Blower or Nitrous


As a Hot Rodder only one thing matters and that thing is power! Everyone wants more Power, hot rodders, mob bosses, women, the Soup Nazi, and even Iron Maiden became powerslaves (why did they have to die, why couldn’t they just live on)! Anyway we know that more power means more speed and better performance.
            In the Hot Rod world two of the easiest ways to make power are Nitrous or Supercharging (theres turbo too but we will get to that another time). Both have there advantages and disadvantages and there are a few types of both.
            Superchargers have been around for a long time, since the beginning of cars themselves! There basic concept is simple, be either an Air Pump or a Compressor for an engine. Normally Aspirated engines taken air by atmospheric pressure, what a supercharger does to an engine is either pumps or compresses even more air into an engine!
            For Superchargers there are 3 different types of them that are used. The first type is the Roots Supercharger. The Roots Supercharger is as old as the automobile its self, maybe even older! It was first invented by the Roots Brothers as an air conveyor for mine shafts back in the 1880s, since then it has been used in all types of cars and racing. Roots type Superchargers are easily identifiable, usually seen sticking out of the hood of classic muscle cars or hot rods. They usually come in a 2 or 3 lobe rotor design and are best for Low RPM power.
            The 2nd type of Supercharger is the screw supercharger, the screw blower in looks similar to the roots but works differently. The roots works more like an air pump and pumps burst of air into the engine working as where the screw works more like an air compressor that steadily flows air into the engine. The screw supercharger makes most of its power at low rpm and very high rpm.
            The other type of Supercharger is the Centrifugal Supercharger. The Centrifugal looks like a turbo and works similar to one too. However instead of using exhaust to build pressure they are belt driving buy the crankshaft, which spins the impeller, which then dischargers air out into the motor. Centrifugal Blowers work the best in mid and high RPM ranges (similar to turbos).

Nitrous
            Nitrous has a similar concept to a supercharger, which is getting more air into an engine but it works in a different way. The chemical formula for Nitrous is N20 (Two Nitrogen Atoms and one oxygen atom), what the one oxygen atom will do is oxidize additional fuel in the engine. Nitrous is usually stored around 900 psi in a pressurized bottle and it is stored as a liquid, when the liquid gets in the engine it cools way down which increases the air and fuel mixtures density allowing it to burn faster and make more power! Also despite the common myth that nitrous is flammable and explodes its not! It actually makes an engine less likely to detonate!
The 3 different types of Nitrous are Dry, Wet and Direct Port.
How Dry works is only nitrous is injected into the intake manifold. No fuel or air is added. This is good for low horsepower increase for about 30-50 HP. Wet Nitrous works by injecting nitrous with fuel, this is the most common for carb engines (since a nitrous plate has to be placed beneath the carb aka the plate system). Last is Direct Port Nitrous (aka Fogger) which nitrous is directly inject through each intake port in an engine this system is usually used for all out race cars.
Now which is better for your engine? Well both will give power right away and both have there Pros and Cons.
The Pros for Supercharging are:
Instant Power when you hit the throttle
Minimal Maintenance Cost
Easy to Install Bolt on Kits
Works great with Carb, TBI or EFI
Extremely Durable

The Pros for Nitrous are
Low Start up Cost
Instant Power
Easy to tune
Easy to hide

The Cons for Supercharging are
High Start Up Cost
More Violent Throttle Response
Adds Weight
Takes up more engine room
Nitrous Cons
Bottle Refills will get expensive
More Maintenance
Limited use for each bottle

So both are great for making more power, really what it all comes down to is preference. Whether you want to install a supercharger or go the nitrous route it all depends on your engine building skills and style.

