This website has come a long way. I'm pretty sure the archives are filled with "SC vs TC" threads based off of speculation only. It's cool to see members actually doing things that were foreign to us earlier on. I'm proud to own a 'ho

Maybe they sound like that without an intake. But with one the whine is ten-fold.

im pretty sure power steering is more of a squeal then a whine.

if you wanna get real technical on the turbo vs. supercharger, it all has to do with the engine and its exhaust/intake setup....whether its an inline 4, inline 6, a V6, a V8, V10, V12, etc....a dodge viper will benefit just as much from the supercharger as the turbos, because of the v10 configuration. it would require twin turbos, which may end up giving more power, but are also gonna be WAY more costly than what you could get out of the right supercharger to match up to it. and before you lay claim to the higher horsepower vipers being turbocharged, i believe the fastest recorded time by a street viper was laid down by one that was running a S/C right around 7 secs
turbos also depend on the HP range, your lower HP level turbos may not have much lag, but your 800-above have serious lag, otherwise you wouldnt see most supras, etc racing from a rolling 80mph instead of a stand still....
its a trade off...turbo can be tuned for a little more power but at the expense of not having the power throughout the entire RPM range, or the supercharger, which has a little less power and tunability, but will give you power through most of the entire RPM range

yeah, but there's a catch. With a higher stall speed torque converter, the turbo has a major edge. Mine for example begins spooling at 2,500RPM's and hits peak boost by 3,500 RPM's. This gives me full boost from 3,500 to redline, where a S/C is set up to ramp up all the way to redline (boost level contingent on RPM's). That's a big range on the tach that is not at full boost with an S/C. I'm not a big tech geek on S/C's since I never owned one but this is the way it's been explained to me by many that have.

just for streetablility reasons a turbo is better because sometimes you might not want boost for those lower rpms.

My question is about the S/C pulleys. Why go through the process of changing out the pulleys? Why not just buy the one that creates the most power.............................and be done with it?

^because it will throw off your fuel curves and whatnot...remember the belt is also connected to the cam gears

your right, but regardless if you have a turbo rated for 1300hp, the thing is so damn big that it dont matter how high of a stall converter you got, your still not gonna see boost till higher RPMs, but once you do hit the boost, hold the eff on!

Good question. Remember the more air you pump into the engine the more fuel you have to add also, so you don't just buy the pulley, you also need larger injectors, and maybe other fuel mods to get the right air/fuel ratios under boost. Then there's the fact that the kit you bought didn't come with an intercooler. With a supercharger, the more you boost, the hotter the pressurised air gets. You can only boost so high before the air gets so hot that you actually make less power with more air going in. This is why most kits use a conservative "low boost" pulley for the street, that way you get more power than stock, but it's also reliable and you don't have to go buy all these other parts to go with the kit you just spent 2-3 grand on.

so basically what you're saying is that you have to have one pulley for daily driving, and another track? I guess that's ok. I never go to track anyway.

^umm i think ur confused....u match a pulley to the power your wanting to get out of the setup, because that pulley will also be directly influencing the air/fuel ratio the engine gets because the belt is also turning the camgears (cam shafts) which will require tuning and adjustments to compensate for the pulley size

and once its tuned correctly, you can simply adjust the boost you run to whats feasible for the current application (daily driving would require lowering the boost, racing applications of course you would wanna raise the boost)
