A quick google shows there's ways to calculate HP from MAF numbers.
On the dyno she spun 250rwhp at 188g/s. After lots of playing with Tuner Pro and Forscan shes now gulping 213g/s. Looks like its time to go back to the dyno to confirm things.
But I'm happy to know its an indication we're heading in the right direction

Quarterhorse does a hp and torque estimation from airflow numbers. But in my experience it probably reads a bit high. It estimated my 220rwkw NL as 309 kw and 503 nm. I know a high stalled BTR probably soaks up a fair bit of power but i doubt it would be that much.
