Stage 1 on a 2004 H.O.

[dc3_1132]

Hi everyone!!
I just hit the jackpot last weekend and found my DC3. (#1132)
I am wanting to do some minor tweaks to her. ( I know, once you start you can't stop)
I have started the airbox mod and I am going to build a new charge pipe hopefully this weekend. Having already spent several hours on here reading about stuff, I figured I should go ahead and register so I can talk to everyone.

Now, the real reason for posting this. I have read mixed numbers on the Stage 1 kit. Honestly, on a '04 H.O., will I get 235 hp at the crank, or at the wheels if I put the Stage 1 ECM on the car?

Welcome to the forum.

Found this in a search....

"For '05 and up you upgrade to 235hp 275 ft-lbs torque measured at the Wheels.
The original Stage kits up to and including '04 were measured at the crank, you have 10 to 15% loss with a 5 speed manual trans and 20% with the auto trans."

Well that is silly!!!

I expected the 03 and below (turbo-lites) to be at the crank, but not the H.O.

What difference is there between the '04 and the '05

[dc3_1132]

What I mean is what is the difference in the H.O.'s from '04 to '05. If you look up the hp #'s, I am pretty sure they are the same. If I am thinking right it was '06 before Chrysler switched to the plastic intake giving the PT's 10 extra horsies (220hp-230hp)

Sorry, your going to have to wait till one of the Turbo owners that know more about the information your looking for to come along and help you with your questions.

Maybe some 05's Ho's slipped from the factory with plastic intakes because thats what my 05 HO has stock

They did, but Chrysler still said 220 crank hp stock on the '05 even though it was really 230 crank hp with the plastic intake. For '06 the GTs all came with the plastic intake and 230 stock crank hp.

After doing some research it appears that about mid-'05 is when the intakes were switched. So, some '05's will have plastic intakes and some will have aluminum intakes.

When you buy stage 1 for 03 you get the bigger injectors, looks like you get the bigger injectors with 04 too.

You don't get them (already bigger from the factory) with 05 onwards, so this and the plastic manifold should let you know what hp to expect.

our 05 has a plastic manfold
