[QUOTE="Modular Racing, post: 12083330, member: 18904"] The Install can be completed in the car, like many modifications such as headers etc it is tight but can be done. A local customer just did the install and said he removed the intake manifold and used a curved pry bar between the firewall and the freeze plug, once the freeze plug turned sideways he was able to grab it with a pair of pliers and pull it out, he explained it as being pretty easy with the manifold being off. In regards to testing. We have been using this product for quite some time on our new racecar engines that we have been testing. It is is interesting to not that ford built the same exact thing into the front of the block ( a passage to balance coolant flow from side to side), the problem is the water is fed to the engine from the front, by the time it reaches the rear cylinders it is at its highest temperature. This product simply balances the flow and promotes flow at the rear cylinders. We initially noted the problem when our test engine had higher EGT's in the # 8 cylinder than all of the others. The reason for this is as coolant temp rises, evaporation of fuel in the cylinder head intake port and in the chamber (prior to being ignited) is higher, this makes the cylinder run more lean than the others increasing the chance for detonation/pinging. Lastly, the picture below shows the large water jacket (just below the intake ports) surrounding the intake port on cylinder # 5, 6 and 7, note that cylinder # 8 (far left) does not have it, another reason for the higher coolant temp on cylinder # 8 [IMG]http://www.modularmustangracing.com/coyote%20head%20water%20jacket.jpg[/img] For those considering having the engine out of the car or a clutch job done this is a no brainer, the install in this case is takes just a few minutes and this is cheap insurance to protect your engine (new or old) MMR [/QUOTE]
