One of our clients who recently moved back to Cali, was featured on HellaFlush/Fatlace's website. 

Here is a link to the feature, http://fatlace.com/hellaflush/hellaflush-invades-the-paddock/

His car is the third car, the silver S2000. 

Here is a link to a write-up about Eric's S2000 on our blog, http://blog.tunedbypsi.com/turbo-s2000-pt5857/.

It also includes a video of his car on the dyno. 

Eric's car is a good example of the kind of car we like, it has clean look with power to match.  The subtle exterior and interior modfications compliment the S2000 lines.  With the PT5857 turbo, Eric's car put down a respectable 387 whp and 264 ft-lbs of torque on our dyno. 

Eric also took his S2000 the HellaFlush 6 BBQ at Coyote Point.  He also made it onto their write-up of the event, http://fatlace.com/hellaflush/hellaflush-6-bbq-snaps-p1/.

Here is a photo taken from that write-up,

A 1955 Chevy Bel Air is a beautiful car from the 50s.  The unique lines and curves set this car apart. 

Bel Air front

The owner of this Bel Air has been restoring it and modifying it.  He is making this Bel Air into a hot rod.  The original V8 was replaced with a 502 big block V8.  The carb was also replaced with a fuel injection system by ASM.

 Bel Air Business Park

The reason the owner brought the Bel Air to us was because it was in need of a tune.  When it first arrived, the car had a rough idle and was just not running right.

Jason Oefelein began the tune by creating a base map.  Tuning continued on the dyno.

Here is a video of it on the dyno.

For some, a 3.5L V6 is just not enough.  A client of ours wanted more horsepower and torque without relying on forced induction.  This client has a slightly built LS1 to drop into the now vacant engine bay.

Empty 350Z engine bay

This V8 produces more horsepower and torque than the smaller V6.  The deep rumble of the V8 is an improvement.  People will not be expecting a V8 exhaust tone from a Nissan 350Z.

The LS1 fits in nicely in the 350Z engine bay.  Alex needed to fabricate a custom intake for this setup.  The space constraints made this difficult. 

We used Sikky Manufacturing's LS1 350Z mount kit in this project.  Sikky headers were also used.

Alex needed to modify the exhaust to work with this new setup.

A Monster Clutch was also installed with the LS.  Monster Clutches are high performance alternatives to the OEM clutch.

And now for the dyno video.

With the LS1, this 350Z put down 445 whp and 426 ft-lbs of torque.

Two clients brought down their 1970 AMC AMX's.  Upon first glance, these two cars look almost identical.  They are both a deep green color with 390 cid V8's.

1970 AMC AMX's infront of PSI

It is rare to see an AMC AMX and even rarer to see two of them.  These two fine examples are owned by two brothers who share a passion for cars.  Although the outward appearance of the two cars are similar, each one has small touches that set them apart.

We had both of these AMX's on the dyno. This first one has a stock head and moderate cam. Power is put to the ground through an automatic.

The second AMX had some head work and an aggressive cam.  The 390 is mated to a manual transmission.

Yesterday, we had a client bring in his 2009 Porsche GT2.  This was no ordinary GT2 but had Evolution MotorSports' EVT640 kit on it.

Of course we strapped it to our dyno to see the power it puts down.  A stock GT2 is rated at 523 hp and 500 ft-lbs of torque at the crank.

The car put down 596 whp and 669 ft-lbs of torque.

A client came to us with his 2008 Infiniti G37S.  He talked with Jason Oefelein to see the direction he wanted to go with his car.  The client wanted to have an increase in power, while maintaining the reliability.  A Stillen supercharger was chosen for this project, along with Stillen headers and an HKS exhaust.  The car also recieved some Tein performance springs to replace the stock ones.

We dynoed the car in its stock form and it put down 287 whp and 242 ft-lbs of torque. 

A Stillen supercharger kit, Stillen headers, HKS Exhaust, and Zeitronix wideband monitor were installed.

The HKS Dual exhaust looks good.

The Stillen supercharger fits in nicely.

The Zeitronix monitor was stealthily installed where the ash tray and cigarette lighter once were.  The Zeitronix monitors the air/fuel ratio, EGT and air intake temp. 

And of course, we put the car on the dyno to see the improvements.

Here is a before and after comparison. 

blog dyno-template-before-and-after

The horsepower went up by over 120 and the torque increased by 70 ft-lbs.  Not bad gains from with this new setup.
