# Does E85 require bigger injectors?

## Does E85 require bigger injectors?

It’s necessary to have such large injectors when using E85, because you must plan for about 30 percent more fuel, due to E85’s lower energy. This also means larger fuel pumps are required to provide the volume needed.

## Can you run E85 all the time?

Because ethanol attracts water it can create rust and seal breakage over time, and if E85 is left in the fuel tank for long periods it can attract more water vapor and potentially cause engine damage.

What is the highest compression ratio for E85?

That means that you could reasonably build a 14:1 compression ratio engine and run it on E85 and not expect problems with detonation. This also reinforces Rockett’s listing their E85 fuel as compatible with a normally-aspirated engine with up to 16:1 compression ratio.

How much HP will 60lb injectors support?

60′ will support 600+ rwhp with pump fuel…not the case with e85 at those levels!

### How much HP will 42lb injectors support?

Registered. 42lb’ers should be able to support close to 100hp a piece at 100% duty cycle, Your injectors must be dirty or something if they are maxing out at your power level.

### How to determine the size of an E85 injector?

Now that you have determined your base injector size you will need to determine the difference in size to run E85 Fuel. The way to do this is to do some simple math. You are going to use the multiplying factor of 1.47 to get your size. The 1.47 number represents the difference between the stoiciometric fuel ratio of gasoline and E85.

How to calculate the fuel flow per injector?

The following is a guideline equation for approximating fuel flow per injector based on estimates on engine Horsepower (HP) and Brake Specific Fuel Consumption (BSFC). Fuel Injector Calculator Flow Rate Conversion

Is there a fuel injector calculator for fueltech?

FuelTech makes the selection easier for all enthusiasts with its Fuel Injector Calculator. It is capable of recommending fuel injector sizing for naturally aspirated and turbo combinations that are run on gasoline, alcohol, or ethanol.

#### What’s the difference between the 1FZ F and Fe?

The 1FZ had only two variants available: the 1FZ-F and the 1FZ-FE. The only significant difference between the two was the inclusion of electronic fuel injection on the 1FZ-FE, whereas the 1FZ-F used a carburetor. [2]
