chip for 2005 300C Hemi?

A friend of mine was just given (yes, GIVEN) a new 300C Hemi. I haven't
paid much attention to Chrysler since I sold my 300M, but he's asked me
if anyone produces a "chip" for the '05 hemi.

If anyone has a lead on non-vaporware companies with performance-tuned
chips for this car/engine, I'd appreciate hearing from you.

Personally, for normally aspirated engines, I always thought that chips
were rather useless, but my buddy insists that he wants to do this.

Any info would be greatly appreciated.

Cheers,

 

Yeah, because the 300C Hemi is *so* lacking in performance from the
factory.

Your buddy is an idiot in need of a clue.

 

Thanks for the completely unhelpful response. A simple "no" would have
sufficed.

What do you mean by normally aspirated? The term usually applies to a
carburated engine, nobody makes a carburated engine anymore except for
lawn mowers.

 

Actually, no. The term applies to engines that don't use forced
induction (turbo or supercharging).

Wow, 2 completely non-helpful responses. I'm on a roll.

Cheers,

C

My recommendation is to leave the car as it is. It's performance is top notch
already and why mess with voiding the manufacturers warranty by doing
unnecessary modifications?

 

That's my advice too, but it's not my car. So I agreed to help my
friend by asking some questions online. I drove it a couple of days ago
for the first time and thought it was *plenty* fast.

Cheers,

C

 

I prefer my "no"s to be fancy.

 

No, "Normally aspirated" is a term that does not refer in any way to the
fuel delivery system. It simply means there is no forced induction device
(supercharger or turbocharger).

 

The most helpful thing you can do for your friend is to pass along --
verbatim -- the responses you're (he's) getting.

 

I would recommend that instead of trying to add power to the engine, he
concentrates on reducing weight. Replace the tires with flat resistent ones
and dump the spare tire. If he is the only one in the car, remove a few
bolts and take out the extra seats. The door panels could also be removed
and thereby exposing the window motors which are quite heavy. Glue the
windows in place (that was standard feature on earyl 300M's) and remove the
window motors and regulators. If he is really serious, the ac and radio has
got to go.

 

These guys make one for the Hemi Ram, it's just a matter of time before they
show up for the 300c.

These cars do have great power, but more is always better. By the way
you're better off googling than asking about power chips on Usenet as you
can see by the helpful advice you've gotten so far.

 

No, actually your not better off.

If you google all you get is the chip manufacturers sales literature which
"proves" that if you drop $500 into their chip that your car will run like
greased lighting with a 50% improvement, sip gas like it's the last tankful
it will ever see, and quadruple the longtivity of your vehicle so that your
grandchildren will still be driving it.

If you ask here on Usenet where you will find people who DON'T have
a vested interest in these chips, you will get the truth which is they do
absolutely nothing that can be measured on a dyno, in return for emptying
your wallet.

The only time chipping a car does anything is if you have a turbocharger
and the chip you put in allows you to increase boost past the computer's
preprogrammed limit. Of course your turbo won't last longer than a
$5 whore on the docks when the ships come in, but if you know how to
increase boost in a turbo you probably know this too.

I think you've sent a new record for the amount of missinformation in
one post. The performance chips can make some improvement in normally
aspirated vehicles, especially those with auto trannies. They can
modify spark timing, fuel maps and shift points and this can all
increase performance, but at the expense of something else, typically
fuel economy.

And increasing the boost in a turbocharged engine isn't much harder on
the turbo, it is the engine internals that take most of the grief.

I'll take your word on the whore, I have no experience there.

i have heard there is some stuff on the way the new n.g.c software is playing
hell with the programers

 

No they cannot, unless you buy performance chips that are 'off-road-only'
ie: illegal to run on the street. And those will burn out your catalyatic
converter. And even then, if you don't do the other things needed - like
camming it, adding headers, etc. - you won't get the most out of an
off-road chip.

You cannot do any of that without making emissions exceed the legal
limits, unless the modifications are so slight - just a few percent - that
the rise in emissions is within the tolerance range, which on new vehicles
is not that great. And there's too many other variables - such as the
temperature that day, engine wear, etc. - which are going to matter more
than a legal perf chip.

Wrong again there. Most turbo engines use forged pistons and the
like and can readily take the higher power. As long as your not an
idiot and upgrade your fuel system so the engine doesen't go lean at
the higher boost, the engine isn't the problem.

The turbo is the problem because higher boost means higher turbo speed,
which means operating the turbo above it's maximum speed, ie: overspinning.
Sure, you can avoid a lot of trouble by using synthetic fuel, but the
turbo still takes a beating.

But that is generally not a problem for folks that increase boost and who
know what they are doing, since they generally are planning on getting
a bigger turbo anyway, they may as well burn out the stocker.

These perf chip arguments have come up on this forum again and again.
Every time they do, the chip proponents are challenged to take dyno
results proving their street legal chipped cars are better with the chip
than
without, that is when they slink off and we never hear from them again.

Thanks for your opinions. What evidence do you have that these chips do not
work? Have you any dyno results? Personal experience? Or is it just
arm-chair bullshit?

 

Thanks for your opinions as well.

Nobody that has bought them has reported measurable increases in power
for street-legal vehicles.

Every time that someone has posted about chips claiming that they really
sped up their vehicle, there has been a lot of attention, as you may well
imagine. Everyone after all wants to believe that there's a magic bullet
that only costs a few hundred bucks that will make a Yugo smoke it's
tires. During the subsequent Q&A with the original poster it is discovered
that the poster is either lying, (because they cannot answer specific
questions from others who have the same vehicle, or they won't say
where they got it tested), or the poster is relying on seat-of-the-pants
and hasn't measured it on a dyno, or the poster is a racer and has
chipped the vehicle with a chip that makes the vehicle illegal to drive it
on the street. (usually right after that the OP claims to not live in an
area that does emissions testing)

So, yes, I'll give you this much: if you live in the boondocks and don't
care
if your emissions aren't legal, and are willing to risk sooting up your
catcon
with a rich mixture, then sure, go ahead and put an off-road chip in the
vehicle. You will get a performance improvement - because one of the
fundamental tradeoffs in internal combustion engine design is that a
normally
aspirated engine produces more power if run rich. ie: the ideal fuel/air
mix for maximum power is richer than the ideal fuel/air mix for minimum
emissions. Unfortunately, this mix is not friendly to catcons.
