Moving pictures are better than photos. Here at PSI, we have a close-circuit high-definition camera in our dyno room. We have been working hard the last few weeks to create our own high definition online video site where these videos can be enjoyed by clients and enthusiasts. They can be viewed here, video player. We decided to create our own site for our videos to ensure the highest quality videos are available to our clients. We are currently adding new videos daily. Please be patient with the load times, we are working on speeding them up. Here is a teaser video, enjoy.

After waiting so long, Middlemas wanted a little something extra under the hood.  So, PSI replaced with stock engine with a slightly built LS1.  This engine definitely increases the performance of this Chevelle.  The LS1 is an aluminum engine normally found in a C5 Corvette.  This LS1 is a 5.7L small block V8 from Turnkey with 450 hp and 440 ft-lbs torque. The engine features Performance camshaft, double roller timing chain with billet gears, A.R.P. rod bolts, chromoly Manley push rods, heavy duty valve springs, and forged Mahle pistons.

Over the course of the season, AJC'S LS240 gets wear and tear from the events.  Damage from cones is often a result.  The drivers are pushing there cars the limit to get the most angle and fastest entry speeds possible and Andrew Coomes is no exception.  As a result, during the off-season and sometimes during an event, cars need to be repaired. 

blog raditor damage

During the course of the 2010 drift season, AJC's raditor and fan received some damage.  The fan and radiator will need to be replaced.  The damage was sustained during competition.  To prevent similar damage from occuring, protective bars were fabricated to protect the radiator.  The radiator is vital to keeping this built LS2 cool during competition.

Alex Laventure is welding the protection bar. 

This radiator protection will hopefully deflect cones or anything else that might seek to damage the radiator and fan.   The radiator protection consists of two additional bars.  The square tube and rounded tube.  Both of these are removable for easy access to the radiator. 

Andrew Coomes' LS240 is ready for the upcoming season, at least in regards to cooling.  The LS2 is still at the machine shop be disected and rebuilt.  Check back here or at AJCDrift.com for more updates.

AWD dyno is a powerful tool

At Portland Speed Industries, producing powerful and enjoyable cars are what we strive to obtain, however, customer satisfaction is our main goal.   To assist in our goal for customer satisfaction, we looked into alternative options that would let us better monitor a vehicle, on our awd dyno, that does not have a standalone engine management system or another ems solution to gather data from.  We have integrated a monitoring system that plugs into most OBD II cars and provides valuable information from the ECU.  The system graphically displays information in different formats depending on the specific data needed.

Being winter and having snow on the side of the road, most people would not take their car to get dyno tuned.  That is unless you drive a lifted 84 Chevy Blazer.  This truck was built for offroading.  It has a 6" lift on 35" tires.  3/4 ton Dana 44 in the front and a 14 bolt in the rear.  This Blazer has a 383 stroker mated to a Turbo 400 transmission with a 203 transfer case.

These baseline dyno runs were to check the air/fuel ratio.  The owner recently built the motor and wanted to make sure it was running properly.  Russ tweaked the carb to adjust the air/fuel ratio on cruise and idle for the motor break-in process.  The owner will return, after the break-in process is completed, to see the power of this built 383 stroker motor.
