R2C intake dyno'd ... ever?

jpit · 07-26-2011, 04:48 PM

I have the R2Cs but have never dynoed them by themselves. I have the Modshack vent mod and often monitor the air intake temp and it is usually about 8 degrees above ambient temp so the vent is doing its job. It is very hard to duplicate airflow on a dyno even with large capacity fans. When the G3 was originally tested by a well-respected tuner there was a significant difference in the power produced with the bumper cover off and when it was on. I am skeptical of dyno results on intakes because you cannot reproduce highway driving and the ecu is very tempermental with rising intake temps.

So are you saying that the R2C's in the real life have no gains? loss of power?

I don't disagree, but unfortunately there are only 2 real ways to figure out gains, dyno before and after pulls, and 1/4 mile trap speed and times before and after, both those methods have pros and cons.
