Turbo verses Supercharger

[Blood]

Why not both?

[spc2125]

Well this thread has swayed me towards a SC than turbo

[shaunsweeney]

My best advice is find someone with a turbo car and someone with a sc car. Drive both and see what you like. I've driven both turbo and sc cars and prefer a properly sized turbo for many reasons.

With linear power, you won't feel the power as much as a turbo. turbo lag makes you feel faster. shaving seconds off the track, SC is probably better. street fun, I say turbo. most local guys says the sc is hard to feel the power because its so linear. it reminds them about the power boost hen they drive a n/a 86. DD ability? just stay off boost hen you drive, my car feels fine.

for what its worth, i think the rotrex units arent much like more conventional superchargers and because of that it will have less of the supercharger downsides. from what i gather that fancy oil in the planetary drive system can provide the efficiency of a turbo (maybe even mor efficient) while building boost at a lower point simillar to a centrifugal. then again, its all over my head so...

It's not turbo lag that makes a turbo car feel faster - it's the fact it's making more torque, sooner, than the s/c is the reason it feels faster.

There are more superchargers at the track in California because of CARB, not because they are faster. I'm still curious why people believe turbochargers are impossible to drive around a corner well at the track when all of the best time attack teams/shops are running them here in Japan. The only reason that particular story came up in the first place was because of the old turbo porsches which were indeed an absolute bitch in the corners, but that is also because the engine was hanging out behind the rear axle...

@AVOturboworld do you plan on updating to a rolled flange on the turbo inlet and tbolt clamps in the future? Those are the only things I've been leery about with your kit.

You can keep your mouth shut and be thought a fool or open it and remove all doubt.
You did not choose wisely.

Will the O/P please fix the title?
It sounds like turbos are writing odes to superchargers.
The word is "versus".

The rapid change in torque (caused by the turbo spoolup) and larger overall torque output is what makes the turbo car feel faster.

It's because Time Attack in Japan is quite different from Time Attack in Cali. Our tracks are not as well maintained, and we have a massive street tire class, whereas the Japanese tuners generally are using some sort of r-compound or slick.

I agree that power comes on more suddenly, but you are exaggerating a bit or you've never driven in a well setup turbo car. I am talking more street wise, which is how most people will drive these cars almost 100% of their lives.

Now track wise, turbos can be set up quite well to not be peaky or too sudden. However, superchargers will always inherently have slower/smoother power delivery. But this is somewhat negated on a track where revs are generally in the mid to upper range.

Different drivers will prefer one over the other depending on a lot of variables.

Apart from all the turbo vs s/c pros and cons, what will make me choose s/c at 90% is that I can keep mostly my N/A mods.

I mean, I buy 1000+ header while I'm N/A and then I have to throw it away if I go turbo? Damn that's insane. Probably it's because I don't live in America and I don't really see any real way to sell the used header. Turbo can be fun, ppl love it for the torque it has, passenger love it for the sensation it gives.

It all depends on what kind of power delivery you like. I'm in love with N/A engine and I don't really care about being pushed back in the seat I much prefer a continuous delivery of power with no lag because doesn't matter how good is the turbo, there will be a bit of spool time.

I wish I could just drive both a SC and Turbo car so I could decide as well. At first I was leaning towards SC, but then I got so much crap about how you get more bang for your buck with a Turbo, so Idk.
Personally, 98% of my driving is below 4,000 RPMs. Maybe I'm just too careful with my car, but I rarely push it when on public roads...which is 100% of the time because I've never tracked my car. lol.
If that's the case, SC would be a better option since I believe SC's give better low end torque? Turbos work better when you're reved higher, yes? Or maybe I'm all wrong about that.
Personally I'd prefer to keep most of the stock parts when it comes to the engine. I don't want to add this and that along with a SC or Turbo in order to make it work. I just want to be as simple as possible and install it and get results. Is that not possible? Or if it is, would that be a SC or Turbo?
