That 604 wheel is on 100 octane. It's also 281 horsepower to the wheels over the stock 323 wheel. 281 freaking wheel over stock! 93 octane numbers are 492 wheel so about 500 at the wheels on pump gas in an all wheel drive sports coupe. 91 octane falls to 457 wheel which is understandable so California guys may want to look into meth injection. Regardless, nice to know just under another 150 wheel horsepower is there with 100 octane.
What's the price? $12,999.99 and it is only available for 6-speed manual cars which is fine as 6-speed manual cars are all we have in the United States.
Also keep in mind this same motor will go in the upcoming Audi RS3 sedan and already is in the Q3 RS. 600 wheel with those cars is going to be A LOT of fun.
Great work as always APR. Pictures, performance numbers, dynographs, and video below.
