Measure the diameter of both the outer inlet and the inner of the turbo and have someone make a rubber grommet that creates a very tight seal.

I think this might be something I'd be interested in. I don't know why I like doing stuff like this... always making things hard on myself

The metal clanking? It's less with my vacuum problems resolved but not totally gone. One last thing I never review the right brace. They sent me the N54. Maybe with the N55 brace it will lessen more. It's def a vacuum setting

My buddy asked me to share my experience in regards to this question. I went with the FTP inlet because another user said he have one and it worked great. So I was cheap, paid $180 vs $400. I spent almost two years frustrated and spent thousands of dollars on testing, diagnostics, replacing parts and changing tuners. I could not make more than 15-16 psi over 6000 RPM with 95% WGDC. Finally figured I will try one more thing before giving up. I contacted AZMCracer for his custom inlet. It is not a perfect fit. I had a shop tried 3 times and could not get it in and ended up mangling the inlet in the process. Took it to another shop and they got it in in about 1 hour. Still losing money in this process for all the install attempts etc. But finally once AZCMracer's inlet was in, my car was over boosting all the way to redline making 22-23 psi. My tuner then had to turn down WGDC a lot to keep from overboosting.

So I guess which one to go with would depend on your priorities and how much boost to you want to make up top. The FTP grommet is a big choking point. AZMC's inlet is only about .3" bigger measuring at the inside diameter from the FTP inlet but this makes all the difference in making boost up top.

Thanks for the feedback! Happy to hear you were making that much boost.

What kind of power are you making? Sounds like you have everything dialed in and a similar build to what some of the guys here are shooting for.

Very interesting info, thanks for the write up and pics. I had seen one other post from someone who had a similar story but then Steven @ Wedge said that, quoting, "the inlet and outlet are not big improvements on F series like they are on E series. The stock parts flow fine."

Happy for you that you found your solution but it's frankly a bummer for me to see that your inlet made such a huge difference - from 16psi to 22psi at the top. With FTP I'm currently around 16 to redline with WGDC 90%+, but at Denver altitude so maybe add a couple psi to make that apples to apples assuming you're around sea level.

I also have az's inlet and I don't break past 70 percent wgdc till redline making 18psi boost. I am only on 3 gallon of e85 + 93 octane.

I have not put her on the dyno yet, but my sport display shows that I'm pegging the 480 HP and 560 TQ needle. When I was making 17-18 psi, my dragy shows a 12.4s 1/4 mi @ 113 mph. I'm still in tuning process with my new tuner.

Yes I've seen that post before and was thinking how wrong he was. I guess he don't have much experience with the F10. With the FTP inlet, I was not able to make more than 16 psi too at 6K RPM and then tapers to 13 psi by 6800 RPM. With AZ inlet, I can make 22 psi at 6800 RPM with 95% WGDC. It's hard to believe a .3" inlet size makes all the difference.

$howtime is selling his AZ inlet and so is BMWdoubles

It seems strange to me you were tapering to only 13 by 6800, I've been almost 3psi higher than that by redline and I'm at altitude which probably knocks me down 2-3psi if we're apples-to-apples. Most recent log: https://datazap.me/u/ahetts/da-fuq?log=0&data=3-19

I would've said it's not bc of the inlet if you hadn't already fixed it by changing the inlet, so what do I know haha

One thing we have to decipher is it ftp version 1 or 2

FTP did make improvements for some platforms, but I don't see a V2 for the F10.

I might be making 15-16 psi at 6800 with my current tuner using the FTP inlet. The first tuner I used was bad. I don't think he knew what to do with PWG.

That's starting to make more sense to me, I was suspicious the inlet swap could account for essentially a 10psi increase at the top.

One of my logs before AZ custom inlet:

Are you PWG and do you know what your wastegate is set to? It looks like we're all getting different result.

[burro_blasta]

With folks like bmw5sport at 23 down to 18, I've been okay with 19+ down to 16 accounting for the altitude here. But of course crucial to know if a better inlet would add a few psi and lighten wgdc.

PepMo, switching from a shitty tuner to a good one is obvi the biggest variable, during that process were you able to isolate the difference of switching from FTP to AZ? Or did it all get muddled together.

Yes I'm PWG. 2014 was the cutoff year to EWG but my car was made a few months before the switch to EWG. Dammit!

bmw5sport tapers down to 18 due to tuner setting the limit up top for now. He's still early in his tuning process.

Yeah, I keep bad records and my memory not so great at my age. I changed out so many parts at various times chasing the boost drop off up top so I can't really say which part helped or not. I went from AR catted DP to ER catless. Traded my Mperformance mufflers for F10 M5 Dual 3" exhaust.

As for custom inlet vs FTP, for sure 100% the AZ custom inlet will make more boost up top. I'm with the same tuner who made the map for that log I shared. I switched the inlet during the tuning process which caused major over boosting everywhere in the RPM band running the same map.

This map is after the AZ inlet install, notice how it is overboosting everywhere.

https://datazap.me/u/pepmo/mhd-e85-m...22-23-24-25-27

If you are happy with 16 psi up top, then you should keep the FTP inlet. However if you want to make more boost, no tuning will get you above 16-17 psi up top with the FTP. Trust me , I tried. With AZ's inlet, you will need to make modifications for it to fit. Your log looks good.

[PepMo]

I could be wrong. I see that David Shoup can get your WGDC to 100%. I've never seen my WGDC hit 100% before so I don't know what boost you will make up top with it at 100%. You should try single gear pull all the way to redline without shifthing.

Anyone have timed their F10 in the 1/4 mile yet? Anyone broke in the 11s?

Wow look at that log

Must be fun... do you have any videos?

Sorry no videos. Yeah it feels incredibly fast for big 4 door sedan with an inline 6. She's a sleeper.

Fun fact I want to share, I recently purchased a Tesla Model 3 Performance model with dual motors. It can do 0-60 2.9 seconds. The instant torque from a stop is crazy. However my F10 feels almost the same and can beat the Tesla after 80 mph.
