This particular Cobra has a 460 under the hood.  We currently don’t have performance numbers for this cobra because it spends its time on our showroom floor.  We hope to have it on the dyno soon. 

The truck is a Pro Stock 1956 Chevy Truck. 

With a parachute and wheelie bars, this is a very fast ‘56 Chevy.  The owner/driver hopes to break into the 8s with this setup. 

Under the hood is a fully built 565 cid Chevy V8. 

This engine is running at 14.7 to 1 compression.  The list of parts is extensive and from the best component manufacturers.  Power is transferred to the ground through a Turbo 400 with 4:10 gears.

Here is the video.

The night before, they were using our dyno to do some tuning before the race.   

Getting the car ready to race.

Lined up and ready to go.

The 1967 Chevelle left on a truck to the east coast today. 

After two and half years working on this complete frame off restoration and modification, it is a sad and happy moment seeing it leave.  It is sad seeing a car leave that you have spent many hours working on over the past few years.  But also a happy moment, since the project is finally done and the client can enjoy the car you work so hard on. 

Also leaving on the same truck is a Toyota Supra.  This Supra is also heading to a client on the east coast. 

The Supra received an AEM EMS and a tune before heading to its owner. 

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,

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.

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.

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.

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.

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.

And here is the video:

2009 Porsche 997 GT2 on dyno at PSI from Portland Speed Industries on Vimeo.

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

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. 

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