Does anyone know where I can get some general road load data? There was a study I saw a while back of a guy that put WFTs on his car and drove around for 10,000 miles or so and posted the data, but I can't seem to find it.

I've tried to figure this out, but have come up with nothing so far, so maybe someone here can help me.
The fuel in our vehicle is turning red, and we can't figure out why. We put new fresh gas in our gas tank, and it's fine, and if we sample the gas from the tank, it's normal. But if it...
I've been going through the CFR to check the regulations that will apply to the vehicle my company is building, and a significant part of that is 571.208 (i.e. Occupant Crash Protection). I have been endlessly confused to the point of despair by Section 4.7 of this standard however, which...
I'm getting set up to run brake lines for the prototype vehicle my company is building, but I have a few questions. We're taking a fairly standard approach and using hard line from the master cylinders out towards the wheels, and then using flex line from the body to the wheels. The issue I'm...

I'm trying to source parts for the fuel system of the vehicle we're building, and I'm having some trouble finding a source for the fuel filler neck/gas cap/door assembly. I found the goodyear fuel fill hose, which we could run between the gas cap and the fuel tank, but other than just buying a...

I'm trying to find more information about the EVAP system, and I'm having trouble. In addition to the exhaust system which I'm designing (which a number of you have helped me out on, thanks for that) I'm also doing the fuel system, and the engine we're using (Rotax 4 cylinder 4-stroke Aircraft...
As I mentioned in a previous thread, I'm in charge of designing the exhaust system for the vehicle my company is building. Are there any kits available that you can buy that make designing a custom header/exhaust system easier, or is it just a matter of going to home depot and buying a whole...
I was put in charge of designing the exhaust system for a vehicle my company is building, and I was reviewing the Code of Federal Regulations as it pertains to vehicles, and under the section for exhaust systems it says:
"No part of the exhaust system shall leak or discharge at a point forward...
I'm a vehicle design engineer, and I'm trying to do some weld calculations for some suspension components that need to be TIG welded. Unfortunately, the only calculations I can find in my test books are for arc welding. Are there any books/resources I can find calculations for TIG welding, or...
I work at a company designing our own lightweight vehicle, and we're planning on having a double wishbone suspension with pullrod-actuated inboard shocks for the front suspension. The vehicle is all composite, and due to the lack of space in the engine compartment, we were planning on mounting...
