The kit includes several components, a sports air filter, stainless steel exchaust manifolds, a sports cat and a retuned ECU. Basically exhaust back pressure is reduced which allows the retuned ECU to take advantage of the superchargersss potential.
Yesterday I had the chance to evaluate the results over the 500 KM on the trip back .
My impression is that the system completely changes the experience of the car. The Evora S engine is, despite the supercharger, normaly a bit sedate, fitting with its Camry heritage. I always felt it was a bit asthmatic at high RPM. The Komo-Tec completely changes that, the engine now feels very lively at high revs, very similar to the high-RPM Porsche, BMW or Audi S/RS model engines. The difference is all the more obvious as the higher power is only above 4000 RPM, there is absolutely no change to stock at low engine speeds. It really makes fun to NOT to change into a higher gear, the responsivenes is so lively.
I had the chance to compare some acceleration figures, though traffic prevented me from checking what the new top speed is. However, i don't expect miracles here +15% HP shouldn't get more than 5-7% higher top speed - which would at least match the Porsche 997 figures.
I compared the speed figures (6th gear) with the numbers I got from my previous pre-Komo-Tec video:
- 200 - 270 KPH cut from 42 to 32 seconds - a 10 second gain.
- 240 - 270 KPH slashed from 26 to 20 seconds - an amazing 6 seconds
Sorry there's no RPM, we lost the OBD-dongle in the Komo-Tec shop.
The car I passed at 1:20 in the vid was an Audi S4, which is normaly impossible to pass with the Evora S. Normaly an Audi S4 can maintan the gap when he does pull over and will be able to pull back in when hitting traffi. Notice that I can actually gain distance over him, which means I'm continuously reducing the time gap. Finally he had to and let me pull by.
So, is the tuning worth the 3,690 €? For me it was an easy calculation, the Evora cost 70 K€ for 350 HP, meaning 200 € per HP. The Komo-Tec only cost 90 € per HP, so for me it was a bargain. The fact that the car feels much more sporty is the decisive advantage, Don't expect any difference at low revs, but at high revs its impresive - as the figures show.
Of course its too early to see if there is any impact to longevity or potential heat problems. From the feel and the fact that fuel consumption actually decreased I wouldn't really expect any problems to come up. I already had the likely heat problems on the standard car (clutch hydraulics and shift cables both overheated). I can't see why this would get any worse.
BTW. Daniel told me they are working on Phase 2, which should come sometime this year and which will be based on Phase 1, sothere is no reason to wait.
So, for me the only real question left is, why didn't Lotus set the engine up like this from the start?
