04 SRT/Paxton Supercharger 651rwhp and 591rwtrq!

[Daniel Cragin/DC Performance Inc]

We just completed another Paxton SRT10 supercharger installation. This car was completely stock except for Corsa exhaust. Results were spectacular to say the least, a 49% increase in power. Here are the results:


Baseline: 436 rwhp 459rwtrq

Paxton/ Corsa: 651 rwhp 591rwtrq


This car made about 45hp more than the last vehicle we tested (only difference was the exhaust). The install went smoothly and everything has been quite repeatable. As of yet we have not had to do any special tuning.

Dan are you saying this was the Paxton kit unadulterated? If so Wow!

How much boost is it running?

 

[Daniel Cragin/DC Performance Inc]

This was the stock Paxton kit without any changes. The only thing done to this car was a Corsa track exhaust and
the richer FMU disc supplied with the kit.

Hi Dan,

Good numbers.

What does the power curve look like on this set-up? Could you post the dyno sheet?

Nice #'s


lets see that bad boys dyno sheet.

How long do you need the car for the install?

 

[GR8_ASP]

Okay, 2 insti prints. Not good but fast. The radar unit is above and to the right of the mirror. The remote unit is to the left of the instrument cluster near the A pillar. All wires hidden. If you look close you may even see a car seat in the mirror - went on a poker run yesterday and did not remove it yet.

Hey Ron! I was reading the V1 install thread and am glad to see your pics. Even though you put them in the Supercharger thread by accident!

Dan,

I was planning on adding a supercharger to my 2004 SRT and am considering a few things...:

1) want a supercharger that can be removed without taking too much time and returned back to stock for warranty purposes (is this realistic)?

2) Sean and Roe Racing says that he will have a all-new twin-screw supercharger available during the winter for the SRT... I have read mixed opinions on the twin-screw vs. the centrifugal (Paxton)... I will take the car to the local track to run 1/4 mile times RARELY and mostly just like the "punch" or "throwback in the seat" you get on open roads...

3) What octane is required? My 2004 owners manual says that stock car requires 93 octane but only 91 octane is widely available here in Las Vegas (near my home anyway)... I was also told that the air here in Vegas will negate some of the need for that extra octane requirement? Will a bottle of octane boost work to solve this?

4) Do you have any recommendations for someone who could install this in Vegas?

-currently have the complete K&N filter system and Corsa Track Exhaust (no crossover)
-also have the best (according to Jon at Partsrack) non-ceramic RT High Flow cats but my local Dodge dealer said that they couldn't take off the stock cats (especially the one closest to the manifold, since it would require a special curved pipe fitted to replace)...

Any thoughts? Recommendations?

Thanks,

Mark

Dan,

I thought about driving the car out your shop for the work but thought it would be better to be able to have car worked on (if any issues develop) locally here in Vegas... Was also thinking of installing the Unitrax 3.43 gears with their upgraded PIN... and possibly using different rear tires (much software ones that the run-flats to get better grip on the street, only put on about 200 miles/month).

Howdy Folks!

Any opinions of a centrifugal (like the Paxton) vs. a positive displacement (like the Roe) for road racing? When I was shopping forced induction for my soon-to-be-replaced-with-a-Viper current car, I had some people suggest the PD type was better for a couple of reasons: 1) Easier to modulate the throttle since it's power is much more linear, and 2) Produces less charge temperature.

Any truth to that? On a vette, the current PD solution by Magnuson, has peak power much less than the available centrifugal solution by like ATI, Paxton and Vortech - and the Mag has been used by a number of people road racing (a couple of guys here in the south) without any issues.

I've read here that since the Roe system sits right on top of the motor, there's some heat transfer that you don't get with a separate blower that's somewhat isolated (?)

I think in terms of opening the hood of your Viper and making the men quiver in fear and the ladies fall faint, the Roe takes the prize! Wow, does the polished setup look *amazing*.

Sorry guys for putting the V1 pics in the wrong thread. But I guess you can see which one I am more interested in

If a moderator sees this you would be more than welcome to move my picture post above to the V1 thread.

I cannot really comment honestly on the Roe Gen 3 system as I have not installed one yet. It does appear more refined than the earlier setup. We have installed and tuned his earlier systems and found them well engineered and better for low rpm power. They do seem to be suseptible to heat soak and sometimes require some special tuning. All in all, a very good package with great product support.

The Paxton system has produced better peak power for us and is less susceptable to heat soak. It is also CARB certified and legal in all states.

We are happy to install both systems and feel they both have advantages of their own. The choice is up to the customer. Both systems can be removed to put the engine back to stock. Technically any engine related problem not caused by the addition of an aftermarket product should be covered by the factory warranty. See your dealer for their policy regarding this.

The Paxton unit is tuned for 91 octane gas and in our opinion is tuned conservatively for reliability. I do recommend that you have a authorized installer do the job and qualify the tuning on a chassis dyno before delivery of the vehicle (I recommend this for any supercharger install).

If you wish to buy either of these systems from us, we will give you all the product support you need.

So how long does this install take at your shop?

 

[Daniel Cragin/DC Performance Inc]

We usually need the car for a week. We dyno test the car first and check it for any problems. Once the car is finished and re-dyno tested; We like to put 50-60 miles on it and double check everything.

 

[DB/Paxton SRT-10]

I am the delighted owner of the 2004 SRT-10 that had the installation of the Paxton Supercharger producing 651 rwhp. I picked the car up two nights ago from Dan Cragin at DC Performance. At idle, there is a very soft whistle that is barely audible above the Corsa exhaust. It is not detectable during driving except when you take your foot off the throttle and the bypass valve opens. At low speed the car drives very much like stock but is perkier throughout the lower rpm range. Above 3000 rpm, it feels like it is being pushed by the hand God! Dan reminded me three times to "be careful"...now I know why. The installation was neat and clean. I couldn't be more pleased.

can someone post a dyno sheet please.....


vd..

 

[quickysrt]

take it to the strip please.

 

[MannyC]

GHa! I want to get my SRT10 Turbo charged so bad right now! I have a blower car already, so I want to try the trubo route and see which I end up liking better so I can do that to my next super car (not sure what that is just yet.)

[Daniel Cragin/DC Performance Inc]

I will try to get the dyno sheet up this week. Thanks for all the interest!
