Has anyone heard anything of Komo-Tec supercharger?

I've contacted them but they won't even send detailed photos because their afraid someone will rip them off...How can you sell a product if it is a secret.....

sleepless · 02-26-2006, 11:14 AM

1 - too expensive
2 - overly complicated and heavy (water/air intercooler)
3 - need to see a dyno chart to see how well the centrifugal SC works on this engine

MattG · 02-26-2006, 11:21 AM

That's a very nice looking installation!

never heard of them...are they some kind of cccp tuner shop cranking out superchargers?

From their site, they look like a pretty professional organization - though until some Elisetalkers have actual experience we won't know for sure. Another picture of their supercharger install...

it does look slick, but never heard of them

I'm guessing it's the Rotrex belt driven unit from Denmark. I sent Komo Tec an email to find out. The Rotrex is driven by a viscous fluid so it's very quiet. It has high efficiency, supposedly as high as 80%. It's very small, about the sized of an ac compressor. If that's what the're using, it's a good deal. I think the kit would be expensive with our dollar conversion.. And of course, what about our ECUs. The supercharger alone in the US is about 2k. Be a hero and make your own setup!

MikeW · 02-27-2006, 09:30 AM

I emailed Komo Tec and asked what king of supercharger it was and if they had the capability of programming a wire/throttle '06 ecu.

the reply:

Hi
we didn't really have explicit pictures because we didn't want to show too much to the competitors yet. We map the ecu ourselves, but not with the Lotus tool.
Daniel

So I didn't really learn anything but I'm betting it's a Rotrex unit. Maybe in time they'll get more informative about their setup. Since there's a lot more ecus that are the earlier style in Europe, I would guess they may be content with a kit for the '05 and earlier cars and will take a while to figure out the '06.

This is just stupid. All it takes is once person to buy this kit and then post pics of the install to the web. The company shouldn't be worried about that. They should be worried about selling their products based on their merit, whether it be support, quality, driveability, reliability, etc. If they can't win sales based on that, and have to worry about competitors copying a similair design, I'd steer away from them.

MikeW · 02-27-2006, 10:43 AM

At the US vs Euro price difference, there won't be anyone buying here soon. I was very interested if it was a Rotrex. I've read about them and had tried to buy a worn out one on ebay for trial and error for an 24 valve dohc v6 transplant in another car. The 6 rib serpentine pulley and the relatively small size an effficiency got me interested. This could be just the thing for the Lotus. In the defense of Komo, I suppose they want to get some definite orders and secure their position in the market before everyone else copies them.

®ob · 02-27-2006, 11:30 AM

True, but all it takes is 1 order and they might as well show all the cards.
If they don't, the new owner will for sure.

fzust · 02-27-2006, 11:41 AM

1. Obviously they are very professional because they all wear overalls.
2. Since when is a centrifugal SC known for low-end torque? ).4Bar is 5.88psi at max RPM. Thus at 3000 rpm it is 3000/8500*5.88= 2psi. Now you take out the extra load on the engine and the 80% efficiency....

Buz · 02-27-2006, 11:44 AM

Centrifugal superchargers have better top end power than roots or Lysholm at the expense of low end and mid range. The are really a belt driven turbo. I would go roots or Lysholm on the 2zz for driveability.

Val · 02-28-2006, 05:10 AM

Ok, here is some data

evomind · 02-28-2006, 07:36 AM

theres always tradeoffs when comparing different types of forced induction, or diff types of s/c.
this is a high revving motor, that is where its strength lies. if u wanna make it a midrange monster, so be it, but thats not where this motors strength is. its strength is high end power. i think a centrifugal s/cs are great and fit our application real well. keep in mind u WILL have more midrange power to go along with the top end.
keep in mind we rev our motors to 8600 sometimes....u may be asking a lot of a screw type s/c to make power for u efficiently from 1500rpms (seems to be where some of u want it) all the way to ~8500rpms.

Val · 02-28-2006, 09:34 AM

Well, i am not an expert, but the power curve looks like one of the best ive seen so far. Very linear.

sleepless · 02-28-2006, 09:40 AM

Actually, it looks a little odd right around 7500RPM.

Actually, yeah... hmm, didnt pay attention to that

Eyelise · 02-28-2006, 05:40 PM

I've said from the beginning an air-water intercooler makes much more sense in our Elise bay. The install looks the best I have seen. Looks like it was meant to be there.
