Thanks for all the replies!
I live at altitude (~4500ft) so I was considering the supercharger. After doing some more research it looks like the REV300 would be fine for me power wise. My only concern with it is how necessary is a different clutch? Could it be "downtuned" as it were to not produce a ton of power? I would like to avoid going down a rabbit hole of having to replace a ton of stuff, and I don't want a lot more power in the car since it's not tracked or autocrossed just driven for pleasure. Also it's low mileage (just under 9k)
Regarding the Torque 200 tune I've seen mentioned: Unfortunately I can't drive a car with it but I do like the concept of the tune giving it a bit more torque. I just don't know enough about it unfortunately. =/
Incidentally I took the hardtop off this week and it's SUCH a blast.
Thanks to everyone who replied, you've been super helpful.

It has been reliable It never broke down on me. I have about 15,000 track miles on that car, that is a LOT. That's a couple of hundred hours near redline. When you do that, bearings wear out, cylinder tolerances get looser, but the car still runs, just down on power, so at some point, you decide to rebuild. The joys of tracking...
My point is that the engine never blew, never overheated, with a supercharger that was used quite heavily.

|me73||@Jamari - why not drive the car as is for a while and get to know it before adding power. If you get used to driving it on cam you may find that the car makes plenty of power as is. It's an incredible car as is.|

Since I live in the fascist state of CA, I added the factory supercharger many years ago. While people may pooh-pooh it, it changes the character of the car completely. All of a sudden, you have mid-range torque, even though the high end doesn't feel all that much more powerful. 2nd cam kicks in at 4400 RPM, and not 6200, and the transition is absolutely seamless, just the noise changes, which means the crossover point is tuned correctly.
Since I installed my factory SC about 8 years ago now, I've racked up ~13,000 miles on track with this thing, and it's been completely reliable the whole time. I've done two engine rebuilds since stuff wore out, but the S/C is still working great.
So, even if you get the factory SC, you will love the car, you will just spend the most money to get the least additional horsepower

You are correct, for a quick street car, supercharging is great! Especially if it came from the factory with a supercharger (yeah - all 238 U.S. Elise SCs).
If we are talking maximum performance, IMO, turbocharging is the only way to go.
A turbochargers thread would bring some opinions. LOL
Sorry, no trades.

SC vs. NA
I own two 2011 Elise SCs. Both have Cup airboxes and Lotus Stage 3 exhaust systems. Otherwise they are stock.
The 2011 Lotus brochure states a 0-60 m.p.h. time of 4.3 seconds and 0-100 in 10.8 seconds for the Elise SC (145 m.p.h. top speed with the hardtop on). My cars might be slightly quicker, as the Stage 3 also saves 12.3 lbs. over the stock exhaust system.
I don't race my Elises, so I don't care about heat soak or what the ultimate supercharger setup is for track Elises.
I agree with Robocop310. My SCs are fast enough for me.
In fact, they are the most fun cars I have ever owned (which is why I recently bought a second one).
The factory supercharger spools up incredibly fast and it doesn't care what gear you are in - just mash the pedal and it goes. What's wrong with that?

Again, truly not trying to push a particular point of view, rather trying to share as someone that has done all of these things and trying to explain the nuance of why I landed where I did. I do agree if funds are an issue AND someone is confident that MP45 power is all they would ever, ever, pinky-swear want. Then do the reflash with some headers and be done. Unfortunately, there is never enough power for me. RevX is the result of me badgering Phil for a couple of years....

As you guys know, We've had about everything on the car over the years: Turbo(hated it), BWR Non-IC SC kit, Custom Whipple setup, and now the TVS400. TVS400 is night and day difference. Just feels like a big motor. 11 sec 1/4 mile car out of the box.
On the emissions front, we've passed in AZ multiple times, which at one point was HARDER than Cali. Now they are the same, plug in the OBDII, do a visual, check gas cap, done. To the OP, check your local laws. CARB is by its very nature, california specific. NV has their own stuff, but if I was guessing, same as AZ. People that say just chip the NA car, just haven't driven a TVS400.
Full disclosure, we sell the TVS400. We have 3 Eliges all have blowers.

I have an 05 with a factory supercharger. Picked it up used on this board for 1500 bucks. Installed by the local dealer for 1500 so all in 3K with new factory ECU flash, installation warranty and dealer paperwork. I love it, if only for the whine. Actually gives quite a useful down low torque boost. Different strikes for different folks I guess.
My motivating factor was long term support. So many aftermarket kits have come and gone in the last 10 years and parts support can get dicey.
I am not tracking this particular car, so for my purposes, it works out great. Plus as mentioned above, you can't go wrong with factory parts at resale time.

If one worries about resale, the factory s/u is usable in all US states; others are not, esp in CA.
Chips such as Torque 200:
In 2006, I got a (non-BOE) chip for Elise. PES not in that business now.
The most salient benefit was the elimination of the large valley before cam changeover. (IIRC, a ~20 hp gain at that point, but not at other rpms.)
It was quicker in my testing: 3500 rpm to redline, same road and gas level; 1 second quicker. Pretty good.
2 yrs ago, got the BOE 300. No other changes, e.g. stock exhaust, but BOE uses their foam air cleaner.
The thing to remember about superchargers is the instant torque they deliver, down low.
This, a pleasure and easier to drive.
BOE shows the TQ200 @180 hp/136 tq (which may mean the hp at crank is ~212)
That is better than my old chip, but that tq is still pretty anemic and, worse, peaks at 6900 rpm.
Even the Exige S managed 159 tq (@ crank, ~187?) at a reasonably low 5500 rpm.
I cannot accept that 2 equal cars will perform the same using TQ200 vs factory supercharger.
I've said before that butt dynos are of no use to us. Try clocking your car before/after mods. I chose 3rd gear because it was long enough to minimize tiny timing errors and didn't want to introduce errors by incorporating any shifts.
I will post my new time (same road) soon.

|daz01||Also... anyone tell me where the intercooler on the Elise go? The Exige back is bigger and blocks the rear window. How is it fitted in the Elise ?|
|05-15-2019 12:15 PM|
|daz01||The Katana is out of stock when I asked about buying one.. looks like they are re-designing it? Worth awaiting on that?|

|Robocop305||I'm satisfied with my factory SC for now. I don't track or race my car. I may change my mind if I decide to track it.|
