Hamilton Cams Bigstick (181 / 210) Camshaft for 5.9L Cummins
How does Hamiltons 181 / 210 cam compare to the competitions
cam?
The following is the results of side
by side dyno runs with different cams:
I
have never done any dyno test back to back with competitor’s cams and mine. I have always just focused on our cams not
what others were doing. In the past I have called out a few individuals that have made some very negative comments about our
products but I have never known why they wouldn't just do a dyno run against my cam. Today I found out why.
I needed some data for an article that was being written. I asked
a few cam manufacturers to join in and maybe get some free press, none wanted in. I asked Aturo Ruiz of Buda, Texas if he
would allow me to install a few cams in his truck for testing. He was very gracious in allowing me to have his truck for two
days. We did 6-8 runs with each cam and picked the highest of each day for the comparisons. NOTHING
else was changed the weather was the same, same driver, same smarty levels.
Some people talk about certain brands making more power than another cam, but I have never
seen two cams run back to back on the same truck.
The setup:
h2, .010 lash int.,
.020" lash exh. Installed straight up with supplied key
181/210 lash int .010", .015” lash exh. Installed
straight up
Truck 2006 2500 4wd
Turbo S366 with 1.1 A/RExternal 38mm gate
Injectors 120 HP
110# springs
Hamilton pushrods
ZZ head
Smarty tnt
TS
pressure box
On the first runs the TS was at 25% the 181/210 peaked at 23hp more than the H2, and 167 more ft/lbs.
But at 2500rpm the 181/210 made an additional 225 hp and 500ftlbs
more due to the much earlier spoolup.
On the second set of runs the TS was set at 50%. With the H2 the truck lost
4 and dropped to 676hp. The 181/210 picked up 28hp to make 731hp.
