Preparation for the STILLEN supercharger

Zsteve

My Audi TT used a recirculating diverter valve to keep unused air in the system to keep boost up (good for STS too?), and not blow it out into the atmosphere. Is this a viable option for SCs?

I would like to answer this question however, due to the obviously competitive nature of this subject I am going to have to respectfully acknowledge your question but answer it indirectly.

Blow off valves will be an option for the supercharger system however, as 1slow370 pointed out it can cause the afr's to jump crazy rich because you are releasing metered air that you are taking away from the engine. Therefore the engine will supply the appropriate amount of fuel for that amount of air but since you've released it you will be extremely rich. This can actually cause the car to stall at low speed. Which is why we will be offering a dual stage re-circ/blow-off valve. It will be an option.

There is more to this explanation as well but again...We aren't ready to release more info. yet.

1slow370

most low pressure centrifugal setups won't even need a blow off valve which is why it is good that it's optional. They come in handy though on bigger setups but you would just recirculate it from the compressor tube back to the inlet tube after the MAF which would force the air being sucked into the sensor to stand still leaning out the fuel tune

Hey man you need to fix your avatar, the sliders dont work.

Open-atmosphere BOVs sound so cool, though, haha!

lol.. I've been trying to use the damn scroll feature on his avatar all day!! j/k

Kyle I know you said your not ready to go into more detail yet, but I want to hear your explanation on the BOV's. I love the sound of them but have heard a lot of comments about running rich. I am sure someone else can answer this too, but is it really a big concern? Rich is better than lean as far as engine life is concerned correct? Is it merely a problem with running rich and stalling out or can the problem go further than that?

Anyone?

You will like our optional dual stage blow off valves. At low speed, cruising through a parking lot or something, they act as a re-circulating system. But, at high speed like when you're actually driving, they will vent to atmosphere. There is no concern about stalling or anything when driving at high speed because it happens so quickly it's only when you're going slow that the loss of air and excessive fuel can cause the car to stumble and potentially stall.

It would basically be like if you took a breath of air and there was a valve opening up in your throat before it got to your lungs...It would cause you to stumble and fall...

roplusbee

That is a pretty good analogy.

Ya, my damn valve just didn't open right in my throat and I bout choked on my Mt. Dew.. I think I'm with you!

I like what your sayin about the dual stage (sounds nice)....Sign me up!! I can't freakin wait to pull the trigger on one of these bad boys!

Damn, Im gonna miss my SSQV. Is the dual stage external vent a tweet or a sneeze? Not that it makes a difference, but the little ricer in me is wondering

StillenZ

lol I'm right there with you RCZ... I'm trying not to be "that guy" but damn I want it to freakin blow the dust off the road when I shift!

I don't know to be honest...I know that we run them on our GT R rally car and they work really well. If you find some of the video's of our GT R rally car on Streetfire you'll hear them. I would look for them myself but my computer at work doesn't have speakers so I won't be able to hear it.

StillenZ

cool.. I didn't think it was the problem that they were making it out to be... thanks for the answer... can't wait to hear some news at the end of this week!!! I might just drive my *** out to Cali to talk to your "guy" that's holding this thing up if I don't hear something soon! lol

god hydrolocking is never the problem anyone makes it out to be. Experiment for you take an air filter ram it into a sink the next time you wash it with the coupler side up and see how much water gets in. I used to run a cone filter outside of my car (like above the hood) because well the whole supercharger sat above the hood and i drove it on days that seemed like the big man himself was pissing on my car and never had any problems because by the time the water makes it through your filter it mixes with air and becomes a fine mist that just burns right through. I could see a problem if you drove into a lake tho like that Bugatti in the videos.

Edit: and damn right the sliders don't work i wish they did but then i just wander on over to the NSFW thread
