Would like to thank all of you who volunteered to clean our bathroom UNTIL you found out we used windshield washer fluid for the “Frosty Down the Sh***er” picture. Damn it!!

VP “Stay Frosty” Down The Sh***er!
Decided to change motors in our modified last week. Realizing we had $35/gal Frosty in the motor it became a challenge to recover every drop. We carefully removed the pipe plugs to drain the block. BAD NEWS, ¾ of a gallon ($26) down the “sh*tter”! It was all over the floor resulting in a big mess to clean up. It was impossible to get plastic container under the drain holes. The solution!! Called my buddy at the surplus store who found a hex fitting that will screw into the block and gets your drain point away from the block and over the pan rails. The fitting is steel, sticks out less than an inch and allows precision draining into a container. Figuring everyone has the same problem, we decided to put a kit together with 4 fittings and sell it for $12.00. If you buy it with VP Frosty you will get a 20% discount on the kit. ( If you have already bought Frosty from us the 20% will apply.) On our UMP motors with an aluminum Olson pan we use an additional 45 degree fitting that sells for $6.00.

Time To Get Tanked & Releave Those Butt Aches!
Every racer knows he should change the fluid in his Bert or Falcon transmission every 3- 4 nights. It is cheap insurance. It is not hard to drain but it is a pain in the ASS to refill. Lay on your back with a wrench, funnel, hose, pump, measuring cup, flashlight and a roll of paper towels to clean up the mess. The solution!! We had a small DECK mounted aluminum tank built that allows you to fill the transmission standing up on the outside of your car. Pour your fluid in a measuring cup, unscrew the cap and dump it in. (NOTE: Be sure & have “the wife” get down there & put the drain plug back in!!)

Water Temp Guage Causing Stains in Your Underwear?
VP Racing new product Stay Frosty Coolant may be your solution! It is NOT an additive, instead it REPLACES your current coolant. Stay Frosty is designed for high heat racing engines. VP claims up to a 30 degree reduction in temperature. Our SCP A-Mod was running 230-240 degrees after a feature. We built a shroud, changed fans and even removed the screen in front of the radiator. Still the same temps after a race. In desperation, we bought 3 gallons of the Racing Stay Frosty. Drained the old coolant, filled it up with Stay Frosty and off to the races on another heat wave July night. Results were pretty amazing, first night we ran 200 degrees and the following week on a heavy, heavy track we ran 210 degrees. “Praise the Lord” no more STAINS!!
