What does an Exhaust X-pipe do?

What does an X-pipe do?

X or H both are balance tubes which are meant to help the scavanging effect of your exhaust system. X-pipes are less invasive towards flow and tend to yield better Peak HP…H-pipes actually cause a bit more turbulence but to the effect of netting slightly more backpressure increasing TQ.

Honestly I think all too oftern both are arbitrarily placed where they fit best over wher they work best by most exhaust shops. On my  ImpalaSS I had the H pipe welded and removed 4 times until I had the best location. The best location for it proved to be a place not very accomodating to ground clearnace but still netted almost 6 RWHP more over the original location which best “fit” under the car.

I know professional race vehicles spend hours of dyno tuning and complicated math to find the “best” location for these balance tubes.

Poly Bushings VS Rubber Bushings


Poly vs. Rubber

We all know what it’s like to suffer from sore joints. Even if you’re in good physical condition, without enough cushioning between your bones, ordinary motions can be difficult. Now, apply that same concept to the suspension on your old car or truck. The bushings found on the control arms, leaf springs and various mounts are like the cartilage between your joints. The manufacturer normally equips a vehicle with rubber bushings, which provide a soft ride. Over time, however, the rubber begins to wear from oil and other contaminants under your vehicle, and the suspension components start to bind. That’s when the automotive equivalent of arthritis sets in, and your vehicle’s performance suffers (not to mention your own level of ride and handling comfort). Worn bushings are one of the major reasons for road wander. Rubber bushings may crush down before the suspension can respond to a bumpy road, allowing for play or wobble.

Benefits
For more precise handling and firmer control on your resto project vehicle, installing polyurethane bushings can make an enormous difference because they help to maintain the right alignment of caster, camber and toe, even on rough or uneven pavement. Polyurethane bushings can be used in a wide variety of suspension components and also in mounts for the body, engine and transmission. They can be used on virtually any type of vehicle, domestic or import, and despite their small size, they can have a big impact on your resto-mod project.

Another advantage of polyurethane bushings is that they’re virtually impervious to oil and other road contaminants. These units will not crush down or wear out like rubber bushings, and are designed to be free-floating, rotating 360 degrees, so the suspension can articulate fully without binding. In contrast, rubber bushings are often bonded to a metal shell and sleeve, and function with a twisting action that, when pushed to its limit, binds up instead of rotating freely like urethane units. Rubber bushings can even induce wheel hop from the spring-like action of the rubber twisting back and forth.

Tools & Tips
What does it take to install polyurethane bushings? All you need are some common automotive tools and a basic knowledge of auto repair. Polyurethane products usually install just like their rubber counterparts. Depending on the product, it can be installed in as little as a half-hour, but may take as long as four hours in some cases. And, of course, an automotive repair shop can also do the installation as well.

By the way, when a vehicle is raised or lowered beyond its stock specifications, the original rubber suspension bushings are at greater risk of failing. The OEM/stock rubber usually can’t withstand the forces of a vehicle setup at a non-stock riding height. Polyurethane bushings are better suited for the weight transfer and shift characteristics of raised vehicles. Depending on their application, polyurethane bushings can be formulated to a specific “hardness” (known as durometer). By formulating different levels of durometer strength, they can be designed for specific needs, be it a street rod, off-road truck, sport compact, or even a hopping low-rider.

In addition to tightening up the suspension, polyurethane bushings provide improved turn-in and cornering response. Also, polyurethane body mounts can help to reduce body roll, a real plus for lifted trucks. In some applications, they can be used to provide extra clearance for larger off-road tires, with or without adding a suspension lift.

So whatever type of “joints” you have on your vehicle, consider upgrading them with polyurethane bushings—they’re a sure cure for your vehicle’s aches and pains

Can I run an overdrive transmission in my car without a computer

The answer is YES.

Vehicles that came from the factory equipped with these transmissions did not use a computer to control the transmission. The confusion comes from the fact that the computer in the later models controlled the 12v circuit to the transmission for converter clutch lockup.

