    No, I do too. Mine will be setup to race from a dig as well, no worries. I think Terry and Dan are what? 400RPM difference at 20psi? I don't think that's much at all considering the power difference and turbo size difference. I may be wrong on that number, but for guys that race from a dig all these numbers really do matter, and it would be great to see where certain turbos on what kit hit 20psi. I say 20psi cause no matter the turbo, I don't see a 335i launching at anything higher and holding traction. 20psi is probably more than enough to launch with. @Terry@BMS or someone else more qualified may better guesstimate that though.

    If roll events become more popular and prevalent down here I'll probably stop going to the dragstrip, but that depends on how the car likes it. breaking $#@! isn't fun...and neither is buying a lockdown kit, line lock, etc. etc.

    well they do rent out dragstrips for street racing events where you can race any way you want now....that has become pretty popular around here

    lockdown kit etc isn't that bad but when you start breaking $#@! that sucks ass. i would recommend investing in a car trailer if you go that route

    The real difference in my opinion is that in roll racing somebody always jumps. There is no way for it to be fair. Honking is stupid because the guy honking has an advantage.

    i've never been to a roll race event, so I can't comment on them.

    Having a flashlight or an actual track with a tree is so much more accurate and there is never confusion or disagreement about jumping. (for the most part)

    BMW hasn't gone twin scroll by accident. There really is something to it. On our development cars the 5862 TS setup spools better than the 5858 traditional setup and makes more power. The trade off is its more work to develop quality TS manifolds, requires dual wastegates, makes packaging trickier, so it becomes more expensive. For someone doing a 6466 race car I can see why it might not be worth the extra cost/effort. For someone who appreciates power below 4500rpm then it's a must have IMHO.
    even the racecar would likely want TS for the transient response/low speed corners though? Depending on what level of racing i guess.

    and given the N54's need for the separate runners for O2 placement, it's not THAT much more effort/expense to just make it twin scroll the rest of the way?

    lol I think Dan ran 2.5 60' times at the track. I've done at least 1.9 on the VBOX. So between the higher stall and smaller TS turbo it does make a big difference. I'm sure I could get down to 1.8... But I need to be at 1.6.

    2.7 LOL a 1.8 would net me 10s easily at my current power level but that aint happening on my car without a transbrake or an auto with a small shot of nitrous.

    im just gonna go 6mt and enjoy the car lol

    wait wait wait... him? LOL

    i got into a facebook 'discussion' with someone who seemed to think it physically possible to push 600+ easily on stock frames.. to the point they'd 'already' made up a set capable of doing so for 'cheap'

    was absolutely hilarious.

    ouch and lol 600 is possible(max) but its not easy and i have never once said 700whp that is you that misinterpreted wheel horsepower for flywheel.

    and I'm really not going to get into this again with you vargas

They simply are not needed and are inefficient, I do not think you guys understand how much exhaust energy and heat(more energy) is being wasted in these manifolds, while none of the top end benefits they might show are even being realized.
    Twin scroll short runner log style manifold?

    If you ask me for a dig, I'll tell you to grab a shovel. Meh. Not as good. I need to think of something better.

    That said, if you are only willing to run from a stop it's because you would rather have all wheel drive win than horsepower.

    One could make the same argument about racing with a DCT/auto (rather win by pressing the gas than with driving)...
