Piers head/cam & dyno egt

[Cousin Billy]

Dyno results,



Put my old 12 valve on the dyno at the Scheid event this past weekend and had some interesting comments.

When the dyno operator (Brian) ran my truck on it's second run, he commented to me afterwards that the egt's never got over 1450 on a 25 second run. The first run was with a #10 plate slid full forward. . 437hp/1129tq. The second run was with a B&M Diesel Performance custom ground plate. . 461hp/1092tq.



My point is this, anybody with a #10 plate or more knows how hot/ how quick this combo is even with an hx40 and good intake air flow.



With the PDR ported head and cam, the egt problems are MUCH more manageable.



I was very happy with the results, especially since the ONLY pump modifications I have are the plate and 4000 spring kit.

The timing is only at 15. 5 degrees.



Plenty of room left for more fuel and the ability to use it





Piers cam and ported head ROCKS on a 163,000 mile 12 valve!!!

Billy:



Congratulations on your great dyno numbers at the

Scheid Rally! Your numbers show how good Piers'

cam is, but we all already know what a knowledgable,

great guy Piers is and how well all his stuff works!

As I told you, I knew your truck would run well!

I am glad I was there to see you run!



Again, congratulations to you!!

Smoke?

Todd,



About the smoke. Like most trucks, until the boost is at least in the teens, there is smoke when you really stand on the loud pedal. BUT, once the boost catches up with the fuel the smoke goes to a dark gray, then light gray and when wound out tight in third, fourth and fifth gears you only see a haze behind you.

When you stand on it in the lower gears, it belches out plenty of thick black smoke we all have come to know and love (sometimes)

JohnP rode in my truck at the grand opening of Black Mountain Diesel and seemed amazed at the lack of smoke and I know he was impressed with the low egt's

When a man that dynoed 508hp last year told me he thought my truck felt pretty strong, I was impressed too !!



Like I said before, my pump only has a plate and 4k springs.

I'll let you know what happens when I really get serious about adding fuel!!
