JBR under car piping video.

[Redline]

Hate to say it but @Tokay444 called it.

Indeed. The question is, will that "balloon-cycling" eventually lead to a failure, or is it okay for normal operation over an extended period of time?

 

[f1puertorico]

this could be a solution.

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

No idea... Cuz "low bats"???

Ease of manufacture and flexability to accomodate multiple setups.

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.

I have the JBR one piece cold side. Subbing.

I think freektune blew that section out at the drag strip.

he blew the cobb one

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.

 

[Beans]

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.

 

[Gandalf]

I'm not concerned about power lose or lag but over time I believe the repeated expansion will lead to failure.

 

[JgamB]

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.

 

[Faeker]

I don't think expansion over and over again would help with the parts life expectancy.

 

[Redline]

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.

 

[PoonFlavoredTang]

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.

 

[neganox]

Ugh. Someone said treadstone kit. Gross.

 

[PoonFlavoredTang]

Here's something. Red line is a BNRs4 and Blue line is HTA3586. These are from a 3rd gear pull for each. One has solid pipes and the other is JBR piping. After seeing that video it has me wondering if this is why they are matching up so well. Anyone have any spooling data for a BNRs4 who has hard pipes?

 

[Koke382]

Damn lol. Saw on fb too. I think he also said something about aluminum pipes also expand. Lol
