I’m building a 4-cylinder, air-cooled, twin-plug, ~1.9 liter autocross engine. The cylinders are
Nikasill with JE Pistons. The pistons will be TB coated on the top and have anti-friction coatings on the
lands and skirts. The combustion chambers have been reworked to unshroud the valves
and...
I'm looking for a table or calculation that will allow me to determine the volume flow rate of an automotive gear-type oil pump. I'm guessing that I need gear pitch. diameter, length and pump RPM. Anything else?

Hi,
I'm looking for a source of 25 x 75 mm microscope slides with almost any thickness from 0.1 to 3mm. The material needs to be relatively tranparent and have high thermal conductivity. I would appreciate finding the manufacturer, vendor and part number, if possible.
Thanks,

Engine- Flat four, air cooled, was 1588cc - soon to be 1883cc, head/valve work, twin plug ignition, split-lobe cam, etc.
Service- Dedicated, lightweight autocross car.
Hoping to achieve 35-40% power increase but mostly a higher and wider torque band. I have been advised to cryo...

Hi all,
I've designed a composite anti-intrusion bar that will go into a race car. The part is in the shape of an 'I" beam with the web horizontal and the caps facing the door skin and interior. The dimensions are: Bar length = 41cm, Cap widths 25mm, Web height = 70mm. The proposed web...
Can anyone suggest the variety of steel types that might have been used by Volkswagen and Porsche (1955-1960) in the manufacture of forged front suspension trailing arms? I'm curious to know if there are several or only a few possibilities.
I realize that I could sacrafice a part and have an...
