A client recently installed a Precision 5857 turbo with a PFab equal length kit into his 2001 Honda S2000.  He then trailered the car to us to have Jason Oefelein tune it on AEM.

This past weekend at our Summer Cruise-In, a vehicle broke the current high horsepower run on our dyno.  The twin-turbo Dodge Viper SRT-10 that held the record was running on pump gas with water/meth injection, the new record holder was on race gas.

The Viper was beaten by another vehicle powered by a Viper V10.  This 2005 twin-turbo Dodge Ram SRT-10 put down 1260 whp and 1192 ft-lbs of torque.  With a race gas map, the truck was able to make this much power from the V10 with the help of two GT42 turbos.

We will just have to wait and see how long this Twin-Turbo Ram SRT-10 stays at the top.

The Acura NSX is a great car.  It is often referred to as a supercar.  A client of ours acquired one earlier this year.  It is a black 2004 NSX. 

Acura NSX after a detail

Our client did not care for the appearance of the stock air box so he told us to fix it.  We removed the air box and replaced it with a K&N cone filter.  Having the filter hanging off a aluminum tube cause issues with movement.  The air filter would hanging at the end and hit other nearby components. 

To solve this issue, Alex Laventure, our in-house fabricator, began working on an intake mount.  He took some measurements and began fabricating.

Jason Oefelein recently went to Hagg Lake to tune a 23 foot boat.  This boat had a throttle body injection 460 cid V8.  The engine was initially carbureted but was changed to TBI because of the lack of consistence with elevation changes.  Jason used a Holley Commander 950 and a custom air/fuel monitoring system to tune this boat.

The Toyota Supra that we fabricated a turbo "kit" for is finally completed and on the dyno.  The setup includes a 2JZ with a Garrett GTX4294R.  This 71mm turbo needed to be located below a TRD strut tower bar so a custom turbo manifold was fabricated.

Now that fabrication is completed, it is time to test it out.  We strapped the Supra to our dyno for some tuning and to see the power it puts down.

We finally have been having nice sunny weather.  Since it is halfway through July, it is about time.  I hope this weather continues until September or at least for the next two weeks. 

Because, on the July 24th, we will be having our first annual Summer Cruise-In and dyno exhibition.

The owner of this 1964 Corvette brought it down to PSI because it had drivability issues.  It has a carburated 383 stroker under the hood.

The Corvette came in with an Edlebrock carb, which was giving us problems.  We switched it out for a Holley 670 cfm Street Avenger carb.

The 71mm turbo "kit" project we undertook is finally nearing completion.  The build process has been documented on our blog and on the Supra forums by the owner of the car.   Here is the "kit"

blog done

I have kit in quotes because this is no kit.  It has been been created custom for our client.  This "kit" was custom fabricated in house by Alex Laventure.  He has spent over 70 hours creating this turbo setup for the client.  This setup was created to allow the continued usage of a TRD strut tower bar.  To accomplish this, the turbo was positioned lower in the engine bay.  To accomodate this positioning, a custom turbo manifold needed to be fabricated because one was not available.  The downpipe is 4 inches and currently has a reducer to fit with the current 3 inch exhaust.  The reducer will be removed at a later time once a 4 inch exhaust is fabricated. 

The car is now being reassembled and will be ready to tune by the end of the weekend.  Check back on Monday and enjoy your weekend.

Jason Oefelein and Gary Rayevich made the long drive to Evergreen Speedway to provide some track side support for Andrew Coomes and his LS powered S13.

Andrew Coomes in the pits

Jason Oefelein tuned Andrew's car in the pits to make sure he is ready to race this weekend.  This will be Andrew's first competition in his LS powered S13 so the practice session was used as a test and tune session also.

With the turbo manifold complete, fabrication continues on the rest of the setup.  Alex fabricated the down pipe.

The down pipe was fabricated from 4" tubing.


Fitting this large diameter down pipe in the cramped Supra engine bay was a challenge.  Alex managed to fit the down pipe in around the turbo manifold and Tial wastegate.

The cold side of the turbo also came back from being chromed.

A client of ours has an S2000 that we installed a GReddy turbo kit and tuned it on AEM.  This setup produced 333whp after tuning by Jason Oefelein. 

However, this much power was just not enough for our client.  He did some research and decided on a Mase Engineering turbo kit based on a Precision 5857 turbo.

The car is a Toyota Supra and the turbo setup includes a 71mm turbo.  This has been an on-going project for us.  The client came in with the goal of replacing his smaller turbo with a 71mm GTXR turbo and keeping this turbo below his strut tower bar.  This request required a custom turbo manifold.  The build process for this manifold has been a lot of long hours and waiting for parts.  Other factors that affected the turbo manifold was the use of a quick spool valve and a Tial wastegate.  The position of these also had to be taken into consideration.  Here is the end result.

Alex Laventure did a great job fabricating this turbo manifold to fit within the restrictions of the clients request.  This was a long process that has been documented throughout our blog.  The last parts that were finished up were the wastegate.  This large Tial wastegate needed to be positioned in a way to not interfere with anything else and still be able to dump into the exhaust.

From those two previous photos, you can see the path that the wastegate tubing travels.  The tube is routed between the 3 sets of cylinders.  The vband for the wastegate goes around the rear 3 exhaust tubes and ends below the turbo manifold.

Here are some detailed shots of the welds for the wastegate vband.

Continue you checking back for updates on this build.  Alex will continue this project by fabricating a down pipe and the intake piping.  We hope to have this car started and tuned with the next week or two.

Today, Jason Oefelein and Gary Rayevich accompanied Andrew Coomes and his team to South Sound Raceway to have a test and tune session with "White Apocalypse".  "White Apocalypse" is Coomes' LS2 powered S13 with the Rocket Bunny body kit.  This beast puts down 452whp and 413 ft-lbs of torque.

After driving up early this morning, Andrew was ready to begin drifting.  The 3 hour drive only built up Andrew's excitement even further.  We worked until midnight last night to fine tune the car for today's test and tune session.  The front end was modified to incorporate a bar around the lower part of the radiator.  This support will strengthen the front end and protect the raditator.  This support was also designed with points to jack the car up, thus making working on it easier. 

"White Apocalypse" is ready

After a final inspection, it was finally time to test "White Apocalypse" on the track.  Andrew was definitely up to the challenge.

Andrew began with donuts

To get a feel for the car, Andrew began the day by doing donuts.  The LS2 definitely has enough power to burn up the tires.  He was going around the cone and leaving white smoke behind him.  At times, "White Apocalypse" disappeared in the smoke, but the V8 was clearly audible. 

The aftermath of donuts

Once the smoke cleared, the power and control are evident from the donuts left on the track.  Andrew was able to easily keep the car moving around in closely concentric circles. 

After doing donuts for awhile, the real shakedown began.

The result of a day of drifting

After a long day of drifting, many of Andrew's tires looked like the one above.  "White Apocalypse" easily ate through many sets of tires.
