It is our pleasure to have been part of this World Record setting project for the F8x M3 / M4 S55 engine platform. Factory ECU tuned using bootmod3 by Halim@HCPerformance. Impressive numbers and certainly leaves us wondering what is next for the S55 engine platform and to see this setup take on the 1/4 and 1/2 mile!

It's with great pleasure that we at Global Motoring Group share the latest results of our KRATOS KRAS55Bi Turbo System.
As many of you may know, within a week of completing an engine build on one of our developmental S55's we were able to put down preliminary dyno results of 975whp and 752wtq @ 35psi on pump E85. As the turbos clearly had much more left in them combined with the fact that the 35psi run is very close to the limit of the factory map sensor, we decided to move forward with installing a 4 bar map sensor that would enable us to dial in additional boost. Moreover, being that the KRAS55 line of turbo systems will begin their public release this month, we wanted to update those who have been following our recent developments.
We reached out to Burger Motorsports as they had a Bosch 4 bar sensor upgrade kit that would work for the application. Unfortunately, their kit was not made for S55's, but with the help of Terry & Payam they were able to put a custom PnP harness together for us in only one day and promptly shipped it to us. Once installed, Halim@HCP rescaled the map sensor to prepare the car for further testing of the KRAS55Bi turbos. With the car dialed in on a HCP custom tune @ 41psi and Ignite E85 fuel (E83 Via Fuel-It Sensor) with an ambient temperature of 77°F our KRAS55Bi's produced the following results listed below.
