Glad you got it up and going !

I removed the CDV on my E92 335 and I couldn't believe the difference... I could never understand why they would put that in in the first place, seems so stupid.

I need AWD for the Canadian winter to drive all year round - and to rip off the line in less than perfect or wet weather. I believe the N55 turbo has serious limitations and it is not performing consistently. I may have some issues with sensors or something, but I believe the stock turbo is just too weak and I should have gone your route out of the gate. I also have to run meth to get my results, but I really don't like running meth for safety reasons (IE: getting rear ended).

I bet I would have paid marginally more. Is it rude to ask how much roughly you have into to just the engine components (PS2, fuel pump, down pipes, exhaust I think you have) - is it roughly $10 or 12k US?

My buddy has a 2018 440 and his B58 is way way stronger than the N55. It's a better turbo.

Thanks for describing your goals so clearly, it is a real service to all of us.

To be honest I don't know exactly (and I don't want to know really ha) but I did a quick round up and yes that seems about right for the performance aspect. I was able to get decent deals on some things, but I've also done a lot of pioneering and self funded product testing myself (have done roughly 50 dyno pulls on my car through the various stages) and part swaps (mostly tune related - Jb4, about 3-4 tuners via BM3, had problems with my old forgestar wheels way back but i did get fully refunded for them thankfully after a lot of headaches, etc.) with trial and error along the way. At the end of the day, I've been doing this a while and (despite what people will say) I rather pay more for quality parts and have it done right the first time. I work with an amazing shop that hooks it up and I am thankful to have other players that can spread their knowledge and expertise into my passion and put 100% into the car. You can definitely save money doing work yourself (trust me I've done a lot over the years - interior swaps, brake jobs, suspension swaps, turbo swap, exhaust, etc.) but I'm at a point now where if I can't do it or it's a major job I'll leave it to the experts.... I also have absolutely no time with my career and other things in life so it cuts into that. This is an added expense I have (and many people will probably not be doing turbo or clutch swaps for example). Lastly - I like to give back so other people may not need to go through some of the issues or hassles I did, or at least make it easier to educate them on it. A lot of great information on here and various boards so it's definitely helped.

With you being EWG, stock turbo is pretty good up to around 400whp ish with the proper octane (give or take obviously) - a bit more with ethanol mixes and meth, but you are straining the stock turbo and putting it beyond its efficiency at that point. Turbo upgrade is really the best option if you want well into the 400s and 500s reliably, but there are other factors that come into play that most people neglect or don't want to see and then complain about it later on. For example, PS2 was great with all the supports, but remember then you need the tuning and then the fueling, etc. to get the most out of it... I would also recommend some sort of suspension upgrade to help put it down (maybe brakes but I guess I'm getting carried away now). In my situation (6 speed) I also needed an upgraded clutch and now my rear tires will need replacing soon (I can light them up through 2nd pretty easily now from 40mph hits)... so you see how one that may lead to another and that creeps up on you real fast unfortunately - so be prepared for that and enjoy it for what it is!

They add it for people who don't know how to drive manuals properly ... I did read they added it in years ago when they were covering clutches as part of maintenance or warranties at the time so it would help minimize clutch riding and slipping and in essence help them have longer life span. If you are properly driving manual, it has no negative impacts on the clutch.

I was playing around with the custom burble slider in BM3. Here is a little clip of my setup. Sounds pretty insane in person, but sometimes I think it's too much for me (either I'm getting old or I just like to hear the turbo spool more vs burbles ) ... The great part is at least I can tweak them to my liking. I'm back to OEM style for now.

I may be getting old too because when ever I hear heavy burble cars I can only think of the SRT-4 guys from years ago where I'm pretty sure that's the only sound their cars were capable of making. They all popped and backfired like crazy

Apparently the BMW crowd loves it too

Nice to be able to turn that off when your wife or mother (for some people the same person...) gets in the car and you want "normal". Then you get evil, turn it on and give er a RIP ! Nice.

Yessir! The burble settings change with the different driving modes for on the fly changes. Comfort/Economy = no burbles and sport/sport + = burbles

Updates!!

Clutch is finally broken in and we can continue tuning

I have been getting a lot of PMs regarding the new XDI HPFP... I created a new thread on it. So anyone who is interested, go check it out!

https://f30.bimmerpost.com/forums/sh....php?t=1563313

The TTFS XDI pump is holding 20-21 psi the whole RPM range on PS2 turbo. This is only on 93 octane

Still dialing in the setup, we just started upping boost and damn the car is a missile! This is a nice setup for even pump gas setup. Once we start throwing more octane at it (ethanol mix or race gas) we can bump the timing up more aggressively, but trust me the car is quite fun as is

Here is my setup from this morning - 20+ psi at 6.5k rpm on 93 octane pump gas - fuel pressure is perfect.

And yes.... we are planning an ethanol tune as well

New tires for the back! Went for the meaty look and fitment... plus I need more traction so I went wide. No rubbing!

Rear Specs: 19x10" et 40 with 285/30/19 tires, -2.0 camber

[puReturbo5]

makes me want to pure turbo an f30. great build!

[DaFish]

The fitment is absolutely perfect... nice work as usual !

Love the new Meaty look my friend! I have 275's on mine and about to drop her down. I'm aiming for a similar fitment, I love your ride! I'm Also doing the M-sport Front January, trying to get on your level

Thank you sir!! Enjoy the process

[F30_SixSpeed]

Here is a side by side comparison of stocker vs. XDI-35 hpfp. Both logs have same hardware parts (aside from the upgraded pump) and are both in top of 3rd gear @ 6k RPM (same exact speed too - that was actually a coincidence)

You can see the stock HPFP would dip/crash on anything above 16-17 psi (sometimes associated with a rough fuel cut and buck - I'm sure a few of you know what I'm talking about lol). I'm running 20-21 psi on the XDI-35 pump and no fuel pressure dips at all. Car feels real beastly up top at 20+ psi with solid timing too .

Dyno numbers coming

[sean2648]

Those fuel numbers look great. They really made a great product in that pump. Now hopefully it can come down in price and not be more than the turbo upgrade itself.

Good to see someone doing it the right way though. Amazing build once again.
