Paxton Supercharger Evaluation

[Daniel Cragin/DC Performance Inc]

We have done numerous of these installs with great results. With any new product we have noticed a few things that can make this setup work better.
The cars do run hotter, seem to have more chassis flex, and those with headers and no heat shields can run into some heat related electrical issues. Overall I applaude Paxton and their chief engineer Chris Whalley for a job well done.

With a little experimentation we have come up with resolutions to all these things. There are also a few tuning tricks to make the setup more powerful without sacrificing reliabilty.

This kit can be upgraded for more power with some small changes. We really do not like to tune these systems over 750hp because the engine really is not built for it. We have overhauled many a engine in the past and have found the connecting rods are the weakest link. The engineers at DC agree, better to error on the safe side. The cast piston cars do not like more than 6psi but with some head work and fuel system upgrades can make 650rwhp no problem. Add a cam change and at 6psi weve seen 680rwhp. These are not huge numbers but they were made with low boost and long term reliability in mind.

The biggest limitation to this kit to make more power is the fuel system. Just fine for a stocker with headers and rocker arms but anyhting more requires
a injector resize, pump change, and some computer tuning. Real power requires a proper fuel system. Any change from stock requires a little FMU tuning to get the air-fuel correct. If you can data log A/F on the dyno it really helps to get it right.

We soon will be finishing a proper fuel system upgrade that will be track
friendly and will work for open road race events such as the Silver State.
Most the tuners who make big hp warn not to run less than a 1/4 tank or you
may starve for fuel.

With the help of AEM and Paxton we are doing a 14-18psi system with a purpose built engine. We are excited to see the results.

For any of you interested in doing this Paxton setup, I think we have a very good knowledge of this system, we helped develop and prototype it and have learned through experience how to make it work best. We welcome your inquireys and questions. Let us know if we can be of any help.

Dan:

Very informative evaluation.

Much appreciated.

So when are you guys going to build a Gen-III system, already? Liz's 509 RWHP car is feeling slow next to its older brother

Do you have an estimated cost to this upgrade? Dan, do you sell cams that will work well with the paxton set up?

 

[Daniel Cragin/DC Performance Inc]

To answer your questions:

1. We are currently working with Paxton on the Gen 3 kit.
2. We have two camshaft profiles that work good with superchargers.
3. Our base package is $9300 installed. This includes our modifications to
the system and tuning. Modified engines and higher boost levels require more
work. Cooling system upgrades and dyno testing are extra. We take pride in all
of our work and it is reflected in the finished product.

how much for the cam and fuel system minus the paxton kit?

Dan, is the Paxton kit CARB certified?

 

[Daniel Cragin/DC Performance Inc]

For specific pricing on components just give me a call and I can discus your needs and give you an estimate.

Yes, this supercharger kit is the only system that is carb certified and smog legal. It will pass a visual inspection and tailpipe emissions test. This is also a big plus if you ever decide to sell your vehicle.

Freekin OUTSTANDING!

As soon as I can get the money out of my wife's grasp, I'm in.

"The cast piston cars do not like more than 6psi but with some head work and fuel system upgrades can make 650rwhp no problem."

Dan,

What about those with forged pistons? Would a '99 still need head work for 650 - 750 HP?

 

[Daniel Cragin/DC Performance Inc]

The forged piston cars can run more boost. We try to limit the rwhp on stock
forged piston cars to 620-650 rwhp because of long term limitations of the bottom end. We have raced production, supercharged forged piston cars at 620rwhp with no short term issues (600 competition race miles on a 17,000 mile engine).

We run up to 10 pounds on the 96-99 forged piston cars and have yet to see a piston problem.

For those of you who plan to club race a supercharged car over 600 rwhp we recomend a blower specific botton end and upgraded cooling system.
