peter,
You guys do an amazing job. I saw APSed 350z on a dyno couple of days ago - very impressive. A lot of jaws dropped when it dialed 435whp and near 400wtq on a stock motor. Once the kit gets CARB EO there will be no more excuses for me and many other Californians not to get one.
Sometimes my wife drives the sedan and 400+whp in her hands would make me very concerned. How feasable would it be to have low/high boost setup with APS?
Something like 8-9Psi tune on 91 octane (for him) and 4-5Psi tune on 89 octane (for her), also this way I'm not worried if she mixes up grades when fueling. What additional equipment and how much more tuning would be necessary to acheive that goal? Ballpark figure is all I'm asking for.
Thank you,
Andrew.

Yeah I would feel much more comfortable having a larger frontal opening, you can never get enough cool fresh air when producing high power from a turbocharged car, the more cool air flow the better imho.

I will post a power graph tomorrow, I'm off for a test drive now.

Imagine having 4 sets of engine tuning maps (each tuning map precisely controlling air fuel ratio, ignition timing and boost pressure) and each tuning map perfectly tuned for a given fuel octane, 91, 93, 100 octane as an example, and the 4th tuning map for 100 octane fuel and NOS combined, this is the direction that APS is heading towards at the flick of a 4 way switch, all good fun I'm sure you'll agree.
Thanks
Peter

Very possible and this is a product concept in development right now, maybe available later this year if all goes to plan.
Good point and I believe that we at APS will be able to go one step further in the near future.

As promised, the dyno graph has been placed on the APS G35 TT web page at http://www.airpowersystems.com.au/350z/g35/g35.htm
It's the 3rd graph down.
What a hoot!
