  4. ESS G3 Supercharger is available?!?

    Kits were officially announced October 16th. Not sure where the 6 month timeline came from. However, I can say that I just got word today that the final parts are headed to powder coat tomorrow.
  5. ESS S650 runs 8’s in the quarter mile!

    This car has a Circle D converter in it so it will change the driving characteristics. Still drives very nicely. With the stock converter it will drive and behave 100% like stock
  6. ESS S650 runs 8’s in the quarter mile!

    You’re right! My bad! I just realized I didn’t attach the videos..
  7. ESS S650 runs 8’s in the quarter mile!

    On its VERY FIRST and only full 1/4 mile pass we managed to run 8.90 @155.79 MPH with only 16.9 PSI of boost! This is the quickest and fastest centri powered S650 on the planet. This is still a base file and only shifting at 7600 RPM. We are just barely scratching the surface of what this setup...
  8. ESS Centrifugal Superchargers ETA?

    With all due respect.. ESS was last to market in S550 and is currently outselling every other option by a mile. First to market is not a priority. Tuning was never available so selling kits and getting cars running on the factory ECU tune just to create fake hype was not the move. Developing...
  9. ESS Centrifugal Superchargers ETA?

    A few of the pre-order kits are starting to ship already. You will start seeing them around any day now. I would email sales and see if they will get you on the order list.
  10. ESS G3 Supercharger is available?!?

    I own that car, it’s not a mistake. If you look carefully the 125mm pulley is on 91 octane and the 120 pulley is 93. That’s why the difference in power. More boost and more ignition timing
  11. Dark Horse break in period?

    I think a lot of people take the break in too seriously. Most of them are not mechanically inclined and don’t work on cars or build engines/transmissions. Vary the engine RPM, seat the rings quickly, give the clutch/trans a few miles before you abuse them too much. And good to go. 1k miles is...
  12. First production ESS S650 kit has arrived!

    Awesome! More than welcome to come check it out anytime. @boostbarnracing on instagram or look us up on google. Shop is in Tempe next to Tempe marketplace. 3rd party tuning is used.
  13. First production ESS S650 kit has arrived!

    Most people won’t push a car this hard and especially not on a stock engine. This was just to show what it’s capable of in a race application. But throughout our testing it would make 30-50 less with the inlet and filter on it.
  14. First production ESS S650 kit has arrived!

    E85 and peak of 20-22 PSI
  15. First production ESS S650 kit has arrived!

  16. ESS S650 makes 1106 WHP on the dyno!

    The latest stage of our development S650 hit the dyno and put down some serious power! Mods are: ESS G3R supercharger system (8rib) Fore fuel system Headers Factory sealed engine. Stock OPG @boostbarnracing
  17. First production ESS S650 kit has arrived!

    It did hold right around 55-60 toward the end of the pull if memory serves me correctly. Never got low enough to require a BAP. However, a BAP is still probably a good idea.
  18. First production ESS S650 kit has arrived!

    No BAP on that car. Stock fuel pump and 55lb injectors
  19. First production ESS S650 kit has arrived!

    Tuning is always required. Just swapped fuel injectors.
