890 RWHP with Factory Catalyst!

In the past it has been really difficult to make good power and pass emissions here in California. We wanted to come up with a package that would pass the strict visual and tailpipe emissions and make super car power. We used our EED forced induction ready engine package and Paxton smog legal supercharger package to meet this criteria.



We used a 2002 ACR for our first test. The 2002 models have the most stringent emission standards for the Gen 2 cars. We had to use a short overlap blower camshaft, to pass the miss-fire monitor, an exhaust and O2 sensors that would allow for quick 02 and catalyst warm-up and an effective sealed crankcase ventilation system.





The results were impressive. With 11-psi boost we achieved 890rwhp. The car has a lumpy idle and makes very linear power. Some other upgrades that really improved this build are our fresh air intake system and dual pusher fan upgrade.



Thanks to Greg Stocket for allowing us to do this build. We are excited about seeing it run at Mopar’s at the strip next week!

the build

We started with our forced induction engine build. This consists of a forged bottom end, better rods, bearings, pistons, balancer, timing chain, blower cam, low bleed lifters, oil pump modifications, head studs and JM head work. This is a pretty good foundation for up to 900rwhp. The fuel system is upgraded with a modified tank module, external pumps, regulator and bigger fuel injectors. The exhaust is an E.O header with heat shields, factory cats and Corsa Catback. The SC System is an off the shelf Paxton E.O legal kit with a pulley change. In order to reduce intake temperatures we added our fresh air intake system and pusher fans.

Here are the results...



The production catalysts are pretty stout even when you double the hp of the engine. The key is to keep the air fuel ratio right so you do not overheat them. If used on the track for continues wide open throttle sessions their service life would diminish. For a track (off road) application we would delete them. Here is the air fuel and boost information for this build:

Our in-house tuner can tune your Dodge vehicle!
We also sell MB Products and are a certified KLEEMANN dealer!

This Package can be done on the Ram SRT 10 with some minor changes.

Our basic SC packages start about 11k installed. For a bigger build I would want to give you a quote as it would depend on your current modifications
and use of the vehicle.

Sounds like a very reasonable price DC. That wou'dn't include the built motor, I'm sure. Do you use AEM EMS to tune the snakes?

At what power level do you guys start redoing the bottom end on the 96-99 stock forged bottom end models?

On the forged bottom end cars we feel comfortable with power levels up to 650rwhp for the street. Higher numbers are possible but reliabilty could suffer without better parts.

Yes we can and have tuned many vipers with the AEM engine management system.

We are also one of the few shops that specialize in tuning the factory "JTEC" engine controller. On most applications we can tune the car without adding a piggy back or aftermarket engine control system.
