I am trying to write some functions to calculate the velocity, acceleration, and jerk (change in acceleration) of some valve motion data.
The data is typically about 220 points
The x axis is evenly spaced with an increment of 1
The y axis is provided in a list of "position data"
I would like...
I have entered a gravity powered car race like soap box derby for adults. The size of the car is a maximum of 4 x 4 x 9 feet.
I would like to know what the lowest drag airfoil shape is that I can try to apply wherever possible.
The average speed will be about 40mph with max at about 60mph.
I...
I am considering building a gravity racer and I wonder if ot is better to have suspesion or not?
How would I determine the optimum weight?
Any suggestions for steering geometry parameters? Caster, Camber, trail, scub radius etc.

I am planning the construction of some rocker arms machined from steel plate. I am not a steel expert so the best guess I have is to use H11 or H13. Any better suggestions? Material price should be under $20/lb to keep it practical and something reasonably machinable with carbide.

Is anyone using Start Parts? If so, could you explain the concept you use? I am hearing some people calling a "Template Part" a "Start Part" and others say a "Start Part" is part of a structure used in modeling parts with geometry linking.

I am interested in modeling the shape of water that is pumped over curved surfaces to make a surfing wave. Something like Wave Loch.

Does anyone have experience with a software that is well suited to this type of work? I have high skill in CAD modeling but only...
I am designing a 4 barrel carburetor (similar to a Holley Dominator) and would appriciate some help from someone that knows about the design of air inlet shapes.
The engine vacuum at full speed open throttle = .5 hg water
The fixed parameters of the inlet horn are:
Length = 1.25 inches

Does anyone know why most carburetors mount the needle and seat in the upper half of the housing? I know the Q-Jet is an exception to this but I haven't found many others.

I am in need of a custom carburetor float, does anyone know someone that can product brass floats in small runs (about 1,000) in the USA?

I just finished a fun project making an intake manifold for spread port BB Chev.
I made some photos of the key steps and posted them on my web page, see the manifolds page.

I have decided that for this years non-profit-fun-project I will make a set of patterns to make a new engine block, and or cylinder head. My problem is that after considering the many possible configurations I have not been able to settle on one design.
The following is a list of configurations...
Here is my plan....Start with a large fortune, then make a large V-8 2 stroke for sportsman dragster racing.
The basic scheme is a supercharged piston port design with 4.840 bore spacing so I can use big block Chevrolet crank and rods.
The foggy areas for me at this point are port design...
I am interested in using CFD to visualize flow in cylinder head ports, manifolds and cooling passages.
I will use it to evaluate design alternatives that I currently model in 3D but test only physical models.
The application is drag racing engines.
At this point I am only concerend with...
Hi All,
I am trying to figure out the vacuum strength that is pulling fuel through a jet of a racing engine. The case is a drag raing big block chevrolet with 2 dominator carburetors.
I don't have a practical way to measure it on a running engine but I would be satified with a reasonable...
