Most 240 hp cars will dyno just over 200, GTPs are an example. To gain over 30 hp form CAI and exhaust is almost unheard of unless maybe if you have God Motor (LS1).

 

The difference between the Accord V6 and the GTP is that the GTP is supercharged. Basic bolt ons will net you a TON more gain from an engine that is FI'd over a high rpm strung out econo engine such as anything Honda produces.

I'd like to see the gains from an accord with basic bolt ons though.

 

So if he does make 240 fwhp from CAI and exhaust alone, then the Accord is indeed underrated?

 

One would think so
