They look right to me. Top post is 'Stock from last week' and lower is JB4. Unless he edited later. Damn that's movin w/ the JB4.

93 octane?

So JB4 times are slower than stock from last week?

[le rafiot]

best mode for start road with stock tire = D
start mid for 1-2 and full throttle end the 2

I was gonna say I think 11.6 @ 124 > 11.9 @ 119

Here in Quebec, we are lucky enough to have 94 readily available at the pump at the majority of Petro-Canada stations

Between 5% and 10% as described here.

[CanAutM3]

Thanks for sharing.

Seems car was easier to launch stock (better time to speed and and time to distance in the lower speeds/distances). True ?

Awesome. We get 93 with the same ethanol possibilities. I can also pick up ethanol free 100 down the street by a good ole boy race track. Would probably be a nice mix for a weekend of fun.

THAT terminal velocity with JB4...

The thread last week where someone claimed that the F8x only gained 0,34MPH with the JB4 stage 1 seems quite ridiculous based on the gain you found

[solstice]

124 mph... damn. The original GT-R trapped around 123 mph which should be similar to a 124 mph Vbox. Holy cow.

[Black Gold]

To clarify, is this jb4 stage 1 or full jb4?

Not bad for a RWD car

[JoeFromPA]

If this is a repeatable example, to which I have no specific doubt at this time, wow.

5mph trap speed gain, essentially, from a tune.

And not JUST 5mph, but a jump from 119 to 124mph....to me the M3 is already at supercar territory, but this is truly modern supercar territory in acceleration.

Do you have the DA? What kind of temps?
