SEMA 2004, we took over 800 pictures
in 4 days
Mopar, Superchips and Paxton, we sort threw the
I was surprised to see older folks in the
Mopar booth this year. Last year the punks were in puberty and could
care less about the Ram Hemi. Still not much coming from Mopar for Hemi
Trucks and SUV's. Even the Shaker hood on the lime green Daytona Ram in
the booth had a shaker functional ram air mounted to the engine, but
this shaker is being built for the 300 and magnum not the Ram.
Same thing with the dress up kits for the
engine, I found at SEMA are being produced to offer on the Hemi cars for
Mopar. No one at the Mopar booth could explain
to me why the Dodge Ram Hemi, which started the latest craze for Hemi
enthusiast, was being left by the side of the road as Dodge and Mopar
act like the cars are the only ones with Hemi's. Colorado
Custom did have their dress up kit for the Ram Hemi on display. One is
being sent to MrHemi for review.
This is where I need MrHemi here with the
voice of reason as I tend to get upset if can't find explanations that
make sense. A DC engineer in the Mopar booth, Eric Vickerman did answer
questions for me. He said the 03 Hemi has room for improvement with
engine controls and this might be why Superchips was able to modify it.
But he claims the 04 and 05 Hemi were built at their maximum
ability and couldn't be modified or at least not more than 5 horsepower.
( Do we believe this). Vickerman told me the 6.1L Hemi won't come
to Ram trucks as it's a SRT engine and will only be used on those
vehicles (Magnum, 300). I asked him if there were any improvements
planed on the Hemi 545RFE automatic to improve the power in 4th gear and
he said no. Vickerman stated that the transmission was controlled by
engine and was what it was. (Made no since to me as 4th shouldn't be an
overdrive in a gas engine when 5th is also overdrive). So hopefully
the aftermarket manufactures will continue to work on products for us to
fill in the many gaps left by DC.
Next I asked Superchips vice-president of
engineering, Steve Madole if what Mopar said about 04/05 Hemi's not
having room for improving engine performance was true. Madole stated
that there was room for better managing the engine controls on the 04.
Superchips hasn't finished the 04 programmer and are also working on the
4.7L as it is easier to modify. And we know OEM's purposely make it hard
to modify engine controls, so it does take a lot of time. Superchips
hasn't finished the new common rail Dodge Cummins diesel programmer
either, and it came out in 2003. It's looking like next spring before
we see a 04 Hemi Superchips programmer.
I talked to Roush and Paxton about their
plans for a Hemi blower. Roush's program manager, Todd Andrews, said
they are looking at a blower for the Hemi but no definite date. Paxton
had more to say, they do make a Mopar blower as part of a tuner kit but
don't recommend it for the Hemi. The reason I was given was the
pistons. The Hemi top ring land is only 3 mm from the piston top and
according to Paxton, 3 or 4 psi of boost could break the piston land lip
off. They went on to say that a good aftermarket piston would easily
handle 14 psi of boost from their blower.
