[DeTomaso] Air cleaner

[John Taphorn]

The poor dogbone!  It just can't get Jack's respect.

Jack, I need to have a little fun with you.

I swear, we have measured the dogbone's effectiveness on both an engine dyno 
and chassis dyno over the last five years and posted the results each time. 
We even tested it on a warmed over 377 and a monster 408 where any breathing 
compromises would have been exaggerated relative to a 351. The 408 gave away 
10HP compared to no aircleaner at all (Didn't have a round one to avail to 
measure loss), and the 377 actually made one more when compared to the round 
air cleaner. Heck, the air cleaner even weighs only 58% of what you 
perceive.  Thankfully, I am still young enough to single-handedly install 
the 7lb air cleaner w/o an assistant.  Although, perhaps it is time for you 
to hit the gym.  :^)

Honestly, every time we address your previous observations regarding the 
dogbone with these quantitative measurements, I assume the fog from your 
eyes has been lifted and your future posts might mention this perspective 
along with your other experiences.

You see Jack, you are wearing us out.  You are the POCA/PI Guardian and 
Master Mechanic who has the generous disposition and saintly patience to 
respond with clarity and detail to topics and questions served up to the 
list by newer participants who have not heard them beat to death five times 
before.  I have always admired this about you.  You are a treasure to this 
Forum!

However, when you don't illuminate others' research, that tempers your 
opinion, you force the rest of us to get off our butts and contribute to the 
list.  A few of us are getting tired of this.  Whether you like or not, we 
view your role to be the one with the encyclopedic knowledge and the final 
authority on things Pantera.  This means you have the responsibility to 
expose all the angles in your posts; yes, even those opposed to your 
opinion.  In this manner, folks like I can continue to sift through the 
Forum e-mails looking for something fresh, new and personally relevant, 
while you and Mike Drew carry all the heavy lifting for the newer members 
who surface well trodden topics.

Ashamed of myself in Houston
