Last time I dynoed all motor - 649 RWHP. We have since done a little more head work and expect around 660 RWHP. :nod:
Anthony,


You Sir, Have my Respect!! I've always believed that the Viper V-10 was more than capable of 600+ NA. I looked at Ford's V-10 that was hitting over 600+ with race gas and was in disbelief that they could hit the figure and Dodge Couldn't.

Thank you.

BTW, would you list what you've done? Hardened internals? Head work machining on the outflow? Manley and Oliver components?


Thanks,

Jay K.

BIG BREEZE... GREAT NUMBERS!FROM THE LOOKS OF THE DYNO SHEET IT APPEARS U ARE RUNNING A STOCK COMPUTER AND MAYBE JUST A VERY SMALL BIT ON THE RICH SIDE.IF THAT IS THE CASE YOU HAVE A FEW MORE HORSES TO BE GAINED. WHAT IS YOUR A/F RATIO? :rofl:

that's awesome work...congrats...only thing I dont understand is why someone would wanna do that when they could spend about $15k more and get 1000rwhp? $15k and 400 more rwhp sounds like a good idea to me :thumbs2:
