So, for now our final dyno day’s results..after various issues with a persistent cylinder 6 misfire caused by what we believe is erroneous factors and the boost leak caused by the Indy not fitting the inter connector silicon hose between the two turbo outer pipes..here we are..

With our Mr.5 inlet mod and the final tune V13+ aka ‘spicy’ which is 21.5 psi boost tapering to 20.5 psi here we go…546 BHP and 738Nm

Just about spot on compared to TTE the turbo people’s demonstrated N54 test..we did it on less boost ..so pretty good

Approx 50% of the increase over the max of 502 on v6 with no air filter is due to the Mr.5 inlet mod and the rest with many iterations of tuning covering boost, ignition timing and VANOS settings..this number is with a stock Mahle filter in the main box and a Pipercross Lotus inspired foam cone c/f filter…enjoy!
