I finally took my 2009 300C AWD to the track last week and I'm not too enthused with the results.. my last run was the best but I know I can do better.

I'm just wondering though.. what does R/T mean and what are all the numbers, 60, 330, 1000?

Here's my printout:

R/T: 1.203
60: 2.234
330: 6.344
1/8: 9.629
MPH: 76.02
1000: 12.476
1/4: 14.873
MPH: 96.02

The track was a bit damp, and it was cold outside, maybe 18 degrees C. It was at night.

I've got Michelin Primacy MXV4 AS Tires, Fast Nemesis Satin Black 18 inch rims, BCR BR Type Suspension (Lowered about 1.5 - 2 inches), K&N 57 Intake, Borla Extreme Catback Exhaust, Diablosport Intune 91 Octane CAI tune with Firm Shift Points & MDS Disabled. The car is also vinyl wrapped in a matte black, so that might add a bit of weight.
R/T is reaction time. You were sleeping at the light. But it was fun though, huh?!? . As soon as the 3rd yelllow lights up, that is when you go. Don't sit and stare at the greeen light. Aim for a .000 to a .2 to be respectable.

Those other numbers are your time in seconds to those marks. 60ft, 330ft, 1000ft, etc.

The 60ft is your tell - how good or hard you launched. A 2.2 sucks unless that is all your torque converter and tune allows. Expect a 2.0 and strive for 1.9s if the car allows it. AWD makes it consistant as long as you maximize all the available power the tune/ecu and torque converter allow.

Sit at the countdown with a foot on the brake, and one on the accelerator. Load up your torque converter as high as it allows for the hardest launch with AWD. If you are not hearing the tires squeal, fill them to max psi for less rolling resistance and to try to get your rpms up as quickly as possible with some slippage once rolling.

R/T is your reaction time - looks like 1 second lost there.

Tires might be a factor, as well.

All in all - not bad for an AWD noobie! Hope you had fun. :)
Sigh. R/T has nothing to do with the ET. The ET clock doesn't start until he breaks the beam at the start. I highly doubt he was sitting and spinning all 4 tires, nor so stickly they bogged him down so tires were not a factor whatsoever.

Good info but might want to let him know that the brake and accelerator only works as a quick flash or slightly longer stall up... Longer than a second or two and our cars will pull timing and you'll fall flat on your face after launch... Your 60's will be killed because of it...

Sounds like fun! Work on the 60 ft time and you can improve your ET.

As noted above you cannot load these cars up much or the computer will pull throttle AND timing! Really hurts the 60 foot time.

Life begins under that 2.00 mark, each tenth at the short side gets a couple on the big end...

That is very true, he should practice to find out. AWD and the torque converter may be different than the RWD cars.

Took my 2013 300c AWD to National Trail Sunday for test and tune. Best ET was 14.427 @a little over 98 mph.
Not bad. Sounds like fun! What was your 60 ft. time? Were there any other interesting cars there? I've still got winter tires on my Cobra. I'll probably put the summer tires back on before the end of April and will be ready for some more track days soon too.

26 Degrees Celsius, Dry Track

R/T 0.396
60 2.106
330 5.935
1/8 9.061 @ 78.45 mph
1000 11.775
1/4 14.043 @ 100.08 mph

Still A/S tires though... I had the chance to get Summer ones and I blew it coz it was very on the spot and I didn't have time to think... I'm running Michelin MX4V's in front and Michelin Premier A/S in rear lol coz the MX4V's are discontinued and I had to replace a rear tire & you gotta get 2 for balance...

Nice times pal... How was the d/a?

I bet you have a good 2 to 3 tenths in it yet. Hell with rubber and a converter you'd really be rolling out!

72 degrees F
348 ft elevation
70% humidity
28.89 inches HG


one of the guys reckons I'd gain a tenth if I stop using fat sidewalls (I use a 275/45 R20 on the back instead of a 40 profile).
My AFR sensor is still all to pot (I reckon I've set up the ground on the sensor lead > pigtail incorrectly), so Johan had to leave the tune alone - the output only varies between 8.5 (the base reading I set) and 8.57 (upper reading was set to 18.5), (its an inline sensor with no gauge, it goes straight to the Trinity).....I'm still running the 'get you going' basic tune! I'll get round to redoing it next week & get back to logging.

I'm getting very twitchy about the rear axles, so I only dropped the tyre pressure to 32 psi
