turbo's all the way. superchargers are cool to have the power right then and there. but in the long run more potential on a turbo. all you have to do is build the motor up and adjust the fuel delivery system and up the boost. more power right there. supercharger you have to build the motor and bigger supercharger and it has a limited potential. about up to 15psi. or so. a turbo i've seen them up to 44PSI on a car and about 30-35 on a turbo diesal. they use wasted exhaust gases instead of off the crank. and the wastegate feature is great for higher altitudes. helps control the boost to get the most out of it. it increases and decrases the boost to keep it at stable levels.

get a sequential turbo which is a smaller turbo for low-end power and a bigger turbo for high end power. more piping to run. and more valves to control direction of exhaust gases.

they have centifugal (spelling??) turbo's which is a turbo set up but instead of a turbine that uses the exhaust gases there is no turbine but a shaft with a pulley on it connected to the main belts. which is connected to the crankshaft. it has it's ups and downs.

but i prefer the standard turbo set up. i like the sound and the kick it gives when the turbo's kick on. i like the lag only if it's a small lag. cause when you slam on the gas car barely moves then a second later it takes off and throws you in your seat. especially on a high boost big compressor turbo. i like the feel a turbo gives.

so in the end i think turbo's are better. what i think.

 

i think turbos are better as well but superchargers on a v6 or v8 are pretty decent too, ona 4 cylinder i would always choose turbo

 

Yeah Whipples!!!

 

Can you put a twin tubro on a 4 banger as long as you put the turbos on the same side like they do on skylines and supras with the straight six? Just to stay on subject I like the sound of a turbo, but don't know much about them. I've only had my ss s/c for 2 weeks so I don't know much about s/c either.

 

i don't imagine there being enough exhaust to power two turbo's with only 2.0L of displacement.

 

I ment not just the 2.0L but any 4 banger.

 

Short answer. NO.

 

twin turbos ona 4 is for show purpose only it wouldnt help you go faster and even ona supra they switch out the twins for a single anyway since 1 is better than 2 for 1/4 mile times

 

i've seen a single turbo supra push out 1000+ yes a 1000+ HP. and a twin turbo supra run about 700+HP not too bad. and i saw a tri turbo supra run about 800+HP it's in the 800's just don't remember the exact numbers. and the tri turbo isn't even 2 cylinders per turbo. it's like 1 and a half.
on any good set up you want to have at least two cylinders per turbo. i've seen a quad turbo but on a V12. thats 3 cylinders per turbo. which is good and decent. but 4 cylinders per turbo is where it kicks ass. seen a twin turbo V8 mustang push about 935hp can't remember if thats at the wheels or not.

they switch to a single turbo because cheaper easier less piping less weight and generate same horsepower. plus it's nicer to run one turbo at full boost then two turbo's. the single turbo supra has about an 18g turbo and threshold is a little higher since it's so big. but when it kicks in the boost climps the gauge so quickly. and it generates so much power it's insane. you slam on the gas you don't go anywhere then about a second or so later you get slammed into your seat and you stay slammed into your seat until the boost keeps climing to peak boost. and it'll last a lil while. which is why i love turbo's.

 

turbos rock

 

SC's can make alot more than 15psi but efficiency starts to degrade. and that instant torque makes driving around town fun as hell. vortech rates their sc's max psi at the point where eff is at 60% but they can go further. turbos have that lag problem but not the parasitic loss, my powerstroke likes to wait about half a tick before it kicks when i stomp on it. and theres also that heat. im still divided on what im doing to my 351. id love a big 14-71 blower hangin out there.

Gravana was supposed to be working on a turbo kit that bolts onto the ss/sc for some twincharger action. havent heard anything else about it. and VW is supposed to be coming out with a twincharged 1.4l motor making 175hp soon.
