Nathanwhit1 Posted Sunday at 08:18 AM Share Posted Sunday at 08:18 AM Morning all is there any differences between an e6 with the intercooler on the side of the block and the intercooler on the front of the engine.

mrsmackpaul Posted Sunday at 10:34 AM Share Posted Sunday at 10:34 AM I would think the main difference is the injector pump settings The chassid mounted cooler types had higher ratings of hp etc I'm sure there are other minor changes but I think the motors are basically the same Paul Quote Link to comment https://www.bigmacktrucks.com/topic/75797-engine-differences/#findComment-579473 Share on other sites More sharing options...

Freightrain Posted yesterday at 12:44 PM Share Posted yesterday at 12:44 PM Two variants of tip turbine. Air only and air and water. I would assume the water is higher HP rating. 1 Quote Larry 1959 B61 Liv'n Large......................

I cannot remember the reason why. I understand that the tip-turbine system cannot be fitted to the E6/4 valve engine.

harrybarbon Posted yesterday at 03:01 PM Share Posted yesterday at 03:01 PM Now I recall the Army engineers believed the side water intercooler was cooler for the trucks in the outback/desert conditions. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75797-engine-differences/#findComment-579539 Share on other sites More sharing options...
