I know this has been beaten to hell, but my friend (that owns a supercharged s2000) tells me the R would lose.


What do you guys think?

Full Mugen Integra Type R
VS.
Supercharged s2000 with:
strut tower brace and springs and tie bars
SC with exhaust

SAME TIRES, SAME DRIVER
thanx guys,

Jordo

Who'd win in a battle? Captain Kirk with Viagra or Captain Picard with Rogaine? Same ship, same crew.

 

ALL ON THE DRIVER I GOT BOTH CAR THEY HOLD IT OWN

2000 CIVIC SI <BLUE>

 

Comptech Supercharged S2000 has no traction. Therefore it's not much of a increase in performance despite the 100 whp at 9000RPM. Go with Speedcraft Turbo if you want to crack 12's.

 

Sounds more like a tire problem then just a traction problem. I have yet to hear of someone complaining about to much HP in a rear wheel drive car or for that matter to much torque.

 

S2000 NEEDS GOOD REAR TIRES TO HOOK UP . I GOT AZENIS ON MY ITR ,ILL TRY AZENIS ON S2000 SOON

 

Not just tire problems there are also other factors. Comptech SC is centrifugal design where it becomes most explosive when VTEC kicks in. As most S2000 owner knows the best time are achieve when launch from 8000 rpm and side stepping clutch. SC S2000 owners usually go for 225/40/18 and 255/35/18 (wrong size but most common made) performance tire and there is still hardly any traction. Most of them have been in the mid 13's where a few was able to get low 13's. Drag radials will help but nowhere as effective as having Speedcraft Turbo.

 

Its hard for me to believe that drag tires of some sort won't let you hook up. Since you are talking about qaurter mile times then this would require drag tires. Lets not forget that qaurter mile times are not everything. A car is a lot more than just how fast it will run in a QM. Since a Centrifugal SC is basically a turbo driven by a belt, it is also hard for me to believe that a turbo would be better. Which it seemes like you only car about QM times or drag racing.

If you are talking from experience than you probably know more, I don't own a S2000. I think you can figure out what I own, so I am basing my opinion from this.
I just have never heard of anyone complaining about to much HP on a rear wheel drive car before. I just don't see how a turbo would help. Where does the turbo kick in.

Nobody should race only 1/4 mile at a time. I am saying all these stuff because the original poster ask question about what SC S2000 will do in real life. In reality SC S2000 are not much better than Stock and certainly don't justify $5,000 price tag. Sev a S2000 owner from Montreal ran a 13.7 on his bone stock S2000. Compare to the average run of SC S2000 of 13.4 the difference is minimal. Limited upgradebility on tire size limits the effectivness of extra power.

Anyways if you compare the dyno plot of both SC set at 6 psi and Turbo at 6.5 psi. The test was done on stock internals. You will find the Turbo clearly have 20-50 hp advantage over SC throughout the whole powerband. The SC was more solely focus when VTEC engage. Whereas Turbo makes most of it's gain down low. The turbo spool up by 3000 rpm but it's not SMOG legal whereas Comptech is.

By any chance do you have Mark Basch SC on your NSX?

 

and Speedcraft makes more power BUT has no traction issues?!? this board is poop

Ryan

 

btw, with all the bells and whistles that are really necessary, the SpeedCraft kit is practically double the price and is not CARB approved

 

Speedcraft Turbo makes more power than SC throughout the entire powerband. Which is a lot more useful power and easier to launch then Comptech. Sorry but going nuts only when VTEC kicks in does not help you get better time.

There is already a guy who broke into 11's on street tires with his Speedcraft.

 

I`m on the s2ki board and I don`t think he`s doing 11`s yet.

Btw, who wants to spend 10g`s and have an s2000 that only goes straight?!? I could build a CRX and do that. Plus, I`d still have a very nice daily driver that I could take to a road course or autoX

Ryan

btw, I have an SC`d S2k and it doesn`t break the tires loose at 6k. Traction is fine.

