Supercharged Toyota Sequoia.jpg

A few months ago, Alex Laventure fabricated an exhaust system for one of our client's supercharged Toyota Sequoia.

PSI Custom Exhaust on 2011 Toyota Sequoia 001.jpg

The larger diameter exhaust and MBRP tip gave the exhaust the look and sound that the client was looking for.

The client recently returned and wanted us to install a new set of headers and continue the custom exhaust up to those headers.

Alex welding Exhaust

Alex did some welding and fabricated a section to go from the headers to the rest of the exhaust.


This not a simple job of running a relatively straight pipe. The exhaust was routed along each side of the transmission and joined up at the muffler.

The owner wanted a little more out of the exhaust system and the headers and exhaust modifications gave him what he was looking for.

GReddy Twin-turbo 350Z on the dyno at PSI 001.jpg

Following a referral, a local dealership brought down a twin-turbo Nissan 350Z for tuning. The 350Z had a low boost GReddy twin-turbo kit and a Haltech Platnium ECU.

Twin-turbo VQ35.jpg

Having tuned a few single and twin-turbo 350Z, the dealership felt confident that we could do the job. Their main focus for the car was drivability. They were not going for a high horsepower record but wanted the car to be once again fun to drive.

With a safe tune in mind, Jason Oefelein began to tune the car. On the first run, the air/fuel ratio throughout the band was definitely not where he wanted it to be.

After several more pulls on the dyno, the tune and air/fuel ratios were looking a lot better.

A typical 350Z makes around 230-240whp in stock form. With the GReddy twin-turbo kit, this 350Z puts down 315whp and 261 ft-lbs of torque at 6 lbs of boost.

Here is a video of this twin-turbo 350Z on the dyno:

While there, they let Professional Driver, Justin Pawlak, put it through its paces.

We have used their universal components on a variety of our customers cars and have been very impressed with the quality. The owners come from engineering backgrounds and this is evident in the design and development of their various products.

Check out their website or come in and we will be glad to talk to you about this and other products from Radium Engineering.

The following is from their website and describes a little about this kit.

"The Hard Parts Turbo Kit is a complete bolt-on kit and includes everything needed with the exception to the engine management system and any engine wiring harness adapters. NOTE: In late Fall 2011, we will be releasing our Lotus Plug N Play Programmable EMS. This Hard Parts kit is ideal for someone using a stand-alone EMS, piggy back ECU, or reflash ECU that their tuner is comfortable using.

This kit is designed to be a complete bolt-on system that requires no special tools or permanent modification to the car allowing the vehicle to be returned to stock if necessary. Furthermore, all factory equipment is retained but the relocation of certain items is required for proper installation."

Here at PSI we have a wide variety of cars on the dyno. On the same day, there could be an modern import car followed by a classic American car. One day, we had this 1967 Chevrolet Camaro.

67 Camaro on the dyno for tuning 2.jpg

The dyno is used to not only give you performance numbers like horsepower and torque, but also lets you know how your engine is running. While on the dyno, we monitor the air/fuel ratio and also boost pressure when applicable. Maintaining the proper air/fuel ratio throughout is important to not only make power but to keep the engine safe.

This '67 Camaro is powered by a 383 Stroker TPI engine with a mild cam.

67 Camaro on the dyno for tuning 3.jpg

The Camaro was strapped down to the dyno and ready for a few runs. During the first run, the air/fuel ratio was very poor. A full run was not made because the ratio was too lean. Not only did the Camaro produce very low numbers but running with such a high air/fuel ratio was dangerous for the engine.

It was apparent that this Camaro needed a tune. A tuning solution was found that included the use of a Tuner Pro RT. Jason Oefelein tuned the Camaro for a safer air/fuel ratio throughout the power band. After the tune, the Camaro produces 278 whp and 333 ft-lbs of torque.

