Do you regret choosing your power adder?

You numbskulls are mixing up turbochargers and superchargers again. The bov doesn't work the same way....

I think the Hot Pink would look best on you darling followed by the dark pink, it would really bring out the void behind your eyes

Looks like this thread has devolved to insinuations and gone sideways long enough ....

Prehaps One Should think about locking it since people just cant walk away,

but, but muh ad impressions! These threads are what paiz da billz man!

What are your thoughts on the Home Depot Husqvarna kits everyone's been raving about?

Everyone seems stuck on Whipple and ESS, but this looks to be pretty cost effective alternative...

my god, the blower is electric! Where's the premix 2-stroke?
Maybe he was inspired by the latest in Formua-1...

Since im so dumb and youre so smart, riddle me this

supercharger springs are -2 and -3 yes?
-6 and -7 and on are turbo, right?
So what happens when i put a -6 or onward on my supercharger application?

or are you saying the spring is so strong and mighty it physically wont fit my supercharger tial?

those are recommended setups, and clearly say in the notes not to use the -2 and -3 in a turbo setup as the pressure will push past the spring power

not the otherway around using a -6 onward in a supercharger

Its devolved because there is an internet troll among us so we are trolling back

the ones with actual contributions get real responses back

its the internet, if you cant handle it, move onto the next site or thread

If you use a stronger spring in a supercharger application, it won't stay open at idle, because the vacuum for the engine can't keep it open. And worse it won't open enough when you close the throttle and you'll beat your impeller up.

On a turbocharger you want the bov closed at idle. On a supercharger you want it open. They do different things in each setup.

You are BYPASSING the compressed air on a supercharger applications

You are blowing off built up pressure on a turbo when you close the throttle because there is nowhere else for the air to go. Once you get the "whooosh" it closes and stays closed because the turbo isn't making any boost because you closed the throttle

On a centrifugal car as long as the RPMs are high you're making boost so that needs to still be let out as long as the throttle is close. So you get a constant shhhhhhhhh because it's always letting the air out in that case. Even at idle, you're not making boost but it's sending more air than your engine needs.

not on a centrifugal supercharger, on a turbo you'd be correct.

They make wastegates for cenrti cars too.

The BOV is open all the time, not just at gear changes. All the time there's zero demand for boost, like when there is vacuum in the inlet manifold.

There's flow going through the supercharger all the time the engines running. The only time it builds boost is when the valve closes. Like when the throttle opens enough for the vacuum to decay enough for the spring pressure in the BOV (recirc or bypass) to close the valve. It won't make boost until that valve shuts (it works the same on a pd, it's just integral to the supercharger).

So, if you alter the spring tension, you alter the vacuum required to keep it open and the effect is getting the boost in quicker on a lighter throttle input.

Don't confuse increasing boost pressure at lower rpm for throttle position.

Ofcourse, if you go wot with any spring (within reason) there's a maximum psi depending on hardware but we've now diverted on to throttle sensitivity and boost. So that's how you can adjust it.

If you bov only closes under boost it's set up wrong. But hey you do you.

So now your implying that a stronger spring will eventually make it not work, beating the impeller up due to surge

so what happened to your earlier comment about “you can run a centri supercharger without a bov if you want” but when i wanna change the spring in my bov, its not possible and im dumb for it

can you please collect your position and stay on one side of your argument instead of jumping on both sides, its making it hard to keep up whos side youre on

 

[robvas]

I said you can. I never said you should.

People do. Early kits came that way. Same with turbos. But nobody recommends it anymore (because they know better). Hell some early turbo cars came from the factory without them. Only ran like 5psi.

Just like people used to not run intercoolers. You can. But should you?

 

[StickShiftyFifty]

your set up is so good. Love it. Must be a blast to drive.

have you got a boost curve shot from on the dyno or a log by any chance. ?

I made a post about my setup , https://www.mustang6g.com/forums/th...-hellion-top-mount.153484/page-2#post-3899606

Thanks, it was a bit of a journey specially since i did alot myself

That's interesting, amazing low down power. Torque like a truck!
