Prospeed Evo BR 2.0LR 6766
Greetings
For past few years my setup was 2.2 stroker engine with NDT04Z billet turbo. Not a bad car, however best ET stopped at 9.6, therefore this year I decided to change for a high rev motor with something different on turbo side. Selected the following setup:
- BR 2.0 LR engine
- BR FF header
- PTE 6766 turbo
etc.
The first dyno was pretty good, unfortunately at 42 psi boost heavy misfiring started, therefore had to stop at this (these are European measurements, crank HP and NM torque).

Then changed the plugs and got around 100hp more on street tune. Last weekend there was an opening race, unfortunately only 1/8 mile distance. Track is on a racing circuit, no drag prep, no traction. With heavy spinning and only 1.62 at 60ft the result was pretty ok - 6.14@122mph. Main thing, the car was really working as a clock, shifting at 10krpm with no problem, nice drive. Now cannot wait until the next race which will be 1/4mile. Some more pics:

Mid 9s sec car if you use the 1/8 to 1/4 calculator. Nice job

Finally got to the 1/4 mile track. Some undiscovered demons did not allow more than 38psi boost although target was 50. Still made a number of good runs in 9.4s/9.5s with the best 9.451 at 150mph. 1.538 60ft. Hope to improve after fixing the boost issue.
