I'm not sure there is clear advantages to one over the other.

Superchargers are belt driven and you don't have spool up lag. Most people I've talked to tend to think you can get more power out of turbo though.

For my money I think SC is probably less stress on the motor as boost builds throughout the rpm range, where turbo's usually kick in at a certain rpm. For most NA cars its easier to SC, where turbo's take more tuning to get right.

I'm sure if you do a search someone will tell you what the deal is. There are some bright people on here who know their stuff, a hell of a lot better than I do.

 

Centrifugal SC like Comptech and vortech still have some lag, However Roots type SC like Jackson Racing use has lot of torque at midrange.

Thanks for the replies on Super vs. Turbo. Did some research on the two, and one difference is that super steals some power from the engine (based on being belt driven) where turbo does take power from the engine. Part of the issue (as I understand it) is that turbo takes a bit of time to spin up, but this has been rectified by using ceramic parts that spin up quicker.

Any additional information is appreciated.

BTW, I own an 04 S2K with 5600+ miles since Oct '04.

Thanks.

 

yes turbos spool off the exhaust gasses, then have a seperate wheel (that the intkae goes into) and compresses that air, then ususally through piping and an intercooler then to the throttle body. boost is reugalted with a wastegate (using a spring then bleeds of excess boost into the exhaust) and pressure it still releived by a b.o.v.

you could have better low end than these superchargers with a smaller ball bearing turbo, the bigger the turbo ususally the more lag (time until hitting boost)
a nice small turbo like a gt28rs "disco potato" could be fully spooled under 4000 no problem then pull hard to redline with the right tuning.

another benifit to a turbocharger is you would need to be at WOT (wide open throtte, or fully steped on the gas) for it to be spooled making boost, so mpg would be the same as stock until you floor it, while a supercharger (this is what i assume, my car isnt supercharged) would always be in some sort of boost unless you your under 1300 rpms lol.


so those are just some differences betwwen the two.

also, want to intorduce my self i matt as you can see by my screen name lol, i currently drive a 240sx that i just finished swaping a engine into (is having lots of problems) and really want a s2000, its just such a solid car.

yep

also this is a BUMP for this thread, it is aewsome. i didnt nknow if i had the patience to read 15 pages about the 2 supercharges but it was good and leaves me still wanting more!!!

 

1.Where is THE place to get a Vortech kit these days?
2. Anyone has 4.57 gears with the blower? Cause I have a NA s2000 with 4.57 gears and all the NA mods u can buy for your money and I beat a SC s2000 from 0-100kmh..after that, well thats a different story

 

Well I was having fun reading this and learning but I must disagree with your opinion that a 75 shot will only deliver 75 HP at the crank. A 75 shot will more likely go between 65-80 RWHP. Case in point my 2000 C5 was 375/425 RW HP/TQ Cam and bolt ons and 490/640 RW HP/TQ with a 100 shot of NX N2O. Maybe I was just lucky?

Just to add to this thread, it seems like jegs is selling the vortec kit with powercooler for $3999, which is a hell of a price.

WRONG

The Vortech supercharger kits have a blowoff valve so it does not boost at partial throttle.

 

Could have fooled me! Mine has a lot more torque at partial throttle settings.

 

Maybe it is time for this thread to head to the FI forum.
