Intercoolers are a common performance upgrade on boosted applications nowadays, with their installation on turbocharged and centrifugal supercharged combos pretty much the norm. And with factory superchargers now coming with “intercoolers”, more commonly referred to as heat exchangers in modern applications, everyone knows that intercoolers are good. But I am not sure most people really understand what they do and how they do it. Richard Holdener’s latest video is showing us what the impacts are from installing one on his supercharged 3800 V6.
Video Description:
HOW MUCH POWER DOES AN INTERCOOLER ADD? HOW MUCH DOES AN INTERCOOLER LOWER THE INLET AIR TEMPS? DOES A SUPERCHARGER NEED AN INTERCOOLER? WILL A ZZP AIR-TO-WATER INTERCOOLER HELP MY L67/L32 SUPERCHARGED V6? HOW MUCH BOOST CAN I RUN WITH AN INTERCOOLER? DOES AN INTERCOOLER WORK BETTER THAN WATER/METH INJECTION? CHECK OUT THIS VIDEO WHERE I RAN A SUPERCHARGED (MODIFIED) L67 3800 V6 WITH A 3.0-INCH BLOWER PULLEY, SMALL COMP CAM AND TUBE HEADERS BOTH WITH AND WITHOUT A ZZP AIR TO WATER INTERCOOLER. I MONITORED THE POWER AND INLET AIR TEMPS ON BOTH TO ILLUSTRATE HOW WELL THE COOLER WORKED TO REDUCE THE HEATED INLET AIR FROM THE GEN V M90 SUPERCHARGER. THE MORE BOOST YOU RUN, THE MORE POWER YOU GET FROM THE COOLER.
