Thread: which intercooler

I am after some info guys, which intercooler will be the best for me. I have got some info below from frozenboost.com. My plan is to run around 20 psi boost, the intercoolers below are only a inch different in lenght but the core thickness and hose connections are different, I was thinking of gettting the bigger one but am worried that with larger hose diameter it will have more lag, but will the smaller one have as good cooling effect.



Water to Air Intercooler - 14.5"x5"x4.5", Long Flow (Type 19)
[INT000219]




This impressive Liquid/Air intercooler is better than any FMIC.

Similar in dimensions to a regular length of pipe, this intercooler provides the installation flexibility of a barrel-style water to air intercooler without the added cost and inefficiency.

Almost all of the high-efficiency water to air intercoolers on the market have your intake air changing direction twice. These Long Flow models (along with our thru models) keep it going straight the whole time, meaning your turbo doesn't have to work as hard, with the net result of more potential power.

100% Lightweight aluminum, No Epoxy Used In Core

Recommended for up to 700 CFM
Pressure Drop: Less than 0.1 PSI. This is not a typo! Liquid/Air Intercoolers have incredibly low pressure drop.
Air Inlet/Outlet: 3.0"
Water Inlet/Outlet: 1/2" NPT
Maximum water/air pressure: 70 PSI
The inlet and outlet on this intercooler go directly through the intercooler; preventing the air from changing direction can result in better airflow.
Note: The water inlet and outlet on most water/air intercoolers are BPT threads. BPT fittings are difficult to find in the United States, so ours all come with NPT threads.

Looking forward to seeing how it goes, very compact.
