Hello,

I am new here and don't know if this is appropriate so let me know. I am not an engineer and no formal training other than a few Physics classes in college many years ago. I do however have a high mechanical aptitude and have always done some personalization of machines. Eg. I put a lawn mower engine on my bicycle at age 10. etc.

I am now attempting to modify a 1958 Corvette Rochester Ramjet fuel injection to run on a different engine. The item I need help with is the means of powering the high pressure pump. Originally it it mechanically driven via a flex cable attached to a special distributor.

Since the engine is not going to exceed 6000 RPM and the cam speed is 1/2 the speed of the crankshaft, I will need to find a suitable 12VDC motor that is capable of up to 3000 RPM.

I do not know how much torque/power it will take to turn the gear pump that it will attach to but a greater concern it that it will operate in an environment that consistently exceeds 200° F. It does not need to be variable speed as the flow is controlled by a mechanical bypass value in the fuel reservoir.

I would appreciate any help on pointing me in the right direction, who I might talk to etc.
Thanks for your time.

Hello Dan,

Welcome to the forum! It's great to see someone with a passion for personalization and mechanical aptitude. Your project sounds very interesting and challenging. I would be happy to offer some guidance on the high pressure pump for your modified Corvette fuel injection system.

Firstly, have you considered using a brushless DC motor for your high pressure pump? They are commonly used in automotive applications and can provide high torque and speed capabilities. They are also more efficient and reliable in high temperature environments compared to brushed DC motors. You can find brushless DC motors capable of up to 3000 RPM and 12VDC power supply online or at local automotive supply stores.

Another option would be to use a small gasoline or diesel engine to power the pump. This would require some modifications to your setup, but it may be a more practical solution if you are unable to find a suitable electric motor.

I would also recommend consulting with a mechanical engineer or automotive specialist to ensure the pump and motor you choose will be able to handle the specific demands of your modified fuel injection system. They may also be able to provide additional guidance and resources for your project.

Best of luck and happy modifying!


 

1. What is conversion?

Conversion refers to the process of changing one unit of measurement to another. It is used to convert a quantity expressed in one unit to an equivalent quantity expressed in a different unit. For example, converting meters to feet or Celsius to Fahrenheit.

2. Why do I need to know how to convert units?

Knowing how to convert units is important in order to make accurate and meaningful comparisons between measurements. It is also necessary when working with data or conducting experiments from different sources that use different units of measurement.

3. How do I convert units?

The conversion process involves using conversion factors, which are ratios that relate the two units of measurement. To convert from one unit to another, multiply the given measurement by the appropriate conversion factor. It is important to pay attention to the units and make sure they cancel out correctly.

4. What are some common conversion factors?

Some common conversion factors include: 1 inch = 2.54 centimeters, 1 pound = 0.454 kilograms, 1 liter = 1000 milliliters, and 1 mile = 1.609 kilometers. It is helpful to have a conversion chart or calculator to easily access these conversion factors.

5. Can you convert between different types of units?

Yes, it is possible to convert between different types of units as long as there is a conversion factor that relates the two units. For example, you can convert from meters to feet, but you cannot convert from meters to liters since they are measuring different quantities.