Here is a video of the run:

Keep a better watch over your engine with AEM's 4-Channel Wideband UEGO Controller. Collect useful data about your engine to help increase power and safety. Here is a little from AEM's website

OVERVIEW AEM's 4-Channel Wideband UEGO Controller is a powerful, cost effective tuning tool that allows users to monitor the Air/Fuel Ratio (AFR) of up to 4 individual cylinders simultaneously (or up to 12 cylinders if multiple units are paired together). This unique controller features an optional exhaust back pressure compensation* kit to correct AFR readings of Wideband sensors mounted pre-turbo. The system includes stainless steel bungs specially designed for use in individual port applications which feature a finned stand-off design which both cools the sensor body and minimizes exhaust port restriction. The 4-Channel Wideband UEGO controller is ideal for datalogging, engine management systems or racing applications where individual cylinder trims are needed. The system features simple wiring and installation with 0-5v analog outputs for each AFR channel as well as a CAN datastream output. The controller is shock & weather proof and can be mounted anywhere in or outside the vehicle. MAXIMIZE ENGINE POWER AND SAFETY When tuning an engine, accurate Air/Fuel Ratio data is critical. Running rich can cause a loss in power, while running too lean may result in serious engine damage. The AEM 4-Channel Wideband UEGO Controller is a must for anyone using an engine management system or data logger to monitor individual cylinder AFR in an effort to maximize engine power and safety. Many modern engine management systems, including the AEM EMS, are capable of utilizing individual cylinder fuel trims and the 4-Channel Wideband Controller provides tuners with the precise information required to tune each cylinder to a targeted AFR. AEM's innovative exhaust back pressure compensation feature* allows the wideband sensors to be mounted in each exhaust runner pre-turbo, which eliminates the need to measure an average AFR over multiple cylinders on turbo charged applications. The system can be integrated with almost any data logger or engine management system through 4 unique differential analog outputs or the AEM CAN datastream output. The Bosch 4.2LSU sensors, which give the controller its speed and accuracy, are laboratory calibrated at the factory and never require free air calibration! The unit features a shock and weather proof housing, allowing it to be mounted virtually anywhere in the vehicle without worry.

The Subaru WRX has been a popular platform for modifications over the generations and the new third generation is no different. A client recently brought in his WRX for a few performance upgrades, including a Cobb Accessport.

Most of the modifications focused on reducing airflow restrictions on the Boxer engine. A Perrin intake and front mount intercooler (FMIC) allow better air flow and lower intake temperatures.

White WRX with Perrin Products

A Perrin catless downpipe and turbo back exhaust were also installed.  A Cobb AccessPort was used to reflash the ECU to get the full benefits on these performance upgrades.

Here is a video of the dyno run:

This new setup produces 309 whp to the wheels.

The WRX also received some upgrades in the suspension department. The stock components were replaced with Tanabe Sustec Pro Five coil overs. These give the WRX the lowered stance and increased handling performance the owner was looking for.

AEM’s Dyno-Shaft on-vehicle dynamometer system is literally a dyno on your car. It provides Horsepower and Torque numbers by measuring a vehicle’s Torque and RPM at the driveline, while you drive. It allows you to gather information under real-world conditions.

A little info from the AEM website:

Eliminate Guesswork - Know for sure if slower times are due to a loss of power, vehicle set up or driver error.

Engine tuning - Stop trying to approximate real world test conditions and start testing in the real world! Finally you can test with actual intake air conditions, actual vehicle loading and the hundred other things that make a real vehicle behave very different than it does when on a dyno.

Chassis Set Up - Know when the tires will break loose. Ideal for optimizing drag launches and determining the longitudinal forces your tires can handle in road racing.

Torque Converter and Clutch development - Finally know what your Torque converter or clutch is doing while you are making a pass!

Dyno It All - The Dyno-Shaft accurately reads in all conditions including steady state, uphill or downhill, even while coasting down!

RECORDING, READING AND OUTPUTTING DYNO-SHAFT DATA At its core, the Dyno-Shaft is a sensor that measures Torque and RPM and uses this data to output a vehicle’s Horsepower and Torque in real time. You will need a ‘host device’ to record, view and output data from the Dyno-Shaft.The following devices are capable of reading and logging data from the Dyno-Shaft via AEMnet:

  • AEM AQ-1 Data Logger
  • The AQ-1 is the ideal host device solution for the Dyno-Shaft as it provides the broadest set of features and functionality, including:
  • The ability to create dyno charts which can be saved, printed or shared electronically.
  • The AQ-1 is a full featured data logger, so continuous power data can be recorded and replayed along with a wide variety of other vehicle information. See AQ-1 product page for more information.

See the screen captures below for outputted dyno graphs from the Dyno-Shaft and ease of set up.

AEMData - Dyno-Shaft Data Plot AEMData - Dyno-Shaft Dyno Plot AQ-1 Dyno-Shaft Configuration Screen 1 AQ-1 Dyno-Shaft Configuration Screen 2

  • AEM Series 2 Programmable EMS
  • Like the AQ-1, the Series 2 EMS allows logging of continuous power data which can be replayed along with a wide variety of vehicle information however this device currently does not feature the ability to create dyno charts. This functionality will be added in the future.

Certain CAN-enabled devices from other manufacturers are configured to read Dyno-Shaft data. If you do not have one of the AEM devices listed above you will need one of the devices listed below, and will need to confirm that it can read the data from the Dyno-Shaft by contacting your manufacturer:

  • CAN-enabled Data Logger
  • CAN-enabled Programmable Engine Management System
  • CAN-enabled Racing Dash

The dyno-shatft on-vehilce dynamometer is offers in two forms, Sportsman and Pro series.

One of our clients has been developing a supercharger kit for the 4.0L I6 Jeep Wrangler (TJ).  He wanted to see the benefits of his kit so it was time for a dyno test.  We previously ran his Jeep on the dyno and it put down 132 whp and 197 ft-lbs of torque.

SC Jeep Wrangler on the dyno at PSI.jpg

With the new kit, there were definitely improvements in both horsepower and torque.  Check out the video,

SC Jeep Wrangler Convo.jpg

After the kit was proven, the owner talked a little with Jason Oefelein and Erick Sackhoff on the next steps for his kit. They added some input from their many years in this industry.

The client was happy with the results. If you have a 4.0 TJ, this kit maybe something you are interested in, so check back here for more details in the future.

This past weekend, Wally brought down his recently finished Ford Mustang. The Mustang's 530 ci V8 is now supported by twin 88mm turbos. This Mustang was being tuned by Jeff and the goal was to max out the Dynojet dyno. This new setup reached that goal with power to spare. Here is the video of the record breaking run and some photos to follow.

A client recently brought down his Nissan 300ZX Z32 to get tuned by John Reed. This Z is no longer powered by a VG but by a 2JZ out of a Toyota Supra. 2JZ's are swapped into a lot of different cars. We even had a 2JZ powered Ford Coupe.

2JZ the heart of a Z32.jpg

This 2JZ is being force fed by a HKS T04Z turbo. We strapped the car down so that John Reed could tune it.

We have been busy and Halloween snuck up fast this year. We set up a small haunted house in only a few days for family and friends.

But this year we wanted to do something different. Instead of passing out candy to kids who came by, since hardly anyone stops by the shop on Halloween night, we decided to bring the candy to them.

When delivering candy on Halloween, a proper vehicle is needed. It just so happens that Erick recently picked up a Chevy Stepvan.

Stepvan in front of PSI 001.JPG

One of the 15" Dayton's had a bad valve stem so Erick replaced the 15's with a set of 22" Dayton's. With a new set of wheels, it was time to decorate the rest of the van for Halloween duty. A power inverter was installed to power a fog machine, red lights, and a iHome for the scary music. A large spider and hanging head finish up the interior.

Stepvan Monsters at PSI.jpg

You can't pass out candy in the Stepvan without costumes. The guys dressed up as evil clowns and monsters.

It was a lot of fun handing out candy from the Stepvan. This might become another Halloween tradition for PSI.
