    AWE Tuning S4 3.0TFSI S-Flo Intake Released

    AWE Tuning has released their intake for the new Audi S4. The intake retains the factory heat shielding. Gains are claimed to be 15 horsepower at the crank. AWE was nice enough to include a dyno at the wheels which we appreciate. Gain is 9 whp at all 4 wheels on 93 octane. The intake is priced at $287.95. Specs:

    • Factory airbox is retained for ultimate intake air heat shielding
    • OE Style locking rib at inlet and outlet of silicone hose
    • High flow silicone hose replaces restrictive factory tube (and Helmholtz Resonator on the 3.0T)
    • Significant power gains with no change in sound
    • Peak gains: +10 hp and +6 ft lb at the crank for the 3.0T and +6 hp and +4 ft lb at the crank for the 3.2L
    • Max gains on the 3.0T are +15 hp and +11 ft lb at the crank at 7000 rpm, and Max gains on the 3.2L are 7 hp and 6 ft lb at the crank at 6500 rpm.
    • Washable large cone filter from OEM supplier
    • Flows 34% more than the factory paper filter
    • Available in black or red

    I don't like that torque curve..... you lose 100ft-lbs from 5000-7000rpm.

    Time for a bigger blower?

    It is a steep drop, good point. Bigger blower would be very interesting...

    Yeah, and that's only at stock boost levels. Change the pulley and you will get even more heatsoak/inefficiency up top. The stock exhaust and heads could be bottling it up too though.

    I have never dealt with awe, I have always seen them put up conservative #s which is nice. But heard a few guys on a porsche forum saying they would be ok with their products, but would never ever ever let them touch their car.

    For what reason?

    The reason for the torque drop is because the factory tune opens a bypass valve in the upper rpm's to bleed off boost. I believe the stg1 flashes are just keeping the bypass valve closed.

    LOL why the hell would they do that? Could they not fit a large enough heat exchanger to not knock on crappier gas?

    I think it is because it is a positive displacement blower and you want the bypass to bleed off excess boost.

    Sounds wasteful to me. I'm not real knowledgeable on PD superchargers, but you would think that they would size it and the pulley to feed in a peak boost pressure that stays relatively even throughout the RPM range. Shouldn't the motor consume the extra air in a almost linear rate as it is directly connected to the compressor? Right now it looks as if it was dropping boost up top.

    The Ford Mustang GT500 does a much better job at holding it's torque with the Whipple W140AX (2.3L Twin-Screw).

    It isn't wasteful, it is a safety mechanism. A positive displacement blower is always producing boost. When going off throttle you want a way to bleed off the boost so the air is not forced back through into the blower damaging it.

    That's a giant blower which also is more efficient.

    To me it's funny to see Audi claim their engineering excellence and charge crazy money for what you get when Ford very easily makes a engine with not only much more power (expected), but a much flatter torque curve.

    The GT500 torque curve looks like the S65 torque curve, just minus a few thousand RPM and up a few hundred ft-lbs!

    Well, a lot of people put down GM but their V8's are easier to work on/simpler than their European counterparts getting better mileage and power. I think it is a prestige/perception issue.
