Jason tuning "White Apocalypse"

Andrew Coomes' LS2 powered S13, dubbed "White Apocalypse", finished up dyno tuning today.  Andrew will have 452 whp and 413 ft-lbs of torque to work with on the track. 

blog dyno-tuning-done-template-452-413

This LS2 setup produces more power than his previous turbo SR20 setup.  Not only is there a substantial increase in power and torque, but the reliability will also be there.  Being naturally aspirated, the turbo is taken out of the equation.  The torque curve with this V8 is perfect for drifting.  It produces torque at low rpms because it does not rely on a turbo spooling up first.  Andrew will have more than enough power to get his car going sideways.  Look for him at Evergreen Speedway as he competes in the Evergreen Drift ProAm Championship this year.  The next event will be July 9th and 10th.

After the strong push to finish Andrew Coomes' drift car last week, we continue to working a different projects.  One of which also includes an LS engine.

Snapshot of the shop

The cars are in various stages of work.  Some cars are getting parts installed, while others have having things fixed.  Some are here for service and tuning, while others are having engine swaps.  We are currently working on imports and domestics, along with a car that is both.

Nissan 350Z engine bay with an LS1

The Nissan 350Z that is sitting on the rack is having a LS1 installed.  This Chevy small block is replacing the VQ35, a 3.5L V6 from Nissan.  This swap will increase horsepower and torque, and will also give this import the sound of a muscle car.

Engine bay of an S2000

In the bay next to this LS1 powered 350Z , sits a turbo S2000 that is having a larger turbo system installed.  The smaller GReddy turbo kit is being replaced by a larger Mase Engineering turbo kit based around a Precision 5857 turbo.

You can also see two Corvettes being worked on.  The red one is a C2 Corvette.  We are currently working on the carb setup and will soon be tuning it on the dyno.  We will be sure to post up a video of this Corvette when it makes it onto our dyno.  Like the C2, the C6 Corvette in the background will also be tuned.  It currently has a ProCharger installed.  Before we begin tuning it, we will be doing a full service and installing a heads up display.

Not pictured in the first photo is what is going on in the fab shop and the dyno room.  Currently in the fab shop is another Toyota Supra.  This one is having a custom turbo manifold fabricated to accommodate the lower positioning of the turbo below the strut tower bar.

In the dyno room, sits "White Apocalypse", Andrew Coomes' LS2 powered S13.  This car is an unbelievable car.  We are currently tuning it and will be uploading a video of it soon.

Like most parts on a car, a clutch wears out over time and needs to be replaced.  Our client's clutch needed to be replaced in his Pontiac GTO.  So for a replacement, we got him a Monster Clutches Level 1 performance clutch kit.

We also opted for the 28 lbs billet flywheel.

While installing the new clutch, we also installed a short shifter.

This past Friday, June 25, was the Evergreen Drift Pro-Am Competition.

Andrew Coomes debuted his LS2 powered Rocket Bunny S13.  To get his car ready, we put in over 250 man-hours in the past 3 days.   Andrew and his crew helped out whenever possible.

 Putting in over 15 hour work days for the past 3 days, we are excited to have Andrew's drift car ready to test and compete.  Andrew and his crew, accompanied by Jason Oefelein and Gary Rayevich, left for Monroe, WA.  They are heading to Evergreen Speedway for a day of testing and tuning.  This is Andrew's first time driving his LS2 powered S13.  In previous competitions, Andrew was driving a SR powered S13.  The new LS2 setup has many improvements over the old setup. Work on the front end continued with the addition of supports for the front fenders, bumper, and headlights.

The issue of the shifter position has been solved.  The issue was that the TKO transmission does not match up exactly to the 240 shifter hole.  To solve this issue, a Hurst shifter was modified to allow the shifter to come up through the original shifter boot.  The shifter position was moved back about 6 inches.  Along with the shifter, the hydro e-brake was also installed.

 Very early Thursday morning, the engine was started for the first time.

After a long day and night of work, Andrew Coomes' drift car is coming along.  We will push even harder to get the car ready for the track today.  Our deadline is to have it ready to go by tonight because tomorrow will be a test and tune day, and a day to let Andrew practice with his new LS2 powered S13. 

