Turbo vs. SC: 0-60 and 0-100 times?

It was 100% a vortec. It was an 01 so it was not an ap2. I know what it was, because I have been friends with the guy for quite some time.
The kit boosted 5.5psi. It is possible the owner of the car went with a less aggressive pully or his psi gauge was incorrect. Either way the s/c 01 didnt make any boost what so ever until 6k.

I got a question maybe off topic maybe not.....Since the turbo is at full boost by 3.5-5k rpms would that account for some of the reasons the turbos are somewhat unreliable? I mean you can drive a SC s2k all day and not go over 1lbs of boost (by staying under 5k rpms) but with a turbo you are always flirting with (or at) full boost pressure which is putting all that pressure on your engine all the time. Does this make sense or am I just reading too much into it?

the reliabilty is more so leaning the parts used. A supercharger is a much more simple and straight forward install. It doesnt require EMS to run.
I am sure the same could be done with a turbo if you are willing to sacrafice power. (ie less than 300whp)
turbos also generate much more heat and require more attention than a s/c would.

It is incorrect to say that a turbo is at full boost at 3500. It is at full boost at 3500 and WOT.
So how much boost you use is entirely dependant on your right foot. it's just that it happens to be there if you want it.

If you're at 3500 cruising and you hit the throttle the SC will act like a normal S and accelerate slowly until about 5000rpm where a bit of boost kicks in and starts increasing torque and horsepower and then hits VTEC and a bit more boost and eventually gets to redline and full boost.
If you're at 3500 cruising and you hit the throttle the turbo will take a very short period to get to full boost and whammo, you're off.
Peak horsepower and torque can be identical but it's the midrange that is different.
But this scenario is not real. I you are in 5th at 3500 and decide to take off in an NA or SC'd car you would drop two gears so your engine is in the sweetspot and hammer it.

One is better than none!

the benefit of a centrifugal kit is that its not a hugely involved install and doesnt require massive tuning. Its an easy go fast solution, which is perfectly acceptable.
