The American Pie Rat Rods Of Yesterday’s Youth Are Just A Past Memory Now

Old men and old times that have thoughts only being kept alive in the minds of our elderly men whom grab up of the dwindling supply of old car bodies to build the vehicle that were the idols of their youth. A “Rat Rod” painted up to look nice or left with the body rust was the in thing. The Hot Rod and Rat Rod are two separate vehicles. The Hot Rod is any car fixed up to look great and go fast but the Rat Rod always has a custom exposed super engine dumped into an old car body. The Hot Rods can still be created today because all you need is to build up the existing stock factory engine with existing installed smog. The Rat Rods always have the stock engines taken out and huge horsepower custom built engines put into them built for drag racing ventures with the engine exposed and chromed for visual candy that can’t conform to today’s smog standards.

Building a “Rat Rod” from today’s high bread messes manufactured isn’t impossible but difficult if you are not up on smog systems and D.C. electrical systems on cars. “It’s The Law” that cars nowadays are equipped with smog systems and you “Cannot” get your vehicle registered if that years smog system isn’t hooked up. Older cars pre 1968’s don’t fall under the smog laws and can be easily sooped up with a big horsepower engine with no smog. The smog systems after the 1968 were easily removed and altered until smog tests came to be. In the 1970’s some states implemented various smog mandates but in 1984 you couldn’t swap engines unless the engines were smog compatible with the year model the engine was being put into. It’s “Illegal” to swap engines from one car to another.

In the days of now complex DC computerized electrical systems control the smog systems and taking out the stock engine and swapping it out for an engine that produces a huge pullback when you stomp on the gas peddle is really difficult to do. With some vehicles if you disconnect any part of the engine wiring the whole car’s electrical system will shut down so putting in a high performance engine would be difficult without changing the whole cars wiring system then you couldn’t get the vehicle smog checked and registered if the new high performance engine didn’t have all the wiring connection points.

Used to be in the 1940’s, 1950’s and early 1960’s you would be able to grab an old car body and dump a huge engine in it and go to the beach and do some cruz’in in a trashy looking rat rod that was cool. The days of ever building a “Rat Rod” out of your garage has come to a close or is coming to a close unless you have the cash to engineer a high H.P. custom engine to today’s smog standards.

I see some painted up rat rods cruising the city I live in once in awhile that are 1920’s and 1930’s car bodies with massive exposed fully customized chromed engines. There’s still some old junk car bodies around to do this but over the next 20 years or so the ability to find these old car bodies or even take a present day car body and create the “Rat Rod” will be impossible. Best you can do is take an existing model year car and remove the fenders and chrome the stock engine but I’m not up on the vehicle safety standards as of yet and most likely it will be illegal to compromise a vehicle’s engineered crash safety.

The Mercedes Tuning – What Are The Reasons To Tune Your Vehicle?

We are very well aware of the shooting fuel prices in the market. Hence, it is crucial to tune your Mercedes, so that it delivers great mpg. There are many reasons of the Mercedes tuning like better acceleration, enhanced torque, great economy, more power, healthier engine etc.

We have seen rapid growth in the technology in the field of automobiles. The super chip tuning technology is developed especially for the premium cars like Mercedes. The tuning is efficient for both the petrol and diesel version of car. It will ensure that your car gives best performance without any hassle.

Importance of tuning

Once the vehicle is tuned, it will reduce the emission and improve the performance by 15%. It is quite obvious that tuning will help your vehicle in multiple ways. However, you must tune the vehicle timely to avoid any inconvenience. The experts recommend visiting to the mechanic once in three months. The professionals will make sure that none of the part needs repairing.

As the fuel prices have increased, so does the dependency on vehicles. It is crucial to keep your car in good shape. If you maintain the car properly, then the car will run efficiently for long years without any hassle. Else, it would require regular repairing that will ultimately lead to lower mpg and reduce the performance.

What to consider while tuning the exhaust system?

The exhaust system of the Mercedes includes a front pipe, exhaust manifold, catalyst converter, silencer, exhaust tip and tail pipe. While tuning the system, muffler is the easiest to deal. The professionals will replace the stock muffler with high performance muffler.

As a result, you will get a free flow exhaust system. You must keep in mind that the inlet and outlet pipe of the muffler is of the same size as front and tail pipe. Check out the diameter of tail and front pipe. They must have same dimensions for better performance. Other terms of the exhaust system is a little complicated to understand. You must have knowledge of the engine’s power band, exhaust back pressure and usable RPM.

If excessive pressure is produced by the system, then it will have a negative impact on the performance of the engine. This will restrict the flow of exhaust gases. As a result, the engine will be inefficient to expel exhaust gases. Ultimately, it would lead to much reduced engine power.

Dos and the don’ts

Make sure that you never attach pea-shooter instead of the exhaust system to the engine. You must also not install a 10 inch wastewater pipe. In case the exhaust pipe is big enough, then it will lead to much reduced flow velocity of the gases. You have to keep in mind to get the exhaust back pressure perfect.

Upgrading the Radiator and Cooling Fan on a 1969 MGB Roadster

In all the 18+ years of ownership of our 1969 MGB Roadster it has never overheated, but a minor leak from the radiator in 2016 necessitated its change so I decided it was the right time to upgrade the cooling system in preparation for the next 18 years.

While checking on prices for a new radiator I came across a company in The Netherlands offering an aluminium radiator for not much more than a standard one, so ordering was a no brainer. Fortunately I ordered this about one month before the British voted to leave the EU and the Pound plummeted against the Euro.

As the whole cooling system had to come apart I thought I would also replace the engine driven radiator fan with an electric one. I have fitted Kenlowe fans to my cars in the past and while they worked perfectly well I had two issues with them. Firstly fitting with their universal fitting kit was never that accurate and always looked a bit untidy and secondly the sensor was an odd bulb arrangement which fitted in the head of the radiator and slotted into an extra seal, which I found difficult to make watertight.

This time I opted for a Revotec fan as it fixed both these problems. Each fan comes with a laser cut aluminium frame which fits onto long bolts in place of the normal ones and the sensor is embedded into a special section of aluminium tube which along with two short hoses replaces the normal convoluted top hose. The Revotec came complete with a good set of instructions and all necessary wires, connectors, and even a set of cable ties to tidy up the wiring.

Inevitably my work involved in replacing the cooling system doesn’t stop there as while this was removed from the engine compartment I cleaned it up as much as possible. The radiator surround and expansion tank, I had previously fitted, were removed and painted with black Smoothrite and the water pump hub in yellow. The inner wings were cleaned, a few areas touched in and all polished. I replaced the lower radiator hose, crankcase breather and oil cooler grommets at the same time while I had easy access.

Everything was installed relatively smoothly and with no problems. I wired in the fan and controller loosely to make sure everything worked properly, before I committed to cutting the wires to size and fixing it as tidily as possible.

The MGB all fired up first time and amazingly there were no leaks from anywhere. The controller worked well and after allowing the engine to heat up and the fan cut in OK. It took a few cycles to set it at about the right operating temperature. A good road test in varied conditions also proved successful, still without leaking. The Revotec works really well generating a huge airflow which cools the radiator very quickly and cuts in and out smoothly. My only criticism of Revotec is that nowhere in the instructions did it say what ampage fuse was needed to the fan supply. A quick Google search found this on the Revotec website. So why on earth don’t they include it in the printed instructions?

In theory removing the engine driven fan should also release a few extra bhp but no-one ever said how much. But as the MGB was originally only 95 bhp, and presumably over the years this has dropped a bit, even only a few bhp could make a 5% difference although there wasn’t any noticeable difference during my road test.
