is there a web link to the boost figures that IMSA allowed the turbo cars to run at the test?........think I found it:
https://competitors.imsa.com/sites/d...vision_1_0.pdf
Acura 3.5L V6 = 1.769 BR......resultant capacity = 6.19L
Mazda 2.0L I4 = 2.661 BR......resultant capacity = 5.32L
Nissan 3.8L V6 = 1.832 BR......resultant capacity = 6.96L
So based on that it looks like Mazda over-achieved with a small capacity engine, and Nissan have a potentially very powerful engine.......the Acura is allowed to hold max boost for a very long time (4400-6000rpm), but the others are just allowed a single peak, 7150rpm for Mazda, and 6000rpm for Nissan
Dare I say Nissan and Acura may be holding back a bit.
