Check out the incredible shifting of our Transmission Tuning on the G80 M3 on a Big Single turbo, Pure built trans over 1000hp. Even with full weight, a full tank of fuel, and a passenger, it was only a tenth off its best time! 🤯The customer is thrilled with the improved shift speeds and driveability of their car! 😍
Sutphin Transmission Tuning can make a world of difference in your driving experience.
Stay tuned for personal best times coming soon. :)
B58 Strikes Again
This one isn’t your standard B58. This has a full Stage 3 Hybrid Setup
The result of this was 640WHP, using @mslperformance conversion factors we end up at 770BHP
Tuned via @mhd.tuning
Stage 3 Build includes:
- Complete Stock Unopened B58
- Daw 6769 @dynamicautowerx
- Dorch DS25 HPFP @dorch_engineering
- Osprey Front Mount Intake @osprey_performance
- Cooling Mist Port Methanol Kit @coolingmistuk
- DO88 Intel Manifold @do88performance
- Midnight Developments 3.5 inch Exhaust @midnightdevelopments
- HP70 Gearbox Swap / @sutphintuning Gearbox Map
- @dcautoperformance for all mechanical work & fitting to the vehicle
- @vogue.automotive for supplying the vehicle
This has been an amazing project to work on, using the correct modifications we’ve ended up with a car making great power but also extremely drivable and consistent. It also shows again how good of a platform the B58 is as long as they are looked after. This car gets the oil and filter changed every 6 to 8 weeks and has had no issues over the past 10,000 miles while running this setup bar the original gearbox slipping.
The car has achieved an amazing 9.88 1/4 mile time while being on the original open diff and still being an all round great daily driver.
Next things to add will be Port Injection along with a LPFP upgrade, this will allow us to run without the port methanol if we choose too.
The build is coming along thanks to @urena.auto
Can’t wait to get the car dialed in and see what it can do! @tunedbyshoup will be on keys as per usual!
Big thank you to Raza and the team at @rkautowerks for the support and quick fix on a minor issue!
Along with Brian at @appliedtorquesolutions the transmission has been nothing short of awesome so far especially with the new @sutphintuning trans tune!
Big thanks to the team at @precisionraceworks as well getting me setup with the AFS split loop fuel system!
And lastly thank you @imesswithcars for answering any questions and helping with diag when I’ve needed it!
