    Alright, Im an advocate for both... For highway and Desert Running. I would DEF go turbo. Your RPMs are already up, dont have to worry about turbo lag.

    If we where talking cars, I would prefer a turbo car over a SC car any day. The feeling is unbeatable of a turbo! I had a dodge SRT4 running 27lbs... SOOOOO fun. Way faster then my SC 06 mustang. Way faster then about any car around actually!

    If I where to artificialy aspirate (sp?) my truck, it would def be with a SC. I want the power down low for towing and crawling.

    Just my 2 cents, its all about application.

    This one is for Chris, So the air in the Turbo gets warmer like you said, Does the BOV really make enough difference in cooling down the air to be worth it? Or do most people simply use it becuase of the sound? Becuase I LOVED the sound of My BOV! But I just wonder does it cool the air down enough to be around the same temp as the SC?

    Not really a fair comparison, as Im SURE the mustange was no where near 27 lbs of boost. And...like I mentioned before, if turbos are the be all and end all of speed, why arent the top fulers running them on their cars??

    You are dead on 100%. Let me rephrase. To be able to SC the Mustang to run with the SRT4 I would have had to rebuild the motor to be stronger, I guarantee I could have built that SC'd to be way faster then the SRT 4 but HP per dollar with these 2 paticular applications, the Turbo won hands down. Ive I had the money to build myself a fast car, I would be torn between super charging and turboing... you can build both and make awesome vehicles, look at the Viper Hennesy TT1000. 0-60 in like 2.7 seconds. But yes, SCd cars can do the same just as easy.

    The blow off valve has nothing to do with cooling of the air. A Blow off valve is in place to ruduce compressor surge or stall when the throttle is lifted to shift, or whatever, under boosted conditions. If the blow off valve is not in place, and the throttle is lifted from an under boost condition, thus closeing the throttle valve (butterfly), it creates a high pressure "surge" in the intake, traveling back into the turbo compressor, causeing a compressor stall. All the "Cool" POV sounds you hear, more than likely, are tuned to sound that way and serve no purpose other than to make the sound.

    Ok. This being said, I belive the discussion was regarding the Tacoma. The Tacoma being predomantly a truck engine, AND, the superchargers are redilly availibly in many kit forms, thus makeing it the more logical choice for boost. if going for max h.p. and with a well grown and blossomed money tree, either turbo or supercharger will produce whatever gains are desired in these engines. XrunnIT said it well, Turbo is good for power on top. Superchargers are good for power all thru the rev range. To get a turbo to "act" like a supercharger and deliver the power from the low revs to the high, it would require lots of engineering , and trips to the money tree, for a Tacoma aplication.

    Exactly, Hence why I said I would supercharge MY Tacoma rather then Turbo Charge. Although I think I will just leave mine naturally aspirated.

    Thanks for bringing to light the function of a BOV, I was under a completly wrong impression of its function.

    PS. Where are the seeds for this "Money Tree"? Im in the market for one of those OR a Sugar Momma.. Either way...

    The sad thing is the SC for the tacomas loose their efficiency above... 9psi or so...

    So do Turbos. Any compressor looses eficiency the higher the pressure.

    While that is somewhat accurate...

    For the TRD blower (Eaton MP90) on the 1GR - 10psi, 14k rpms > 90% efficiency. 5psi, 14k rpms - 95% efficiency.

    You can always go bigger with the turbo. Not so much with the make/model specific SC.

    Going bigger wont increase efficiency. Look at what Xrunnit posted. No turbo is that efficient.

    The thing is, that I dont see SC pushing the same amount of boost and creating the same HP numbers as turbos do. If you want big power, go turbo, wont smooth, easy to use powerband go SC.

    Thing is, Turbos are cheap, and easy to come by. Now your starting to find SC's being used more frequently as they offer a broader power range than a turbo and they are comming down in price. 10 psi boost out of a super charger is still 10 psi boost out of a turbo. SO, pound for pound, they will make similar power, just the SC will give it to ya off idle, where as the turbo has to spin up a bit.
