My IAT with the cx intercooler and meth 19 psi were 77 deg on the dyno making pulls that's with no air flow like you would receive going down the track or cruising the streets

I run the CX 4" intercooler but cut the end tanks off and made my own to distribute more evenly and has 3.5" inlet/outlets. The pressure drop is not much but I do run dual methanol nozzle's.
I run 5.21-5.28 at 138mph in the 1/8th at 3450 raceweight and 20lbs of boost.
It works.

Buy the most efficient IC you can afford.
Just because someone went 7's on a **** intercooler doesn't make it "less shitty". It means the rest of the combo was spot on, they had enough turbo to overcome the pressure differential, and their fuel was good enough to stay clear of detonation at their compression ratio. You'll still make more power per pound of boost with a better core. Put a nice Garrett core on Marks mustang and I'll bet his traps speed goes way up at the same boost level.
Going from the typical Ebay A2A 4x32x12" core to the 1200hp treadstone equivalent made a big difference on my combo. IAT's went from upper 160's to high 140's at 19psi. (sitting at 120+ in the staging lanes)
The pressure drop across the core dropped significantly as well. I know this because I was running an overly tight converter (on a 4.8) and could not make over 3-4 PSI on the trans brake. I installed the TS 1200hp intercooler and went form an LS1 to LS6 intake. With no other changes I was able to make as much boost as I wanted with no other changes to the tune. Not the best example since I changed intakes as well, but below 4k the LS6 and LS1 intakes are almost identical.
I picked up 4mph with an intake and intercooler swap at the same boost level (18lbs) with 2* less timing.

Ideally, you want a core that has the most flow tubes with a relatively short tube length. More tubes means more "area" so less pressure drop. Also, the shorter tubes lead to less pressure drop.
This intercooler is used by many high hp race cars:

Assuming the fins are equally efficient is LxHxW an accurate way of comparing ICs? Mainly in regards to comparing horizontal(cx 31x12x4, 24x12x4 core) and vertical IC(cx twin inlet 24x10x3.5 core)

Now there are many other factors, such as tube size within the core, fin density, etc.

Intercooler is rated by the pressure drop across the core and how efficient it as at removing heat from the air charge. The CX IC does a poor job at both. Regardless of its price or what people have managed to run with one. I'm sure Larry Larson could install a CX IC and run a 6 second pass. That doesn't make it a good intercooler!
Bottom line is It’s better than nothing if you can’t afford a good IC. Same goes for a Treadstone unit VS something like a Garrett.

Totally useless information if your spraying meth on your IAT sensor. Saturated sensors report false low IAT temps. Even the best A2A IC's are only around 75% efficient at removing heat. If the saturated IAT reading represented the actual air temps, it would make meth/water injection alone more efficient than the best intercoolers. If that were true, we could remove the IC’s and pick up tons of power! Unfortunately it’s not true, and a good intercooler will make more power every time.

Not totally useless I was just stating with meth and that intercooler that's what my IAT reads, my meth nozzles are located 15 inches down the intake pipe from my sensor. Yes it may read a little lower than actual iat is but I can't see it being that far off as the air moving the mist of meth at 19 psi the sensor would not be saturated. All I'm saying is for the money it works well and most people are running the intercooled meth combo for the money I would save id invest it to the chassis to get the power to the ground

"Works Well" ? Compared to nothing at all, sure! It doesn’t work well compared to a properly spec’d Garrett core…or even a TS core. Not trying to argue, just state facts for people looking to buy an intercooler. Someone not knowing any better would read this thinking the CX intercooler is great… when in fact it isn’t

Viperslyr: Id be real interested to see what your iat is without spraying meth. I have almost the same setup as you, but on a stock 6.0 bottom end. I have seen the cx intercooler and the price is tempting. But I think I am going to spend the money and get a Shearer Big *** intercooler.

If there wasn't snow all ready on the ground here I would go make some street pulls and just out of curiosity I could take a temp gun and shoot the piping pre and after intercooler before meth nozzles and just see what those temps are. It's not the most accurate way to see how efficient the cx cooler is for lowering temps but it would give a rough idea
Thats cool, we got snow here too. I think the pressure drop will be the biggest problem for our supercharged cars, the temps aren't as bad as the turbo cars. I am planning on running meth with it anyway, but plan to tune it without the meth incase it doesn't work for some reason.
How often are you changing belts on your setup? Iam running the ecs ysi 10 rib with their alternator relocation kit. PITA part was that the alternator didn't fit and Ihad to use a cs130 instead. Also using a madman manual rack and electric water pump, so the belt is real short. Cant wait to finish it up

23ish psi with the 370" motor, but there was also some water/meth added to the mix so that may not be 100% accurate
however I ran the new motor (427") with no water/meth and saw about the same temp and pressure drop at only 13 psi. I suspect the temps to get a lot higher and the intercooler will lose some efficiency once I turn the turbos back up with the new motor.
