    Why? What is the stock redline?

    All data thus far shows large benefits on the N54 and N55 heads. They are hardly BMW's best cylinder head work.

    I have no doubt there are good gains as an individual component, but the engine works as a system. With the tiny N55 turbo I have a feeling the gains are not going to justify the cost. Just a guess though and I would love to be proven wrong! Now if you go with a big single or N54 with upgraded turbos it will make a bigger difference.

    If you're moving more air it will always make a bigger difference % wise. Everything I have seen leads me to the conclusion that there is room to gain in the N54/N55 head.

    But this is on a Vargas upgraded turbo which obviously pushes much more air then the stock unit and also when people start throwing on bigger singles. Its a great option to have and gains have showed on dzennos car with n54+rb turbos. So no doubt it will show gains on n55 + vargas turbo

    Thanks, I will have to look that up. That is exactly what I was asking for was data from other cars.

    Actually higher CFM with the same diameter tubing with the same boost is a higher velocity air. A higher CFM with the same piping/boost is always more velocity and if AFRs are dialed in it usually means more power.

    2 things wrong with that, you aren't getting more CFM with the same size piping, it must be increased to increase the CFM. Secondly, as I stated, if you are increasing the CFM of the part that is not the choke point, then the gains will be less than expected. Ie, the head flows 60 lb/min and the turbo can flow 45 lb/min, then increasing the flow of the head even more will have minimal gains. When you then upgrade the turbo to a large unit, the head would be the restriction and gains much larger.

    Around 6800rpm. The DCT has pretty short gearing so shifting around 6000rpm maximizes time under peak power.

    In the USA, only with the E92 335is with the N54.

    In the rest of the world, N55 with DCT was mostly available in post LCI E9x.

    Especially the N55 as intake valves are 1mm larger in diameter and head cooling is so much better than the N54. Better crankcase oil vapor control and crankcase pressure wave control also. S55 Block is basically a closed deck N55 block.

    Yep - love the 335is, but it isn't practical for me. They offer an E90 M3 with DCT, but no DCT in the 335i E90... Boo. N

    ot going to lie, after seeing C&D's test today on the new S3, it is starting to call my name. DSG, 4-doors, but still relatively small, 0-60 in 4.4s, 12.9s quarter and typical Audi interiors? What's not to like?

    Just had to be in other markets outside the USA for the DCT in the E90 with N55.

    I hope terminal oversteer with Audi's FWD architecture is also calling your name.

    Then there is the maintenance costs on Audis.

    i think you meant understeer, and yes, they can push, but it sounds like they have incredible grip now up to that point. I need to drive one.

    We need to get you a high quality scanner.

    Regardless, that's pretty impressive performance.

    The RS3 will be a rocket.

    I've got a pretty good scanner - it is just a pain in the ass to use compared to the iPhone.

    And yes, the RS3 should be very quick. I just hope they actually bring it over here.

    Yes I did. Don't know what happened. Audis are OK up to 7/10th. After that, they become infuriating then scary for me.

    With the front outside wheel loaded and the rear inside wheel lifting, I would be concerned at those speeds. The weight transfer rear to front is overwhelming on any front engine car under braking, but it seems to be worst on the front engined Audis.

    That's probably a good way of looking at it. The non-RS models certainly aren't track monsters.
