    • SeriousHP Houston Dodge Challenger Hellcat E85 conversion dyno results and comparison to 93 octane

      So how big of a difference is higher octane ethanol making over pump gas with a tune on the Hemi Hellcat twin screw supercharged V8? A big difference. A massive difference. SeriousHP in Houston, Texas got another 81 horsepower at the wheels and an additional 70 lb-ft of torque at the wheels.


      All from E85 and upgraded injectors along with a Kenne-Bell Boost A Pump. The thing is, this is not even as far as it could go. The tuning is being done through the HP Tuners software and the software does not yet have complete control over the transmission so torque is being limited on shifts. They want to rev it about a further as well.

      These are very large gains just a month after SeriousHP Houston posted tune only results on pump gas. The gains here are somewhat exaggerated though as tune only SeriousHP hit 706 RWHP previously.

      With the tuning software offering better TCM support and with a new pulley for higher boost added we should see Hellcats easily up over 800 wheel horsepower with just the basic bolt ons.

      Incredible.

        It needs that extra power because it weighs more than my house

        Great results and shows the real power of using E85

        Stock pulley still... don't think they have turned the boost up manually yet.
