being "homologated", but there is photographic evidence of use in period. The elegant OEM S2/S3 underside scoops and opening in the boot N° plate panel also fall into the same category.
(b) Lotus listed the diff cooling and dry sumps in period (in 1964) but this were apparently not homologated pre-31/12/1965.
(c) I have sketchy notions of the classes of the period but perhaps some Lotus elements on the parts list were "GTS" and others were in a "GTP" class ?
For example...The GT40 and 250LM were not "homologated" until Feb 1966...Perhaps if a scrutineer refuses a diff oil cooler on an Elan he will also be refusing these motor cars at the same time?
Many thanks to all!
Andrew
