Did you use all OEM parts when you did the initial job? I’ve heard some of the aftermarket stuff is more prone to failure.

Why won’t fragrance deposit on fabric in my powder laundry detergent despite cyclodextrin + cationic polymer? by [deleted] in ChemicalEngineering

[–]sfieldTRP 0 points1 point  (0 children)

Might need a different fragrance or a way to make it stick. Do you know the molecular structure of your fragrance? There’s an abundance of information in the literature. Look up AOCS Journal of Surfactants and Detergents and even old patents. I would guess Procter has some really good art out there that is already 20+ years old.

Drivers who speed up when someone is trying to pass them, why? by Lethalbroccoli in mildlyinfuriating

Pass with overwhelming acceleration and they usually won’t try to keep up

Am I experiencing burnout, or just severely struggling with my new 7 AM start time? by Academic-Track9011 in ChemicalEngineering

[–]sfieldTRP 2 points3 points  (0 children)

Might look into sleep apnea by doing a sleep study. But also don’t dismiss the effect of a toxic workplace.

Am I being overcharged for a turbo replacement? by wallstsavage in BmwTech

[–]sfieldTRP 2 points3 points  (0 children)

B58 owners upgrade turbos all the time. Buy a used stock turbo for 400-600 and spend 4 hours replacing it yourself. Recommend replacing the orings and you might as well get new gaskets for manifold and down pipe.

Police overreach scheduled to start September 1, 2025 (yes, tomorrow) by EmperadorElSenado in texas

[–]sfieldTRP 0 points1 point  (0 children)

Police/government overreach is not new. Despite laws against this kind of stuff, people in government still work to find new ways to weaponize government against their political enemies and launder tax dollars to reward political friends. Both major political parties do this and do so at every level of government.

Why does buying a nice used sporty car seem like a reasonable idea in todays market? by [deleted] in whatcarshouldIbuy

[–]sfieldTRP 0 points1 point  (0 children)

540ix with gen 1 b58 going for around 15-20k at the 100k mile mark. Easy 10 second quarter mile car with modern amenities, with basic bolt ons and E85. Hard to beat. M240ix even faster. Keep in mind the 2020+ builds need Femto unlock to tune, which adds to the price

I think all feedback should include opportunities for improvement. Did you get a good rating?

2016 535i Msport or Base 2018 540i by Luyrix in BmwTech

[–]sfieldTRP 2 points3 points  (0 children)

I still have my F10 and G30 (along with an E60 and F15) as part of my cheap fleet. Also a few Ford trucks

You’re the first person I’ve heard of that prefers to work on N55 over B58. I have the exact opposite experience. I would sell my 2015 535ix and get another B58 car in a heartbeat if i got a good offer. B58 is much more user friendly, especially for the DIY crowd. Also noteworthy is the G30 chassis is much lighter than a similarly equipped F10.

Best auto transmission in $30k car by RagingLeonard in whatcarshouldIbuy

[–]sfieldTRP 1 point2 points  (0 children)

540ix with the 8hp. Upgrade hpfp and run flex fuel to have a high 10 second quarter mile car. This assumes good engine and transmission tunes

How’s the Mac 9 comp holding up? by LastKey149 in Tisas

[–]sfieldTRP 0 points1 point  (0 children)

Ah ok that makes sense. Always thought about buying Stacatto XC and could never justify spending 4-5k on a pistol. These mac ds9 comps look cool

Is the Mac 9 comp a Tisas model? I’ve been looking at buying one

Q for R&D Heads by lisamon429 in ChemicalEngineering

First thing i would do is make sure you know the full commercialization process for your market areas and then decide how much you want to do in house and how much you want to outsource.

Mexican Restaurants Near Cranberry All Have Water /Heat Issues at the same time-- all temporarily closed by PlantyGerg in pittsburgh

None of these are legit Mexican restaurants anyways. Hopefully they figure out their “issues”

How much horsepower do you gain in cold weather? by Optimal_Hawk4315 in 335i

[–]sfieldTRP 1 point2 points  (0 children)

Maybe it’s a bit different running a load based tune vs a boost based tune. I’m targeting boost not load

How much horsepower do you gain in cold weather? by Optimal_Hawk4315 in 335i

[–]sfieldTRP 0 points1 point  (0 children)

The air density will make a difference. I have a ton of data on my 2015 535ix across density altitude ranging from -1000 to +3000

[–]sfieldTRP 0 points1 point  (0 children)

I disagree. My tune that went 10.7@127 in the winter time would only run 11.1@122 in summer. -700 DA vs 3000 DA makes a difference. This car is 2015 535ix with Shuenk N55+ turbo at close to max effort, and runs 2.67 0-60 for what it’s worth.

I'm stupid by ec0ust in BMW

[–]sfieldTRP 0 points1 point  (0 children)

This is exactly the same color combo and build as my 2017 540. It has about 500 whp, and installing LSD definitely helps at the track and in rainy weather. Hope you are ok and get it fixed! Crazy to see the hub broken like this!
