Supercharge or Turbocharge?

Zamir370z · 10-05-2011, 07:23 AM

Guys if you were given a choice, which one would you go for SuperCharge or Turbocharge?

Turbo, purely on personal preference basis.

My understanding is the an SC is better gains over the entire power band and has in the past been favored for larger displacement engines like those on vettes stangs etc. Turbos give better peak power and can give some ridiculous gains. Typically seen on smaller displacement engines. Theres some reason for that but I can't recall I'm sure someone has some better info then me.

There is no clear answer. SC's are often used on larger engines for packaging reasons as well: on a V8, slap low PSI blower on top, and if you are running < 7 psi no intercooling, or A/W in some of todays cars. Parasitic loss is not felt as much to drive the blower.

Turbo being exhaust driven, has less negatives on a smaller engine (the already soft down low is no softer), and you manage power output through proper engineering (A/R sizing for the power band you want, proper intercooling and engine management).

For V engines, you are typically looking at two smaller snails with compressor piping then joining at and A/A IC, then the intake manifold: doable, but far more complicated then a top mount SC typically.

If you were designing a 10 PSI system, either can work well from an output perspective when sized correctly.

Make a poll. I say turbo because you get the bov sound.

Yeah that's my reason for wanting a turbo over a SC, yes childish but I don't care.

Make sure your turbo is a bit bigger than this

wdkwang · 10-05-2011, 10:44 AM

That's nothing, I have ones as biggest volkswagons outside my office. I wish I could take a picture of the turbines we make(against policy), they power oil drilling platforms in the middle of the ocean.

Depends on what you want....SC's for the 370z are just now starting to make the numbers the TT kits have been putting up for several years. For now, the TT's are faster.....but that could change as GTM and others further develope the SC kits beyond stage 2.

bov sound = sex

SC has the BOV sound....GTM STAGE 2

I've modded cars in the past with each. Personally, I thought the supercharger gave the most OEM feeling bump in HP. The turbo was a bit more fun at the peak of course, but required more tuning and wasn't as plug and pray.

For the Z if I were to choose, I think supercharger.

kenchan · 10-05-2011, 02:54 PM

ive owned and played with turbo and sc cars in the past. i like the sound of turbo's better and ease of tuning. not a fan of the whine of superchargers but this is just personal taste.

my2004Z · 10-05-2011, 02:55 PM

Supercharger for me. They seem safer on the engine.

+1

I found myself hating the new shelby gt500 bc of the loud whine it makes. Don't get me wrong, the car itself looks gorgeous.
