[QUOTE=ProtoTipo;45400]That looks like the right one Chris.
I've only seen them on eBay before rather than on a website but the location and images look correct.

Yes, would think so. With the ZF the diff is dropped in from above/below so can be fitted either way around.
With the UN1 the casing splits down its centreline so I also think it can be potentially be fitted either way although I've only ever seen the box fitted in the OE diff down manner.
With the Porsche and the Audi then access to the diff is through a plate on one side so I assume that this means the crown wheel must always be on this side so they are not reversible.
Craig, thanks for explaining it for me! All so obvious when you say it but beyond my wit to work it all out for myself.
Why lots of DFV F1 cars have their gearbox sump plugs facing upwards:
Build stil going on, i have a question about superchargers. I know some of you use a Toyota V6 with a supercharger. Does this setup have a kind of air cooler. I tried looking for some Lotus supercharger pictures but cant see a cooler?
I am strungling to make a discision about using an intercooler but that takes a lot of space at the rear, and its not quite 037 ( see picture of intercooler mock up. If i could run without that would be the easiest. Than another thought is to use water injection like the original. I know Saab has used it to before.
Any thoughts, help.
I am using an Eaton M90 from a jaguar spinning 12.000 rpm, not sure if thats any use :rolleyes:
Best regards to everyone, Pim

Hi Pim,
The lack of a charge cooler on the Supercharged Toyota V6 is the limiting factor as far as ultimate power gains is concerned, even in the Evora they suffer from heat soak.
The latter Evora S410 uses a slightly bigger Supercharger and more importantly now has a charge cooler, I think if you can fit one in it would be a good idea.

Thanks for the comment Dave, so it is doable without a cooler but can create heat soak ( less power or damage???? ).
I did think about a charge cooler but this would mean an extra cooling radiator, hoses to the front of the car. And like the intercooler very close to the exhaust pipe
I am seriously thinking about water injection, modern BMW use it: https://www.autocar.co.uk/car-news/i...ther-cars-2019.
But how much power do you actually want? Standard Lotus figure for the non-chargecooled cars is 345bhp, but you can get Komo-Tec upgrades to well over 400bhp if you want, and none of the extra complications of plumbing of extra radiators or water tank for H20 injection.
Ah, hang on, you're not using the Toyota engine, are you....forget what I just said! :)
Hi Pim,
My experience is limited to the Toyota and aftermarket ECU combination. To answer your question, I guess both.
As the inlet temperatures rise they have to change the ignition timing to prevent knock and this reduces the power significantly but protects the engine from pre-ignition.
I have inlet pressure and knock,inlet temperature sensors to provide the information to the ECU and it is set up to be on the "safe" side to protect the engine. I'm pretty sure they mentioned something like a 5bhp reduction for every degree of increase in temperature over a certain limit, but don't hold me to that.
To give you an indication, after an initial warm up the first run on the rollers will see 380phb+, after a couple of runs heat soak reduced that to around 345bhp so quite significant.
I have thought about water injection and that maybe something I add at some point. On a cold damp morning you can feel the difference as you do get more power, in just the conditions when you don't want it:D
