**does anyone have some kind of statistical breakdown on how effective this upgrade is? is this worth it in the long run and how does it differ in performance compared to an aftermarket heat exchanger?



**smart technical inputs needed for everyone to use**

 

it dosnt really affect performance, it keeps you from heat soakin faster and keeps everything cooler longer, keeping the iat2s down is a good thing for people with smaller pullies.

 

whats the install time about from gm on this?

 

a lot of hours.

the best way i can describe the dual pass is:

when comparing air to water to an air to air intercooler, it's like making an air to air intercooler 2 times as big

 

Not really. That would be the equivalent of adding 4 more cores to our system.

What this does is send the coolant on two separate paths through the 4 cores, with each path covering only 2 cores before heading back to the H/E radiator. This increases cooling by not letting the coolant get as hot before extracting it. A secondary benefit is that it slows down the coolant flow through the manifold, giving it more time to absorb heat, thereby better taking advantage of the shorter paths. Great efficency mod, essential for higher boost/heat situations to help control intake air temps, preventing the power-robbing heat soak you get after sustained full boost runs.

 

Joe has them for sale. Its a pretty easy install, but time consuming. Get a freind to help.

 

I have a stage 2 with a 2.9, intake, 2.5 dp, 2.5 catback, gm extruded and honed manifold, and solid motor/tranny mounts
would it be recommended?

 

yeah, but not really necessary unless you plan on running a smaller pulley. I would reccomend it for anyone, as a cooler charge air temp can never be a bad thing.

 

i disagree. cooler intercooler means denser air. not neccassarily more hp but better response. i know when my iat2's are under 100 the sc is alot more responsive.

 

True. But, all he's saying is that it doesn't add HP. Now, methanol adds HP because it takes IAT2s down below a natural level. I know what you're saying as well; it does actually affect performance as it keeps you running higher numbers for longer periods of time, you're right....I just think he was talking about taking IAT temps down enough to make more power.

 

i was being sarcastic, but thanks for the more detailed explination

 

Sorry, but you're wrong there. A larger volumetric flow rate will cause a greater change in temperature.

Basic thermodynamics...
