I agree, I am not even bashing CSF's products, I think they make good stuff. Just can't stand their empty promises and attitude/marketing they have towards it. Plenty of people with more money than brains fall prey to it.

Just installed my new Mishimoto cooler. I'll tell you - I'm stupid picky when it comes to welding and material quality. This thing is top notch and priced better than the CSF one.

You can see 8hp differences on the same dyno with different ambient temps on different days. Csf makes a good product. .

CSF makes a good product in my experience. One other option that not many people on here mention is Garrett. They have data on there cooler showing that the stock unit is very efficient. Garrett is a Tier one OE supplier as well.

I recently had mine installed along with some Eventuri carbon charge air pipes. I should also mention that I have the Dinan heat exchanger on my car.

If my stock charge cooler taps out post warranty, this is the only aftermarket unit touching my S55.

I agree that C&R is pretty piece, but $4K is pretty damn expensive too. I'm sorry but I'd only buy C&R if I was an endurance racer. Otherwise that $4K buys you a top shelf Wagner TMIC plus their large and small FMIC kit (with the air duct too).

Is there any data on the C and R intercooler? I have zero qualms with the stock cooling but love to tinker and feel cool with Gucci parts.

I have a dumb question, and Iím sure someone here will acknowledge that itís a dumb question. A few people have kind of alluded to this, but maybe not fully addressed. Since the CSF has higher volume capacity than stock, doesnít it require more air flow to push through the unit to reach any full benefit? If the stock unit is simply swapped out and replaced with the CSF and then run on the Dyno for comparison, is it really a fair comparison? Was the tune on the car customized for the setup with the stock unit? If an OTS tune, was that developed with the stock unit installed? Wouldnít the better comparison be to optimize the tune for the stock unit, run on the Dyno, swap out for the CSF unit and then optimize the tune for that unit and re-run on the Dyno again with hopefully similar climate conditions and then compare? I guess that was more than one dumb question...sorry!

Thereís nothing in the tune to do with a better intercooler. It either works or it doesnít.

@gdawgg
To add to landonvan all the map (stock or tune) cares about is the IAT produced by the TMIC and the outgoing pressure at the manifold, not TMIC flow, volume or such (but those things are relevant).

You do hit on the scientific points of increased liquid/air volume versus pressure/flow versus fluid/heat dynamics. Maybe that's why top shelf TMICs use polished tube/fin (Wagner comp) or bar/plate+turbulence (CR)...to increase heat transfer, since the bigger volume slows down the flow in the bigger core.
