Well, I guess it's time to put in my two cents worth. Mosinu I'm not sure where you got you information but it sounds fairly textbook to me without much hands on experience.

First of all the engine in the S2000 lends itself to quite a useful performance gain with supercharging and only 6lbs of boost. One hundred horse power (100 hp) at the crank. I'd say that was about a 25-35% gain over the stock baseline for $4,895.00. Not bad! Not to mention considerably less long term strain on stock engine parts. For me, I'll leave the expertise to the guys at Comptech. Let us take for example, turbocharging for a price of $10,295.00 for similar performance, hmmmm! Or better yet, let's consider keeping it, without forced induction. That would leave you with the option of eather buying a stroker motor or building one youself which. Figure, $10,000.00 to $12,000.00 to do it right. Now that's for the engine alone. I didn't say anything about the drivetrain. Throw in another $7,000.00 to $9,000.00 for that. Grand total some where around $18K-$20K. Expertly ported and polished head $3K or so. Now here's the tricky bit! Put it all togather and you still won't get the car to run in the low 11's or high 10's and be reliable for everyday use. OhI almost forgot, I didn't include the electronic engine management system. A good one, 1.5K to 2K. Out of the reach by most automobile enthusists.

Honda has produced an engine specifically design to produce it's power at a much higher rpm range. Without losing it's economy at lower rpm's. This means that your gonna loose out some where. If you want a 9 or 10 sec torque monster drag racer go buy something with 8 big holes. Comptech has produced a supercharger kit based on all round efficient streetable performance. Remember, these guy are in the business, your not. You've completely missed the essence of what the car is all about.

NOS and extensive internal modifications are not cost effective nor condusive to long term use. Never have been and never will. I'd say without a doubt that the Comptech Supercharger gives the most performance gain per dollar.

The other thing you mentioned is a compairison between a centrifical blower (Comptech) and a roots type blower. (Jackson Racing). They don't even market a blower for the car. I really doubt they will. Centrificals don't require large amounts of boost because of there direct driven design. On the other hand (Roots) type require more boost to produce the same power due to their power loss, being belt driven. This is one of the reason Jackson hasn't decided to produce one.

Frankly, I don't think you've had enough experience with this type of engine. Most of the things that you've quoted are not practical for the street, let alone the strip. The S2000 is not a strip car. If anything the engine has been over engineered by the factory. Proof of this is in the minimal gains with bolt on parts, is., header, throttlebodies, exhaust etc. Only thing I can say is" Good Luck" and I hope you got mucho $$$$$$'s. One other thing, if you bet this friend hard cash money, I'd go to the bank, draw it out and give it to him now, before you spend it on the hp parts. You aren't going to make the S2K do low or 10's at least not without making it totally street illegal.

Oh yea, you need to quit watching the Fast and Furious it's giving you dillusions of grandure. IMHO

Lastly, you said something about shaving the heads to lower compression in one of your threads??! Shaving the heads raises compression. Reduces the"squish" area that produces more compression. I think maybe you were mistaken. Common practice in two stroke and four cylinder motorcycle racing. ah, er *cough* to RAISE compression.

 

Fine! Supercharger it is! LOL

 

Not to state the obvious, but take the $5,000 and buy a 93 to 95 ZX-1100D and run high 10's all day long totally stock...

Why try to defy physics with a 2 liter 4 cylinder? Enjoy the car for what it is, one of the BEST roadsters ever made!

 

OK, I've never modified a car b4.....but $5000 for a SC vs $1500 for Nitrous.....sounds like nitrous is the better deal?

 

That's exactly why. Why do people climb Mt. Everest? Why do people skydive? Some people like to be challenged, and to overcome adversity.

Even though the Nitrous Kit is cheaper, you also have to consider that when you buy a SC, it is bought. When you buy Nitrous, you have to refill the tank all the time. I know if I had nitrous on mine, i couldn't resist using it, and would have to fill the tank EVERY day. I think it's about $35 to fill a tank, so that adds up pretty quick.

 

you could always just do both.

 

Dang, SC versus stock? The SC sure does make a big difference!
