Turbo vs Supercharger
they are both great...
I'm flipping the coin between turbo or supercharger at the moment...
not an easy choice...
it is leaning towards a supercharger at the moment....
i believe i can set up a supercharger for cheaper than a good turbo...
I dont want extreme boost levels...
All i can say is, whenever people are trying to achieve extreme powers,
they seem to use turbos... But than again if you look at drag cars, they use superchargers... Maybe its also something to do with straight and V engines... I think indy cars are a v8 and they use turbos....
Stuff it.... They are both great, it just comes down to budget...

personaly i am doing up a gem not a skyline
so i like the super charger my self.
not that i think they are better just not as common.

As has been said already, superchargers are just generally less efficient. Also your fuel economy may well eat s*#t because on a turbo you can whack down the boost and it may even be MORE economic than NA. Superchargers will always be less fuel economic.
I spent a long time debating this but came to the conclusion that a smallish turbo (T28) would be better than supercharging. Plus if you're going to spend the money on forced induction you may as well do the one with (arguably) more potenial and efficiency, which will probably pay off the purchase price difference in fuel anyway.

lol I was told the only way to change boost was to change the cogs

Which is still true.archangel62 wrote:lol I was told the only way to change boost was to change the cogs
Im yet to see one work outside of a factory engine setup.Crumz wrote:Don't you know you can get clutch operated chargers that allow you to turn the boost on and off via a switch located where ever you want??

As everyone has already stated, it all depends on what you want from the car.
there are 3 main types of supercharger, (roots, centrifugal, and screw type blowers.) Now over the years ive heard many opinions on which is the best charger to use, and it only needs a quick glance at the performance aftermarket to see which is the the most popular. The centrifugal charger is probably the most widly used these days, with companies like Vortech, Paxton or ATI making various models to suit many different engine characteristics, But when it all comes down to it, Its basically a cranck driver turbo. The compressor has very simmilar mapping to that of a simmilar sized turbo's compressor, The only real difference being that the supercharger inflicts Parasitic loss onto the engine, whereas the turbo uses waste gas from the engine to function.
The main reason that people are using superchargers however, is strictly for the low to mid torque figures, and the low overall setup price. In my books, those pissweak toyota superchargers dont deserve a look in. They are Archaic pieces of junk at the best of times. For a supercharger i would personally be lookin at one of the bigger centrifugal charger manufacturers and see what the have on offer. or if you have the dollars, invest in an Opcon Autorotor screw type charger, you will never look back.
for the best allround performance, look no further than a turbo system. When correctly setup, a good turbo system can deliver boost at the rpm you want and carry an even power and torque curve, pretty much to redline. look towards the JGTC (japanese GT championship) and you will see that the race leaders are always in well developed turbo cars, and the guys that have all the issues mid race with bad fuel efficiency and major heatsoak, are the guys running the supercharger setup. infact the only race applications that seems to pit superchargers in front turbo's, is offshore marine racing where having a shitload of power and torque down low is essential, or burnout comps.
The only real inherint problem for the turbo setup, is that it will cost more that a supercharger to setup, due to the amount of associated hardware needed to make the system work. But at the end of the day, a well setup turbo system can and will be your best friend.

im on GeminiCoupe/nicks side with what he says and with tx240 too
there is f*#k all heat transfer to worry about with a turbo as the air dosent spend enff time within the turbocharger to obsorbe the heat and the surface area is small,the heat is from the compression of the air and the efficiency of the turbo
if anything a supercharger would be more likely to introduce the possibility of detonation as the torque curve comes on alot lower and stronger than a turbocharged system, but what like what was said befor fuel values and ignition timing will stop this from happening

Cheers Nick (GeminiCoupe) and good call TX240. I've heard similar bad things about that Toyota blower, and the reference to JGTC was a good one.
Turbos just have better base efficiency which makes everything easier, and personally, high rpm is the most important place for power.

Rotor = rebuilds, s*#t sound, less torque, no fuel efficiency, can't rebore, etc.
High RPM relative to what the engine's capable of. Clearly in a thread about forced induction I'm not talking about ways to increase maximum RPM...
