Is E85 better for Turbo?
The good stuff about E85 with turbo/SC cars is that the high-alcohol fuel has a higher octane (knock-resistance) and a cooling effect, both allowing you to run more boost and/or timing than on 92 octane. Running higher boost is not the same as higher flow, and your exhaust energy will still be roughly the same.
Does E85 reduce turbo lag?
The E85 did help with the turbo lag but didnt fix the lag completely.
Does E85 increase HP?
After jetting the blower carbs for E85, the power output jumped to 700.1 hp and 646 lb-ft of torque. In addition to the power gains, the E85 dropped the inlet air temps by over 70 degrees, from 166 degrees to 92 degrees!
Is E85 good for high compression motors?
Plus, E85 reduces inlet air temperatures which improves power by cooling the air entering the cylinder. Cooler air is denser, which adds power. There will be significant tuning changes necessary when using E85 instead of gasoline, but high-compression engines can especially benefit from E85.
Does E85 burn quicker?
The drop in fuel economy is because ethanol has lower energy content per gallon than gasoline. E85 also burns faster than regular gasoline because it vaporizes faster. So your engine may eat through E85 faster than regular gasoline.
Which is better E85 or 87?
E85 has an octane rating higher than that of regular gasoline’s typical rating of 87, or premium gasoline’s 91-93. This allows it to be used in higher-compression engines, which tend to produce more power per unit of displacement than their gasoline counterparts.
Is 98 or E85 better?
Even at low power levels, E85 can also be a much safer fuel than normal pump gas. Aside from cooling the incoming air charge, E85 will reduce hotspots in the combustion chamber that can trigger preignition with regular gas.
What’s the difference between gasoline and E85 fuel?
Unlike gasoline, it burns differently and at different rates. The quantities needed are different: more E85 is needed than gasoline, typically 20- to 35-percent more. E85 is the designation for an ethanol-blended fuel where ethanol makes up 85-percent of the content, and gasoline 15-percent.
Which is cheaper pump gas or E85 for boosted street engines?
Even winter blend E51 will be about 100 octane after being cut with low octane gasoline at the refinery. That still beats pump gas by a mile on octane. E85 is usually cheaper by the gallon, but that is an illusion as it contains less energy than a gallon of gasoline.
What are the benefits of using E85 in a boosted car?
This primary usage of E85 does not take advantage of any of its potential performance advantages. Key benefits of E85 wasted on flex-fuel cars are: high oxygen content, evaporative cooling, higher octane and lower exhaust gas temperatures (EGTs). All of these can be exploited when looking at building a boosted car.
Can you run pure ethanol in an E85 engine?
Provided that the fuel injectors can maintain adequate flow at maximum duty cycle, using E85 in a turbocharged engine can allow the driver or computer to turn up the boost for serious gains in power. At that rate, you might as well run pure ethanol for a huge increase in boost and power potential.
