BBK CAI Dyno Numbers
I recently had my car dyno'ed on the same dyno, same dyno operator, same weather, same car, and the same mods. The only difference was the BBK CAI on the 2nd dyno.
Stock Airbox + K&N
~170whp
~195wtq
BBK CAI
~175whp
~200wtq
So, at the PEAK, I gained a modest 5whp/5wtq, but at 4500rpms, I gained 12whp/14wtq. I also gained between 6-12whp and 10-14wtq from 2000rpms up to the max gain at 4500. So, in my opinion, CAI is totally worth it. Sure, its no supercharger, but thats a significant gain for little money. I bought mine used for $100, but Ebay intakes are like 14 cents, so thats the cheapest way to go.
