The whine from a roots supercharger? Or the "pshhh" sound a blow off valve makes? You can only have one.

having a blowoff valve is gay but i'll take compressor surge over sc whine any day.
>>28771651Recerc is even gayer
>>28771656no DV either, just raw dogging boost all day.
>>28771661Based. I remember about 2 decades ago back in school I was explaining to my mate what. "Dump valve" and wastegate are>So a wastegate is just wasting boost?Yes that is correct>We don't need that shit thenHe proceeded to weld up the wastegate of his turbodiesel Opel Omega, it was a miracle nothing broke as he was forcing 20psi down stock internals.
>>28771670Fuckin send it. I've hit 40 psi boost hotdogging around in my shitty old 7.3 ferd with the stock turbo. Egts go up fast though so you gotta use your senses.
>>28771637why not both? twin charged engine
>>28771689Because it's pointless.Combining a supercharger with a turbocharger combines the disadvantages of supercharger and a turbo in engine.It's better to use VTG or even anti-lag.
>micro bepis spinnyboi impeller Vs>19” GigaChad 14-71 huffer
>>28771795But apparently size doesn't matter
>>28771811Time and a place for either really. I like the instant boost and the old school looks of a big old roots, suits my application.
>>28771637Depends. Blower whine over a rumbling V8 sounds cool, PSSSSH-SUTUTUTU on an I5 sounds cool, even NA screamers have their place in stuff like V10s and V12s.
>>28771795>that gigantic long intricately shaped machined part which has to match up perfectlyJesus no wonder superchargers are like 10 times the price of turbos
>>28771954There’s a lot to set up with a blower, rotor to case radial&axial clearance, rotor to rotor timing which is a bitch with a teflon stripped blower…
>>28771637I miss my R53 Mini, shit was so much fun. Never gave me any trouble but at 20 years old I knew I was asking for something expensive to happen.
>>28771972God, superchargers are sexy.
>>28771724but i want whine AND pshhh
I love my blower so fucking much lads
>>28771972Meanwhile the factory which hi-flows turbos literally just has some Indian guy who sees where the compressor wheel is scratching the compressor housing and machines a bit off in the lathe by eye
>>28771982Fuk yess. It’s horny when it makes a fuggin big block look tiny.
>>28772411Forgot pic
>>28771637I think they both sound really cool>>28771795holy shit
>>28772447I want it to put its dick in me.
>picrel
supercharged sounds retarded
My personal choice is NA, however between the two it has to be supercharger.
>>28772449what's this going in a boat or something?
>>28772750he took these pictures from reddit he doesnt even know wtf hes looking at, just another fraud like every ranjeet
>>28772750Yup
>>28772930Damn, don't take that thing fishing near Venezuela.
>>28773379Kek. I live in the north east, had it out in the Atlantic on calm days.
>>28773432geez, how much tinnitus do you have now
>>28773435WHAT??? Meh pretty bad but from industrial shit more than engine stuff. Ear pro is a must in the boat. >cool old front drive blower with Hilborn injection rando pic I seen.
Superchargers sound like a loose accessory belt or a dying waterpump
>weeweeweeweeweeweeweeweewee> vooiloooool vooiloooool>weeweeweeweeweeweeweeweewee
>>28773432Dream fleet
>>28773566>Detroit Diesel has entered the chat The 12v149’s were beasts. Dual blowers and quad turbos. 149ci/cylinder (about 2.5L/cylinder for metric fags).
>>28773845Fucking forgot pic
>>28773555Check’d and yes, Tyrone’s challenger sounds stupid but real blower noise is epic. 5 mins of blower sounds/drag boat pr0n. https://youtu.be/K5OYfbYX3uY?si=phYHHUhk8mupAS19
>>28771637Alternator
>>28772750Was going to ask this
>>28773845>>28773846The supers didn't add power- they were needed to make the 2 stroke functional.That was the purpose of all roots on diesels.Then some hot rodders got the idea of welding some flanges to adapt to gasoline engines and the rest is history.And if anyone is curious- the numbering system is used for engine type/size.First number is how many cylinders, second number is displacement per cylinder.So a 6-71 is for a 6 cylinder with 71c.i. per cylinder
>>28774075>Then some hot rodders got the idea of welding some flanges to adapt to gasoline engines and the rest is history.Except cars have been supercharged since the 1920s
>>28774080Yes Daimler was playing with them in 1900.Read my post again dipshit.I was specifically talking about roots blowers off of 2 stroke diesels.
>>28774112first roots blower was patented in 1860. You're spewing bullshit.
>>28774112"Unsurprisingly, neither was designed with the automobile in mind, or even internal-combustion engines. Soon, however, engineers recognized their potential. Rudolf Diesel used Roots-type superchargers on his eponymous compression-ignition engines of the late 1890s, and around the turn of the century various engineers created the first blown four-stroke gas engines. Per Motor Sport, Louis Renault—yes, that Renault—patented a device to force more air through a carburetor in 1902, and in 1908, American racer Lee Chadwick won a hillclimb with a car featuring a centrifugal supercharger. "Easily googled info. Whatever you 'read' was full of bs.
>>28774141>>28774142Fucking ESL retards.Youre so stupid you dont even understand the topic.I wasnt talking about forced induction in general.I was specifically talking about the 6-71/8-71 series used on 2 stroke diesels. My post is very clear about that.God damn youre a waste of oxygen.
>>28774159ignore them, anon. anyone reading through this thread with an iq over 90 understands what you're saying and sees how retarded these other children are making themselves look.
>>28773846>>28773845Large Detroits just end up sounding the same.Small ones are where the fun sounds are at.
>>28774075That’s why I called it a blower and not a super. It’s a scavenge blower in that application.
>>28774202I worked on a big tug boat with twin EMD-20-645-e7’s big V20’s basically a Detroit on steroids. My cabin was between the funnels, slept with ear plugs in…What a glorious 2 stroke racket they made.
