I can give you proof with video next season. Hell maybe this season if my tuner gets out to the quarter again. The car has radio and full interior. Ran a 11.7 last year with about 350. Dynod at 480whp couple weeks ago and that was with boost falling off up top (is being addressed).
Some quick links I found.
11.2 - del sol (stock internal motor)

654hp with AC daily driven

Hell if you want get on honda-tech search either jeff evans (boostedhybrid) or search mase and almost all will be 500+hp cars.
I would search for more but its not worth my time. those were at the top of the board while I was looking around.
Oh and I love the excuse that they are "$50,000" cars. Who the **** cares how much it costs? I didnt know money was at issue here? Just sounds like another lame excuse. Adn 50 grand is a little high. Im sure they have spent alot but not that much.
