Yeah, I cant beleive those #'s on that Danger Mouse. I dynoed mine when I got it done about 6 months ago. I ended up putting down 275 rwhp and 280 rwtq. I was disappointed. The good thing was that the A/F was a horrible 10.0 across the board. The dyno dude told me I had alot more in it once the get the A/F in the 13 to 13.5 range at WOT. This was also with the 750 vac sec Holley 3310. Now I have the 650 DP and also have added a windage tray. I am hoping for 300rwhp once it gets sorted out . Also may install a carb spacer later as well.
