We've been receiving quite a few inquiries about Race MAF gains in comparison to the Street MAF housing so we decided to do another back-to-back test for you guys.
This car was equipped with our Cobra CAI, downpipe, front pipe and @KTuner 23 PSI 93 Octane basemap for testing.
We performed 3 consecutive dyno pulls with the Street MAF housing starting at 175 degree coolant temps to around 180 degrees. The car put down similar consistent numbers within a 3 horsepower and 4 ft/lb tq window.
We performed 3 consecutive dyno pulls with the Race MAF housing using KTuner's Race MAF basemap starting at 175 degree coolant temps to around 180 degrees. The car put down similar consistent numbers within a 1 horsepower and 5 ft/lb tq window.
We used "Run 4" as an average comparison due to identical run conditions. The Race MAF provide a 4-5 hp and 2 ft/lb tq gain at peak and 10hp/10tq gains throughout the midrange over-top of the Street MAF. Another thing to note is the fact that knock control continued to decrease with the Race MAF housing. We started the runs at .65 knock control and continued improve to .45.
In case anyone was unaware, KTuner now offers safe and effective Race MAF housing-specific basemaps for our cold air and short ram intake systems. The Race MAF housing provides nice little gains up top and very notable gains throughout the midrange.
