Elise SC Tuning

Is it possible to tune the Elise SC for a little more, I appreciate it doesn’t run an intercooler. Would it be possible to maybe fit a charge cooler?

I’m quite interested in the answer to this.

Lotus must have decided that 220 bhp is safe with no IC, but I wonder what the limit is in terms of cooling??

They haven’t released any performance pack type model so maybe 220 is the limit.

Gotham would be an option (which I am running) but not sure how you will find out how far you can push it.

Would be nice to have a back window to see out of

smaller charger on the elise chaps

But still makes 220 bhp peak.

Give Sinclaire a call, if anyone is looking at doing an upgrade it will be them

But still makes 220 bhp peak.

true, but what is the dyno plot like? Also the exige engine doesn’t run full throttle its limited in the ECU to 65 or 70%

That is true for the Exige S not sure if it is correct for the Elise SC…

And regardless of the throttle limitation, it’s the same engine developing the same bhp / boost, therefore the cooling requirement is the same. I expect without an IC, the Elise SC is on the edge of it’s tuning limit - i’d be interested to know if this is true though. Lotus must not have upped the power for one of 2 (or both) reasons. Not to compete with the Exige in the power stakes, or that it can’t take the heat.

As the SC uses a smaller Supercharger to get the same boost, so will be running hotter than the MP62 on the exige.

There was talk of a chargecooler in development, along the same lines as the pro alloy one on the Exige S, but I think with longer piping and mounted in the boot.

I think on the other side of the pond a few have been tuned, and I think this setup may have been available on the 220 exige last year on the Federal exige (i.e. not intercooler)

Not sure how you can intercool an elise supercharged as the supercharger is built into the Manifold.

I saw a VX220 at Anglesey today that had a charge cooler, Pro-Alloy I think anyway it was in the drivers side scoop with some other stuff going on under the bonnet to do with the rad. For the life of me I can’t think who did the job despite him telling me twice

Its not the fact of where to put it, its the plumbing as it were. As I understand it on the exige S the air passes through the filter and into the supercharger where it is compressed and heated, from there it loops through the U tube, through the intercooler, through the other U tube and then into the intake manifold. On the elise the supercharger is built into the intake manifold and not separate so the air passes from the filter into the charger which is already in the intake manifold so no ability to cool the charge inbetween…
Well thats how I understand it but then that could all be bollox

That’s how I understood it from the short peek I had under the Elise SC engine bay.

One solution could be water injection I guess. Something like an ERL aquamist

dunno!

It would be possible to CC it in theory the same set up (ish) as the honda JRSC but with a smaller charger, so the same cc options apply. If you are going to the hassle of cc it though I would change the charger for a 62.

So your point is that you cant CC it because you would need to change the charger, thus also change the manifold and so I am guessing the ecu, leaving you with totally different conversion

no you could use the same charger, its just that if you were really wanting more power I would change it for a larger MP62 unit.

How though when the charger is actually built into the intake manifold? how can you cool the gasses leaving the charger when they are already in the intake manifold?

fit the cooling core into it like the JRSC cooler

This may be a silly question but why is the Exige limited to 70% throttle opening ?
