I saw the results of testing done by Accufab that led to the conclusion of the "head cooling mod" being a worthless modification for keeping certain cylinders in a Cobra MOD motor cool because the root cause of a particular cylinder running hot is not due to a coolant flow problem because a coolant flow problem in the Ford MOD motor DOHC cylinder does not exist.One last possibly contentious point, any input on head cooling mod? Necessary/helpful? There are lots out there, though I would probably order from Cobra Engineering if I were going that route. Also brings up The coolant crossover delete idea. It would be really helpful with the bigger blower and larger intercooler water manifold neck. I could either use the ICT billet fittings and ‘make’ a new crossover, or I could use one of the kits that relocates the thermostat to the top side of the system.
Until next time
I would suspect that companies offering a head cooling mod product do so with out any testing to prove their worth because why else would people be selling those things? Therefore, as I continue to collect parts for an upcoming 1000+ rear wheel HP 4.6 Teksid engine build, one product that I will defiantly not purchase is a "head cooling mod kit."
