I'm running the SOS kit with the Novi 1200 @ 15.5 psi. It really transformed the car. On a two-lane road, I can wait behind a semi @ 50mph until we reach a passing zone, drop into 3rd and stomp it, and the car just hurls itself forward. It feels like maybe 2-3 seconds and I'm at the top of 3rd, already next to the cab of the semi, and shifting into 4th (though I'm already moving so fast I could just coast by). A second later and I'm past him, starting to get back over into my lane. There's no time to look at the tach since I'm watching for oncoming traffic and it all happens so fast. This ain't no little Honda anymore! It's completely unlike anything a NA S2000 can do. The best word to describe the experience is "violent".

So, the top end power is just awesome. Based on my test drives, I'd say it's faster than an LS2 'Vette and maybe comparable to an LS3. Midrange is solid as long as you lower VTEC. That makes a huge difference. I've got mine at 4,500rpm right now and I'm moving it down to 3,000rpm with my next tune. Low end is noticeably better than stock (translation: the car never feels slow anymore) but isn't awesome. I'm hoping dropping VTEC lower will help that a bit.

The Novi 1200 makes a lot of noise, and the higher you spin it the more noise it makes. Mine is all gear lash and mechanical thrash; no cool whooshing noises or anything. It doesn't sound cool or sporty, just loud and mechanical. It makes the exhaust louder too, which compensates a bit. I rode in a KW AP2 once and those have more of the turbo whoosh sound which is pretty neat. The KW setup complements the F20/F22 very nicely and is a great kit for DD cars, but I knew I'd want more power so I went SOS and kept swapping pulleys until I had enough.

My other favorite thing to do is to merge onto a multi-lane highway from low speed, say 20mph when the other cars are doing 50-55. Let a bunch of them roll past you, then stomp it in 2nd and feel the car gather itself up and shove you back in the seat as it takes off. A few seconds later you're at the top of 2nd and about to shift when you realize that all of those cars (which were flying past you) are now moving back toward you because you're overtaking them. It's like somebody hit Rewind on a video of highway traffic! Really strange sensation, and very cool. This was my first WOT experience at this power level (on the way home from my last tune) and it blew me away. At first I was like, WTF? because it seemed like everything was moving backwards toward me all of a sudden. It actually took my brain a while to realize I had caught up to them and was moving faster than they were because it had all happened so fast. Never felt that before...

Oh, and the SOS kit is completely reversible. No cutting or drilling, yada yada yada.
