uhmmm lets compare that to a better turbo kit.... or add a few psi which the SC can't do once the pully is maxed. OR just do a long/equal length runner so its more efficient, then consider a more efficient turbo. SC has nothing on a Turbo when it come to high end monster power.

SC looses across the board, and looses even bigger past 450whp.

 

The picture is real. All four off the ground. I'll be there again on Monday.

 

When I was looking into FI the KW/Comptech and Vortech all had very similar Torque curves. With good tuning they should all have fairly linear growth. Where as a turbo will often exhibit exponential growth at lower RPM then level off, of course that is complete dependent on the turbo specs. The point is a supercharger will always need rpm and turbo only needs CFM to make boost. So for everyday driving and situations like and autocross you will always have more power available. The only way to get even close to this is t use an Antov transmission on your KW. Some people have tried to bleed boost and use an oversized compressor though the efficiency is very power and usually not worthwhile. So both have advantages but traditionally small displacement engines use turbos to offset the lack of torque. Centrifugal Supercharger are often preferred on big V8's that have more torque on the low-end than the tires can handle to start with.

If I was to buy an SC it would be a KW hands down. I would prefer a screw but I didn't find a kit that was widley used and proven.

 

Yea,

As soon as Asura gets the turbo worked out for road racing (cooling) I think that will be the way to go. A good manifold like the Full Race, and a GT35 would be very nice.

Until then we're putting on a FMIC, a new wheel, and a header to try and crack 450 whp.

WOW thats a good comparison but thats with the fastest spooling turbo out there tho. Do a comparison with a turbo that starts making boost at ..lets say 5k rpm?? in That dyno the s/c will have the more meaty power band until the boost kicks in on the turbo. Lets see that one

 

Also if comparing a turbo to a s/c if you were already going 40mph at 6k rpm you would get instant power/boost from the s/c then having to wait for the turbo to spool up before launching off like a rocket. or brake boosting solves that

 

wait at 6k?.... I think your mistaken sir. Have you been in a S2000 turbo car at 6k.... I can't hardly detect the lag before the wastegate opens because boost is at max about as fast as my foot touches the floor with the gas pedal.


Who runs a turbo that doesn't start making boost till 5k? What is this a 1200whp S2000? I can generate FULL boost by 4k If I roll it on early and this is on a shitty log style manifold, I can't wait to see it on an equal length that's ceramic coated and wrapped.

Lastly the other thing is while you "wait" (not long thats for sure) the turbo still provides some boost it's not like it builds up and SUDDENLY turns on late. Plus on a SC your gonna wait for another 3000 rpm before it hits full bost, the Turbo will hit the equivalent boost to the SC at 6k in about 1 second, especially since the SC won't be at FULL BOOST anyway being that its not at redline.

AHH nvm LOL. I thought it would take a second or 2 for the turbo to spool to reach max boost. i was thinking like as if 2 s2k's were on the freeway going at a certain speed and both going WOT at the sametime, i thought the turbo would take alittle longer to have its kick effect then the s/c? Okay nvm i understand turbo's better now. I was reading on the turbo info http://forums.s2kca.com/showthread.php?t=10106 i made the mistake of saying boost gets made at 5k, i read it wrong lol it makes FULL boost by around that time. but then again i was looking at a gt35 which makes a Sh!Tload more horsepower then a s/c will make.

 

the only turbo car i have been in is my friends EVO. and i was making the assumption that it takes a few seconds for the turbo to spool cuz i watched him floor it and i slowly sunk into my seat in the next 1-2 seconds. But then again thats an EVO....our s2k's are a completly different machine. i'll have to go for a ride in a turbo to find out.

 

If you were thinking old civic and old turbo technology I'd agree...but the new stuff spools faster and faster and the F2xc breathes so damn well.

to someone who can actually go out and read up though!!! Props to you sir Off the line however.... in a full on drag car, there's a reason top fuel doesn't run turbos. We must give the SC credit in some areas.
