ones too fast according to CHP!
Renncoupe,
You are on the right track! We just tested a prototype intercooler upgrade for the C32 as well. What we found was what you are looking for. We saw better a/f ratios (right at 12.5) and we were able to make a ton more power (20HP) and torque (30LB) in 3rd gear up (that is where the heat was building up to kill power).
You can see the dynos here:
C32 Power Chart (stock v. evosport pulley v. evosport pulley, evosport intercooler, colder plugs)
C32 Torque Chart (stock v. evosport pulley v. evosport pulley, evosport intercooler, colder plugs)
C32 Torque Chart (stock v. evosport pulley v. evosport pulley, evosport intercooler, colder plugs)
Unfortunately, we will not be making one for the C-Coupe as few seem willing to pay what it will really cost to do it right.
We can certainly do them on spec though, but the $500 price tag is WAY optimistic for the amount of labor and the parts cost, as I am sure Randy would agree!
Thanks
Brad

C230 K Coupe
Look how much profit ASP has gotten because they sell $350 pullies. Its all volume. If some of the bigger brands were around $400-450 instead of $1000 for a nearly identical product, they definitely could have generated more profit (or still can 
), selling 2x's the number of goods and exposing customers to other items that are for sale, its additional advertising. The same thing that happened to pullies can happen with Intercoolers...especially with awesome dyno numbers. Volume sales can be a good idea for this product market.

You don't need to spend a ton of dough on an intercooler. The core that Randy and Mark Cummins are using you can get from a local Spearco dealer for about $442 (list price). Then either have a place make end tanks for you, no biggy. Or you can send the specs to Spearco and they'll add the end tanks on, a completed assembly is $640 with that core. Remember, this is the retail price, wholesale in any quantity to a dealer must be less. So if a place like Evosport or Renntech want to carry them, they should be able to make a profit selling them for full retail, anymore and you are getting gouged. That's just my opinion, same opinion I had about some overpriced pulleys.
Also, I'm not impressed with those end tanks. It looks like the fairly high speed airflow has to make a radical 90 degree turn in and out the core. It would appear that a great amount of turbulance would be generated. I think it should be more similar to stock where it's a smooth bend in and out of the intercooler. I hope they took the time to flow test them.

Mark priced the intercooler from spearco and got a price of $852 and that did not include the clamps and hose ect. I expect to see the price of the full kit around 925 complete with every thing you need to install the intercooler.
The 90 bends on the tanks for the intercooler do not effect air flow at all. This is a closed system underpressure air turbulance is not an issue you have the same pressure on both sides of the system.

OK, assuming that the airflow on those end tanks is not critical, then why are you pursuing replacement tubing for the entire run? It's not a closed pressurized system, it's one that's flowing a few hundred cubic feet of air a minute. If there are any restrictions it will just backup to the s/c. Not saying that it's not way better than stock, just saying it can be better. It just looks odd that they made the end tank in a wedge shape and then put the inlet/outlet tubes on the narrowest part of the tank. Is there space restriction that didn't allow them to make the end tanks square?
