Absolutely brilliant reply, Jack!

I built a 493 CID Chrysler Wedge engine with Quench. I had .060" piston to head clearance. Compression ratio was 11 to 1 running unleaded pump gas. Had cold air intake. Fastest car I ever drove. Estimated 630 HP from similar Stoker 440 cid engine. Cam had .613" lift. Big CID engines love lots...

Excellent reply Jack Smokey Yunick did some very good research on his vapor engine. I suggest good read. https://www.hotrod.com/how-to/hrdp-1009-what-ever-happened-to-smokeys-hot-vapor-engine rm

Go / No-Go gaging is direct and generally simple. If the Go fits (Fig. 1) and the No-Go does not (Fig. 2), the functional thread is in tolerance. The potential for problems occurs when the product begins to drift towards the extremes of the tolerance. This is when a better understanding of the...

Number one way to ruin a rod bearing is to spin up the engine to high RPM before the oil is warm. Let the engine temperature rise to normal operating temperature before getting into the throttle. The S65 Con rod Bearing clearance tolerance (set by BMW) is 0.027 - 0.076mm ( 0.001" to...

As with all things Government is involved with, confusion. The Old ANSI standard was 1 1/2 turns. two turns Max. Then the newer standard permitted 3 turn maximum and NO FORCE. My guess is the manufacturer did not like the high scrap rate caused by 1 1/2 turns. Read the link below for...

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...
