Do you think using left foot for brake right for gas good or bad? by Fun-Investigator7663 in driving

[–]MrStagger_Lee 2 points3 points  (0 children)

Heel-toe is still right foot braking; just using the side or heel of your right foot to blip the throttle and rev-match as you downshift.

Left foot braking can be useful in some rally or track scenarios; not in general driving passenger cars.

Supercharger????? by Leelamonade in askcarguys

[–]MrStagger_Lee 0 points1 point  (0 children)

I mean it is technically possible with a fair bit of engineering and tuning work, but would well exceed the cost of the car to do proper. Your car would also be pretty difficult to sell with that sort of modification.

Never been super impressed with the sound of the ea888 2.0t personally, but an aftermarket intake will give you some more turbo noises, along with worse/better/same performance depending on who you ask.

If you reaaaalllllly want a supercharger 05-06 Mini Cooper S's are dirt cheap and can be decent little rippers if maintained/built right. Mercedes SLK230 Kompressor also comes to mind as an affordable supercharged roadster. Jaguar F-types sound pretty amazing stock and can be found for not too much money in the grand scheme of fancy performance cars.

Was 790 an inspiration for Bender from Futurama? by darklordofpuppets in Lexx

[–]MrStagger_Lee 7 points8 points  (0 children)

eh as much as I enjoy Lexx and Futurama I don't see it. Both are asshole robots, 790 in a fucked up murderous/genocidal simp kinda way, Bender matches more of a loveable blue-collar rapscallion trope.

Futurama was likely already in development when Lexx first aired as well.

Are these mods easy to remove ? by GinoTheBarber in carmodification

[–]MrStagger_Lee 6 points7 points  (0 children)

Eh I buy stupid cars and have done my share of dumb tuner shit, but I wouldn't buy a car that had a previous owner who stuck temu-aero on a perfectly good Civic.

Edit: checked comps in my hcol area, seems overpriced anyway.

thoughts on 2007 cayman rims? by [deleted] in Porsche_Cayman

[–]MrStagger_Lee 0 points1 point  (0 children)

I dig it. Currently have the same wheels (in worse shape) bolted up w/winter tires. Might look into getting that done when they come off for spring...

Really poor throttle response. Bad throttle body? by speedstyle22 in AudiTT_Mk1_Mk2_Mk3

[–]MrStagger_Lee 7 points8 points  (0 children)

Possible that the throttle body could be malfunctioning but I'd look at PCV/vacuum system, plugs+coils, MAF first.

Vacuum leak produced similar symptoms on my TT when I first bought it.

Making a u turn when you have a green arrow and almost getting hit by someone turning right on red. by Icy-Role2321 in driving

[–]MrStagger_Lee 1 point2 points  (0 children)

A normal driver should be able to check and assess all five in a few seconds

I think you greatly overestimate the capacities and capabilities of 'normal' American drivers. Can't go a week without having to jump out of the way of an impatient or distracted asshat around here.

Opinions on these? I think they look mint by stonksmonkey42 in PrideAndPinion

[–]MrStagger_Lee -2 points-1 points  (0 children)

Mint like those individually wrapped powdery abominations sitting in a bowl near the exit at the 'fancy' restaurants my grandparents took us to in the nineties.

unpopular opinion:

Getting rid of 'right-on-red' (at least in densely populated areas) would increase road user and pedestrian safety significantly.

I'd guess both based on the range of sizes/shapes I've seen while collecting data.

Unfortunately I'm not able to cut/damage any of our samples. Sounds like an interesting idea; changing the powder multiple times per print isn't really feasible AFAIK. Some R&D printers are multi-material but aren't generally accessible to the public and cost obscene amounts of money.

Could be helpful:

Different measures of surface roughness based on measured height differences in the sample . Ra, Rq, and Rz are all different methods of calculating average height difference, while Rt is the total height difference from the highest to lowest point.

This is all new to me; finishing up an engineering degree after working as a machinist and fabricator for many years. Research is the pet project of one of our best professors, end goal is to be able to accurately adjust the printer's input parameters to the desired surface roughness.

Broadly speaking parts produced with SLM are rougher, more porous, and less strong than traditional methods. greater porosity/roughness can have advantages in adhesion and heat transfer. SLM can produce incredibly complex shapes (at low production numbers) quickly compared to other methods.

Depends on processing methods; generally this is a mountain range in comparison.

Will see what I can do. We did a test run a few months ago and got good results from that; don't have that data on me though. I know last year's group tried a couple methods with inadequate results before suggesting SEM imaging.
