Diesel Site 6.4 Boot Kit
This boot kit is designed to replace leaking, deteriorated boots on the 2008 6.4L Ford Powerstroke. Stock boot material is silicon. However, this type of material is NOT oil compatable. This is unacceptable in our application as the Powerstroke incorporates a closed crankcase vent system. This means oil travels thru the intake and comes in constant contact with the boots. This oil contact causes deterioration and leaks due to the incompatibility of the silicon boots and the oil from your crankcase. In fact, if you have seen an oil mist all over the valley of your PSD and wondered where it was coming from, chances are it was caused by leaking, deteriorated stock boots. The stock boots WILL leak air and oil. In many cases, 3-4psi leaks are very common.
As an added bonus, this boot kit will keep those who put out higher than normal boost numbers from "blowing boots". Higher boost in the PSD can stretch the limits of a saturated set of factory boots and could blow your boots right off. In some cases, guys with numbers MUCH lower still running the stock boots saturated with oil, having lost their integrity and gripping ability can have their boots slip off as well. Not quite as dramatic, but still a bummer. Even a stock truck can have problems keeping boots on if they become saturated with oil.
Our boots have been tested to 60+ lbs. of sustained boost in a PSD with single clamps only and have held. With multiple clamps, higher boost numbers are no problem for our boot kit. These are the same type of clamps that twin turbo setups run.
As with all of our DIESELSITE.COM "Originals", these are QUALITY PARTS. We ordered sample upon sample of hose material and clamps until we were satisfied with the quality of the parts and certain of their integrity in our application. Our boots are made of hose that is reinforced with synthetic fabric. It will not kink or collapse. The special synthetic rubber is exceptionally resistant to heat, ozone, gasoline, gasohol, methanol, ethanol and diesel fuel. It can withstand the engine heat and 100psi boost pressure. This is virtually "indestructable" boot material.
