How much would a turbo cost for my ranger?

....3 inch piping on anything is fvcking RETARDED. if a 590 horse GT only needed 2.5"...

*cough* BULLSHIT *cough*

hehe oh excuse me! //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Sorry but no, something with that kind of mass of air flow is going to need a looser exhaust... Sure it can run on less, but that's kinda dumb. 4strokes dont benefit from backpressure.

You put on a 3+" downpipe to lower EGTs, lower post turbine back pressure as well. Might wanna talk to your bro more there buddy. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

forced induction is forced induction? thats the dumbest thing ive read today. what about a supercharger using engine power to produce more power is the same as a turbo spooling up from AIR? where is it anywhere NEAR the same thing.....

Others have said this but im going to make it as illuminatory as possible for you.

Both are forced induction. Both use a mechanical means to compress and blow air into the engine's throttle body.

A supercharger uses a belt driven by the crank of the engine to turn a pair of cylinders with interlocking blades at a high rate of speed to compress air. typically these are known as 'roots' superchargers (Whipple uses this type of supercharger - iirc). Other superchargers use the drive belt to trun a set of gears which in turn, turn a rather agressive looking compressor wheel. (Paxton's superchargers are what comes to mind.)

Obivously there is parasitic drag placed upon the engine via the drive belt.

A turbocharger on the other hand uses the expanding exhuast gasses to spin a turbine. This turbine is connected via a shaft to the compressor wheel which in turn forces and blows air. Since the exhaust from ALL of the cylinders has to pass through the turbine, there is a good bit of back pressure. The A/R on the exhaust housing and the trim and size of the turbine determine how much backpressure as well as playing a role in spool up time.

Again there is a parasitic load placed on the engine with a turbo but in the form of backpressure. In some cases (GM4/5/8 turbos) once above a set psig, the back pressure becomes higher than the intake pressure! At 17psig pressures of 25psig pre turbine aren't uncommon!! (this is stock turbo setup on the old 6.5LTD.)

Just a little FYI.

Btw might want to hang around a few tuning/turbo shops, or make some good friends in the cyclone/typhoon crowd (be forwarned, they are ALL dicks...but in a good way! //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif) Or the GN crowd. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

hehehe yuppers, I love GNs!!

Its the one car that no matter what the condition gives me a stiffy on the spot! LOL //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif Its funny back in the 80s it dominated the streets. Now that theres a new generation of drivers most of em dont have a clue why or how that big, usually black, buick just sucked their doors off like they were standing still.... //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

and if they werent eating vettes they might have had a chance at staying aroungd a little longer.

seeing as the cobalt ss is...well supercharge....so thats a different competition than turbo cars...

the 3 inch piping on all those cars i put money on is not helping. yes u see an increase....but 2.5 would show more. its not about unrestricting air flow completely, its about freeing up the right amount : ) dual exhaust...fully built no supercharge on that GT by the way.

Actually, on a mustang dyno on my WRX W/ a built motor and GT30R turbo, there was a 8awhp loss with a 2.5" VS 3" pipe. Shit, most of the fastest WRX's and STi's run APS 3.5" turbobacks. There are only a handfull of people that make 2.5" systems for a reason. On a NA motor, you need backpressure to make torque, on a turbo system, you have all that you need before the turbo, and pressure after the turbo just lags it down and screws with your effecency.
