Motorsport Elise
Discussion
Thought I would post a few recent pics and spec list of our original 1999 Motorsport Elise that has been developed over the years at JDR. The cars races in the Lotus Cup UK open class where we have found ourselves up against more powerful machinery like the V6 Exige's and Europa.
Basic run down of the spec is;
- 2.3L Ford Duratec race engine
- Hewland EGT gearbox with geartronics paddleshift system (Auto upshifts!)
- JDR designed and built engine mounting/adaptor plate and dry sump system
- Specialist components ECU
- New Motec colour dash, pdm power control unit and can panel
- JDR desgined aero package in keeping with Lotus Cup regs
- 2 way Quantum dampers
- All the usual bit and bobs such as quick fill refuelling, air jacks etc.

Am I correct to think the regulation in the open class is 285 bhp/tonne max power to weight ratio? If so, how do they calculate bhp from power at wheels? The reg says it's with driver; is it also with fuel and if so, is it a minimum weight the car must be at the end of the race?
Reason I ask is I also have a Motorsport Elise, but still run the Rover K-series. I wonder how I'd fare P2W wise in that class at 780kg for car and driver (empty fuel tank) and about 205bhp measured at the wheels?
Will, yes that is correct. Power is tested on a hub dynapack at Tdi in Thurrock. The weight has to be a total including driver that you will be at the end of the race.

We have moved to a fly-by wire throttle system this year, the main advantage being is that we can reduce throttle opening at the top rpm range to cap power but can still make very good torque and power lower in the rev range. I am sure you would do ok still with the K-series but in my opinion the Duratec is far easier to run and maintain.

Very nice. How much power is the Duratec putting out?
Due to the way the championship works with power to weight ratio we cannot run anywhere near maximum power so not really enough!

What is the regulation on what engines can be swapped into the car? Class I run in out in China says we have to have the original engine the car came with - hence I'm still K-series. How does it work over there?
That is exactly right Will with regards to power output. For the open class here you can run any engine under 2.3ltr. If you stay with the original engine you can have forced induction.. On a K-series however that would take a lot of development to get working reliably for 1hr+racesturbotoaster said:

Now thats an interesting second sentence for the future with my carGassing Station | Elise/Exige/Europa/340R | Top of Page | What's New | My Stuff
