Yeah, it looks like a little storage place now.

One thing that bothers me is the dyno numbers.

263hp on the dyno. 361hp is what it is rated for. That is 27% loss and nearly 100hp. I sure hope the don't know how to work a dyno.

 

maybe a Mustang dyno?

 

Likely, local shop dyno'd theres at 298/322. I'd imagine around a 20% loss that's 372 horsepower, 402 ft-lbs.

FWIW, with an intake and tune only it made 324/341. Good for 405 hp and 426 ft-lbs flywheel.

 

I'm guessing they turned off the torque management.

 

So it's "just a tune" that is going to have the transmission warranty voided and have the transmission very likely dead after a few hundred launches?

 

It will definitely not increase the liftime of the tranny, but regardless of TM on or off; if you beat on a tranny at the track it's lifetime will be drastically cut.

You could kill TM completely and if you didn't beat on it all the time I wouldn't expect any /major/ loss of expected lifetime.

 

I suspect GM did a pretty good job of having TM only kick in where they feel it would reduce the life of the transmission, thus if you aren't driving in a way that would reduce the life of the transmission, then you won't notice any difference with the TM removed anyway.

It's really like me bumping up the boost on my 335i's turbos with a tuner... lots of people like to say that it's safe but the fact is you're definitely increasing your risk unless you drive it like a grandma... and in that case why did you bother with the tune?

 

They also re-calibrated the transmission with the tune, raised the redline cut-off and raised the shift points. I'd say that is where the most gains were made. They stated with the stock tune the transmission wanted to shift early.

Yes the car did go 12-flat, with a shot of nitrous and a drop-in K&N filter. The printed magazine had additional pages where they did the mods.

EDIT:

 

HSV guages. Cost a small fortune and need specific wiring.


US regs say the screen has to be at a certain height for nav. The G8 screen isn't high enough. After market solutions are slowly coming.


Catch up boys! We have guys running 'cam only' in the 10s.....

 

That's right I remember hearing that before now that you mention it. It's a shame though... sure doesn't look much lower than many other nav systems out there.

 

Compare the height of the top of the screen in this picture vs the steering wheel. It is below the center of it. In the pictures you posted, the top of the screen is over the top of the steering wheel. When sitting in the G8, I did notice that the screen looked a bit low.

 

When were these regs. implemented? Here is a pic. of a 2004 Cadillac SLS w/Nav look how low it is. Lower than the G8?
