Your original post , if I may restate it , is how to convert an image or drawing ( 2D part print) to a useable format to program punch press machines to product the image. The old 2D part print can be converted to DFX format. DXF is short for Drawing Interchange Format or Drawing Exchange...

I would do the same. You know the 3 pump system and in racing, ifin it ain't broke, dont fix it

We ran a dry sump in our Cosworth Formula Car for ten years. Do you have cavitation problems with the oil? See air bubbles in t he tank? We blew up many small block Mopars because the oil would foam up bad when it entered the rear of the block oil gallery, passed thru the valve lifters in the...

Pretty good weekend for Indy racing and Nascar

is coolant pump constant or variable by the cnc machine operator? If constant, you now have maximum vacuum setting as it is sucking the drain sump dry. Start reducing the suck hose inside diameter. Who cares if it takes five minutes to suck out all the fluid. At some point you will find...

When researching todays automobile steering one must consider many factors. The amount of effort used to turn the steering wheel is one input. If you desire a faster steering " time" you can change the rack and pinion steering ratio quite easily. Let us say you have a passenger car that will...

from Carroll Smith book - Prepare to Win I used Styrofoam from the hobby store and made my brake ducts. I covered it in fiberglass.

I can absolutely testify that you need to cool the brake rotors! Yes , get fresh air to the rotors and increase the pad life. A Nascar or similar full body car will have 1200° F heat on the right front wheel in a 30 lap race. Heat is a killer on brakes so the more you can do too cool them the...

When I was Product Manager at a gage manufacturing company in the 1980s we sold an andrometer. Made by Sheffield in 1940s. Product line sold off in 1991. Andon - Angular deviation of the radial measurement. It is used to measure bearing noise. US Navy used it to find quietest bearing...

I have sold cnc machines since 1980. Still do! Cost is one main consideration - but...the cost of ownership is important as well. Will this be a production machine or one or two a week? Will there be software updates required and what is cost of these maintenance agreements? I assume no...

Love the Chrysler long ram manifold on the 413 cid B block, circa 1962

Surely, if it is the bottleneck, it is the thing that must be changed, to get improved performance. Really??? Some people are good at thinking outside the box, some people are good at keeping things as they are. This is one of the think outside the box moments. Like hiding two carbs under the...

Balun You and I have had communication problems in the past. How can you say too much air is flowing thru the carb? The venturi is still the limiting factor and thus the bottle neck. Granted, good exhaust headers and a well designed intake may increase port velocity but you can only push so...

In this case you already have aftermarket intake and header exhaust. The bottle neck is the carb itself. You also can use aftermarket camshaft that promotes scavenging. And you must use the 500 cfm carb.

Carburetor CFM A Holley Carb rated at 500 cfm 2 barrel carb has venturi diameter of 1.3/8". There are 2 barrel carbs with 600 cfm and have 1.45 diameter venturi. Looking at the area the 1.378 bore has 5.9 sq. Inch area. The 1.45 dia. has 6.6 sq. inch. 5.9 - 6.6 = 0.70 sq. inch difference...