You do not need a computer to run one of these transmissions! You will however, need to get a lockup wiring harness. We make a very simple and easy to use harness that can be installed in 15 minutes and will provide the lockup operation.

Can You Tell classic car Clone From The Survivor?

The muscle car clone is on the left but do you know what that means? The survivor is on the right. Both are beautiful muscle cars. Do you care which one you buy?

Here are just some of the common words you will find when reading classic car advertisements or talking to used muscle car sellers.

aftermarket – parts made for your car by manufacturers other than the original manufacturer; for instance, putting an Interstate battery or a Fram air filter in your muscle car is using an aftermarket product, aftermarket products are often used in resto-mod projects

car corral – a section at a car show where individuals and/or dealers are selling classic american muscle; a great place to find a muscle car clone or a survivor

clone – a car that has been modified to replicate a muscle car, an example of a muscle car clone would be turning a basic Plymouth Satellite into a Plymouth Road Runner or a basic Pontiac into a Pontiac GTO Judge; the modification can be as simplistic as using exterior details such as badges and stripes and adding hood scoops or it can be completely re-building the basic car to meet the factory specs of the target classic car; these are also referred to as tribute cars

daily driver or grocery-getter – a classic muscle car that is driven and enjoyed on a regular basis; typically not a high value low-volume vehicle that had limited production or is worth lots of money

NOM – not original motor, generally this indicates that the original motor was replaced with either a period correct motor from another car or a newer motor; some muscle car buyers would not pay as much for a car that was NOM

NOS – new old stock, original equipment manufacturer parts that were made specifically for the vehicle but that are no longer available through the manufacturer; these can be found at car shows in the swap meet area or online through eBay and parts sites and are sought by people who are doing a restoration project or even building a muscle car clone

numbers matching – a term that means the engine, transmission and other important components are all stamped from the factory with numbers that match the VIN to prove that the car is all original; be careful with this one…some sellers say “numbers matching” when only one component is actually original, for instance, they engine may be a replacement (NOM!) but the transmission is original

OEM – original equipment manufacturer, this term is generally used when describing parts on a muscle car that are from the original car manufacturer, not aftermarket or NOS

restoration (frame-off restoration) – a car that has been disassembled completely and returned to original factory specs usually including the correct parts numbers and components for the vehicle as it would have come from the factory; lots of time and money spent here but a highly rated restoration is probably worth the price you pay

resto-mod – a combination restoration and modification (or modernization) of a classic car, it typically means that the car has been modified to incorporate some of today’s technologies in the areas of steering, braking, handling, and comfort/convenience such as improved guages or sound systems; it’s not a muscle car clone or a survivor

survivor – a factory original car that typically has low mileage, original engine, drivetrain, paint, and interior components; these cars often bring the most money in the collector car market

Classic Car tips for storing your car,

Freezing temperatures naturally dictate that anti-freeze be used. But even if it’s not freezing, put it in. Many of the newer ‘coolants’ have excellent corrosion inhibitors that will help protect and lubricate your cooling system. A 50/50 anti-freeze/water mix is fine. Again make sure to run the car so it’s mixed throughout the entire system.

Change the engine oil. Dirty oil is contaminated with acids and water that can cause premature bearing failure and rust inside the engine. If the car is likely to be left for a very long period of time unattended, remove the sparkplugs and liberally squirt some form of ‘upper-cylinder lubricant’ into the cylinders before replacing the plugs. This will help stop the piston rings from rusting to the cylinder walls.

Make sure the Brake and Clutch master cylinders are full of brake fluid. Brake fluid can absorb water very quickly. By reducing the exposed surface area of the fluid, the water absorption can be reduced. If you can, bleed the brake and clutch systems. It is recommended that you do this on an annual basis anyway, to purge the system of old and possibly contaminated brake fluid.

To inhibit rust in the engine area, use a lubricant spray such as WD40 to coat all exposed metal surfaces. The volatile carrier in the WD40 will soon evaporate leaving a protective film on the hose clamps, coils, carb bodies etc. ‘Wax-oyl’ is good, but you’ll want to hose it off at a ‘car wash’ in the Spring.

