    I have been running the RB PCV fix along with the oil restrictor for the turbo and I can happily report for at least 1500 miles no more smoke!

    noorj, so what would be the max safe injection do you think? It obviously has to start after the exhaust valve closes, so around 340* (adjusted for VANOS by a few tables in the DME). What would be a good limit for EOI? In triple injection mode I see the third pulse EOI around 60* BTDCf. Assuming a max Ign Timing in this area where we need max fuel of say 20* (I don't see anyone ever even running this), that would give a max EOI of 21*? How soon before spark should injection be cut?

    I agree, there is no need to make the Motiv manifold twin scroll all the way up t the flange at all. The banks, and pulses are already divided, just not all the way up to turbine blade, it would make a very minimal difference if at atll, and as Jake said would be a ton of work.

    Why? It is not needed. Sorry you can't copy/paste the same VANOS settings that work for a twinscroll tubular manifold. But with fine tuned VANOS tables, the Motiv kit spools much faster than the Cobb OTS settings. Making it twinscroll would have more cons than pros. With the twinscroll v-band housings, the flange opening area is fairly restricted due to the divider, so those would probably not want to be used. Also, the Garrett turbine housings do not bolt on to the Xona CHRA. So switch to TS T4 you say, well that takes out two current benefits of the Motiv kit, ease of install, and 100% completely leak free operation over its lifetime. For true twinscroll you also need 2x waste gates, which would increase cost, and due to packaging and space constraints, perhaps kill the ability for the waste gates to be recirculated. All this for what? Maybe a tiny bit more torque in the 2k - 3.5k range? This information has been known / posted about for almost a year now.

    Yes if the injection window is just 1 intake stroke they would effectively be 700cc/min injectors (if we can hold 200bar). No I would say that almost everyone has not reached the injector limit, just the HPFP limit. I would bet that Tony was at the limit of the injector when he tested with his double barrel setup, but if we could open that window up it would allow for alot more headroom. The equation would effectively be: Theoretical "PFI injector" flow = (injection window/720)*(DI actual injector flow)

    I don't personally care anymore what they do with tunes. Anyone gets to do anything in life and has to start somewhere. My beef with them is LOCKED maps. How are they getting away with that shit when at least for a year or so both BuraQ and Wedge ranted on and on about our maps on Cobb being locked using it as part of their marketing all over the forums posing it as an advatntage before MHD even came out. Funny enough ever since we picked up MHD not a single map has been locked even though we have the means of doing so. Sticky what's this fishy business about what do you think? To add to the list of bs tuning approaches coming from there but also incorporated by BMS in their backend flashes is desensitizing factory knock tables. I think they went back to stock knock tables recently but why touch that on a factory motor?

    Ti is not a a good chioce for downpipes, since is handles heat not as good as stainless steel. This is why even Akrapovic does not fabricate its downpipe out of Ti. Although you could use Inconel or other superalloys.

    Flinchy replied to a thread DI Tuning Discussion in N54
    am i correct in that @ 35g/s, for gas if you could use exactly all of one stroke it'd be roughly 700cc/min of gas flowed, or 1400cc/min if you could use both strokes fully... (easier for me to compare to cc/min since other injectors go by that rating) That would mean the injectors are pretty well maxed out already? but that doesn't really line up with the injection window being less than what should be available going by the tables?

    It was recently brought to my attention that there is a demand for a Plug n Play bucket assembly as well. This was actually the original model for this product but during Beta testing 80% strongly requested to have it as a DIY to avoid the hassles of core charges and to maximize cost savings. So here is what I am going to do, I will add an option to have a Plug n play bucket assembly. Cost will be $349 and includes the lid ring tool, shipping will be what ever USPS calculates for size and weight which I will determine this week to add to the website. Hopefully this will give those who don't feel comfortable giving the DIY a try an option to still save some money and have the same performance as the DIY kit. Would love your thoughts and feedback on this! Thanks, Chris

    Whenever you do work to a system you will add heat. If you remove energy, you remove heat. Hot air moves faster than slow air because the molecules have more energy. Temperature and velocity are intimately combined. What item(s) pull heat, and therefore energy, out of the gas is another story though and no one in the aftermarket is going to model that shit out.
