Higher Octane is critical to achieving the maximum safety, consistency, and power from your supercharged ISF. Our e85 tune achieved a 40hp increase, which translates to about 570whp on our DynoJet, or about 670hp at the crank (see Dyno chart in the photo catalog for this product).
After experimenting with various e85 ratios we determined that 45% e85 content is ideal. Running full e85 results in loss in power compared to 45% e85, as well as much higher fuel consumption. Our e85 upgrade kit comes complete with updated tune, Innovate Motorsports e85 gauge, and upgraded in-tank fuel pump for extra capacity.
