Which supercharger design/brand do you fancy Veeky Forums?

>anything but a direct crank driven supercharger

Twinscrew does not equal roots friendo and I don't think twinscrew has been around that long
Roots are cheap dependable and very good at making horsepower
But the twinscrew is proably the best supercharger you can get if you got the money they are really the only supercharger that actually creates boost while the roots just shoves air into the engine
My favorite is a littlefield 871

Are the Whipple 2.9 liter blowers quality?

I see them getting put on everything V8 in my area.

I think partly because they sell the blower, injectors, air to water intercooler, all supporting parts and chip flash for about $7500.

How do they compare to other blowers?

positive displacement

instant power

Twinscrew is a modified roots.
I really don't want to write a book tonight. Maybe if I had everything copypasta'able I would explain it all in detail.
I was covering the basics in my alcohol induced, happening weekend stupor.
BTW, top fuel superchargers are estimated to be a 900hp parasetic loss.

this kind

Whipple is a brand (founded by Art Whipple) of twinscrews.
Excellent blower.

>900hp
at what RPM tho?

As much as I love the looks and instant torque of a PD blower (roots/twin-screw), most kits just aren't designed to handle extended periods of full-throttle boost which either leads to high IATs (and limp mode) or your engine just plain overheating. They're fine for street driving or a few passes at the drag strip, but they just can't handle the demands of a road course. Even factory-supercharged cars like the c7 zr1 and Mustang GT500 either overheat or go into limp mode when pushed hard for an extended period of time.

That's not to say you can't use a PD blower for road racing, but it usually requires some serious upgrades and/or re-engineering your car's cooling systems.

That's why I like a Vortech or Procharger setup with an air-to-air intercooler. IATs remain fairly consistent and you don't have another heat generator sitting right on top of your engine. Interestingly, the self-contained oiling system for the newer Vortech and Procharger units actually run cooler than the older models which share the engine oiling system.

Both Whipple and Kenne Bell make great twin-screw blowers. Whipple tends to be more popular because it's a bigger shop and has better customer service, but Kenne Bell makes just as good a product.

12,378.296 rpm¿

Posters like you are the reason I still lurk Veeky Forums. Thanks.

neat info.

Only run an intercooler if you're ++7psi, otherwise you'll lose more charge density due to the increased volume of the cooler and duct work.
After 14 pounds you have to run it. 7-12 is debatable.

Old 6cylinder diesels were typically inline. Is that what you meant?

I agree that centrifugal are superior though.

That's true to an extent, but an intercooler allows a high-compression factory motor to handle more boost in the first place due to the cooler air charge. Without an intercooler, you can only run 4-6 psi (YMMV). Running more than that won't be worth it because the decreased ignition timing required to prevent detonation on the warmer air charge will offset the larger amount of boost.

FYI, twin-screws used to beat the pants off of roots blowers due to the lower efficiency of the latter. Eaton units were nicknamed Heatons due to all the heat they generated. However, the newer Eaton designs are considerably more efficient. I saw a test between a similarly-sized newer Eaton unit and a Whipple twin-screw and it was a wash overall in terms of efficiency. The Eaton was more efficient at lower RPMs, while the Whipple was more efficient at higher RPMs.

Nope, I mean v6 2 strokes.
Can't see the turbo but I'm not having luck finding pics that show a clear shot of the super and turbo and exhaust ports.

Turbos are superior to superchargers

General question about superchargers, why do they seem to result/run less boost than turbo chargers? When I hear a person's build with a super charger, they usually run 5 to 7. Meanwhile, turbo people including myself run like 20 pounds of boost. Is it the delivery method of superchargers or do they make the air even more dense than a turbo? How come they produce low boost numbers but still produce good power/torque increase?

None
Supercharger shit is shit

Give me turbos for superior power, cost, power delivery and reliability any day

faggot

faggot number 2

Of course they are, but they become a pain in the ass when you're dealing with a v6 or v8 due to the additional exhaust bank. You either have to merge the hot side piping into one pipe or go twin turbo, which increases cost. Either way, you're dealing with a more difficult install that often requires eliminating or moving a bunch of crap in the engine bay. Some cars even require major suspension modifications just so you can use forward-facing headers.

The amount of boost you can run has less to do with the method of boost and more to do with the engine itself. A high-compression naturally-aspirated factory engine with shitty rods and pistons isn't going to handle much boost before running into problems. Expect somewhere between 6 to 10 lbs of boost max on pump gas. An engine that was designed for boost, on the other hand, usually has lower compression and forged rods and pistons, so it can take somewhere between 10 to 20 lbs of boost on pump gas.

Keep in mind that a supercharger is run off the engine crankshaft (usually by a belt, but sometimes by gears or directly connected to the crankshaft), which means that it actually takes power to spin the supercharger. A turbo will make more power for the same amount of boost because it's using exhaust gases to spin it. There is still some loss in efficiency due to exhaust restrictions with a turbo, but nowhere near the power losses involved in spinning a supercharger using the engine's crankshaft.

Turbos any day of the week, much harder to instal and tune for but the power output payoff is so worth it.

My roommate has a Whipple on his Yukon. Pretty nice.

At the expense of trashing throttle response
>inb4 just learn ur car

I drive for fun, NA is life.

In denial stupidcharger faggot

Neato thanks dood

Name one 4 second turbo car.

Why do the valve covers have covers?

Goddamn this is nice.

How hard and costly would it be to supercharge a car? Vs turboing it?

Rotex, there is a nice kit for my car available (and on order)

VW G-Ladder because I have 2 of them (well I have 4 of the superchargers but 2 cars with them)

look at this supercharger cuck having a meltdown kek
thats why you should go with inline 6 master race

>"I-I make no power b-but at leats I have response!!"

the cucks in NHRA banned turbos, just like they did with OHC

AESTHETICS. You know, for people who never look under the hood that need to be 'wowed' with excessive extra parts, complications and labour costs.

It's retarded. People who can work under the hood are punished, people who can't are rewarded with a massive slap across the face for their ignorance in the disguise of 'muh edokated perchiss'

Turbo's ruin sound

I'm being pedantic here, but superchargers were actually first made to pump air into mines before being applied to 2 cycle diesels.

SC is about half as expensive when all is said and done
