aka 07 Elise R go Supercharged project â€“ VF kit Stage 1
aka The Elise Lotus â€˜shouldâ€™ be making
Well I kept it a bit quiet but the supercharger upgrade to the Elise R is fitted , tested and complete. The results so far on the road, well Iâ€™m totally chuffed and a very happy man and I now have a Lotus induced headache from the excitement of driving it 🙂
The cars just ticking over 12,000kmâ€™s now so it is still feeling fresh and new but like all owners, I yearned for a bit more power & torque from my little Elise.
Time for some forced induction!
The back storyâ€¦.. After looking around for nearly a year researching all the Elise supercharger kits available, Katana, BRW, SSCâ€™s OEM based kits and becoming very very close to trading up to the Exige CUP 260, I finally drew down to the VF (thatâ€™s VisionFunction) kit jointly developed in AU and the US.
Vision function currently produce Stage 1, 2 and in the works stage 3 kits for the Lotus Elise R, Exige customers wanting a bit more power than is on offer from Lotus but I went with the Stage 1 kit which provides more than enough power and torque levels (see below).
After the order was in with Turbo XS team in Hornsby (the licensed kit supplier and installer for VisionFunction in AU) they promised the kit would take 2 weeks to fit.
This time was mostly down to the ECU having to be posted to the US for the legendary (well on the international internet forums level) Charlie X, to work his code onto the unit and post back to AU. The actual physical parts of the kit only takes the guys a few days to fit and its all rear body clam on work.
I should say what is in the kit, well all the details and technical data can be found here www.visionfunction.com but the kit contains:
- Eaton MP62 Supercharger (same as used in all supercharged Lotus Exigeâ€™s, not in the Elise SC)
- Custom Intake Manifold
- Intercooler (tests show 50% lower intake charge temperature, very important)
- New fuel Injectors (440cc)
- Charlie X Custom ECU Reflash
The kit cost all up $13,000 which included all labour, posting of ECU to the US and back, and 2 years parts and labour warranty. The guys at TurboXS kept to their word and the car was ready in a little under the 2 weeks they said. So far Stage 2 kits have been fitted to 2 cars in Melbourne but I am the first customer to have a Stage 1 kit fitted in AU. The kit produces a fairly hefty increase in power, here are the figures:
At the crank = 219.98Kw (295hp)
At the wheels = 183.82Kw (246.5hp)
The day before I picked up the car the guys took the car to be Dyno tested to do a before and after comparison, hereâ€™s the results and a video they made:
On the graph above, Red is the old power and
torque outputs, Blue shows the new.
I picked up the car today and so far have driven it for just less than 100kmâ€™s around the city to run it in a bit. First impressions are the car goes as hard as the Exige CUP 260 did when I tested it 2 weeks ago, I’m serious. 1st and 2nd gears are just over in seconds and are really quite scary. Car weighs in at 885kg with no driver so 0-100kph should be a clean 4 seconds if you know how to launch it correctly. Pushing hard over slightly broken tarmac, the traction control light blinked a tiny amount as you feel the rear tyres fighting for grip to put the power down.
Last weekend a few of you know I was lucky to have a Porsche GT3 for the weekend. The Elise now feels like it pulls the same if not actually â€˜quickerâ€™ to 100kph now and over that nearly as hard as the GT3 does. I feel the chassis would start to not cope so well if more power was put under the hood, I dunno.
Before and after comparison shots, the installation is neat & tidy
New air intake system
The guys were very helpful to make up some supercharged badges that I supplied in JPG format to them, this was an unplanned item for them and they happily obliged, finishes off the car visually quite nicely:
Supercharged Logos I put together in Photoshop
and they applied to the car
Oh and I have not mentioned the sound! The mashing of the superchargers gears as it chomps up the air makes the most incredible and crazy sound! Pushing the accelerator to the floor there were pedestrians hearing it coming and thinking â€˜what the hellâ€™s that soundâ€™. It sounds a lot like when a Jet plane is on the runway throttling up its engines, just crazy. It is FAR louder than the MP62 sounds in any of the standard Lotus supercharged Exige cars, it must be the freeâ€™er flowing air intake system I would think.
I am looking forwards to getting the thing out of the city and letting it stretch its legs to really see what nearly 300hp and under 900kgâ€™s of weight feels like 🙂
As the VisionFunction.com website says:
Head turning looks, CHECK!
Phenomenal lateral grip, CHECK!
Eye ball yanking braking, CHECK!
0-60 acceleration of a Porsche 911 Turbo, CHECK!
Sanna says after a drive â€˜yeah it goes really fast!â€™, Damien says â€˜It sounds Good!â€™
I will check back in once Iâ€™ve got a few more Kmâ€™s under its wheels 🙂
