Where do you find these couplers!
Has anyone had any experience with these couplers, good or bad? I'm really interested in find these, but havn't had any luck. (Yes, this is the orange SP Engineering FD from Turbo Magazine.. 
) I'd rather not have to call SP Engineering for them, but if I have to..

What are the benefits (if any) to a hump hose connector? Is there a real difference between them and a normal silcon connector (besides $20 a connector!) Wouldn't it cause more restriction.. I guess I'm unsure as to whether you'd butt the two pipes up against each other so the "bump" is not in the airflow, or if you leave a 1" or so space between them so it is.

HKS also makes some and www.BakerPrecision.com sells them too. I think the only benefit is so that the pipes can flex.

The more complex the inner surface the more turbulence is introduced into the charged air. Granted the difference is small, but why would you want to pay more to decrease performance??
In theory, the straighter / smoother / shorter the charged air flow path the better the performance. The basic principle is resistence reduction.

I believe the hump connector is to allow flex in the system. I have them on my turbo charged truck (daily driver) between the intercooler and the engine pipes to allow for flex when on the throttle. Without them the silicone couplers would pull off and one time the throttle body side (after intercooler) coulper ripped from the engine bouncing around seperately fron the intercooler. As far as performance goes, I do not think anybody would be able to tell the difference.
BTW: It is a turbo charged 4runner running 14psi and 35"tires. There is alot of flexing going on at WOT. Things go every which way. I do not think an FD would have these types of problems!! A little stiffer chassis then my truck!
