Hi all this is my 1st post and here is the story of my C32:

My car beat 4 Lexus GS 400 on street so far which are rated doing 0-60mph in 5.8s as spec. So as my assumption my car must do better than 5.8s. I have never brought mime to the track so really don’t know how it performs. I bought a G-Tech competition and upgrade the firmware to RR 4.01 version (the current up to date) . So far the best run I ran on street (not on track) was 6.9s where the street is not perfect flat (you can easily notice the road uneven and chipped) and start at about 2000rpm (at this rpm, my rear wheels start spinning). With this 6.9s, it’s impossible to win a 5.8s GS400. I guess that the GS400 must do slower than 5.8s on street (since it’s impossible to archive the perfect condition of the spec) and I could do better than 6.9s on track but don’t know how much better? So does anyone know how accurate 0-60mph time between street and track? If it’s 6.9s on an average street then how much better if it’s on a track?

Please do not give me the spec 0-60mph. I just want to know the real number.

Quickest "official" stock 0-60 time I've seen was 4.9 sec, but I find that a little hard to believe. You should be able to run about 5.2-5.4 sec all day long though according to others with the GTech.

Thanks SilverBulletAMG! So far my best was 6.9s on that road which is really really slow from what you've said (5.2-5.4). I think I will work on it

Do you know the setup of G-Tech and how the others launch? I am affraid of doing it wrong.

Thanks again

Well at the drag strip I did 0-82 in 8.6 secs. 0-60 should be around 5 flat!

wawy

I agree with SilverBulletAMG - in the real world you should be between 5.2 to 5.4..... You will get better with practice!

C32meC32

I really don't want to compare to track at all. I just want to know the average number on road. I know every road is different. That is why I say average.

Thanks!

DO A SEARCH I THINK THEY HAVE A STICKY ON IT.......YOUR GTECH MUST BE OFF. I HEARD WORSE CASE SCENERIO IN STOCK FORM IS LIKE 5.3. MAYBE YOU HAD TO MUCH WHEEL SPIN OR SOMETHING BUT MY OLD IS300 DID BETTER THAN 6.9 AND THE C32 FEELS MUCH FASTER........I HAD A IS350 AND THE SPECS FOR THAT WERE 5.3 AND THE C32 FEELS A LITTLE FASTER STILL.

C32meC32

Is there a chance that something is wrong with my G-Tech? But I read on the G-Tech website and some other places online, they say that it's hardly to have a fail device and most of times, it fails because wrong setup.

cscollis

Why would you not want the track numbers? They are alot more accruate than a GTech.

BTW: I launch the same on the street as at the track with very similar results. Bring RPM's to 1300-1400 with the footbrake and let off and roll into the throttle. Works every time! I get 1.9 to 2.0 60' at the track which is pretty good for such a small street tire.

I guess drag racing my vette made me better at launch my C32. Not the same experience. Vette 1.6X > C32 1.9X and the vette runs mid to low 11's.

C32meC32

It's not because I don't like the track number. It's because I haven't had a chance to go on track. Plus I bought a G-Tech so I just want to know how well I am doing on road.
Another reason, we are driving on road everyday not on track

TJ_Andrews

Only difference between track and road is the tire spin, and I notice tire spin is greater at the track usually unless you're on slicks. It's pretty much the same number if you launch right.

My C32 did 5.4 in 0-60 but in 55 degree weather, this was in Moroso the night
before Thanksgiving where I met up with (4) E55's, (1) C55 and (1) C230 chasis
with a V6 engine in it.

When my car was stock, I got the following numbers with G-Tech Pro RR:

Road Times:
========
Best 0-60 time = 4.91 seconds
Average 0-60 time = 5.13 seconds
Best 1/4 mile time = 13.8 seconds
Average 1/4 mile time = 14.05 seconds

Track Times (also had G-Tech with me to confirm track results):
==================================
Best 0-60 time = 4.81 seconds
Average 0-60 time = 4.96 seconds
Best 1/4 mile time = 13.68 seconds (G-Tech recorded 13.61)
Average 1/4 mile time = 13.8 seconds

Of course after Stage 2, things DRAMATICALLY changed...

Best 0-60 time = 4.225 seconds...
Average 0-60 time = 4.45 seconds...
Best 1/4 mile time = 12.71 (on the road and before SL55 airboxes)
Average 1/4 mile time = 12.85 seconds

Keep in mind these numbers were recorded on fairly even roads and brand new Pilot Sports 2 tires with 19" SL65 rims (very heavy), which helps in initial traction because they are heavier, but takes a little away from top-end.

