This is a common misconception: https://www.s2ki.com/forums/index.ph...f=142&t=431495.

 

By and large, turbo setups take about a year to of constant work to get the kinks out. If it's not a boost control problem it's bolts loosening or a manifold cracking...

I don't think many people would recommend turbo'ing your car if it's a daily driver or track driven. HOWEVER, for ultimate speed there is simply no other way to go on this platform. The difference in the way our motor reacts to turbocharging vs. supercharging really is amazing...

That's not to say there aren't fast supercharged cars. Sideways found a good amount of HP running a smaller pulley (I think it makes about 14psi) and getting his head professionally built. But, power definitely comes more easily from a turbo setup.

 

Turbo is just as reliable as SC is you choose your parts correctly, install and tune it properly. Cheap parts and half assed install will no doubt put a dent in your reliability giving the misconception that turbos are not reliable..

Its a moot argument as to which is better really cos at the end of the day it depends on the individual what their preferences are and what they want to achieve. If all out power is what you want putting everything aside then turbo is the way to go. If you know that more is never enough like most turbo owners here, then turbo will be your best option

 

I'll number your comments so I can respond to some of them.

1. This actually hasn't been proven. Everyone just assumes that a turbo is "unreliable" but I think only ONE person has ever regurally tracked his car with a turbo. Granted, he apparently had issues BUT I've 1. never seen the thread 2. no one has any idea what parts he was using, power levels, etc, so its basically a bunch of BS until I've seen that.

2.This is all subjective. I personally think the turbo exhaust / engine noise sounds so much better then a SC but thats just me. Also the turbo blow off sounds 10 times nicer and louder but, again, thats me.

3. You can easily hear the SC rattling,clanking, whistling when stopped...not to subtle to me? Also some people will put the black grill peices on so you can hardly notice the IC (just looks like a radiator).

4.Have you seen a dyno graph of a GT35R turbo on a s2k? My horsepower is almost 100% linear and my torque stays nearly as flat as a plateau. If ANYTHING, a turbo makes the powerband of a s2k perfect...

5. A supercharged car is a GOOD BIT louder then a turbocharged car is at idle AND driving / wot. Why do you think SRT-4s can get away with no mufflers yet still pass noise regulations? (hint, turbo acts as a muffler).

6. Probably so

7. Another common misconsception, turbo lag doesn't exist in this car especially if you get a GT30 turbo. You just have to get used to the gobs more power that the turbo will put out for cornering; that doesn't make it worse, it makes it faster thus better. You'll need to get some thicker rubber though

8. Right, the turbo would beat it even more . In a full racetrack where you have nice long straightaways, sweeping corners, and regular corners the SC will die, no question about that. MAYBE in the autox, the SC will win because your taking little corners back and forth 4 feet apart and at 30mph so traction becomes a problem with downlow torque. Given equal drivers and equal grip, the turbo would kill it however.

9. Maybe

10. I disagree. If you install the turbo correctly, get the proper RELIABLE parts, and get a good tune, there is no reason why your car can't be reliable as well as a DD + weekend track car.


People need to get these unreliable misconsceptions out of there heads. Because one kit was fairly unreliable does NOT mean all kits are

 

^AMEN !

 

5. SC is much louder in than turbo when it come to exhaust noise. At Idle Vortech sound like its going to break down. I am more afraid of getting a ticket with my exhaust now then i was turbo charged.

 

Spec,

So you wouldn't hesitate to do 10 hot laps around a circuit? You are telling me you don't have any issues with heat? This is not what I've been reading. In fact, there's another thread where a guy wants to drive his car from CO. to TX (I think) while turbo'd. Plently of owners advised him against it due to the heat the car will develop on such a long trip.

How can this be headed off? From what I have read this simply appears to be the nature of the beast. Again, MSM is the only guy I have read about that has built a circuit-driver turbo car. Again, if there was a turbo kit that was truly bolt on, no tinkering, no heat-related issues, etc...I think it would be a no brainer and this argument would no exist. It simply doesn't exist from what I've seen.

 

1. Got some stats to back that up? A good turbo kit, properly installed and tuned will be just as reliable.

2. Exhaust sounds are completely subjective. Sound alone cannot be used as a positive or negative for either type of FI.

3. I have yet to meet anyone who thinkgs my intercooler is retarded. Then again, its all subjective so this point cannot be used as a positive or negative.

4. A SC does NOT keep the stock powerband. What dyno plots are you looking at? The closest I've seen that maintains a relatively stock powerband is the SOT/BRP kit. That isn't even officially released yet.

5. A turbo car will most likely be SIGNIFICANTLY quieter at IDLE. I'm willing to bet that my car is quieter than almost all centrigual supercharged S2000s across the entire engine range.

6. How so? No crank pully for my turbo kit. Turbo manifolds aren't exactly rocket science. I'd say they are about even.

7. A proper turbo setup will dominate a supercharged setup everywhere. Period.

8. It's pretty common knowledge that power isn't the best solution for an autocross beast. A road track would be a different story.

9. Biased towards the better of the two forms of forced induction, perhaps. More efficient, more power capabilities, better mid-range torque, etc.

10. Cost spent on turbo kit: $8,000
Cost spent on S/C kit: $6,000
Not having to downshift in the turbo car to destroy the S/C car: priceless

11. Really? Thats what I do and well I'll be damned if it isnt running perfectly.


Without data to back your claims, your statements have zero credibility.

Hmm...Well said. Spec, can you please list your setup for those of us whom would be interested in building a fast, reliable track car...done right.
