Seems to be easily enough duplicated.


Most of the fastest CJs run the OEM PCM? Maybe I missed something somewhere but I'm pretty sure that is not what I am seeing on any of the Holbrook engines. How many cars are we talking about using the OEM PCM? I can't imagine running OEM, but then again I wouldn't use something like BS3 either when something as capable as the MoTeC ECUs and dashloggers are on the approved list. For me it was a no brainer to buy MoTeC. There's certainly no RPM limit problem there either.

We currently have 16 Cobra Jets that we are tuning and support tuning for using the factory PCM and some of them are the fastest of their kind. The only limitation we've had is RPM and through our own research have made great strides but have never had support from the current Ford Performance drag race manager in doing so.

How many RPM's are you running at top end? 10,500 or More?

With the factory PCM we can run up to the following max RPM...


2008-2012 5.4L CJ cars are 7,800 RPM max


2013-2014 5.0L CJ cars are 8,200 RPM max


2016 5.0L CJ is 8,500 RPM max

My prior comments were about the tube between the throttle body and MAF rather than the part you've pictured as I'm sure you know, just clearing that up for anyone else reading. Wasn't clear what you meant by air kit.


Fastest of their kind rather than just saying fastest was a good clarification you've made. Carson's car certainly is real fast at 9.33.



Just a suggestion Jim, there is something to be said for poking the bear. I've seen posts on here from you like "Charlie Bob eat me" also. That doesn't play well here. I've learned at times it works out better for me to type out my diatribe about something, then delete it without ever sending. I wouldn't think this thread is going to be helpful for you.