The front end needed to be fabricated because the original one was not up to our standards.  We needed one that would be able to support the new radiator.  The front end also needed to be changed because a large radiator would be replacing the radiator and intercooler combination used with the turbo SR setup.

We are pushing hard to finish AJC's new drift car for the upcoming Evergreen Drift Pro-Am event on June 25th.  Our goal is to have the car running by the end of today. 

As of  this past weekend, there was a lot of work to do.  The LS2 currently sits in the engine bay, but has yet to be wired since some front end fabrication is currently taking place. 

LS2 sits on Sikky engine mounts.

While Gary and Alex work on the front end, Mark is working on the wiring and dash.

Fabrication on the radiator and fan supports are continuing. 

We also are currently working on a transmission and shifter solution.  We have a TKO transmission hooked up to the LS2 however the shifter location does not match the 240's stock location.  The new driveline we recieved will also have to be modified to make it work.  We are using a 5-speed transmission as opposed to the 6-speed transmission that is normally mated to the LS2. 

Check back later today to see the progress of Andrew Coomes' LS2 powered 240 drift car.

 2008 Corvette Z06 on dyno at PSI 2

A client came into to PSI to have his 2008 Corvette Z06 modified into a high horsepower street car.  He did not want to go the on the path of forced induction.  He requested that we produce more power, while keeping the engine naturally aspirated. 

A stock Z06's LS7 is rated for 505 hp at the crank.  This particular Z06 had American Racing headers and a Billy Boat exhaust, which helped it put down 469 whp and 446 ft-lbs of torque. 

These are both very respectable numbers for an naturally aspirated engine.  However, the owner wanted more power.  We started by having the heads CNC ported and milled. 

CNC ported and milled head.

We also chose to upgrade the cam to an aggressive one. 

Upgraded very aggressive cam.

Upgrading to this cam required many supporting parts.  Most of the valvetrain needed to be upgraded to match this aggressive cam.  The lifters, push rods, and exhaust valves were also upgraded.  The stock push rods were upgraded to ones made by Manley, while the exhaust valves were upgraded to Ferrea ones.  The rocker ratio needed to be changed to accomodate the new cam.  This adjustment was achieved with a Comp Cam trunion upgrade kit.  ARP head studs were also used during reassembly.

The fuel system was also upgraded to match the more aggressive cam.  A FAST billet fuel rail was used to deliver more fuel to the ID 700cc injectors.  These upgrades allow more fuel to reach the combustion chamber.  Along with the FAST fuel rail, a FAST LSXR intake manifold was also added.  The intake manifold was designed to allow air to flow more efficiently.

LS7 in a 2008 Corvette Z06

With all these performance upgrades, we also upgraded the clutch to match. We installed a Monster Clutches Level 3 kit with a billet lightweight flywheel. The lightweight flywheel weighs in at only 18 lbs. This upgraded clutch will be able to easily hold the power put out by this LS7. 

Without a proper tune, we would not get the full potential out of these upgrades.  EFI Live was used to retune this Z06 to not only ensure the engine is safe, but to get all the power out of this new setup. 

It is now time to see how this Z06 performs with these performance upgrades. Following is a video clip of this Z06 on our dyno.

It put down 591 whp and 523 ft-lbs of torque.

After working on a custom exhaust for a K20 powered EG hatch, fabrication continues on the large single turbo Supra project.  This project required a lot of custom fabrication work to meet the needs of the owner.

The Supra project required a custom turbo manifold because of not only the large size of the turbo, but because of the location.  The owner requested that the turbo be positioned lower to accomodate the TRD strut tower bar he currently utilizes.

The lack of available turbo manifolds for mounting this size turbo in this location required a custom manifold to be fabricated.

blog most of turbo manifold

Most of the turbo manifold is complete.  The piping needs to be matched up to the piping that extends from the head.  For the proper fitment, the turbo, manifold, and wastegate have to be positioned in the car.  This is the tricky part because of the close confines of the engine bay. 

blog test fit

This photo shows how low the turbo will be sitting.  This lower position, below the strut tower bar, limits the space for the turbo manifold and wastegate.

The Tial wastegate used for this new setup is substantially larger. 

Check back for more on this turbo setup and installation.  Custom fabrication takes time, but in the end, the wait will be worth it.
