Yes, would think so. With the ZF the diff is dropped in from above/below so can be fitted either way around.Quote:

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.
Dave
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.

Ah, hang on, you're not using the Toyota engine, are you....forget what I just said! :)

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

The SC I had on a Honda K20 in my Lotus used a air/water charge cool system. Small cooler core after the SC which was connected to a rad at the front of the car and used an electric pump to circulate the fluid. Worked well, even though the SC was actually being 'over driven' and so stuggled with efficiency at high rpm.
Still, it managed to get close to 380hp from a 2 ltire 4 pot!
Neil Simons used one of these on his turbo-nutter car: https://www.chargecooler.co.uk/. Worked really well IIRC
I did a DIY job on my supercharged car. Grafted a cooler core from a Jag V8 into a spare Alfa plenum then had the coolant pump and a motorcycle rad with fan, the whole lot under ECU control. I also fitted water/meth injection but it wasn’t really needed, charge temps never got that bad.
A water based system can potentially handle a lot more heat than an air/air intercooler but has the penalty of added complexity and weight. Another benefit of a water based system for a mid/rear engine is packaging of course, a small coolant rad up front is easier to deal with than a massive air/air intercooler at the back somewhere.
Well thanks a lott guys for all your comments, thats what i have always liked about this forum, fast and sensible comments. Really miss being around here.
I am going to try without anny cooling at all, i also will have an ECU ( Omex 710 ) with air temp, air press and knock sensors. Aiming for 300Hp with an 3 ltr 4 cil so hope it wil turn out OK. The charge coolers will need an extra radiator up front with all the plumbing etc. Don't want that if its not needed, space is limited as it is now.
Hi all, been a while since my last post. Build stil going on , blog on Facebook: https://www.facebook.com/Pims-Lancia...82898468405402
Looking for someone that has experience wiring sensors for an ECU. I have a wiring diagram so i know which wires go to which sensor. But at the sensor there is a choice on which spade goos which colour. F.I. the coolant temp sensor and air temp have 2 spades, which is earth and which is signal. Same for injectors, TPS etc.
Is there some book maybe or internet link? Have been searching only found a picture of an injector with the pin designation, see attached.
Any help appriciated
forgot the picture Attachment 19024
Hi Pim, 2 very nice Alpines for sale in the UK today:
Early A310
Very original A110
This is for the Thema/Integrale 16v (as well as some Fiats) engine Pim?Quote:

Also needed to be a 16 valve engine thats tilted to the right like the original 037. Its a Volvo B230 with a B234 cilinderhead, here attached to the Porsche Boxster gearbox.
