my G is out of commision now..so only slips from the M.

R/T 1.114 (iqnore bc it's only test and tune)
60' 2.063
330 5.756
1/8 8.776
MPH 82.37
1000 11.312
1/4 13.457
MPH 103.78
Temp: 68F

need a new thermostat, car is losing hp, my trap is way too low.

 

Very nice. I was just comparing the numbers (with a grain of salt) to that of the 2007 G35x someone brought to the track (in the sedan section). Same 60' time. 1/8 mile - G35x was just under 8.9 seconds at 78 compared to your 8.7 at 82. But the M must have long legs because while the G35x finished at 13.9, the M is a 1/2 second faster and 4 mph faster.

 

here's a slip from drag times.

my time is not where I want it to be...it should be at 13.2 @ 107mph

my trap of 103 is lower than my highest trap I had last summer of 105, I lost some hp due to a faulty thermostat...I will need to get it changed out then run again at the track.

Basically the M has more aggressive gears and 'maybe' weight slight less.

Also at 330hp it's higher than the G, though with a significantly lower torque.

 

it looks like u squeezed that 13.4 from a good 60 time. I agree u should trap atleast 105mph with that kind of 60ft time.

 

I don't care if that's a low trap or not; I'd love to trap >103mph

Good times regardless

 

thx. I think Im pretty good at the launch now...But these tires (PS2s) are not as grippy as the Re-01Rs I was running last summer.

 

107 trap is very optimistic.

Under the right conditions, it should be anywhere around 105.

Not saying 107 stock is impossible, its just that you need a great run in a great track.

Good times by the way.

I do realize that 13.2 is by a pro driver..probably powershifting(though not likely because R&T are against such practice) But I've achieved 13.37 last summer with much heavier tires (2lbs per wheel) and a 60' not as good as this season. With the right conditions (my service engine soon light not on and a new thermostat.) Im hoping to at least match my last summer stats and get at least 105 trap.

 

here's why I love R&T

 

I wish car magazines would start showing 60' and 1/8th mile times and speeds. It gives a good picture of where the car's strengths are as opposed to just the 1/4 mile time and speed. FOr instance, this M ran a 13.2, but was the time that low because the driver ticked off a 1.8 sec 60' time? Or was it a 2.3 sec 60' time, but the car had brutal acceleration afterwards? Some of that you can tell from the trap speed but more info the better.

 

I agree re launching with the PS2s.
Otherwise a great all around tire.
I also found them to be very sensitive to pressure changes.

...great post BTW;
especially since mine won't find it's way to the strip.

I had a blast with it at Mosport though

 

why not? Isn't there a good strip up there.

 

Sure...
I just prefer a track to the strip

 

yeah..the track is far from here...I'll do that later.

PS. does your car make a clicking sound around 3K rpm

 

Yup... It's the Double Vanos system
