Skip stage 1 and go directly to stage 2?

And ALL SRT4s are manual.

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.

The original specs in the '04 Mopar manual are:
Stage 1 235 hp 240ft-lbs
Stage 2 260 hp 280 ft-lbs
Stage 2 with toys (SRT4 only) 265 hp 280 ft-lbs
Stage 2 (High Octane Mode) 280 hp 300 ft-lbs
Stage 3R (SRT4 only) 310 hp 325 ft-lbs
Stage 3R (SRT4 only Hi Octane Mode) 355 hp 365 ft-lbs

With the '05 and up measured at the wheels at least 5 of us over on PT Crew have dyno'd our cars, (mine just this past Saturday) and we all made 235 +/-5 whp 290 to 305 ft-lbs torque to the wheels, now if you add back in the trans losses 20% for the auto you have 282 hp at the crank, 360 ft lbs at the crank.

So for the '05 and newer with Stage 1 and a free flow exhaust and take the restrictions out of the stock air box and intake tube you are past the original PT and SRT4 Stage 2 specs.

Now I will not go any higher until I have my auto trans upgraded for more power.

Thanks so much for the info!
I am planing on getting a free flow exhaust, down pipe, up pipe and a k&n cone filter intake.
Along with new plugs, whires, WGA, trottle body spacer, BOV conversion kit and intake manifold heat sheild.
But what about fuel injectors?
The stage 1 only has them for the 2003 model!
I was just going to get them sepretly with the stage 1 then I saw a stage 2 for the SRT that came with injectors so I though I would try and do that, I guess I should just go with my original plans.
And dont tell me that the stock injectors are more than I need because I need more power!!! Arr arr arr
I was planing on getting my injectors at RC something like...

Flow Rate - LB's:
35 LBS / HR @ 43.5 PSI

I was looking at the peak & hold but I am not sure which whould be better, the peak and hold or the saturated.

The stage 1 only has them for the 2003 model! That's because the injectors were made larger in '04 on all turbos. The injectors you get for an '03 S1 are what you already have

If you're serious about performance, go to PTCrew.com - Learn it or Burn it. there are some gurus there.

As for the auto tranny being too weak for Stage 2 line you are on PT Crew. Everybody there knows the 41TE auto tranny is weak. Heck, I lost one on a 150 hp NA PT. DCX knew they'd open a hornet's nest if they went ahead with S2 and S3 for the PT. 95% of all PTs are automatic.

Well, he said, she said, I was only going by the Mopar Performance Printed Material in 3 years worth of catalogs, and had not heard other wise even over on the Crew where most of the tech info is reliable, you would think that if it really made more they would publish it to sell more product if they were bigger and better.

I know the trans are weak, that is why it is next on my mod list, but my point was that the '05 and up Stage 1 kits provide higher numbers than the older Stage kits kits did, I have seen the dyno numbers from both and there is a 30 to 40 hp difference with simmilar mods between the '03,'04s and the '05 & up.

But anyway thanks for your input, it is always good to hear documented info, I aways thought they under rated the HP on the SRT4s anyway for the younger drivers insurance. But after I upgrade to a "AJ" trans with my tax refund I already have Stage 2 injectors and Stage 2 WGA waiting for install with some type of fuel management.(hopefully a SCT unit) I am hoping to reach 300whp 300ft-lbs (I already have that torque as long as it does not go down)with out upgrading to a bigger turbo, but If I have to then I will go with one of the stock fitting "Turbofold" types.

Do you have a link or webpage with your mods or would you have to kill me if you told me.

Thanks again for the corrected info.

Butch

PS. For those that want to see I had posted my dyno sheet over on PTCrew and you can see my mods in the link in my sig. PTCrew.com - Learn it or Burn it.

As others have stated,,, the 41TE in stock form won't take the HP. Heck,,, stage 1 puts it at serious risk. Beyond that,, the pin is pulled. I have trashed a few,, including two so called high performance from Power Demon. A friend of mine has a ton of auto experience,, has done a lot of R&D with my car,, and has made great leaps in getting the 41TE to survive higher HP levels. The weakest point seems to be the OD section. Stock it as 4 clutches,, a lot of folks have put 5 in,,, mine and a couple of others now sport 6 in the OD. BUT still the warning is do not boost in OD. AJ has done other major changes to the 41TE.

SO no S2, but there have been some interesting developments last year,,, A company called SCT has released a flash tuner for Mopar. I am currently testing one in my PT. It has the capability to go far beyond S2 programming.

What can those of us with a manual transmission expect? can we safley add stage 1 with a few other after market bolt ons or is that pushing it for our stock transmission?

With the five speed you'll be fine.

If you really want to mod things out the Eclipse 6 speed Tranny was designed for a car running 330hp. my mechanic buddy checked the block pattern it will block directly on.

Also check out Youtube there is a video of PT on a dyno running 599hp 649 lbs torque. Anything is possible if you have the bucks

Yep, I'm going to watch him run at the track this summer.
