    • APR releases high boost pulley for Audi 3.0 TFSI Supercharged V6 (B8 S4, A7) +108 AWHP with tune

      The new 3.0 TFSI supercharged V6 is becoming a popular Audi mod platform as Audi boosted motors often are. APR had an ECU tune available already for some time which was their Stage I upgrade. The pulley is their Stage 2 upgrade and to see the benefit it is best used in conjunction with the ECU tune otherwise the car will dump the excess boost. Gains with the ECU tune are very healthy at just over 100 horsepower at all four wheels, 117 AWHP with 100 octane.

        Lol you got to this before me for once haha. This car is putting down some impressive numbers for a SC 3.0Liter. Wonder how this car with bolt on and tune will do against a 335 with similar mods. should be pretty even?

        This car is putting out over 400 whp on race gas without meth. Pretty damn impressive...

        The B8 S4 has no DCT here, right?

        I'm liking this motor!

        Yes it has a dual clutch option.

        You also left out the B8 S5 Vert in your title.

        Then in that case I put my money on the S4 with DSG.

        Why 335Xi? Not all 335's are Xi's but all S4's are AWD. Bring the best bolt on 335 vs. the best bolt on S4 and rumble.

        because then thats a drivetrain and weight advantage. i mean sure, id like to see both, but then people will call out the AWD ad/disadvantage. from roll or dig.. eh, id like to see either one really.. and something for the S5, the get that thing movin im in one

        The 335 comes in RWD and the S4 doesn't. It is what it is.

        I want to see which is faster, irrelevant that one is AWD and the other isn't. You can't ask a guy in a 335 on the street to go trade his car in for an Xi.

        well i thought we wanted to compare as close as possible. but FINE, if you need to see that a 335 will dominate yet another higher tier car, then sure, find an S4 for it to smoke Click here to enlarge

        I seriously want to see it. AWD is a burden, but DSG is an advantage. Also, think about that despite the DSG it is making over 400 whp. Impressive...

        A FBO 335i should pull a FBO S4 at the same boost level.

        The S4 has a very advance diff that ensures the power goes mostly to the rear wheels. It's an option though.
