I don’t see those numbers happening on just e40.It should make around 660-675whp on E40 with a stock fuel system depending on HPFP limits.
But if you upgrade the LPFP and install port injection you'll easily make 750whp on E40 with the 6769
Appreciate the feedback! I currently daily my Supra although I have a few other cars available that I have been contemplating driving and leaving the Supra in the garage. It’s always so hard when I’m about to leave the house for the office though ? my morning commute is 20-30 minutes on the highway, so I’m hoping the bigger turbo will be livable. Looking to utilize the 6769 to its full potential, but will have to wait for built transmission until after my wedding next year haha this year I’ll be installing the turbo, full INGS kit, Verus wing, and call it a day.Ok I've driven 800 miles on my UltraFlow X turbo so far and it kicks in at 4000-4200rpm, the stock turbo used to kick in at 3500rpm, so the 6769 will spool in at 4700rpm at an educated guess. It's probably not the most street friendly drivable turbo, hence why i went a little smaller and took the X, because my power goal was 600-630 and still have a nice daily car.
Sorry to put a dampener on your choice but maybe you'll love the anticipation of the boost coming in later.
