    I mean the numbers don't seem bad to me. 473 at 14.5 psi, on pump gas. That's decent, just doesn't look like a solid option for the price. That's the biggest thing

    Three diamonds all the way ;). Its not just the WOT, but a lot of the low load, idle and cruising is on the rich side. Thank you for the confirmation. I'm working on some stuff with my air filter and no cat modded 335xi. Maybe I'll have something useful to contribute soon.

    Apparently they maxed the stock fuel system at 14psi. Also, looks like boost creep to me. And assuming they started the pull at 3500rpm, it takes til 4500rpm to hit 12psi? yuck.

    The knock testing is, in my opinion, the real world best answer testing that's actually fairly easy to do. It directly addresses -via real data- the concerns that people would see if the design were insufficient and backs it up with repeatable logs, remember, we didn't just run it and say it's good, we increased timing and boost until intermittent noise was no longer intermittent. It is a very clear step increase and no one is going to drive their car on the street like that. That said, of course that's not the only testing we did, we also did bench top flow testing and preliminary CFD when we were choosing nozzle locations, analyzing air flow patterns post throttle blade/etc. If you don't like the idea, by all means, don't put it on your car, but just blindly stating that the mixing is not going to happen or the implication that cylinder to cylinder variations are significant enough for the target of this product to be a problem.... unless you did the work there is no way you could know that. Post throttle body injection is not a new concept. In essence, it's flawed compared to proper port/direct injection, but can be optimized in such a way that as a supplemental system it's not only effective, but easy to install, reasonably priced, and very well balanced -IF YOU STAY WITHIN THE CAPABILITIES OF THE DESIGN. If you want to fuel 600 whp+ on 100% E85.... you're on your own there.

    3000gt MR robc1976 Terry@BMS I know you guys just got your kits and Terry was waiting on VM to weld in the venturi but does anyone have any CC readings hopefully showing vacuum after adding in the scavenge? Looking to do this asap once there are results of it working out to be a viable solution.

    Hah, fair on the EJs...I couldn't help myself but poke fun at those motors. I agree there's no need to target that rich - but to your point 1. Loads of people running these motors on 91 pump gas (* shivers at the thought *) 2. Loads of people running these with garden hose meth systems. Lord knows what the actual fuel targets end up looking like. 3. Safety. We could all tune for max power lean, but I'm not going to risk the motor over a few WHP and some spool.

    Bad comparison, that's a shitty EJ motor ;) On my Evo X, with a larger stock frame turbo @ 27-28psi, running 93oct, I still targeted 11.6 - 11.7 up top without issue. The N54 should not need to be ran under 12.0 unless on 91oct.

    Under 12.0 on 93oct is on the rich side for the N54. In fact, sometimes going too rich will cause knock. That said, maybe some are running 91oct, or are targeting a leaner AFR in the flash and meth flow is richening up the mixture. If it is a build pushing a decent amount of power, the extra fuel could be an overly safe measure + the benefit of more cylinder cooling.

    Most PI cars are running well richer than N54s, have you seen how rich the Scoobaru guys have to target to keep things from getting too hot? So i'm not quite sure if I agree with your premise here. Most pump gas tuning seems to target 11.5:1-12.5:1, something in that range. How much leaner would you expect to see it? On straight E85 I think i'm targeting 12.7:1 up top under full load? I'm not sure how comfortable i'd be leaning it out much more than that. Could the motor take it and potentially make more power? Meh, probably...Lean is usually fast until things melt ;) This motor seems to respond to timing advance more than AFR tweaks, at least in my anecdotal experience.

    As I look over all the different datalogs, I notice that the majority of tuners are targeting for for what seems to me as rich fuel ratios. I am no master genius tuner by any means. My perception could be very wrong. With DI, how advance our engines and management is, also with all of the safe guards, I would think any ratio under 12 for pump gas would be on the rich side for our cars. The AFR that seem to be targeted are the same I used on my 25 year old 4g63. Is there something I am missing?

    +1 to everything here, especially the pilot bearing. Just leave it alone, trust me...it'll save you a ton of headaches and it DOES NOT need to be replaced in 99.9% of cases. Changing the rear main seal doesn't hurt while in there, I had mine changed with clutch @ 42k miles just for peace of mind. As for the pivot, just get the brass one regardless.

    Haha...that is a pretty spot on comparison! You can get an AD kit for only $99 more, you'd have to be brain-dead to buy this. Agreed. I'm surprised they are even selling this, it just doesn't mesh with their other offerings. I actually like the design, fit, and finish of their other manifolds.

    uh, not even close. It's not like that's a daily anyway. I have a client who brokers exotics and collectibles. If you can swing 100k or so, an F430 is THE car to buy. Luxury car type maintenance, and they hit a hard floor at about 100, maybe 90 if you find a guy who needs money/getting divorced etc. A clean 360 is 60-80, depending, and a bit more a year, plan on about 2500 a year to maintain. The older 355s are a maintenance NIGHTMARE and they're still 50k+, or 70K+ if they've had some belt retrofit work done. Bottom line as I see it guys, is rather than spending 80k on an M3/4 that'll be worth 15-20k in 10 years you're much better off buying a clean used exotic that's hit a floor. Watch out for the Gallardos until about 06 or so, the E-gear is junk. Also, if any of you had liquid assets most firms (mine included) will do a non-purpose (can't buy securities) line for libor +1.5% so like 1.68% total right now. If you can't swing that I did find a few companies that finance exotics for 10 years with 10% down. A 70k 360 Modena is like $650/month with 7k down. That's pretty cheap considering I'm sure most of us have made lease/loan payments stiffer than that on these cars! Anyway, thanks for the replies, I tried searching "turbo break in" and searching turbo dang anything on this form pulls up almost every post :laughing-rofl:
