@@NoLifeMeta My 340i has the M Performance LSD. This is on my 435i and unfortunately the M Performance LSD was discontinued about 3yrs ago or so. I had Birds Auto in the UK build me a spare unit with a Quiafe LSD.

@@sunbish Around how much did it cost to do that? I know diffsonline has that for around 3k?

@@NoLifeMeta I want to say somewhere around between $2100-2500usd. I can’t recall the exact figure, but it definitely was less than $3K.

@@agxnt7649 I knocked it out with the inlet. Wasn’t too terrible for me, I use to turn wrenches at the dealer so I do all my own work. There’s several detailed videos online that could watch and see if it’s something you want to attempt.

@ yea I saw the videos and a lot of people have to remove the water pump and that just doesn’t sound like fun, did you not have to do that? I recently did my inlet and it was smoother than I expected and got good value out of it, I’m wondering how much better an upgraded bov will be

@ I unbolted the water pump from the bracket and moved it to the side. Wasn’t bad

@@Woo.f32 unfortunately it has been 😭

@@M240Waheed Besides the crappy mpg and “rough ride”, I really like it. Definitely don’t regret purchasing it.

@@championraul No, old fashion brake boost.

@@jensenalbanese796 100%

If used to its potential, absolutely.

@@sunbish yeah im in the same setup as you

@@swagonwheelselites6365 they don’t sound alike at all 😂

It is tune and turbo dependent. For my particular setup, it was 5900-6100 depending on the gear.

@@Woo.f32 That one is back up.

@@sunbish thanks for putting it back up bro🙏🙏

@@championraul It allows the DME to see boost over 21.7psi, it does nothing else. It isn’t necessary for the OTS tunes.

Oh okay, gotcha. Thanks

@@championraul No worries 👍🏽

@@sunbish thanks ,ever planning on working on m3/m4 s55 ? My buddy has 340i mhd e40 but he shifting at 7k plus rpm i gotta let him know

@@lsxracing7744 7k is waaaay too high if he’s on ots e40 with an upgraded hpfp. His dyno curve and power should be very similar to what I did. I’ve thought about it, not too sure yet. I’ve been contemplating a G87 😈

Thanks! I try to spread some knowledge or at least try to help the community have a better understanding on some things that I think might not be spoken about much or explained. I’m by no means an expert, but I am always trying to learn more myself. On my 435i I tried the CTS intake, but the car was not any quicker 60-130 nor did it make a difference time or trap speed wise in the 1/4 mile. I took it off and put the stock air box back on with the drop in filter. I honestly think the front mount intakes work, but they need a custom tune that’s tailored for it. On my 340i, I did remove the stock air box and stock paper filter in favor for a RK Tunes front mount intake. I sadly didn’t get any back 2 back comparisons, as the silencer broke on the stock one so it went into the garbage. The car did previously do a 7.7-7.8 60-130 and was right at 130 in the 1/4 mile on the stock setup, and with the RK tunes setup it did 7.4-7.5 and the trap speed went up to 131. I want to say the stock setup was in -500ft to -800ft DA while the RK tunes was right at sea level. I don’t think that was solely the intake setup though, as I wasn’t previously using drag mode on xHP but I did have that active when the RK tunes setup went on.

@@sunbish I appreciate the info my dude. Maybe after the flex fuel sensor (I’m stage 2+ but run the 93 map using 93/2gal E85 right now) I’ll get the front mount. As long as it doesn’t LOSE power like some intakes seem to, I wouldn’t mind hearing the turbo more. It also looks aggressive af to the eyes looking for that type of thing. I think Stage 2+ with a higher ethanol content and I should be able to drop from 10 flat to mid 8s (1k+ DA) 60-130. That’s my goas. Your car proves it’s in reach with even more meat left on the bone. I just want to stay with a stock 707 Hellcat. That will bury anything but the most modified cars below that level. God these cars are such a good tuner special… they’re really cheap for 500hp and stealthy comfort when you want.

The stock turbo is small.

Be patient 🙂

No, that’s just some car I seen at some apartments that were next door to a cookie store I took my lady to.

Really close but I think the RS3 may have edged it out.

I went 10.2 with 505whp in a very similar car. It would be a sad day for me if I could only do a 10.8 with 530whp in these cars.

@@sunbish don't get me wrong I've seen lower HP cars in the 10s but they are cutting 1.4 sec 60ft but only trapping 98mph. Looking at your videos your 418whp car is around 2.1 sec from 1/8 mile to 1000ft your 500 whp car is 2 sec. How do you explain that

@@Madmalchen you’re looking into at what you want to see. Compare them everywhere 330’ 4.64--4.23 difference of .41 4.63*--.40 660’ 7.08--6.56 difference of .52 7.10*--.54 1000’ 9.19--8.58 difference of .61 9.24*--.66 1320’ 10.98--10.29 difference of .69 11.06* --.77 * = sea level DA The 340i incrementally was steadily pulling away while in DA that was 1800ft or so worse and with zero to minimal wind speed. The 435i had a good tail wind behind it, at least 10-15mph and slightly higher gusts. The difference would be larger if it had equal conditions, which would be more prominent at higher speeds which I just showed above.

@@Madmalchen Here’s how much of a difference the wind speed, and direction along with DA made. 435i in sea level DA with a 5-10mph head wind was trapping a best of 123.58 a week before. All others from this same day were 123.34, 123.38 and 123.36. It went 11.06 in this weather but with a better 1.68 60’. This track bites better, as was consistently doing 1.67-1.71 60’s. Now with a tail wind and -1800ft DA, it did a worst of 125.12 and a best of 125.89, which roughly equates to a 2mph trap speed difference. This track definitely doesn’t bite as good as the other. The 60’ ranged from a best of 1.71 and one other 1.79 which resulted in a 11.05, while the rest were 1.8+. The DA and the wind direction and speed made all the difference. Put the 340i in similar -1800ft DA and with a tailwind, I’m sure the trap speed would be a consistent 132+ and it would ET slightly better as well.

It makes the car quicker, but I don’t know how much it’ll shorten the life of the transmission. It’s one of those things, you take some but at the same time you give some.

@@sunbish do you use it whenever you roll race or is it when you feel it is needed for a certain car your going up against?

Intake IMO is only worth it if you go with a custom tune. I tested a CTS intake and the car didn’t go any quicker with the OTS maps. So I took it off and went back to the stock air box with a drop in air filter. If you have a custom tune that can take advantage of the lower WGDC that it provides, you can push the turbo a little harder and make a little more power. The OTS maps won’t do that, they are preset and looking for a certain amount of load regardless if the intake and exhaust are freer flowing. People have told me to go with a mppk lower that has an additional hole in it. The CTS has shown to lower WGDC as well, but like I stated the car didn’t pick up mph in the 1/4 mile or go quicker in the 60-130 either.

@@sunbish ohh I see, I’ll be sticking with the ots maps for now then. Thankfully my car is an mppk so can utilize that performance lower box. Currently running a BMS intake which translates the sound from my turbo smart quite nicely but I’ll probably end up parting ways with the stututu sound in exchange for at least healthier IAT numbers. Thanks for taking the time to share such a detailed and informing answer to my question🙏🙏
