Added 3 of timing all around, didnt add any HP... acutally lost a bit of TQ, but my powerband starts earliers and finishes later now. It also made my AF Flatter which was pretty nice... :) was jumping around from 13.2 - 13.7 but now its 13.4~ pretty flat. Ill get some dyno graph pics up laters.

97degrees in the shop/29.~ baro

Are your absolute heads 5.3 and did you have any clearance problems with that cam?

Thanks

oh i remeber your car, you had alot of problems with it. try to post up that dyno sheet asap, did you take that pos spintech muffler off yet? loose the cats? is the graph still flatlining at the top of the rpm band.
hopefully you got it all together

You added 3*'s??? Can't believe you didn't have clearence problems. I was advised not to advance with this cam. You should be a little over 450 on a dyno jet. Sounds like your right in line with what you are supposed to be making. Hope mine gets here soon. :p

they were 5.7l heads, milled .030 and I have valve reliefs... i dont know if its corrected or not to be honest. Doesnt say anywhere on this dyno sheet. Just relaying the weather reading on the computer screen for the mustang dyno program.

Everything was the same as my last run on the dyno jet Mike. Still through the mufflex no cats. 27lb psi tires. M6. Was just seeing if this dyno closer to my house was reading the same as the dyno jet 1.5hrs away... looks to be the same to me. Except ATAP was reading 68xx rpms and this graph shows 64xx at the end of the run

Got an E- WP to throw on was just getting a base line before I did some changes. Also changing the mufflex to a Hooker Catback. See what changes I get. doing it all in steps.

Are you saying you got about the same numbers on a Dyno Jet and a Mustang?

J, Congrats on the nice numbers buddy, you fix the loose rocker? You know you could just add a cut out and keep the Spintech to see if you really lose much before you swap out...

mustang dyno is 5% lower than a dyno jet, i would say you would have pulled 435 on the dyno jet
Add the cut out

ERR no...if you take an untuned stang dyno..it will be EXACLTY 15% less then a dynojet...but some people tweak their dyno's for better results..

i just talked to him...that dyno has been tuned to put out dynojet #'s...its still not running right yet...oil compression issues, etc..

He is talking about 3* of timing not cam advance.