Hope this helps...

So far, I have improved a bit. Last night best run on the same street was 6.4s 0-60mph. It's already dropped 0.5s since 6.9s couple days ago. However, working on 1 second to match with most of you here (5.4s) is almost impossible for me.
I have 18"x8.5" aftermarket chrome wheels on it. It might be the reason why it was slow a little bit. But can these wheels slow you down a second?

Still working on it. I believe I can bring it down to 6.0s but I don't think I can bring it down to 5.4s on my G-Tech. I am afraid something is wrong with my G-Tech or I have a wrong setup.
Can you provide your G-Tech setup please?
Thanks!

I have the Escort G-Timer in my car.

I drive a 04 CLK 500, the fastest i've recorded in my car was a 5.28 sec 0-60

I'm sure that this was accurate, the previous day i was at the track to tune in the G-timer.

However i did the 5.2 0-60 when it was 34 degrees outside. when it's like 80 it'll pull around 5.7

Is it possible you're having IC pump issues?
I was wondering as look at these posted times and compare your C32 to the C320 time:
2002 Mercedes-Benz C32 AMG 5.1 13.6
1994 Mercedes-Benz C220 8.7 16.9
1996 Mercedes-Benz C220 9.0 16.9
1999 Mercedes-Benz C230 Komp. 7.6 15.7
2001 Mercedes-Benz C240 8.8 16.7
1994 Mercedes-Benz C280 7.8 16.1
1994 Mercedes-Benz C280 (auto) 8.4 16.5
1995 Mercedes-Benz C280 7.9 16.0
1996 Mercedes-Benz C280 Sport 7.3 15.8
2001 Mercedes-Benz C320 Sport 7.5 15.8
2002 Mercedes-Benz C320 6.8 15.1

I am leaning graphs now and find out that I have best launch at 1800rpm on my car so far. So I am working on it looking for the best. I am very much sure I can do better than what I have now so far, but there’s still a chance that there is something wrong with my G-Tech. I think I will find another one to see what’s going on.

Regarding the C320 time, I don’t think C320 can compare to mine since I am already down to 6.4s and the time on C320 is 6.8s as you stated.

Just like I stated from the original post that I had beat so many GS400 rated 5.8s, let say the average GS400 will do something like 6.00s, I beat them quite easy so I have to do better than 6.00s but I am still at 6.4s???

Anyway, what is the IC pump? I’ll double check it.

Thanks

SilverBulletAMG

You either have a problem with your car or the GTech. One of the two...
You don't have traction control on do you? That would kill your time also.

I ran a 4.6 0-60 with the Beltronics accelerometer, not sure how accurate these things are. Heres a video for anyone whos interested http://www.youtube.com/watch?v=avd2SUSrHz4 The best I ran was a 4.4 but I dont think that is possible, the car is stock, the temperature was 34 degrees, Im not sure how much difference that makes.

C32meC32

Thanks!
I saw this clip before . It’s very impressive. Thanks again.
However, I think the Beltronics is not so accurate. From running the clip in slow mode, your instrument shows you started launch at 2rd second and reached 60 at 8th. So I my calculation is approximately 6s for your run

Sorry if my theory is worng! Please do not get me wrong. It's a very impressive run really!

Thanks!

C32meC32

Thanks
I blame on my G-Tech ). Cause' again I beat GS400 rated 5.8s, I must do better than 5.8s.
I don't have traction control on btw.

Thanks

It's the Intercooler Pump, it's what cools the air that the supercharger is forcing into the engine, the C32 has a common fault where this pump fails (quite often gradually) and the net effect is that the engine management unit shuts off the supercharger so in effect we're driving a C32/C32ish/C320.
The reason I suggest it is that the pump failure can be quite gradual/progressive and the only real way to tell if you have the issue is to plug in diagnostics in so that you can read the SC cooling temperatures.
Another symptom is that the car performs better when cold but that's quite often the case especially if you live in a warm place.

C32meC32

I bring it down to 6.1s 0-60mph today 70 degrees outside
I believe I can bring it down to 5.8 now Working on it

C32meC32

It's down to 5.985s 0-60mph this morning 60 degree, full gas tank.
Working on 5.8s on my G-Tech

What do you mean launch at 1800-2000 rpm? I hope you are not reving the engine at 2k rpm in Newtral (N) and then drop it in gear!!!
