I'm trying to come up with a form to help me track problems with new vehicles. I'm not concerned with issues that are caused with customer damage, A/M accessories, etc. But i would like to track issues related to pattern failures of components, poor design, engineering issues, etc. The form...
I am familiar with helmholtz resonators in an engines air intake plumbing but can anybody point me to a online reference of how they work and the theory behind helmholtz? I imagine them working sort of like a capacitor, absorbing the pressure spikes in the intake system, but i have also seen...
Most of you have probably seen the aftermarket steel braces that bolt to the top of the strut towers on import cars. This is supposed to stiffen the chassis for better cornering. A lot of cars come with them now straight from the factory. I was just curious, how much do they really help on a...
Can anyone recommend any good auto engineering books that aren't too dry, but cover all the different systems and parts used today, how they work, how their engineered etc. The book i'm reading right now is Advanced Vehicle Technology by Heinz Heisler (sp?). Lots of good info, some of it is...
What is the best way to prevent deterioration and dry rotting or suspension bushings, especially in areas of the country exposed to road salt 4 months a year? I like to spray suspension parts and fasteners with grease every couple oil changes to prevent rust and to make it easier to align the...
I have a head with a damaged valve guide, there is a gouge near the top part of the guide (on the interior surface where the valve rides), the guides are not replaceable. The valve seems to move smoothly in the guide, it doesn't look like it would scratch the valve stem. Is the head still...
Most of you probably know that the first thing people do to try and increase there cars horsepower is to remove the cat. I have been told by many good sources that since the mid 80's we've been using monolithic cats that are not very restrictive, and removing them will NOT increase performance...
A store around here sells "racing wax," guaranteed to make your car go faster by reducing drag. My question is, would this stuff really make a difference on a vehicle traveling below a couple hundred miles an hour? I can't imagine the the paint finishes on new vehicles are rough enough...
I have heard that if you move the intake air temp sensor from it's normal spot (usually on the intake manifold) to a cooler location like the air cleaner, it will give you more power and better throttle response. Apparently because the air in the air cleaner is 40-50 degrees cooler than in the...
What are the equations to calculate the following?
Say you have an unlimited water supply flowing through a 20 foot diameter pipe. This pipe has a 10 degree downward slope from the water source. This water pipe is feeding a 7 foot diameter pipe with a 20 degree slope.
How would i calculate...
