What's available for the evora s. Can you still get the radium kits?

BOE (US) or Komotec (GER)

Radium isn't produced anymore and had a tendency to mess with AFR - which is a terrible thing.

The Komotec is expensive compared to the BOE kit and the results are the same. The manifolds are the way to go for good power gains.

Komo-Tec probably had to do a lot more testing to be able to sell their kit.

From memory intake modifications on the Evora are a tricky business - the engine is extremely sensitive to them.

Correct - having lived in Germany for six years i recall the words "tuning components have to carry TÜV certification" which means top dollar beaucoup - but a well engineered product none the less.

Radium haven't produced their kit for a long time but they do occasionally come up on eBay - of the two remaining kits i'd go for BOE because i don't have the £699 the KT intake requires.

Although i have been warned by Essex Autosport to avoid fitting an intake kit on any Evora.

ETA: Correct price from Hangar111 of KT intake. http://www.hangar111.com/shop/komo-tec-lotus-tunin...

Actually after import tax with the BOE and shipping the KT is pretty much bang on.

Essex autosport carry out the work on my s. They said that to me as well but it was caveated by the news to map the ecu if one was fitted. If i end up keeping my s a while i will eventually go the kt route as they are a proven tuner.

EA have mapped my NA. I think the KT kit for Stage 1 is around £1000 for the NA to get the intake mapped in by them.

Thanks guys I think to be on the safe side I would probably go with the komotec.
There seems to be a problem with fueling on some of the other end kits.
Has anyone fitted one on a S and was it worth it.

Not had one fitted but it's 1500 ish for 375ps. I guess the question is, is that vfm for you. What I like about kt is you can upgrade in stages to help the wallet. I imagine you would feel the power boost and the intake noise should be great as well. Listen to me talking myself in to it!

I am talking myself into it to.But at £1700 would you be better with a Larini manifolds upgrade. I think these are around £1400.Then fitting costs.

Fitting coat being the key! Would probably. We'd a turne as well so again, not cheap when all totted up.

I had my Evora S 2011 fitted with the Komotec 390kit. This involved replacing the restrictive headers, the supercharger pulley, and a remap.

When I first got in the car I noticed it was much keener to rev and felt much smoother, and was definitely more lively at the top end. I also noticed a reduction in fuel consumption, so overall it was an improvement. Don`t think however the upgrade will be night and day different.

I then went for the 420hp upgrade, and again it was an incremental change, but it never quite lived up to expectation, I think largely because the traction control system wouldn't let it give full beans until you were in 3 figure speeds! I am interested in the 460 kit though because there is a hike in torque, but this will overload the gearbox if you do race starts all day long...sure it would be fine for most users though. It seems to work well in the Exige, but not sure if any Evoras have had this kit fitted yet...I might be the first?!

Is the 460 upgrade not an engine exchange job. I think this is a long way away from being ready to fit in our cars. A bit disappointing to hear the upgrades from komotec are not as good as expected.

If you do incrimental steps I guess it's not as life changing as doing the 430 straight away from 345hp.

No the 460 is not an engine exchange job.

I do think this upgrade will be the most noticeable because it has a big hike in torque.

I did not mean to give the impression that the differences were not that noticeable. They feel subtle because the car is so competent. I eventually sold my 2011S and bought a 2013 SR, and it immediately felt a bit gutless, so there was a noticeable hike in performance...you just quickly get used to it.
I am also lucky enough to have a company 2014 Exige roadster (don`t ask) and I have had that upgraded to 390 specification, and again I think it is a worthwhile improvement for not such a large outlay. The engine just feels freer and revs like it ought to.

Basically the 390 upgrade is good value, the 420 maybe a harder to justify and it was not so smooth, largely I think because of interfering electronics. I think the 460 kit is the one to really go for...they seem to work well on Exiges. However I am not sure if the electronics will interfere on the Evora...when I have mine done, after a bit of research, I`ll let you know!!

Nope, no engine internals are changed. (Incidentally, the cams can be changed with the engine still in the car).

The Ex460 'kit' is new intake, SC pulley, manifolds, remap and, specifically, a charge cooler. A new rad for the charge cooler is installed in the nose of the car.

Thanks for your replies guys. Some very good info from people who know about the lotus brand.
I will try the komotec upgrades and see how it goes from there.
As you say these small upgrades can make a nice increase in power. As if the S is not quick enough lol.
