Could this 90* hold up "suck side"

http://www.stealthwork.com/reinforced-degree-silicone-elbow-version-p-307.html

I asked about the corba head, about putting it on the suck side of the blower and most people said it would fail under heavy loads, BUT what about this other 90* they are putting it on the blow side right at the TB..just an idea??

It will be fine Jeremy. People use those on turbo/blower setups on LS1's all the time on the boost side and they dont fail. The suction side will see less pressure than the boost side. So if they dont overexpand under high boost, I dont seem them collapsing under less suction.

im not an authority in the field but i dont think theres any chance of it collapsing. vortech uses crappy dryer type hose in their kit so i dont think that there is a whole lot of suction on the intake side of the blower. and that looks like some pretty thick walled silicone.

just my $.02

People gain a couple # of boost, and 20+ horsepower by switching out the dryerhose to a hard intake pipe (search for Brad Brand).

From that site "These Silicone elbows are also non-flammable and will keep its flexibility and elasticity"

I really wouldn't want anything flexible or elastic on the suction side of the blower. If your going to go to the effort of replacing it, fab up a metal intake pipe or take it to someone who can. Even if it cost you $100 to have done, the hp/$ ratio is pretty good.

I have a 3 1/2 hard pipe made , i thinking of trying 4" and see if i can get it to fit..

Like I mentioned before, the elbow Jeremy is looking at are commonly used on the high pressure side of turbo kits right before the TB. They are stiffer than people think. Since a blower/turbo compress air, the suction side will be a low pressure area compared to the outlet side of the compressor. By the way, I could crush the dryer hose with 2 fingers that elbow wont crush that easily.

Jon i think your are right with this, It's just i asked about the cobra head witch is close to this 90* and it was collapsing under boost 15+...i will see if i can find the link.

Seems like if the filter isnt a restriction, then you should be good to go...

i think the increase is due to the reduced turbulant air that the dryer hose causes. if you use a smooth pipe im sure it helps a lot since blowers are sensative intake restrictions. i dont think that the elbow is that flexible. i just dont see it collapsing. i dont think that the blower can cause a low pressure strong enough to do it. because blowers are just that....blowers. not suckers.

realquick.....i think we are on the same page.

Having never seen one in person, I don't know how well it would work. The 15# on the pressure side argument doesn't mean much to me... I could suck hard enough on a 20 oz plastic coke bottle to collapse it, but I certainly couldn't blow hard enough to blow it up.

With the location this piece would be installed, it'd be hard to tell if it was collapsing, even it was just a bit. I'd rather do a hard pipe for peace of mind.

I do agree that the filter would have a lot to do with it.

ive done seraches recently, and no one seemed to have the PN for the powerdyne hard plastic unit. so i ordered one recently, and thought i would add this for future searches.

That’s what I'm trying to tell you. A centrifugal blower is made to blow air, not suck it. It is very efficient at blowing air. It’s not made to suck air. This is why it is easy to lose a lot of power by inlet restrictions; it can’t suck hard enough to overcome the restrictions.

Your lungs are, in a way, like a positive displacement pump (like a bicycle pump). Centrifugal pumps and blowers on not like positive displacement pumps.

It’s hard to explain.

Agreed. Take a look at my intake. 4" exhaust pipe and I will never worry about it. Plus, that elbow is a 90 degree. Not to good for flow.

youve got a pretty trick fab job slim. but on the 4th gen f body they are a pretty tight fit down there, so you have to have some kind of 90 on there. unless you put a small (no room for a large one) air filter directly onto the eye of the supercharger. but then youd have to put your MAF on the pressure side which i havent done yet.

and i too agree that a larger metal intake is better. but i dont see the elbow he is asking about being a problem.

slim, what kinda motor work is done to your LT1? internals?

and how much boost?

Schurters....how much boost are you gonna be running anyway?

Thanks SS. The only work done to the internals is a prayer now and then. :) I see about 8.5# at peak. It is holding up extremely well for the time I have had it on there(1 year) and the hp it is making.

I forgot that the 4th gens still use the bracket that came with my kit originally. The 4th gen bracket wouldn't fit on mine due to the steering box so I made the bracket it uses now.

I am going to max out the t trim, still wating for the eng to be finshed...I should see it in the next few weeks...just heads gaskets and push rods left to get

if your going that big with your project then why not just use a 3" exhaust pipe elbow?

I have a pair of 3" Cobra elbows on mine and haven't seen any problems at close to 17 psi. If someone has one collapse, they are either getting it really hot and soft, and/or have a restrictive filter.

IMHO ;)
