FWIW, I'm told that Kenny Brown's tech didn't hook up the ignition sensor properly. The 284/259 rwhp numbers from the DynoJet chassis dyno are probably NOT accurate. Will re-dyno during the summer months @ Rx7 Store's Mustang Dyno to look at how much rwhp loss there is with warmer ambient temps and air intake temps.

 

Yea something is wrong. You shouldnt lose that much HP even from hotter temps. Were you plotting A/F ratios on those runs?

Jason,

No AFRs were taken. I was merely guessing @ what the Power FC was reading since there was no data acquition at all. Kenny Brown is a low-tech Mustang tuner guy www.kennybrown.com. Changing to a smaller blower pulley to increase supercharger boost on a 2003 Cobra is about as high tech as they get LOL.

Actually, I will be passing through Columbus OH, 30 May. I will be @ Mid Ohio 31 May/1 June instructing for a TracQuest/Rennlist Drivers Ed. www.tracquest.com

How about we set up an appointment for me to have my car fine-tuned on the Mustang Dyno for the ambient air conditions...say around 12 noon or so, Sunday 30 May? I'm not due @ the Bellville Ramada Limited until 3 pm that day??

If you and Zavier have time, I'd love for you guys to stop by Mid Ohio some time during 31 May/1 June. As an instructor I can give rides all day long to passengers brave enough to ride with me LOL. I'd like for you and Z to experience first-hand the results of all the work you guys put in to my motor and mods setup.
