Well, just got back from a nice day at the 1/4 mile track at beech bend in bowling green kentucky. It was rented out for the day by www.tennesspeed.net. it's an online forum for mainly middle tennessee people with various interests in cars and racing. Had a good turnout of 200 or so people. fastest of the day was a 1200 hp turboed big block foxbody mustang that was just inside the 6's. slowest was 43 seconds an ams evo MR that blew out the clutch and had to baby it to the finish. lol

My best:
reaction-.163
60ft----2.199
1/8mi---9.169
1/8mi---79.7
1/4mi---14.095
1/4mi---101.94

ran 8 times and had 2-14.0's and 6-14.1's. also had 2-100mph runs and 6-101 mph runs.

there was an 07 g35sport 6mt there, i think his best was when we lined up together .
on my slip it says he had a 2.1 60ft....9.1@78 1/8....14.12@99 1/4. not bad. we were discussing his times(high 90's mph and mid 14's times). Its difficult to launch the 6mt without wheel hop and he was doing the best he could. also, he drives the car like a grandma everywhere, so we agreed that the ecm has things running a lil slower due to the driving style. Either way, i and almost everyone else was supprised by the G. It was doing really well.

 

Sounds like you are getting great consistent numbers there. Were people expecting mid-upper 14's? How were the other entry level lux sedans doing?

 

Hey - good times!
So you have an AT? 1/4 mile @ 101.94 is quite impressive... nice job.

 

Great time. From previous posts I saw that you have an AT, did you do this run with paddles, DS, or D? Interesting that he had a slight edge at the 1/8 mile mark, but you pulled away after that, also amazing how close the MT is to the AT in these cars.

 

I'm still looking for the best technique to get the lowest times in an AT. Your times seem very consistent. Can you describe how you drove it?

 

i had went to the 1/8mile a few months ago and tried all the different driving modes. the paddles were the quickest by far.

i would drive around the wet box and stop just in front of it, turn off my vdc, stand on the brake and throttle to bring the revs up as high as possible and release the brake. It would burnout for about 2-3 seconds until i let off and stopped just in time for the staging lights.

there i would line it up and wait on the yellows to start with my left foot on the brake and right preparing to throttle up. as the yellows started, i would bring the rpms up to around 2000. and right as the last yellow lit up i would let off the brake and floor the throttle. (this gave me consistant 2.1 60ft's).

as i went down the track i would hit the paddle in 1st at around 7000 and it would shift at 7500. 2nd hit it at around 7300 and it would shift at 7500 again. 3rd i would hit it right on 7500. and a few times i would try to hold the gear as long as possible but i still had to hit it to forth before the finish.

there is a slight delay on the shifting by a few milliseconds, its enough that if you try to hit the paddle right at 7500 you will hit the soft revlimiter this car has and it slows the shift and delays the power once in the next gear. very bad when in a race or whatever. and yes, these track times confirm what i felt when i test drove the 6mt and the 5at paddles.....they have gotten the auto and manuals almost identical in power/performance.

(except ofcoarse when you get over highway speeds-6mt win that battle due to the power the torque converter eats up as speeds climb)

 

Great info and description of the launch and run. I knew to shift at around 7k in 1st for the shift to happen at 7.5k, but didn't know the gap closed in other gears. Thanks for posting!

 

Have you played around with brake standing at different RPMs? Just wondering, what happens when you brake stand past 2000 RPM? Do you get excessive wheel spin? I would imagine a track is a lot stickier because of all the rubber laid down.

It sounds like the car is ignoring your up shifts and the ECU/trans is reacting to the full throttle instead and shifting close to or at redline. I'm pretty sure the ECU won't let the car bog down if you used the paddle to shift early. I've tried accelerating up to freeway speeds at full throttle and rapidly upshifted the paddle through all gears to see what would happen. Guess what, the trans will still hold up to the redline and ignore the early paddle shifts.

I'm sure you've played around with doing the whole run in DS mode. Your paddle shift points got consistently better times than in DS mode?

Thanks

 

The symptoms you described are not because of the car choosing to hold the gear: At WOT you can still upshift before redline or whenever you want, what the G WON'T do is upshift multiple gears successively. There's a few second delay between upshifts no matter what the throttle position.

 

wow those are great times..im happy to see the 13.9 figure can be backed up. I hope i can run a 13.9-13.8

 

yea its a time delay between the pressing of the paddle and the actual shift. if you try to get any closer to redline in 1st you WILL hit the "soft rev" limiter. thats where it will stop accelerating at 7500 and delay the shift even longer, then when it does, the power is delayed as well. a little feature the engineers like to throw in to keep your *** out of the redline on this car.

yea the paddles are faster. the ds is faster if you hit the revlimiter while on the paddles.....so to eliminate human error and be consistant, the DS is the way to go.


If you launch any higher than 2000 rpm, you WILL get wheel hop/spin on this factory tires. I would love to have some slicks and launch it as high as i can torque it.

 

Nice numbers. What were the temps/humidity conditions?

 

I don't see any difference between DS and D when it comes to WOT shifts. DS wont shift it any quicker at WOT than in any other mode. DS will hold the gears longer before upshifts and such but not shift any faster.
The paddles like DS mode only change or hold the shift points, they dont make shifts any faster. The paddles will give you more control over the shifts so you can shift before redline.. but in this car.. I don't think its much of an advantage.

 

True for the most part. With that said, one must remember that different shift points can alter your timing.

 

These are very good numbers!!!! these are quicker than my 04 S4 6spd!! allthough i did baby it off the line,,, but that car only did mid 14's at mid to upper 90's temp and humidity please......
