Engine-Tech Water Jacket Cooling System

ET is proud to announce this new innovative fully Billet O-ringed water cooler Cover.
The back side of ET Water Cooler is CNC machined to the contour of the OEM housing using surfacing also O-ringed.
Made from 6061-T6 Aluminum, Anodized black for corrosion resistance.
Safely used with all OEM and ET Chargers, we use spacers so that ensures that the casting is thick and strong, 7mm thick or .275 thow.
It's easy to install without any modifications to the OEM Front housing.
Comes with bolts, fittings and orings.
The results are better then expected! Dropped the housing temp by 45 deg in a 20lb setup.
Less boost fade. Improve bearing and seal life also less under hood heat
Very important : Requires a RESTRICTOR before the inlet down to 1/4 or 6.5mm. Out has to be 1/2 id or 12mm all way through out the hull. This is to keep preasure down less than half but good volume.
The Restrictor will be supplied.
Other Aftermarket Superchargers that machine the housing without spacer may have thinner housings.
In that case you will have to restrict the water more.
We At Engine-Technologies inc. are not responsible for any damage that is caused by adding this product to other Chargers on the market. Recommend 3/16 or 5mm restricter before the ET Water Cooler.
You may want to contact your Charger Manufacturer for their recommendations.
Important: In order to use this Product you will have to have the posts, most of the 255 have them. Make sure you have them before ordering!
