pretty much if your just looking to have fun and get more power go with the sc and don't want to be the next TOUGE champion or be a highway roll champion and don't want to worry about boost spikes or spool up or part throttle fluttering that a turbo can sometimes give, if you just want to mash on the throttle the sc is for you, you'll have a very controllable powerband plus the reliability side of it to, if anything ever goes wrong just unhook the sc belt and drive


now keep in mind this is coming from a guy who HAD a comptech sc at 10psi and now sprays a 125 shot of nitrous on the straights ...in my opinion you just can't beat the n/a fury in the turns

This is nothing like vtec in a corner.

Vtec always comes on at the same time every time. Same with a s/c

With a supercharger if your @ 7000 rpm you'll be making the same whp each and every time you get on it @7000 rpm and you'll know exactly how the power will hit because boost pressure is set and always the same @ that exact rpm because the belt makes it so.

A turbo may be spinning @ 50,000 rpm or 100,000 rpm @ 7000 depending on prior throttle position. This will change how quickly the turbo will spool an how soon you'll see full boost. Could be instant or it could be .5 seconds. This is the nature of turbo design and how it is different Vs n/a and s/c in terms of throttle response.

Having said that. A supercharged setup is more predictable than a comparable turbo setup for the purpose of twisties and track driving.

I'd also like to point out that a turbo is more flexible in it's power delivery. So it's all about your end goal

I think you guys are TOTALLY over thinking how a turbo operates. You have FULL control over how much or how little power you want with the throttle, it's as simple as that. If you tuned for 12 psi you get 12 psi under full throttle and anything in between, depending on your throttle input, how can boost levels change from one corner to the next. The car will drive as fast and as smoothly as you want it to go.

If your argument is that the SC makes less power and is therefore easier to control than a turbocharged S2000, then I can certainly see your point. But that would be like saying to stick with the stock NA motor over a SC'ed one since it would be more controllable with less power.

Again, please look at the video posted and please tell me what I'm missing here. It looks to me like Jason has no problems getting around the track quickly and smoothly. If turbos were so bad they would not be the primary boost option of choice with just about every car manufacturer. When Porsche decides to drop the twin turbos on their GT2 because the power in unpredictable and unsafe then we'll have to rethink this whole conversation.

I find it interesting that those giving their input on why a turbo reacts all crazy on the S2000 don't even own a turbocharged S. I've driven many a SC S2000 and turbo S2000s and can definitely give you an opinion based on facts about both set-ups. Again, I've never talked negatively about any SC'ed S2000, I'm just shedding some light on the turbo.

We both have our places on the market, but to say a good turbo set-up on an S2000 is somehow not suited for the corners is just plain insane.

I think SC owners are just trying to give themselves an excuse for making themselves feel better about their purchase when at the end of the day their car will never make the power a turbocharged car will

Precisely, so when I get on the gas coming out of a corner according to your theory my turbo may spontaneously spool up at 2500 rather than the usual 3500rpm?

Didn't think so...

And since when does a turbo vehicle not make the same power every time at 7000 rpm also? Whether S/C or turbo its dependent on throttle position.

OP: Just go Ptuning for now. Drive your 120 miles of twisties numerous times (even during extreme heat conditions) in one sitting, go to your local small road course/autocross, and then report back any issues (accidents, heat issues, high maintenance, headaches, etc) that you may have.

I win!

What kind of ass hat statement is that! Your ignorance is showing through.

The ptuning kit also has an oil cooler option for those wanting to track their car. There is a nice video of it and it performs well. So enjoy your slow ass SC and watch the ptuning kit rip you a new one on the twisties.

Calm down dude. I am not trying to be an ass. I want to see more customer reports with Ptuning rather than the same people promoting their product over and over. Jesus, some ####ing ppl are so sensitive. Wow, I thought you were a nice guy, but I guess not.

Edit: Also, if you or anyone else want to rip me a new one in the twisties, then hit me up. I live in the SF Bay Area. Backside of Mt Hammy, HWY9, or whatever.

To the OP - the best option for your power goal and boost with this kind of driving is the Kraftwerks kit.

The Rotrex unit was designed by Mercedes for the kind of linear power delivery there large V8's are known for but in the smaller v6 package.

that's only if you have to make X power.

If you want real speed start with tires, suspension, final drive, and tuning and hopefully you also develop your ability to drive faster as well.

or this

And I think your trying to make a sale



either way you go turbo or sc or n/a...if you got the right tires for that specific driving style and setup, it will make more difference then anything else!!!!
