Hey Guys,

I wanted to bring this thread back to the top to let you guys across the pond know that we have officially launched this intercooler in UK and Europe!

I read a couple people had trouble with hoses slipping off. Whats the torque spec for the worm gear clamps to make sure the hoses are good without over tightening?

Make sure you dont overtighten them, will damage them as nd then they will slip. Also make sure the hose is properly positioned and the clamp is located properly. The bead on the pipe keeps the clamp tighter if the hose even slips a little. We have alot of miles on ours, primarily hard track miles and have never had a hose come off

It wouldn't hurt to upgrade clamps. They're a little better at holding I think.
T-bolt clamps ftw.

i dont recommend going to t-clamps. We have had to fix issues cause by using t-clamps on aluminum piping. Worm clamps is what we use on intercooler piping also, and we dont have failures even on our 750whp+ EVO8 that was pusing 40psi of boost. The problem with T-Clamps is there are too easy to overtighten and will deform the piping and leak badly and only proper fix is to replace the pipe. If you do decide to go with T-Clamps, just dont overtighten, snug them.

I installed my intercooler and noticed indents on the silicone intercooler pipes. I know those are intentional but does anyone know what they're for? Won't that be a dynamic loss in airflow?

@Jason@USR , @Mishimoto
Thanks! I was just about to ask this. I already contacted mishi via PM. I"ll let you know they say.

Here are the pix I took. I didn't go thru 38 pages, but i went back and see some people got the same tubing.

Same, my guess is during the design they modeled the air flow and this design yielded a better flow characteristic.

Or they’re indents to aid in the manufacturing process.

Or defects.

Maybe they can share the solidworks air flow model.

Thanks for your pix! I'm no fluid dynamics expert, but I would think consistent diameter yields better results. I understand it's a tight spot, though.

I took some better pictures;

on the hot side, pass side, this tube has a slight dent. But, as you can see, there's plenty of space in there and clearance wouldn't have been affected if the ID, OD was consistent on the tube.

As for the driver side, the space is tighter, BUT you can maneuver the tube without significantly bending it to clear that area. Even if the dent wasn't there, it may just be touching something slightly. You could probably use some foam or whatever ducting material to protect the tube.

I’m ok with the pipe with the larger indent but I don’t know about the other. And just off the top of my head the shape looks like it would increase velocity. The length and diameter both play a role in general to flow rate, but things change as soon as you hit the Intercooler. For instance the indent could very well also create a slight helicoidal vortex while also increasing velocity.

There is another thread here by another manufacturer that proposed a change to this classic design but I’m not sure things are so “cut and dry” (heh) as I pointed out in my commentary. I did have a couple beers in me, but still.

You were quite wise to defer the fluid dynamics conversation, I always found it possible things could “unexpectedly change directions” at any moments notice.









(Disclaimer: I know some here are not fond of this “air” and “vortex” humor in the wake of the tornadoes that happened in AL, I mean no disrespect).

And just to be clear unless I see the model everything I say is basically BS.

If you are depending on Solidworks to give you reliably predictive modelling of complex separated flows, you are already in trouble.

Exactly what I was going to say.. I run them on my GN.. I have brought this up before an get bashed for everything I say detrimental but there’s somethings that are just cheap ways to ensure quality... I understand everyone try’s to cut cost this isn’t me stirring the the pot but maybe make it an option for better clamps with different price point. Just a thought

I also agree that t-clamps can be overtightened... but anyone that’s used them knows not to over tighten them or should know not to.. I know when I have t-clamps they are not blowing off... ever

I can start with the model and mesh as physical boundaries, and use industry standard cfd (boring) or construct one from scratch for very specific scenarios (more fun).
