This is the Vacuum Pump used by the last 8 Straight IHRA Pro Stock Champions!

Manufactured from 6061-T6/651 aluminum, hard anodized and Teflon coated this pump is designed to be light, reliable and efficient. Our Mountain Motor Pump will out flow and produce higher peak vacuum than any racing vacuum pump with a comparable chamber size.

Our intake and exhaust positions and internal porting are key to this pumps efficiency. The intake and exhaust ports are placed tangent to the rotor and are (internally) configured differently. Our unique one piece aluminum shaft/rotor is proven to be lighter and more reliable than 2 piece (steel/aluminum) designs which are prone to fastener failure and key/keyway wear.

The rotor bearings are mounted outside the pump chamber with an additional seal on each bearing. The addition of this seal is required to increase vacuum potential and eliminate the grease in the bearings from being "sucked" into the pump.
The pump housing, rotor and end cap have been hard anodized to eliminate wear, then Teflon coated to reduce friction. Our intake/exhaust plate can be configured for -12 AN, -16 AN or 1" dia. slip on fittings. In addition our regulator is mounted to this plate, eliminating the need to place (cut/weld) a regulator receptacle (bung) somewhere else on the engine. There are two major benefits to mounting our vacuum regulator directly to your pump. First, when the regulator set point is reached, ambient air is drawn directly into the pump helping it run cooler. And the other, by placing the regulator "outside" the crankcase area, the excess air the regulator is bypassing will no longer be passing thru the engine to the pump. It now flows directly into the pump, reducing the possibility of oil being scavenged from the engine. Shown with mounting bracket STR.02.07.004.

Now that you have tightly sealed the engine to achieve vacuum in most cases there is no (sealed) provision to add engine oil. Check out our sealed Oil Fill Cap STR.09.08.000 (See: Products:Fittings/Hoses)
