JBR under car piping video.

Doesn't looks worst than any OEM boost hose... Don't like the fact that the hose its too long and its subject to substantial flex. That could be an issue if its start rubbing metal.

It's obviously happening. Now if we keep the tune, swap it for say a treadstone kit, would be good to compare hp gains/losses as well as air flow.

this could be a solution.
 
Is there a particular reason it needs to be silicone? Why can't it all be aluminum?

Unfortunately repeated cycling of the material can lead to failure.

The visual effect alone is unsettling. I'm just hoping I have unobtanium silicone on this thing.

The funny thing is, I took a while isolating my cold pipe with some zip-ties to give the coolant line a lot of extra clearance. Seeing how it moves, though, makes me thing my effort was probably in vain.
 
You know, it occurs to me that silicone couplers are seeing my pressure (25 psi) and greater all the time in these mostly aluminum piping kits. The thing is the runs are much shorter, so you don't see this dramatic ballooning visual effect. In terms of durability, 25psi on a 90-degree elbow coupler that 8" long is the same as 25psi on the JBR coldpipe, right? 25 psi = 25 psi?? Pressure is omnidirectional, after all.
 
I donot think anyone truly expected to see zero expansion. But to see if it causes loss of power/flow would be good info to have.
 
Flow won't change much don't think it's a big deal. It ballooning that much is pretty scary, and figure it doing that how many times through wot over time probably wears the silicone.
 
Jamie replied on FB somewhere that it was tested to 40psi for prolonged periods of time and that the inflation generally doesn't increase any more than what you're seeing here beyond 18psi.

I spose I'm going to find out.

I hear ya, but how would this be any different than the forces silicone couplers see in primarily aluminum kits? I think the only real difference is since there's so much continuous silicone, the expansion looks more dramatic.
 
How is silicone effected by temps? Say today, it was 0 degrees here in n.j. And i start my car it warms up amd i do some pulls. Would it still expanded the same? Crack? Pop? Just seems crazy to see that happen.
 
keep in mind it was pretty cool in there. If this is a hot summer day that silicone would be expanding even more. Notice how much it moves going towards the throttle body. It's already a tight fit there and could likely rupture on something.

Silicone doesn't get brittle. However, it'll become more elastic as the temperatures increase. How much would this "blow up" during August versus February is the question. Then throw in more pressure.
