    I had my 04 srt on the Dyno today and my results are rwhp 443.89 rwt 465.42 just running Corsa and K&N cold air. Anyone have any thoughts on these numbers? It seems that it is running a bit rich at 11.16 air/fuel mix so there is some work to be done there. Seems about right with the deduction of 15% from 510 hp Comments Please.......

    I have the same mods & my #'s are in my sig, although FWIW the dyno shop forewarned that their dyno reads a bit low, but the range is about right, seems like yours would be a little low, but could just be how the dyno calc's the #'s. Did you happen to do a baseline before mods?

    No I did not base line first. I wish I had but no dyno in town then. Just found this guy last week from Dodge dealer. he told me I could get about 20 more hp if I leaned it out to about 13 a/F. Meaning a flash I know there is more to get but, I don't want to go overboard if that was the case i would just go to paxton. thanks for your input. I guess these dynos are all a bit different.

    I ran mine on the DC Performance dyno about 3 months ago and pulled 454rwhp and 474rwtq with just a K&N filter on it. I have heard the engine in the 04s pull pretty hard. I had higher numbers than quiet a few others that were a lot more heavily modified than mine. To say the least I was very happy with my numbers.

    Get a reflash from DC Performance. I had same mods but removed cats and after dc flash I jumped up about 20 rwhp peak and gained about 40 in the midrange. Mim range.ne dipped down low 11's and into 10's, very rich, after i was at about 12.8-13.1 across the rp

    First, are you running the 3" Corsa Track ore the 2.5" version that hooks up to the stock cats? The XP985 plugs might also add a couple of hp.

    Since none of the cars were run on the same dyno, it could be variation in the dynos ... I know a tuner that says most of the stock SRTs that he's tested run between 435-440 rwhp bone stock -- on his dyno.

    The Corsa track is the same just the inlet has the change I had the Rt cast and the 3" but I couldn't hear myself think, not that I do a lot of that. Jon B sent me a reducer so I could go back to my stock cats. The fitting was time consuming but the sound was great when I finished. I spoke with Dan at DC and sent him my Dyno sheet. He told me that most stock Vipers come in about 425 RWHP. I will see what he thinks and let you know how the reflash works out. I just don't get the numbers that get posted here when I compare it to mine Mike was getting 508 RWHP with just some minor mods. I know dynos are not all equal but a 510 hp engine getting 508 at the wheels very nice. As for plugs I just installed Autolite Fusion plugs pricy but they seem to perk it up some.

    My 508 rwhp, is still what I consider minor mods, but I may have more then you think.
    I have M&M Headers, NO cats(Big power difference on dyno) Corsa exhaust, green filters, UD pulley, X-metal TB, XP985 plugs, DC Performance Flash. The power has slowly, creeped up, from mid 400's , I wathced it hit 468, 487,496 and now 508 rwhp. Every car is different and every dyno is different, but as you add the basic mods i listed, you will definately see power gains.

    That car must roar... cool What is a UD pully? I was thinking of the TB did you feel any difference? I am going to get it flashed for sure thats the main thing I think. There is a lot to gain there. no cats I guess no smog certificate. Were you in Danville in August?

    Aftermarket Underdrive crank pulley is smaller then stock and a little lighter. Reqiures new belt. 20 minute install, better throttle response, quicker revving in my opinion. I did that and TB at same time and dyno'd I beleive a extra 7 rwhp. Then headers added about 12 rwhp.

    And I have been in Danville a few times, but I wasnt at Hot August nights. Im mostly always roaming San Jose area.:drive:
