Discussion
So, im pretty much decided to go down forced induction route for my 111R...
Many reasons why, but mainly to add some torque and daily drivabiliy as well as having more fun between the corners. Ofc improving lap results is good, but driver training is where the priority is for the time.
Remember, my car is a daily driver and sees a lot of track.
I narrowed my choice down to two kits, lets say for simplicity that both will cost me around $9k (~£5k) + clutch + lsd + accusump + installation.
The kits are:
Forcedfed 275 turbo
http://forcedfed.com/elise/turbokits/
Komo-tec 250S supercharger
www.komo-tec.com/product_info.php/products_id/400
Added weight is about the same, maybe ff is a bit lighter, but nothing significant.
Peformance as tested by independant magazines:
Turbo:
275 bhp @ 7 psi
200 lb.ft
0-60 4.2
0-100 9.0
1/4 mile 12.3
Supercharger:
260 bhp @ 6 psi
185 lb.ft
0-60 4.2
0-100 9.5
1/4 mile 12.5
Im am heavily leaning towards Komo-tec kit. Why:
1. Reliability is one of my main concerns. Komo-tec uses water cooling and runs lower boost. Also as far as i understand, getting turbo tuned correctly is a lot harder and more importaint.
2. Supercharger power delivery is a slight preference for me, its no big deal at 6-7 psi, but im more of a n/a or s/c guy. I aslo think s/c suits the car a lot better.
3. Peformance difference is the only turbo advantage, but its really not that significant, and i will readily sacrifice a slightly better 0-100 for improved reliability and durability.
What do you guys think?

I looked at both too, to act as an importer and fitter. Daniel at Komotec seems very straight forward but Forcedfed have sold more kits so have more in the market place.
One consideration is reliability. Komotec supply on exchange a recoded ECU, whereas Forcedfed up to now have used a Unichip piggy back ECU - best to check with John Modica to see if that is still the case before buying. Being a supercharged kit the Komotec takes longer to fit which is important if you are planning to fit it yourself. If you want it fitted, we could probably help.