Hot Rod Transmissions

Did you just find a 41 Willys body?, or are you building a 33 Chevy Hot Rod or do you have an old Dodge Coronet that you want to restore?  Maybe you have a 55 Chevy that has a TH400 in it but you want a rockcrusher or a lenco racing transmission. If you are on a tight budget but need a transmission, buying one used or even junkyard shopping is going to be your best option (unless you got an inside connection on how to get a Lenco for cheap that you might want to let me in on, hmm). Anyway you may have to go looking for a transmission but you may be not sure how to find one.
Step 1. Research- Make sure you know what transmission you want for your build. Make sure you know all of the varations and changes from year to year of that transmission. Everything from bolt patterns, drive ratios, length, and other things can be different on the same model transmission from different years.
Step 2. Learn About Transmissions- This step really is common since, but it is a step many people do not do! Learn about how a transmission works, what a transmission does, the different parts of a transmission. Plenty of info is on goole and I am sure there are Youtube videos on basics of transmissions as well.
Step 3. Plan out the build- Make sure you know what parts you are going to need to install your transmission. Make sure your transmission will bolt on to your engine and to see if you will need an adapter or not. If your transmission will require those parts make sure you get them before you install your transmission to have them on hand.
Step 4. Inspect the Transmission- Whether you are going to a junkyard or to pick up a used transmission from craigslist. Try to bring with you someone who knows something about transmissions. One you get to your transmission be sure to inspect, even bring a flashlight with you to inspect the inside. If the transmission you want is still in the vehicle ask the junkyard staff to see if they can pull it for you.
Inspection Automatic Trans- When Inspecting an Auto Transmission remove the drain plug (its usually small, so this is where studying transmissions helps), drain the fluid, check to see how dirty the fluid is. Turn the transmission upside down and remove the pan, check the condition of the input shaft. Also check the internal rotating gear assembly. Move the transmission through all of the gears both up and down, the transmission should go into all of the gears if it is good. Also look for any cracks in the gears or the transmission as well. Inspect the gear teeth for any wear or damage. Make sure the output shaft rotates as well, also when doing this listen for any grinding, or meshing noises. If so this may not be a good transmission.
Inspection for Manual Trans- Inspecting a Manual is the same concept as an Auto but with a few differences. Again remove the drain plug and drain the transmission. Look for any pieces of dirt, small pieces or metal or anything else in the gear oil. If the gear oil appears cloudy or milky there could be water (and of course rust) in the transmission which is a bad sign. Inspect the condition of the input shaft for signs of the bearing failure. Again shift through all of the gears in the transmission both up and down to make sure they work (don’t forget reverse).When shifting look at the output shaft, it should spin when you shift into gear. Also listen for any grinding or mesh noises if you don’t hear anything and no derbies in the gear oil and no problems you most likely have found a good transmission!
Step5. The Build- Now that you have your transmission and hopefully the parts you will need its time to install it in your Hot Rod!

Rat Rod Rockers!

A while ago I have talked with director and writer of D.A. Sebasstian about Rat Rods and others things when he ask me If I would like to review his latest movie Rat Rod Rockers! I was interested so I agreed to. I am not big on underground and “campy” style films but since this one is about Hot Rods I had to give it a shot (plus free DVD, who would say know to that).
            So I got the movie in the mail a few days later, a long with pictures of some pin-ups (eye-candy). The DVD cover and it has that old style B-Movie look to it, so that’s what I was expecting.
            The movie is about a family the Mildues (seriously that’s there last name) who by a property in Anywhere, Washington that they do not know has money from an moonshiner named Old Man Kanker ( seriously that’s his name) and the Mad Kats car club are hired by the Russian Mafia to find the money from the property but the Mildues having just moved in makes this difficult.
            The movie is low budget, the quality isn’t Hollywood quality but is much better than phone or home camera quality and the acting isn’t great.
            There are a lot of Hot Rods in the movie! A lot, everyone in the small town owns a hot rod, even the Mildues own a 56 De Soto as there daily driver. There is  a black Model B Sedan, a 56 T-bird Gasser with a 514 big block stroker!, a Tri Five Chevy Gasser, a roadster and many other Hot Rods!
            I was disappointed that there wasn’t a lot of car action or car talk in the movie. The Hot Rods where used as just regular transportation and daily drivers. There was a short drag race between the 56 Hot Rod to Hell T-Bird and a 55 Chevy, as well as the only car chase I ever seen that started with Mr. Mildue spying on the Mad Kats and the Russian Mafia, trying to take a picture and he accidently Honks his horn and it ends with him running out of gas (I am not making this up).
When I was watching the movie I wasn’t sure if I liked it at first when I was watching it. It seemed really home made, with goofy acting, and a simple plot. I was disappointed that there was only one race scene, and one car chase and more foot chases in a movie titled Rat Rod Rockers. However after I watched the movie I kept thinking about it for a few hours afterwards and it became funny to me.
            The bad acting, the goofy names, the foot chases,the Character of Harold Mildue  it all seemed funny after I watched the movie. I actually started laughing about everything afterwards. Would really made the movie great was Harolds goofyness, the character tries to be the stereotypical 50s TV Father, however it seems more like his mind is stuck in the 60s. He is naive, light hearted, always happy even when he is locked up by the Russian mafia, he doesn’t seem to have a care in the world.
            Other things that I started liking in my head was the Mad Kats Car Club and there “leader” Jimmy Knight’s determination to get on the Mildues property for the money any way possible. From trying to poses as government officials to claim the property had radiation which Harold doesn’t believe them, he tries get the Mildues out of the house long enough to go look around on the property which again back fires, so he decides to just try and kidnap the Mildues.

