The G-spot

[GoCougs]

What's it called?  My runs were done with a full tank of gas, so that's probably the difference maker.

Speedometer.

A full tank of gas in the G37 is ~120 lbs. What with my bike, hitch rack and gear, and 1/8 of a tank, I'm about the same as-tested weight. Even removing 100 lbs probably won't even get you 0.1, let alone 0.2 to 0.4 sec. Could be the accuracy of the app. Could be the road wasn't level. Could be atmo conditions. Could be your higher mileage.

Well, you are at essentially sea level and I'm up in the mountains so that could be part of it too.

I might have to download the app and see how fast my car is.

Took off the bike rack, took the tool bag out of the trunk, and now its in the low 60s. I managed a number of 0-60 in 5.1 and 5.2. It's hard to nail the 5.1. When you brake torque the G the converter immediately flashes to 2,300 rpm and then falls to 2,100. The trick is to launch at the peak flash RPM. If 3rd gear were 15-20% shorter like it should be and if the converter would stall higher or if it had launch control, I think my G might hit sub 5.0 times.

Good to be back in my car. Yeah, the driving position is definitely lower, and the steering rack has a tighter ratio than on the sedan. Makes it easier to maneuver around tight corners. I don't know if the steering differences are coupe vs. sedan or RWD vs AWD, but i'm betting it's the latter.

[SVT666]

I wish my steering rack was a touch quicker.

I used the same app as Cougs and this morning I made one run with it and knocked off a 5.33 second 0-60 time.  Full tank of gas, 1600 ft. elevation and I outweigh Cougs by about 100 lbs.

[SVT666]

Just ran a 5.24 second 0-60 time.

Speedometer by who?  Tim O's Studios?

[GoCougs]

How are you getting readings to the hundredths? At least for the iPhone app it only reads to tenths.

Speedometer xPro by Hodel Apps.

[Laconian]

Different accelerometer sensors with different apps == apples to oranges.

[SVT666]

Speedometer xPro doesn't exist for Android.  I'm using Speedometer by Ulysse.  It has a race function on it.  Very cool.

You should go to a drag strip.

[GoCougs]

The world is my (existential) drag strip.

Just ran a 5.24 second 0-60 time.

wut is dis app u speek of.....

nvm i see toasts.  i mean, posts.  i'll hafta find one for iDevice

New mileage high for me: 25.2 mpg driving down to Disneyland.  Mostly highway driving, 70-80 mph.  Not bad.

[Laconian]

It must be a zero sum game, because I'm getting my all time low mileage for this tank: 15.9.

Did we switch to winter gas already?

[MX793]

I don't think they switch to winter fuel until sometime in October.

[12,000 RPM]

So glad to live by a lake. I get that pure uncut no ethanol shit. I have been getting ~21-22 in mixed driving with that. I switched to regular gas for this tank, 18 mpg with slightly more city driving. Only thing is, I think economically it's a wash- pure 93 is about $0.50 more than the ethanol shit.

One good thing though is I think we are out of A/C weather. That should help a bit. When I jumped in the car today I was actually cold!

Hey! This is the G-Spot, not the Z-Spot. Start a Z thread where you and JYoder can talk about your cars!

[Laconian]

Hmm, Google+ autoanimated some random pictures.

I'd need a substitute JYoder...

New tire time!  My old ones were looking a bit bald, and the rainy season is about to start here in the Bay Area, so I figured it was as good a time as any. 

The previous tires were Bridgestone Potenza RE760 Sports, which I was pretty happy with.  This time I went with Bridgestone Potenza S-04 Pole Positions, which seem to be a higher end tire and were about the same price.  Car and Driver rated them 2nd to the Michelin Pilot Super Sports, which were almost $200 more for the set.  I was out the door for $670, with a $70 rebate to come in the mail -- not bad at all.

Maybe I'll take the G out to the mountains this weekend and give them a workout...

[GoCougs]

I just put on my Blizzak LM-60 snow tires. All my rattles are pretty much gone. The factory Dunlops wore very quick and that was obviously the problem.

My alignment was WAY out owing to all pothole-filled logging roads I drive, which has given me +1 mpg boost.

[GoCougs]

Hmmm. Have any fellow G owners had issues whereby the 7AT does a super hard shift periodically at light throttle in the lower gears? I've had it happen a few times and surfing various G boards it's sorta common. I've got ~10,000 miles left on my warranty, so if she goes I hope she goes quick as 7AT replacement can't be cheap esp. on the AWD models.

[Laconian]

Yes, but only when the engine's cold. It's usually preceded by an odd +500rpm flare in RPMs w/o any surge in acceleration.

Whirrrrrrr-*hard shift*

It happens about once a week.

[Eye of the Tiger]

Since it is obvious nobody here knows how transmissions work, let me just inform you that they are showing classic signs of about to catch fire and explode into a thousand pieces while you are driving down the road.

[Laconian]

FYA. I'll take my transmission apart and replace random parts with wooden shims and dry spaghetti.
