    No clue on the AT stuff, but are the torque paths and interventions in the DME rom enabled or disabled? Not sure it applies at all, just thinking whatever you're changing could potentially not even be active.

    Orb replied to a thread BMS Replacement PCV in N54
    All valves have a leak rate so how much are saying it leaks. The most important roll of this valve is going to be how it preforms at -0.5 PSI (vacuum differential) were it will spending most of life at. I will do a leak down test a calculate the total loss of air per minute for the valve in both modes (pressure and vacuum)

    Nice! I knew the f87 had a pretty good chassis because the shorter wheel base does allow it to rotate alot easier eliminating the understeer and snap on oversteer I felt in the m4. It just makes the m2 feel so much more balanced. I was contemplating buying an m2 csl in the future (have a deposit on it, and I'm supposed to be first at my dealer). But I'm having second thoughts, even if I get a csl it's going to require me to still strip it down and swap almost all of the parts. Like the seats most likely will need to go in favor of recaro profi spgs, I'll need a full cage so the half cage is useless, the suspension will probably be swapped for jrz rs pro suspension (I hope they make triple adjustables), I'll need to swap the wheels for a wider set and lighter set, brakes will go in favour of AP racing set, and probably alot more carbon body panels. In terms of engine yes the s55 is alot more advanced but I believe around 550whp to 600whp with proper tire sizes and a wide body to kit support those sizes it reaches the limit of power you can go before it's just a total skid fest and the power becomes unusabale on the track. So a speedtech stage 3 on the n55 is good enough to compete with the s55. Only difference is the s55 has alot more efficient air to water intercooler which can be offset on the n55 with water Injection.

    Just realized LightWeight did a S55 swap. Guess it is proof of what the upcoming M2 Competition could be capable off.

    Here is a good representation of what the M2 platform is capable of. LightWeight Performance M2 CSR lap around the Sachsenring. Very impressive time. Test performed by AutoBild magazine. LightWeight M2 CSR - 1:29.73 For comparison: M4 GTS - 1:33.17 M4 CS - 1:34.01 M2 - 1:37.65 McLaren 720S - 1:29.46 Ferrari 488 GTB - 1:30.99 911 Turbo S - 1:31.23

    thats why i take what i read here with a grain of salt. i know some of the same people as you and i have friends with 900 hp turbo'd coyotes and a guy i work withs brother is a pit member for a top fuel team. if you know engines and know your stuff the n54 isn't rocket science. i dont claim to know much, so i always consult with someone who i feel does. good luck and i hope we can cross paths next summer.

    Ok I stand corrected, still don't know much about the ring lol. Horsepower will help the car out on larger tracks, handling should be fine.

    And you accomplish what? You don't move the powerband to the left as the turbo still has to wait on exhaust gas to spool whether it is 3 psi or 30 psi. I'm not understanding how you can't wrap your head around the fact a turbo will never be spun mechanically by a direct physical connection to the motor. Exactly. A supercharger is not waiting on exhaust gasses. No matter what you do you will not change that. In other words, it can't match how it builds boost due to the physical impossibility to begin with. Secondly, you can tune a specific turbo to try to mimic a centri and then what? You have a very narrow operating window. Tell me, what happens on say an LT1 when I use any of these centrifugals? Boost is built in the same manner whether it is the C1 or F1X. Output will vary greatly but you will still have linear torque delivery in the exact same manner every single time. How are you going to match that with various turbos? I have a spread from 150-1500 hp there that all builds boost the same way. You are not going to get turbos of that hp capability to all have the same style torque curve or linear delivery BECAUSE IT IS PHYSICALLY IMPOSSIBLE. The reason you always see centrifugal blowers come out first is because they are the easiest to tune for. Boost always comes in the same way. The centrifugal compressor will have boost proportional to the square of its impeller speed. Turbochargers will not. Frankly, any decent tuner knows this and why centri's are the easiest to tune for. And there is your flaw. Within the capability of the compressor. A centrifugal compressor in a supercharger setup always has the capability of boost proportional to the square of its impeller speed.

    Add about 25 - 30 sec to BTG times, to get an estimate of full Nurburgring lap. From BTG website... It takes a top-end sportscar less than 25 seconds to cover this distance. Most normal cars with a 120mph top speed over 30 seconds.

    The tables that most obviously should change it don't in practice. Next stem will be to just mod the universal scalar on the DME side. I'm moving on back to trying to stop automatic upshifts in M mode.

    The F80 M3 and F82 M4 platform is in the 10's on pump gas and street tires. It was only a matter of time really and just waiting for winter and the strips on the East Coast to open. MIR (Maryland International Raceway) is one of the top spots in the nation to get some negative DA (Density Altitude) going. Negative DA it was with -345 feet. If you are on the West Coast or anywhere other than the Northeast it is perfectly fine to feel jealous. Here are the mods: For perspective, a VF tune only F82 M4 ran 11.0 @ 126 at MIR earlier this month but without any bolt ons. The temps start to drop and so do the times! If the owner goes to race fuel and drag rubber he can definitely improve on this result. He shouldn't be laughing at VF only holding the record for days though. In a few days he might be on the receiving end.

    Yup totally understandable! I had a hard time figuring out if it was a full ring or not. But it's crazy escpecially since it was during an open lapping day. I wonder how this compares to an m4 or 1m of similar mods.

    Yeah definitely can be improved. Just wanted to point out it's a BTG lap so people don't get confused and think it is a full run.

    The McLaren 720S is absurdly fast. Watching it destroy everything it runs is starting to get a bit boring. It needs some stout competition. A heads/cam Viper certainly is stout but this is an ACR which is built for the track and has a ton of downforce. That rear wing is creating drag that is not helping in a roll race. Furthermore, even with upgraded heads, a tune, exhaust, and an aggressive cam this naturally aspirated Viper is making less power and torque than the stock 720S. Throw in that the Viper has a manual and you get the result you see here. It's time for the 720S to start going up against stronger competition.
