ehh...less efficient..

It doesn't necessarily flow less air, the super charger just draws power off the crankshaft through the accessory belt.

so basically t/c is better than s/c?

Quicktime_GT · December 24th, 2007, 01:44 PM

good write up...

I'd trade my procharger set up for a nice turbo set up any day.. That whistle at idle coming from a centri charger sounds wicked though... or the whine of a KB.. wow...

Both have pros and cons, but IMHO the T/C is the better unit over for make power and keeping your car very drivable.

A KB Set up though will Give You a much better curve through Your power.
Where as a Turbo Will Come on Screaming after 3500 rpm's...
Much like a Centri although there's less of a trade off for power

A TC will still boost MUCH faster then a Centrifugal though, and will produce more power and MUCH more torque at the same psi.

i really want to turbo my stang 97 mostly stock bbk cold air intake bbk headers and flowmaster cat backs my ? is does the engine need any low end work to run 6-8 psi and does the tranny need any work to run it if so what would it be and around how much would the work cost and thats all fro today thanks turbo nice write up btw

Ho_Edge · March 11th, 2008, 11:24 AM

two quick questions...i remember there being two little downsides (not really downsides just things to deal with) i think the term for one was "backwash" and the other had something to do with letting it cool down before you turn off the engine....or maybe it was that its bad for it to just start it up for a couple mins, like to run a minute down the road or somethin

any chance u could clarify these?

backwash turned out to be more of a myth then anything

but you gotta let the car come down to idle before shutting it off

you cant rev it up and shut it off real fast

I know so many import guys with turbos that love to turn the key off with thier foot on the gas...

I have a friend with an 03 or 04 turbo galant. Not 100% sure on the year, but he blew a t25 turbo.. Guy loved to rev his engine and cut it off with his foot on the accelerator..

Why? Is he a retard?

The power curve is not "better" with a twin screw, the instant torque is what makes a twin screw worth while, esp for drag car. If the curve was better it wouldnt get smoked in the upper rpms. Also somebody mentioned turbos are better for daily driving... what? Turbos are not easy to drive and hard to run constantly with, a centri or twin screw is going to be your best daily driver

zolen · March 31st, 2008, 04:06 AM

most roots and screw blowers should be good for 100000-200000 miles before needing to be rebuilt.

zolen · March 31st, 2008, 04:11 AM

definitely roots or twin screw for a daily driver. Need proof? watch a video of a turbo stang on youtube that shows the tach while accelerating. It is ridiculous. the one I saw had bad lag between about 2-4k rpm (about like being nat. aspirated) then the boost just came on like crazy at about 5000 rpm and caused serious wheelspin. Believe me, I have an 03 Cobra, and I woudnt trade my low end torque and progressive power for that peaky crap anyday. Yes the turbo will make more power with the same boost, but I know that I accelerate the most between 2 and 5000 rpm. that is where the roots and screw blowers literally blow the turbos away.

TURBO= coked up engine parts and extreme under hood temps.. not for me, but then we each have our own reasons

ALECSM · June 13th, 2008, 03:47 AM

itschristorres8 · June 30th, 2008, 03:03 AM

generally a 5psi turbo will match the power a 9psi s/c makes usually AT BEST 8psi off a s/c after bolt ons...
