Gen III Turbo Kit

Introduction

Why Turbocharge your LS-1?  CAPA's testing to date has shown that a single turbo system gives LS-1 owners greater low down boost and torque than any positive displacement LS-1 kit that we have tested to date.  

With all Supercharger and Turbocharger kits there are compromises in every vehicle application.  Some engines and engine bays lend themselves towards using a valley type supercharger as they have no room on the sides of the engine while some engines are high, with little bonnet clearance but have plenty of room on the sides of the engine bay.  So it is really up to the kit manufacturer to build the best kit to suit the application.

CAPA have built a turbo kit specifically designed with low down grunt and great mid range power in mind.  This kit compliments our Vortech Supercharger Kits which create a more linear power delivery.

Some manufacturers in the marketplace have decided to adopt a twin turbo style system.  After developing our own twin turbo system, we decided it was not the way to go.

Having a single turbo system has it's advantages:

• The turbocharger oil drains into the sump and does not require an Oil scavenger pump.  Scavenger pump failure can cause damage to the turbos or engine (On a twin turbo system, oil is pumped to the sump due to the inability to drain oil from the turbos)
   
• Heat is easily ventilated from the engine bay.  On a twin turbo system, high heat from the turbos is evident at the foot wells, being positioned just in front of them.
  
• The turbo sits high in the engine bay, this prevents the possibility of the turbo becoming damaged by objects which could possibly pass under the vehicle.

About

Born of a need for LS1 Turbocharged performance the CAPA Intercooled Turbocharger kit uses latest technology state of the art turbocharger design and manufacturing principles to ensure both optimum torque and consistent durability over the lifetime of your vehicle 400kw of genuine turbocharged power and over 650Nm from 2200rpm – 5500rpm are available instantly with the CAPA turbo system at a twitch of the throttle. This is the CAPA secret, swift response, rapid acceleration, with all the benefits of excellent emission control, near stock fuel economy, and a torque curve unmatched by any other type of LS1 forced induction. Countless hours of engineering by a team of experienced engineers, tuners, and fabricators have gone into making CAPA's Turbo Kit a product that not only works superbly, and exactly as specified, but also one that has aesthetically attractive quality attributes. Bottom line is that that CAPA's Turbo Kit both looks, and works, great.

Quality

All CAPA turbocharger kits are manufactured to the highest quality levels. Heart of the system is a Garrett Ball Bearing Single turbocharger rated at 500kw maximum output. Being from one of the largest original equipment turbocharger manufacturers in the world, extreme durability is our guarantee. Fabricated parts of the manifold, such as the turbocharger manifolds and crossover assembly are fabricated from high temperature resistant stainless steel, all welded by qualified tradesman using the GTAW welding process. With a 'purge' weld finish to ensure no weld intrusion into the pipework, and then hand finished for maximum gasflow potential, faultless construction is guaranteed. Maximising charge air cooling without restricting system pressure is the CAPA intercooler system. Featuring cast end tanks, a high volume tube and fin core, with mandrel bent aluminium pipework light weight and excellent efficiency are guaranteed. Engine tuning is carried out using a custom written LS1 operating system, specifically written for the CAPA Intercooled Turbo Project by HP Tuners. A 2 bar (15psi) capable MAP sensor replaces the low pressure factory item, and allows us to map both fuel and ignition timing for every engine load and rev position. With the knock sensor fully active, and no airflow meter required, the tuning system is truly state of the art.

Stage 1 Kit Dyno Reports

Conservative dynamometer test and tuning has showed that our target power level of 350rwkw is achievable at just over 0.5bar boost pressure. Torque output is phenomenal with full boost, and massive torque available at the wheels using only a little over 2500rpm.

Power vs Torque

Stage 2 Kit Dyno Reports

This is the dyno graph of the Stage 2 Kit on a totally stock engine with 132,528km on board with the addition of Comp 918 valve springs and BP Ultimate 98 fuel. Seamless, massive grunt, with no tradeoff. Keep in mind this is the SMALLEST amount of power this kit will generate...which equates to around 680hp at the crank, and makes it a real fun drive on the street.

Power vs Boost

Q. Can I install a CAPA system on my standard engine?
A. Yes. CAPA's Gen III Turbo Kit is designed to me installed and run on a completely internally standard engine with only the addition of upgraded valve springs for additional durability.

Q. How does CAPA's Turbo Kit respond compared to a supercharger?
A. With careful turbocharger matching and selection we have achieved quicker boost response than is currently available from any other method of forced induction without critical air temperature, and hence efficiency losses. CAPA's Gen III Turbo Kit is supreme at making useable power straight off idle.

Q. When does my kit come on to boost?
A. Making boost low in the revs, hence optimising torque was a critical goal for us in the development stage of the CAPA turbocharger system. By 1800rpm 80% Of the total boost pressure is available resulting in massive torque gains at minimal engine speeds.

Q. How does CAPA's kit compare to other LS1 turbocharger kits?
A. Designed primarily for everyday road rather than competition use, CAPA's kit is optimised specifically daily driving. Its this focus which has allowed us to build a superior, and liveable turbocharger product.

Q. Will my fuel economy suffer?
A. Cruise fuel economy is 'as standard' with figures as good as 8l/100km registered at a steady 100km/h cruising speed. Obviously making full use of the available engine power will result in increased fuel consumption.

Q. What type of fuel does CAPA's turbocharger kit require?
A. The tuning of the kit has been optimised for 98 Octane Premium Unleaded fuel. Should this not be available though we would recommend 96 octane unleaded at a minimum. Sensing this the engine management system will automatically reduce engine power.

Q. Do I need to service my turbocharger equipped car more frequently?
A. While manufacturer servicing intervals are still totally acceptable we would recommend oil change intervals of 5000km due to potentially more exuberant driving conditions.

Q. Can I fit a CAPA turbocharger kit to my all wheel drive Adventra, Cross 8, or Coupe 4?
A. We looked into the all wheel drive segment carefully when designing the kit and have allowed the necessary clearance for the transfer case and all wheel drive system. Go for it!

Q. What potential problems should I expect with a CAPA turbocharger kit?
A. Frequent tyre replacement.

Q. How long does a CAPA turbocharger kit take to install and tune?
A. One of our trained installation centres (TBA) should be able to supply and fit your turbocharger kit within two working days.
