We've had our Audi R8 V10 Plus back on the Dynojet this week, continuing development of our flex-fuel calibration using the DynoSpectrum DS1 platform.
We've been working with E50 and E70 ethanol blends, alongside testing a prototype intake from Infinity Designs, which has shown some promising results.
The car is still running the Akrapovič titanium slip-on exhaust with factory manifolds and catalytic converters retained.
𝗗𝘆𝗻𝗼 𝗥𝗲𝘀𝘂𝗹𝘁𝘀 📈
🔹 Stock ECU (Akrapovič): 544 WHP | 406 LB-FT
🔹 Stage 2 (99 RON): 548 WHP | 410 LB-FT
🔹 Stage 2 (E68): 576 WHP | 429 LB-FT
🔹 Stage 2 (E68 + Infinity Intake): 590 WHP | 437 LB-FT
All figures measured at the wheels.
As expected with a naturally aspirated V10, the gains on pump fuel are relatively modest at peak power, although there are improvements throughout the rev range.
Switching to E68 made a noticeable difference, taking us to 576 WHP with the standard intake.
Adding the Infinity Designs prototype intake increased that to 590 WHP, a further 14 WHP at peak, with improvements continuing through the upper rev range.
What's particularly interesting is the difference in the mid-range.
At 5,514 RPM, we've gone from 369 WHP and 352 LB-FT on the stock calibration to 424 WHP and 404 LB-FT with the full package.
That's an additional 55 WHP and 52 LB-FT at exactly the same RPM.
Overall, we're now 46 WHP up on our original baseline, with considerably more performance available throughout the rev range.
Not bad considering we're still running factory catalysts and a naturally aspirated engine!
We'll be continuing development with Infinity Designs on the intake, alongside further work on our DS1 flex-fuel calibration.
More to follow as we progress.