 

Some people are just really into the turbo's and don't want to give credit to SCers.
There are advantages and disadvantages for both designs.
For someone looking to buy either it would be a good idea to research these things and pick the one that best fits your needs. Not just on the S2000 but on any car. Myself I lean more towards SCers, I don't car about drag racing. I care more about how the entire package works together. The above statements is more along the lines of what I thought.

 

He did that awhile back ago when he was running 8psi.

8K for the kit.

SC S2000 is made to go fast in a straightline as well. Just it isn't very good at accomplishing that's all.

What mods have you done to the car? Have you ran it yet? Do you have timeslip? I would like to see your best time.

 

It's not I don't want to give Credit to Comptech SC. Just the results from all that gain isn't too pleasing.

 

You state Then you also stateSo I think all of us would like to know is, if the the Speedcraft has 20-50 more HP through the entire rpm range then how is it that you can get traction with the Speedcraft and not the Comptech. The Turbo will be makeing power up where the comptech does as well. More HP means more traction? That doesn't make sense, It sounds like the guy with the turbo figured out how to get traction. You are better off just saying your prefer the turbo, because where you are going with this doesn't make any sense.

8k gets you in the door but you know you`ll need more. I`ve owned two turbo`d Hondas and they always snowball.

You sure he did 11`s? Is this ChrisD or the other guy?

I`m SC`d but do not drag race my s2k. I have a CRX that I take to the track and I`m almost finished w/ a 2.0 liter HB that will be an 11 second daily driver. Including the price of the HB, I`ve spent less than 10k.

Ryan

 

It's 20-50 hp throughout the entire powerband.

From 3000RPM - 5000RPM Turbo has close to 50 hp advantage over SC. When high cam engage at 5850 RPM. Turbo still maintains a 20 hp advantage over SC until almost redline.

SC only makes big power in VTEC whereas Turbo isn't.

To achieve optimized time in SC S2000 it is still better to launch in high rpms since most of the power is made there. Turbo's powerband is more linear than SC. You don't need to launch it sky high to achieve optimized time.

 

The kit itself sells for 8K. I think you need more parts though. Comptech's kit includes exhaust, carbon fibre intake and other things isn't it?

Yes I am sure he did 11's when he was running 8 psi.

You should give us some examples to see how SC S2000 fair with upgraded street tire. My friend's modify WRX which is still running on stock Turbocharger totally annilated a modify Comptech SC S2000 at Portland track. The SC S2000 couldn't come close to the Wagon at all.

Here is his WRX friend mods

WRX Wagon
CAI
Uppipe
Downpipe 3"
Exhaust 3 "
No cat
Fuel persure
AVCR
Boost up
All gear tuned
BOV
HKS Coilover
CF race seat
4 point seat belt
STi 4 POT brake
Endless 24 slot disc rotor
Endless CC-X pads
SS brake line

 

This still sounds like a tire traction issue to me I would ask the person running the turbo what tires he is running. You might also ask him how he is maintaining traction.

The WRX isn't this a 4-wheel drive car? I don't think it is fair to compare a car that has far better traction. Apples to Oranges comparison here.

If you are not drag racing I am betting the Comptech would perform great. I am assuming the traction problem would only be a problem in first gear.

More HP means more traction? That doesn't make sense, please explain.

I already said S2000's tire size upgradebility is very limited. Anyways he is using streetable tires and not drag radials.

Considering it's isn't a stock S2000 we are talking about. If you lose you lose there is no reasons to cry about. A fully modify Comptech SC S2000 getting whip on the track by AWD WRX running stock Turbo with BPU.

I already explain to you Turbo's powerband is more linear. Therefore you don't need to launch high in RPM like you would still need with the SC.

 

Woops, didn't read that was at a track(thought it was QM), sounds like the driver needs to learn how to drive.

I won't argue the rest seems pointless.

 

Sorry that I don't explain very well. You'll need to see the dyno plot to understand.

 

A buddy, who is also SC`d, did 12.80 at Palmdale on Toyo`s. Not too shabby for such a poopy track.

Which Guy did 11`s?
