Yes this is true. The 1220 is slightly more efficient then the old NV 1000, 400whp+ capable from either. The NV 1200 seems to be the most tried and true option so far with 500whp+ possible, I will be upgrading to this blower at some point. The 1500 in theory should provide 550-600+ but no data yet as the few that have this blower are still working out the bugs. downfall to the larger blower like the 1500 could be more parasitic/power loss out of boost, to run in the efficiency range of this blower its possible a built engine and or race fuel or water/meth would be required to keep the tune reliable. But really you just want to match the blower to the power/efficiency range you plan to run, every blower has its own efficiency range.

My recommendation if it were me, would be to find a complete used Comptech kit with Aftercooler for about $3k, or get a new SOS kit with the 1200 upgrade blower and heat exchanger

 

I like your spreadsheet. Don't forget to add $$ for installation ($1000) + tuning ($300) + gauges ($300). (Those are made up numbers to give you a ballpark.)

You haven't really given us a target hp level. Sounds like you're not looking for 400+. Based on that assumption, and your desire for midrange, I'll make the following statements.

SOT seems like a good solution for you because you don't seem to be looking for high boost and are concerned with reliability. Roots blowers give you the best low end & midrange but this kit isn't sized to make a lot of power at high rpm. I still sometimes think I shoulda gone this route. They didn't sell too many kits, but I have not heard of any failures either. You can still order kits from what's left of their inventory, just hit their website.

KW kits give you great midrange compared with centrifugals. I'm not clear on the reliability; there have been some issues with pulleys and some folks have had serious issues while many others have not. These are a great all 'round solution for making the S2000 more enjoyable. They're a nice balance between roots & centrifugal in terms of having power all across the tach. The last KW AP2 I rode in was quite impressive.

SOS kits are very popular now. My car is a lot faster than I ever expected it to be, though it could still use more midrange & low end. I'm saying that at 15.5psi on an AP1, so you can imagine that there ain't much going on at lower boost levels until you get to the upper end of the tach. This is a very satisfying setup if you intend to flog the car. Since yours isn't a DD, it might be a good solution.

From a reliability standpoint, the SOS/Comptech/Vortech units have a great reputation but there also seem to be an awful lot of people rebuilding their centrifugal SC or fixing problems recently. A good installation and tune are critical to reliability. I'd suggest looking at used Vortech / Comptech kits if you decide to go centrifugal and want to save cash. If you're buying a new centrifugal, I'd go SOS with the Novi 1200 and racing heat exchanger.

The challenge here is trying to interpret all of our opinions. Personally I'd say that for the Dragon, I'd prefer a SOT or KW kit so that the car would be quick no matter what gear I was in. Other folks would say just use the shifter and select the proper gear and a centrifugal will give you all the power you need. On a track (that isn't so tight), I'd lean toward a high boost centrifugal to really enjoy the high end power.

 

Thanks for the ideas & reference points. My one concern with getting a used kit would be wear & tear which is hard to determine over the internet. But it has certainly crossed my mind. I see all these HP numbers, but keeping in mind this car will be otherwise mostly stock, would the 1200 be overkill vs the 1220? What is reasonable HP for bulletproof reliable long term use on a stock motor?


I lived & died by spreadsheets for many years. Can't go without one these days. The tune price crossed my mind, but I decided to leave it out as any kit would require some. I will be doing the install myself. Having done clutches, engine swaps, engine rebuilds on Hondas for the last almost 10 years, I'm pretty confident I'll be able to handle it. Being a second car I have the luxury of taking my time with it as well, which certainly helps. Gauges hadn't really crossed my mind - good call.

As far as target HP, I'm just pissing in the wind if I tried to say anything. I've never ridden in or driven a high power S, so I don't have any point of reference. I know I want it to go as fast as it looks & feels like it should go, which is a good bit faster than it is. 400hp almost seems excessive to me, but if that's slowly built up on a centrifugal it's a whole different car than 400hp on a roots.

I thought the point of contact for SOT superchargers was Static X Motorsports, but their website appears to be down so I figured they were out of business. Just noticed the SOT page is still there so I sent them an email. I really have always had more interest in this kit than any of the others. At the Dragon, you can't always just "use the gears" as I don't like to mash down into 1st. And you can't beat the proven reliability of the MP62, coupled with their relatively simple kit design.

Thanks everyone for the ideas

 

I have one of the original SOT kits. I will be installing it soon. I was looking for a stoplight racer in the S2000, so I have a stroked 2.4 liter motor and the SOT kit. I will be using KPro with it as well.

 

So traction/tires, diffs and trans are where most of your money will be going in the future from here on Should be a blast of a ride. I want to see some good 0-60 time posted from you.

 

three days and no response from email to SOT or PM to MugenRioS2k

when is the last anyone talked to one of them about the blower?

 

i am looking at vortech v3 self lube kit, and read some feedback that the self lube technology doesnt last and have issues.
i wonder it has anything to do with install or tuning

 

Self lube blowers is a great idea in theory, but I contribute all the premature failures do to lack of lubrication. they only hold 3oz of oil, which to me seems completely ludicrous to withstand the rigors of heat that these see. A filtered, and recirculated engine lube of 6q is going to do a much better job. if it isn't broke don't fix it i say.

To the OP, if you looking to get your s2k in the real of where you feel it should be as far as power prows but yet still retain much of the reliability it did from the factory, the best balance there in my experience is right about 350whp/10ps with a nice Comptech or SOS kit with large/upgraded heat exchanger. Can you go more hp then this and still retain your daily reliability, absolutely, but i feel after this 350whp/10psi level, it starts becoming more crucial how you drive your car and how its tuned. The rear end,clutch and trans are weak links after this point. So if you want to play it safer, stay under 400whp until you gather exactly what your potentially compromising and how your power under this feels to you. You may be totally thrilled with 350whp. It is a hell of a nice bump from stock that should put smiles on your face with every drive.

 

I see, in that case the Vortech V2 Kit will actually be a better system than the V3-SL since the V2 will last much longer than the V3.
I also read alot of SC failure from the V3 setup, which really bothers me. Or the V3 are more prone to fail if they are running at higher boost?

 

Assume I do go with Comptech or SoS kit at around 350 hp mark. Is it worth the additional cost of going to K-Pro, vs the included electronics?