Wash the entire car and apply a good wax. Don’t forget to clean the inside. Do this early in the day to give it plenty of time to thoroughly dry before putting it in storage.

If you have a convertible top, leave it up and the windows and vents closed. A convertible top can develop nasty creases when folded for long periods, especially in cold climates. Treat Vinyl tops with Silicone or similar. Keeping the windows and vents closed keeps small creatures from entering. But buy some desiccant sacs from a storage supply house ‘Dry Pac’ for example and place them inside the car on the floors. This will keep moisture from damaging the interior if it is damp or humid where you are.

Ensure that the boot is clean and dry, The boot seal is not always positive and some moisture can collect and condense in the inner fenders and floor. Air it out well for a day or so, then place a desiccant sac in here too before closing it up.

Finally, take the car on a good 30 minute run. This will evaporate all the moisture in the exhaust and in the engine. Then park the car with the hand brake off and either ‘chock’ the wheels or leave it in gear if necessary. Over inflating the tires can help guard against flat spots. Disconnect the battery.

The best thing to do for a stored car is to visit it once a month and take it for a short drive. This keeps everything in good shape, preventing things from getting corroded and seals drying out. At the very least have some one start it up periodically. If you are going to cover it use a proper Cloth car cover, not a Plastic one. If you find the concrete floor in your storage unit gets damp or ‘sweats’ use cat litter, or lay plastic beneath the car to prevent the condensation from reaching your floor pans.

 Make sure your gas tank is full. This will reduce the amount of water that can be absorbed by the gasoline and it also slows the rate at which it turns to varnish. Use and additive like “Sta-Bil”, “Dry Gas” or similar. Make sure it’s well mixed and run the car for a while to make sure it’s in the entire fuel system

Soda blast vs sand blast

You have options for stripping paint from a car, including sand blasting, which is a messy, abrasive process that warps metal, roughs up the car surface and scratches useable panels. You have to be careful to make sure you don’t get sand in certain areas of the car, especially where there is moisture that can lead to rust.

The time for a sandblasting job compared to soda blasting is significantly longer because you have to cover or remove every part you don’t want stripped. With soda, you can have direct contact on mirrors, rubber, glass and chrome without worrying about permanently changing or damaging the surface.

With sand, you have to disassemble every part and component of the car that you don’t want to blast because the sand will alter, damage and rough up the surface. The time you spend prepping, covering and removing parts to protect them could be spent on something else when you choose soda blasting.

The actual cost of sandblasting might be cheaper, you need to think about what your time is worth and if you would be better off doing other tasks (and making money) while someone else blasts the car and strips it in one shot. Even paying someone to prep that car before sandblasting is generally not a feasible solution either because of the high cost of labor and over-head involved.

The after-blast mess is no walk in the park either. It’s a physical process that can

take a lot of your time away from other projects or cost you in labor to have

someone else do the task for you. Sand is a hard material that doesn’t wash

away easily like soda (sodium bicarbonate) does.

Why use Zink In your Oil?

Passenger car and truck oils are formulated to reduce emissions and provide longer drain intervals. This has been done by increasing detergents and reducing anti-wear additives, but your race engine operating under high load and high RPM conditions needs high amounts of anti-wear additives (Zinc and Moly) to create a sacrificial additive coating that prevents metal to metal contact in your engine.

Modern Engine Set-up:
Decreased anti-wear (i.e. Zinc)

How to determine correct Carburetor CFM?

The carburetor itself has perhaps the most pronounced effect on fuel consumption. Since each carb comes pre-calibrated for a certain cubic inch and RPM range, the best place to start is with the right size carburetor. You can calculate the required CFM using following formula:
Theoretical Carburetor CFM = (Engine CID * Maximum RPM) / 3456
This formula assumes 100% volumetric efficiency at redline, but street motors are more likely to fall in the range of 80 – 95%, depending on head/cam/intake/exhaust selection. Therefore, we should factor that into the equation by using an additional formula: Read more »
