Supercharge or Turbocharge?

Jordo!

There's really no reason to think that.

I suppose you could make the case that there are fewer parts that could fail on a SC set up as compared to a twin turbo (for one thing, only one turbine to worry about), but there really is no reason to presume greater safety.

Centrifugal blowers do tend to make power a bit later in the rev range than a properly set up twin turbo (although the torque curve looked pretty flat for this motor on that set-up), but under high load approaching redline, both are capable of destroying a motor in short order if the tune is bad or if the internals cannot tolerate the extra power.

Its not an opinion...its fact. Do the research and understand what I am referring to. Many good books out there. I read Corky Bell's books quite some time ago. Some of the A/R math is a bit deep and not necessarily what everyone needs but you get the idea. I have tuned several aftermarket cars using aftermarket computers, and the fundamentals are really the same: air, fuel, timing.

How the air is compressed is irrelevant. What is crucial is correct engine management when it comes to safety (i.e. making sure the engine does not grenade)

When you say something like 'it seems like the safer route', you are not giving me the impression you have an informed opinion here on the technology and issues at hand. Some of us try to offer some guidance to get a better understanding of the entire system and make a more informed choice for yourself.

Let me give you an example (real world). Assuming equal thermal efficiencies between 0 and 12 PSI, would you rather run a 8 PSI SC system that uses an AFPR, fuel pump and timing retard, or a 6 PSI Turbo system with larger injectors and a fully remapped or aftermarket ECU?

Now remove the words SC and Turbo from the above paragraph and re-read....that is really what is important.

In either case, my preference would be choice B.

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.

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.

Both of you should take a ride in my car it would change your mind.

^He's correct. The GTM SC is very quiet at idle and low rev. The whine at WOT is a sound that any FI fan can appreciate. Both SC and TT are great options, but the SC is probably a better value based on cost and labor as it equates to the power and fun factor you get for each dollar spent.

Jordo!

Honestly, it really doesn't matter all that much, because on this motor you are choosing between a belt driven turbine or two exhaust gas driven turbines, and both set ups are capable of a reasonably broad powerband and considerable top end.

What I want to see is a roots or twinscrew blower for this car. Then there's a real debate to be had...

Either would be a great addition to the car, I went supercharger for the sound and linear power.

Looking at getting a 370 for track use. Which is the more reliable the Stillen SC or the GTM TT? Having ran turbos on the track previously I am concerned with heat biuld up.

Anyone know how much a stock engine can take without internal mods?

GUTCH

I don't know the answer to your question but thought I'd point out that GTM produce SC kits as well.

Reality

You should really search on this subject... If you are planning on tracking your car and worried about heat, forget FI.

For track, I recommend Stillen SC.

For DD and fun, go TT

blackonorange

Single turbo!!!!!!!!!

edub370

^^ that.

i would like to see an sts car get tracked. seems like the remote mount system could possibly help the massive heat increases seen by most FI cars over a prolonged period on the track
