I agree
One reason a good intercooler costs a lot of money is cause it takes time to make. And if you want to make money you have to charge for that time. Duh
I am certainly not going to work for nothing.

As im4duke noted, I have one of the GSF intercoolers and am dyno testing tomorrow. I'll post the results back on this forum. Just so you know, I bought solely for price and perceived ability to chill the air, not any real analysis. In my datalogging I don't see any rise in intake temps during full boost so it seems to be doing ok. I haven't checked it for drop in boost or contribution to lag. It isn't the cleanest looking intercooler I've ever seen, but the price is right. More tomorrow...

I got my IC from Bell, designed by Brian Keith Smith (if I remember correctly). The IC came to me, delivered in 11 days, for $1100. I had to weld the mounts.
I've found that a dyno is a poor test for an IC because of heat soak and no matter how many fans you have on it, it does not simulate the road or track. During my last dyno (an engine dyno), the enclosed room could move 11,000 cfm of ambient air but this was still not enough to keep IAT temps in check.
In addition, I use a GT2 tail which bathes the IC in plenty of ambient air. Rarely do I see temps more than 10C over ambient in the car.

So, what's the design goal with the GT2 tail? To simply flood the engine compartment with more air? Or does it push air up thru the I/C?

Speaking of geeky, I like to open the tail right after a hard mountain drive and feel how cool in the IC is where it meets my throttle body pipe. There is a big difference between that side and the turbo side.

Jesus, $3-4k for a larger intercooler? Did Ferrari by Porsche or something? If you price out the bare materials for a core and end tanks, depending on the quality of parts, the parts alone are generally anywhere from $500-1000 for decent quality stuff like a Spearco core. So at $3-4k those guys are charging a ~300-400% markup, simply because they are reputable people and know that there are few other retailers for us to choose from. I can understand $1-2k for a very nice IC, as it takes time and skill to weld aluminum nicely.
Looking at the Goingsuperfast IC, I have to side with Slownrusty. The end tanks could be a little more round, though I doubt if there would be any significant improvement in horsepower or drop in intake temps from doing this (at least not a $2-$4k difference!). Plus, on top of that Goingsuperfast wins as the coolest company name IMO, so that has to be worth some points!

I originally thought the inlets on the GT2 tail supplied air to the turbo intakes on either side. I'm curious if it was dedicated to that purpose (shroud, air box, etc) or just open like it is with mine.
Anybody have a picture of a GT2 Evo engine compartment, sans IC?
