Ahh..Even though, talons/eclipse 4 cyl. manage ~190 HP with 91. ?
It would seem, with an extra cyl. and extra displacement, you could burn 
more fuel and air without knocking, therefor have more torque and HP.

Thats what I said - normally 130, seemed like 100. 100 < 130

Once again, I think that that the talon runs 12 psi (~.8 bar ( I suppose 
on an AUDI it would read 1.8 bar ) ) with normal 91 gas.. I don't know if 
it matters ( probably not, as it is a turbo car, same amount of air 
(mass) with the same amount of pressure as a lower altitude ), but I am 
about 6000 feet above sea level. I believe that is the reason that they 
don't sell >91 octane - I was in New York/Eastern thereabouts and saw 
everything from 86 (wouldn't put it in my lawn mower) to 94 (!).

I have a few magazines that feature readers cars with some sort of 
supercharger or turbocharger and a NOS kit. I think it will work fine as 
long as your fuel pump and injectors can handle it.