            Overall I liked the movie, when I first heard the name Rat Rod Rockers I was expecting a movie more like Two Lane Blacktop but in one town, with Rockabilly bands (the trailer on youtube showing the drag race also made me think of this) but instead I got an entertain, and very funny thriller film with lots of Hot Rods. The Film could be considered a parody of thrillers. If you like goofy, campy humor, low budget films, hot rods, rat rods, surf rock or rockabilly I recommend it!

PS the theme music will be stuck in your head for days!

Bonneville Speed Week


What is Bonneville? You may have heard or seen this name a few times before. You probably seen the name on a Pontiac and just thought it was some fancy name for a Sedan. Maybe you have heard the name Bonneville on the History Channel, and because of this you learned that Bonneville is the name of the Salt Flats in Utah where scenes from Independence Day, and Pirates of the Caribbean: At World’s End.
            Little did you know that the Bonneville Salt Flats are Americans Ultimate Proving ground, a place where machines built as wild as you can imagine are tested, a place where you can run anything to see how fast it will go as long as you have the guts to stay in it!
            The Bonneville Salt Flats are the remains of what was the prehistoric lake Bonneville. Thousands of Years ago, the lake dried up and has been the Salt Flats. The flats are named after Benjamin Bonneville, who was an Army Officer that explored the Oregon Trail.
            Since 1914 Bonneville has been a proving ground for top speed and who can ever build the fastest things on wheels. The First Bonneville Land Speed record was set in this year by race car driver Teddy Tetzlaff.
            In the 30s Bonneville gained nationwide attention when American racer Ab Jenkins and British racer Sir Malcolm Campbell went out to compete for speed records. This got the worldest attention and by 1949 an official track and annual events where now being held at Bonneville.
            By this time, the Famed So-Cal Speed Shop had started building Coupes and Roadsters just for Bonneville. They were 32 Fords painted there famous red and white. In 1948 So-Cal Speed Shop built the first bellytanker meant for top speed, it was a Belly Tank from a P-38 fighter aircraft and powered by a Mercury V8. So-Cal later built the first Streamliner in the early 50s powered by an Edelbrock equipped Mercury V8.
            By this time in the 50s many Hot Rodders where now build cars just meant for the Salt Flats, usually 32 Ford Coupes and Roadsters. The parts company MOONEYES even made a wheel just meant for Bonneville and Top Speed known as the MOON Disc. The MOON Disc is believed to help Increase top speed and versions of it are still used today on many cars at Bonneville.
            In the 60s the 300, and 400 MPH barriers were broken and man was going faster on land then it had ever dreamed! However Man wanted to go even faster and soon Jet and Turbine powered cars were appearing in the 60s at Bonneville. Guys like Craig Breedlove was the first to break the 500 MPH, and 600 MPH Barriers all using Turbine powered 3 Wheeled Streamliners known as the Spirit of America.
            This record was then broken by Gary Gabelich in 1970 with his Rocket Powered vehicle Blue Flame. Blue Flame would go 630 MPH and the record would stand or 27 years! It would stand till 1997 when a team of British engineers built a vehicle known as Thrust SCC which was powered by two Afterburner Rolls-Royce Spey engines broke the sound barrier on land, which is still Bonneville’s fastest record today!
            Today Bonneville still exists and everything from Jet Cars, to Streamliners to diesels to even traditional style roadsters still make runs at Bonneville. Once a year the Southern California Timing Association still hosts the 6 day long event know as the Bonneville Speed Week.
            There is a lot more History to the Bonneville Salt Flats. From Motorcycles like Burt Munro’s Indian, to generations of Hot Rodders and Cars that have made passes on them. There is just so much about the Bonneville Salt Flats that it is Hard to fit it all in one article!

            Bonneville is a name known by every Hot Rodder. It is a Historic Land Mark and is part of mans desire to go faster than before. It was a place where the Imagination can run wild with Ideas and dreams can true.
