Okay been lurking for years had a 2004 that I kept stock sold and bought a 43K Mile 2007 S2k about 2 years ago and just did bolt on mods with flashpro been rocking that for a while but I am ready for some power.

I have owned a 2007 Roots Supercharged Civic Si that started out at 280whp and built up to 380ish whp then went to a turbo setup making about 450whp. Ran 11.8 @ 124mph on Stock Motor and Transmission. I also get to run a 2011 Civic Si Turbo for a local family owned car lot I run. That setup I am running 11.1 @ 129 and 133mph on Stock Motor and Trans as well making 550+whp

Basically I am wanting to build the s2000 to be capable of trapping in the 125-130 range in the quarter not that I will be hard launching the car at the track I know that the stock diff is weak so I do not plan on abusing it but trap is also an indicator of what a car can run with on the street and I'd love to trap 130mph.

Been researching and looking into the different Supercharger kits as I like the way they deliver the power keeping the characteristics of the car. I started looking at the Kraftwerks kit but it seems like a huge headache and probably 460 is the limit. For some reason the C38-91 blowers don' seem to perform the way the are supposed to on paper.

I have saw that one guy hit 520whp on a SOS Novi 1200 kit. So my real question is a SOS Novi 1200 kit with the smallest 3.0 pulley what can I expect to hit power wise? I can run 2 tunes one on 93 octane and one for 100 octane. I do not want to use E85. Also, what about the Novi 1500 that setup seems to only make more torque and broader curve not really much more power right?

Sorry for the long post and bear with me as I have a lot of questions.

TLDR: What is a SOS Novi 1200 capable of maxed out with 3.0" pulley and is there any real reason to use the Novi 1500

 

I dont think the N1200 is capable of trapping over 118mph. You will need 550whp+ to trap 130mph.

I only managed yo trap 120mph with 526whp. Thats wothout launching. I think i would need 600whp to trap higher.

But my car is crazy fast on the highway.

 

400whp is about 118
460whp is about 123
520whp is about 128
580whp is about 133

These are based on my personal experience at the drag strip and ofcourse dyno numbers vary but I ultimately dont care about dyno numbers. Trap tells me what I need to know.

526whp and only trapping 120mph means that was probably an inflated dyno or something else is going on causing a power loss.

So realistically can I expect to hit 500whp on the Novi 1200 with 100 oct fuel. Maybe I need to be looking into a turbo setup but I really pefer a supercharger power delivery.

 

Keep in mind these aren't pd blowers like a roots. Peak torque is at or near red line. So a 500hp n1200 will be noticeably slower than a 500hp roots blower or turbo.

 

Regarding the 1200 vs 1500 discussion, from what I remember the gains you net from a 1500 will be lost (and then some) due to the extra HP it takes to spin that blower. The 1200 is much more efficient and will yield better results. Also to note, the 1500 only provides 50 extra CFM at peak.

You mentioned you plan to max out the blower; are you also planning for a motor rebuild? Unless you plan to E85, I dont see how you can run peak boost (~20 psi) on 100 octane.

 

Ran 22psi On my 07 Civic Si with a custom M90 Roots supercharger. Couldnt get the temps down to make the exact power i wanted but was still an upgrade in power over my M62.

Also our 2011 Civic Si we pushed 21-22psi on 100 octane and trapped 129mph

From my understanding the F22 is strong like a K20... I have no problem running 20psi on 100 oct

 

I have a n1200 with a 3.0" pulley. On a DynoJet, it put down 492/319. That's with stock exhaust, e85, and AFR in high 10s:1 up top. I think the user, Ilovemyhonda1984, put down 511 on his 1200. He upgraded to a 1500 and put down 600whp. You can search for that yourself. If you're into drag racing, then you should consider going with a proper turbo setup. Also, I think the 520whp number you mentioned was on an Evans DynaPack.

 

Thank you! Not going to be into drag racing the s2000 just where my experience lies so thats how I put the performance into perspective. If I can get it supercharged with equivalent trap speed of 125 to 130 on the N1200 thats what I'm shooting for.

 

500+ whp is capable on both the N1200 and the N1500.

The n1200 will net you 19-20psi with a 2.8" pulley. And Sunoco 104 octane is all you need for that psi. Here is my list of mods before is started expanding on the SOS N1200 kit.

The n1500 will net you 4-6 psi more with the 2.8" pulley. With every bolt on mod performed you can get over 550-600whp. This is by going beyond on all other mods you can.

If you are planning on maxing out either blower unit then go for the N1500 blower. IMO

 

Thanks I would really perfer to stay supercharged rather than turbo on an s2000 just feel like the progressive power delivery is characteristic of the car. When I turbod the Civic Si it changed the car completely.

Can the stock AP2 valvetrain handle 22-24psi? I know the K20Z3 motors can. Id rather not have to touch the motor at all.
