Supercharger... anyone have times yet?
I've searched through most of the various s/c threads and have seen the dyno #s, but so far I don't think anyone's taken it to the track or even guesstimated the 0-60 or 1/4 mile times based on user experiences in everyday driving. How much of an improvement do you guys actually notice? From what I gathered it seems you only really can use the power between 4000-6200rpm. Is that enough to justify the investment? I know there are going to be aftermarket pulleys, intercoolers, etc... How will those affect the overall powerband of the s/c? I personally would like a little more power down before the 4k mark. If anyone gets track times, post em up cause I'm really interested in seeing how much of a real world difference the s/c makes.
Nothing official, just a few runs using a Beltronics Vector accelerometer. My best was 0-60 in 6.5, and 1/4 mile in 14.85 at 94 mph. I'm gonna try it again in the next few days. I'm hopin 4 low to mid 14s in the 1/4.
BEL stuff works just like G-Tech acceleromoeters. I'll try to find a spot to do couple of runs with my G-Tech, see what I can come up with. Can't guarantee a 1/4 run, but will definitely do couple of 0-60 runs.

I always thought accelorometers were very accurate, specially if you have more than one (gtech pro competition has 3). I always thought the difference was that they take the mph at the very end of the 1/4, while at a track it is a average of the last part of the track. And also there is people error such as not finding a level place to test on (slight incline would be lower times, slight decline would be faster times).
Yes the g-tech is very accurate if the user sets them up correctly. If you know your vehicles weight to within say 100 pounds then they are pretty darn good. I only have experiance with the older black g-tech pro but I found it to be within 5hp of every dyno I ran and within .25 of a second on the qt mile. Who knows mabey I just got lucky but I used to be at firebird every sco night about two years ago and used to check the results next to the g-tech! I think they are a pretty cool baseline type toy. The main factor is goofy results on a device like that is the user most of the time.

You won't get get close to a 13....the SRT-4 puts out 230 whp and is equipped with an LSD and the best drivers can get a high 13 out of that....I'd say mid to possibly low 14s
We installed the TRD s/c on a customer's car this week, and my one word review of its performance would be "effortless." Vast improvement over stock, but in very subtle ways. Can't wait to get hold of an available 5 speed and do everything -- springs, shocks, rims etc. That's going to be fun.
Anyway, don't know the 1/4 but unofficially 0-60 mph came in at 6.5 and that's a conservative estimate, meaning if you're really good on the clutch or have a quickshifter, you might do considerably better.
Now if we can just the whole thing worked out with the automatic.

On average -
Its a tenth off or less in the 1/4 and less than 1 mph off in the 1/4
The G-Tech Competition, SS and RR have 3 meters in them and not just 1 like the first gen G-tech did and even then the 1g G-techs were about 2-3mph higher in trap speed and maybe 1.5 tenths in ET, but its still BALLPARK.
Its just a TOOL for tuning its not law, jesus or anything of that sort.
Tracks measure ET at the first timing light and mph after you cross the line and enter the second set of timing lights.
Car & Driver recently tested all the units on the market and compared them to the on board timing equipment they use and the G-Tech Pro SS/RR (or old Competition) was the best out of the bunch and the BellTronic's wasn't far behind either.
Also given the increase in power and torque the typical TRD SC install is getting mid to low 14's are about as acurate as your going to get. It would ET better if you launch it at an higher RPM to launch closer to your torque peak. But you need slicks or drag radials to do that.
Keep trying Ryno....
My buddy ran down the 1/4 with the G-tech still in his 13 second SOHC Neon -
time slip - 13.5(4)@104.5
G-Tech Pro - 13.5(5)@105.1
If you want the read out from his G-tech and the Time slip posted to prove these things are as accurate as your going to get for $300, let me know.
