Useful Race Engine Tech Tips for Racing lovers

During the summer of 2003, an excellent magazine was published by prominent editor Ian Bamse, in which more than 50 countries around the world are wanted. What is race engine technology after all? Race engine technology encompasses all engines and transmissions used in events such as Formula One, NASCAR, Le Mans, MotoGP, NHRA, and World Rally Cars.

Useful Race Engine Tech Tips for Racing lovers

The automotive industry has always praised the aircraft industry's use of lightweight metals, advanced finishing processes, and composites. Because the use of these materials and processes helps to reduce overall mass and in turn achieve good speed, performance, and reliability of race engines. 

Race Engine or anyone's test benefits in maintaining their engine power, overall efficiency, durability, reliability. Electrification, biofuels, CNG, high-pressure fuel delivery systems, combustion air management, turbocharging, supercharging, and expanded use of low-viscosity lubricants are the focus of race engine development. Today I am going to write about Useful Race Engine Tech Tips for Racing lovers after my research and interview with racing engine mechanics.

Useful Race Engine Tech Tips for Racing lovers

Horsepower and Motor Oil Viscosity

Using high-viscosity motor oil may reduce your engine horsepower. It takes horsepower to push thick high-viscosity motor oil through the engine oil passages. Here's an example, you could lose 8 or more horsepower @ 6000 RPM in a Chevy small block performance engine just by using high-viscosity motor oil as compared to a lower viscosity motor oil. In some cases, your engine will not be any better protected using high-viscosity motor oil over lower-viscosity motor oil. Some performance motor oil brands offer zero-viscosity oil. Contact your favorite racing motor oil company for more information. Always follow your vehicle manufacturer's motor oil recommendations.

Valve Overlap Basics

Lengthening engine valve timing produces an overlapping of the intake and exhaust valve events (Both intake and exhaust valves are slightly open at TDC). In the early days, it was previously thought to be inadvertently overpowered. But later, after it was discovered that a mild turbidity effect was obtained from this overlap event, the exhaust actually pulled some of the intake charges. This means more horsepower, my friends.

Internal Combustion Engine Volumetric Efficiency

Volumetric efficiency refers to the efficiency with which the engine can move the charge into and out of the cylinders. It is a function of a number of features, but most notably the size of the valve openings compared to the volume of the cylinder. Engines with higher volatile efficiency will typically be able to run at higher RPMs, and lose less horsepower to get in and out of the engine. 

Is My Engine Running Rich or Lean?

Here is a simple way to see if your performance engine is running too rich or lean. With the engine at operating temperature simply removes a vacuum hose that is connected directly to the intake manifold, if the engine speeds up, the carburetor is too rich, if the engine stumbles or stalls, it's too lean.

Icing the Intake Manifold

I'm sure you've heard of the old trick of placing ice on the intake manifold to cool down and help condense the intake air, cool. The problem is that the ice will melt and get things wet, OK, here's the answer, go down to your favorite camping store and buy some of those self-contained ice packs. Put them in the freezer a few days before you go racing and there you have it, no mess intake manifold cooling. You will be the coolest person at the strip with this trick tip. 

Torquing Head Studs Correctly

Never tighten head studs with more than 10 foot-pounds of torque, 5 foot-pounds will be fine in most cases. Over-tightening head studs may distort the deck and create head gasket sealing nightmares. Always install head studs with the correct stud & bearing lock compound on the treads.

Header Thermal Coatings / Wraps

The reason behind race header thermal coatings and header wrapping tape is quite simple. The more heat that is retained within the headers the faster the exhaust gas velocity will be, thus improving the scavenging effect and increasing horsepower. Exhaust gases flow slower in cooler temperatures.

How To Select a Torque Converter

In many cases using a smaller torque converter will make your car quicker, due to the simple fact of a higher stall speed. There is another reason that you probably didn't think of, a smaller torque converter is lighter, for example, a 10-inch converter is about 5 lbs. lighter than a 12-inch converter, thus reducing rotating weight and improving your car's response. This is the same principle behind a lighter flywheel in a manual transmission car.

Lock Nut Help

If you don't have a lock washer, lock nut, or Loctite for whatever reason, just take a piece of nylon fishing line and place it inside the nut before installing the bolt. This will work in a pinch in most cases, plus the fish will be happy that you found a new use for fishing line.

Criss-Cross Torquing Holley Float Bowl Screws

For a better seal always torque Holley float bowl screws in a criss-cross fashion just like when you torque wheel nuts.

Mixing Nitromethane & Gasoline

Nitromethane is not effective when mixed with gasoline due to the fact that nitromethane octane numbers are almost zero. So if you mix nitromethane with pump gas it will bring down your gasoline octane numbers. Remember fuel racers run nitro almost straight with a bit of methanol mixed in.

Useful Camshaft Tip

If your racer picks up performance when you advance your cam timing, most likely your cam is too big and needs to be smaller. If your performance improves when cam timing is retarded you may need a much bigger camshaft.

Two Bolt Main Caps

If your engine horsepower is 600 or less, two-bolt mains work just great. This handy bit of info comes from a noted engine builder. Don't you love these tips, plus think of the money you'll save.

Thank You !!!
