Why not Supercharger instead of Turbo?

[jasestu]

Erm, just a thought, what would be need to be done with respect to keeping the ECU happy when adding a supercharger?

Basically the same as adding a turbo.

AGAIN!!??

ignor all these technical mumbo...go back to the basics and you'll know which system is efficient...and in terms of motor-engine engineering, efficiency=power
turbo uses wasted exhaust gas and converts it into power
supercharger uses a pulley (which uses part of the power that the engine produce to turn) to create power..
its almost like saying which recycle bin would you use...the one that recycles 'trash' and make a nice sheet of paper out of it or use the one that takes a nice sheet of paper and recycles the nice sheet of paper into another nice sheet of paper?
we should lock this thread before someone gets hurt....or before george comes in....

Hehe.. it got beaten to death last time, I think George will pass it up this time.

Actually there isn't much to discuss!! Turbo rocks and beats the hell out of superchargers anytime............. There is NOTHING as wild as a 1.6 bar SR20DET engine :finger:

1) This is incorrect. With the exception of the centrifugal supercharger (which basically uses a turbocharger turbine) the supercharges are much more inefficent in compressing the air. And will create a hotter charge at comparable boost levels.
2) I don't think that is correct either.
3) Sounds like you got this backwards too.
4) That's where a good wastegate comes into play.

Most of those points sound backwards. I'd like to hear your rationale behind 2 and 3.

hey people don't pick my nose! :silly2:

J, tell you the truth, my die-hearting friend who has a passion for supercharger gave me those info. Actually, my two roommates who are not convinced that turbo is the way to go in my car. I am here just to prove to them that they know "jack" all. The above message threw them somewhat off the chair!

LOL. OK guess you'll just have to step up to the plate and 'prove' them wrong.

Dead wrong on both accounts.

DEAD WRONG

Read the SE-R Mailing List archive. Read the archives for this forum. Read Mike Kojima's Suck, Squish, Bang, Blow article - just for starters.

Wearing ladies dresses would be different too. You're not going to do that are you?

What the fuck do you think a supercharger does?

Dude, I don't mean to flame, but you really need to learn more on this subject before making more embarassing statements.

There's a lot of misinformation out there, but if you read Mike Kojima's and Rob Cadle's writings on the subject, you can end up knowing more than some folks who make a living selling these things. They can get technical, but both are pretty good at keeping things simple most of the time too.

Actually, when talking about SC and turbo efficiency, what the real discussion is about is compressing the air while inducing the least amount of heat.

IOW, at the same air flow rate (whether SC or turbo), the more efficient compressor will pump out lower temp air.

But, Luke's point about turbos not consuming power is not a small point either. It just doesn't figure into the efficiency question.

Too late.

Wrong.

No sense letting such severe misinformation get repeated without the true story at least being told.

So now you know......

Don't listen to them.

They don't happen to be eating bananas do they? :right:
