Dyno Results from CAI/FMIC Upgrades

[eaboyle57]

Hey y'all, looking into upgrading to the Injen CAI and looking at intercoolers currently. The question I have is, how can you accurately assess performance improvement for airflow based modifications with a Dyno? The entire point is that the CAI is ushering colder air to the turbos at highway speeds. On a Dyno there isn't any air being pushed through the grill...is there? I just can't wrap my head around it.

Dynos only say so much. Also, people tend to get caught up in the little number in the corner on the dyno graph saying peak power, and pay no attention to the shape of the curve or the area under the curve, which is what actually makes a car faster. Some form of GPS-based device like a dragy that can measure distance over time accurately on a pull would be a more accurate and IMO useful method to see any increases in performance.

Some Dyno's have large fans that they point at the front of the car and turn on during the dyno testing to help simulate wind, but it will never give you a perfect assessment of how something like an intercooler would benefit you. I'd almost suggest getting a dragy and doing a before and after of 0-60 and 1/4mile times to see results from something like an intake and intercooler.

Dyno measures how big your ego is. Lol jk. Ran a draggy to assess the performance. You’ll see consistent results from your pulls when you upgrade your intercooler.

The better way to look at a Dyno is as a tool. It's used for tuning and comparing. It isn't going to mimick real world driving but can give you data that you compare with other runs.
The intakes will give you an increase in tq and ultimately horsepower; they are a restriction and you will gain power.
The intercooler won't make more power but it will keep the power consistent. On a hot day with the stock intercooler you will notice a pretty big loss in power if you do a few pulls. With an upgrade the pulls will feel the same
