I just heard from my mechanics at Dynosport racing. They completed the supercharger install on my 2006 SI and it Dyno'ed at 249WHP. This from 188WHP after AEM CAI and Evo II Catback. I am going to pick it up in a few, so I will post the Dyno run and any install details when I get home.

Stay Turned.

 

Do you have the hondata reflash?

 

Ditto Put that dyno sheet up !!!! like I said in the other post I really hope to see around 275whp with the smaller pulley!! Let us know how much boost your running too!!! Thanks

I believe when you purchase the Comptech s/c you are also buying the hondata reflash specifically for an fg w/ a comptech s/c...

 

Cant wait to see your results

 

Thats more like it!!

 

Very nice but i aint giving up the great high rpm VTEC feeling no reflash or boost for me !

So you'll lose the VTEC power with the sc /turbo?

 

I think so it gets put to the lower rpm range so you get more midrange power but i think that defeats the purpose of having it. I want it up high where it belongs to me the mid range power is enough to get me going then i just punch it and enjoy. If full VTEC came on at lower rpm i would sell my car it just takes the fun away i think !

Stupidest thing I have ever heard you moron. lol sorry I never flame anyone but your logic is wack. More power is more power. Did you even look at that dyno sheet? No where do you see power drop off. lol sorry no offense just think about what you just typed please.

 

I can see what hes saying. Best way to conserve that 'high end' jump is by turbo... S/C is more for the low to mid, while turbo is typicall mid to high. VTEC is good, but for the N/A world.

 

TY for understanding what i was tryin to get at with a SC/Turbo your getting alot more power thats not the point. I like VTEC up high when it really screams and yes i have no intention's of going boost. It aint that hard to understand the guy that flamed me must have been high or etc read it twice if you have too very simple concept for most.

Thanks for sharing your results with the forum. Very interesting, very impressive.

I'm sure you know that people will be wondering how much you paid for this. If you don't mind telling, I am sure it would help people budget for it.

 

wtf?? no VTEC??

 

That torque curve is soooo much better...

Wasn't VTEC bumped from 5800RMP to 3000 or 4000RPM with the SC flash? If so, Type-Ek, VTEC isn't going to be as noticable, but it still plays a part (i.e.: MORE POWER DOWN LOW). But, yeah, kinda sucks that you loose that kick in the pants up high, but it also means you won't be having that VTEC dip in power like stock.

I'm 1/4 of the way to an SC... Here I come!

Regarding Vtec, I guess it depends on what you define "Vtec" to be. As I understand things (and I am no expert by any means), the stock SI motor changes cams, advances the angle (timing) and changes the fuel mixture at around 5,500 to 6,000 RPM. At 5,500 to 6,000 the engine reaches its peak on the lower cam and flattens out, than it switches to the upper cam. When this occurs, the engine produces a jump in power and speed. You feel it as a "jump", and all the sudden, the feeling of being pushed into your seat.

The term “Vtec” refers to the technology. The supercharge does not remove that technology, it only tweaks it.

Like you, I also loved to feel that "jump", and the feel of being pushed into my seat. What I did not like is that you only get that feeling in the last 2K of the power band. I also did not like losing that "push in the seat" feeling when I hit 5th gear. The stock motor still pulls in 5th, but not nearly as well as 3rd and 4th.

With the Supercharger, this change occurs at 3,100 RPM. The only thing lost is the "jump" in the beginning. Believe me, the “pushed in the seat” feeling is much greater and much longer with the supercharger. If you have ever driven a car with a rotory motor (like an RX7), you know what I mean. The power is much more linear. In addition, I don’t have to run the engine up at 6K to 8K for the extra power. The power is always there. Personally, I did not want the turbo for that exact reason. I do not want to wait till 6,000 for the extra power. I wanted the power up front and constant.

As for what I paid, the kit was $4,324 (includes tax). The installation was $1,200 ($90 was to recharge the AC). However, I had my mechanics go completely through the motor and drive train before installing the supercharger. Anything, anything at all, that was questionable with the supercharger, I wanted upgraded. The only thing they upgraded (or modified) was the fuel pump. They also choose to reroute some the AC lines for better fit and accessibility. This added about 4 hours to the installation time. Out the door, after everything, they ended putting 11 hours of labor into the car.

And please, I have plenty of money and spend it the way I want, so no flames on how I paid too much, or “you could gotten this for this”, or “that for that”. This is what I wanted, this was how I wanted it done, and that is exactly what I got. That is what is important to me, not how much it costs.

at least $4,000 for the charger. labor $600. Plus exhaust, reflash, headers, intake,
and dyno. About $ 7,000 plus a $22,000 Si. Wow a 240HP $30,000 civic.

Supercharge kit $3,995, labor $600. Reflash came with the kit. Kit was designed for the stock header and intake. Exhaust $600, but the supercharge works just fine with the stock exhaust. Car $22,000.

Nope, not seeing $30,000 there. Oh, the wph is 248.2, not 240. Once Comptech releases the new pulley upgrade I expect WHP will be more in the 265 to 275 range (for those who want it).

Anyway, this was the car I wanted, that's why I bought it. I did not want a 2 seat-er or I would have bought a S2000. I did not want an all wheel drive or I would have bought a WRX (which I also found very uncomfortable to sit in). Last, I have no desire to own a BMW or Audi (fricking things weigh 2 tons and parts expensive). I fell in love with the SI the moment I saw it.

The car I want with the HP I want = priceless.

Guess its all personal preference.

 

Hey dude i am happy for you dont get me wrong its that i am new to owning a honda and i just like the VTEC up high i am sure your very happy with the SC. You have a sick si now enjoy and drive it like you stole it !

 

Roger that, I love the car too. And I look forward to seeing what the smaller pulley will do for power.

 

Hey... I was close.

 

The Hondata reflash (and the SC Reflash) actually have a "VTEC window" instead of a hard swap over point.

They only swap at 3000 RPM at wide open throttle. At anything other than WOT, they swap over at the normal VTEC engagement point.

So that myth is put to rest . . . not only do you not loose VTEC, but now you can select when you want to hit it.

I believe all VTEC engines have a VTEC window from the factory. All the reflash does is lower the low engagement point of WOT VTEC.

As for those complaining about losing the VTEC "kick"... well that's just plain stupid and ricey. Honda may tune that little dip in power to exaggerate the VTEC engagement point, but all that does is give you slower overall acceleration. Also, the car still screams up high, only now you get the blower whine on top of it .

to Hondata for a torque curve that's flatter than Kansas.

 

Its ricey to want the high rpm VTEC kick you make me laugh thats why people buy these cars if honda didnt have VTEC it would just be another economy car with no ball's. I guess your still not getting the point 6,000rpm WOT own's some would beg to differ and that's fine but dont call people ricey for craving this high rpm sensation.

 

Eh, I'll agree it is a little ricy to want that kick in the pants at 5800RPM, but for me it's just the adrenaline rush it provides for me and my girlfriend coming out of a 20mph corner and timing VTEC to pull insanely to the next one. But with the SC, having that on-tap power with that awesome torque curve will be AWESOME, so I won't miss it
