FAQ

It delivers air to the engine cylinders instantly; the exhaust has an instant change in energy which drives the turbo. The turbo spools up quicker delivering boost, resulting in instant throttle response, instant torque, power, and more aggressive boost.

There are two sizes available: 47 & 60 Series. 47 series is a compact unit designed for smaller engines 1 – 2.5L. The 60 series is designed for the pod filter to fit over the valve. Suite’s larger engine sizes 2.5 – 6L.

Improved drivability and safety, instant torque, instant power enhanced “on tap performance”.

It changes the driving dynamics of the car, it is more responsive, lively, with instant power/torque with a seamless transition to boost.

Typically, no. Under normal driving conditions the valve does not operate. Valve only operates when you accelerate quickly.

No, the valve needs to be fitted by a qualified mechanic. After fitment mapping of the air/ fuel ratios is required.

No. The valve is only for petrol engines.

The valve can be installed anywhere between the outlet of the intercooler piping to the throttle body inlet. See installation manual for more information.

The valve can be linked into the intercooler outlet for cooler inlet air to the engine, but dust and moisture must be considered.

No, this is not recommended and voids the function of the valve

Yes, when the throttle is fully opened the valve produces a roaring sound. This is the sound of induction, like a naturally aspirated engine and lasts for a short period. When boost is achieved the valve closes.

Yes, when you add additional air additional fuel is required. See the installation manual for tuning guides.

See installation manual for tuning guide.

Yes, it is highly recommended this is a crucial part of tuning. The O2 sensors feedback provides instant AFR’s when setting up the valve. See installation manual for reference.

Yes, the ECU needs to see the additional air.

Ensuring the AFR (air/fuel ratios) are correct is vitally important for tunning purposes. ECU (electronic control unit) vary in architecture. Some Cars see this additional air and compensate. See installation manual for guidelines.

No, boost is always set by the wastegate. The valve allows the engine to breathe, introducing as much air as needed pre throttle to the engine the turbo spools up faster giving you instant torque/power, more aggressive boost.

No. The valve only operates under pre- boost conditions to deliver additional air to the engine cylinders.

Yes. You need to ensure the air/fuel ratios are correct. Refer to the installation manual as a guide to the valve AFR (air/fuel ratio) @ 105 KPA.

Yes. Depending on your requirements. The additional valve will add a smaller gain to achieve optimal 105 kpa at full throttle.

The turbo spool valve is suited to on/off throttle conditions. When the engine is at high RPM the throttle is closed, the manifold is under high vacuum, boosted air is dumped instantly to keep the turbo spinning. Once back on the throttle, the turbo spool valve opens instantly delivering air to the cylinder instantaneously, the exhaust has an instant change in energy which drives the compressor. There is no delay to the delivered cylinder air. The compressor spins up and delivers boost, the transition between atmospheric pressure to boost is seamless.

The turbo spool valve has undergone extreme testing. It was developed and tested to open and close faster than 0.15 of a second.

That is dependant on your engine configuration, engine configurations vary significantly. Set-up on a ls1 5.7 litre engine with twin turbos T04E and very short exhaust manifolds, with two 60 series valves fitted the boost is virtually instant. No power lag.

It is the buyer’s responsibility to maintain and service the filter, this is to prevent dirt from entering the valve and the engine.

The remote air filter kit is a great way to keep incoming air cool. Especially for engine bays with limited space.

No. As dirt will enter your engine and will contaminate the valve reducing life span. This will also void the warranty.

Yes. It ensures the air is clean and has no effect on the operation of the valve.

No this will destroy the valve and void the warranty. The valve is designed for air only.

No. Lubrication is not required and will void the warranty.

If you have linked into the air filter used in the 4wd and it is a sealed connection and watertight this may be ok.

Please Note: The valve is not designed to be submerged in or under water doing will void the warranty.

The valve operates up to 100 degrees Celsius, but it is recommended to keep it cool to reduce air intake temperatures.

No. The valve is self-managing and needs no additional plumbing

The valve responds very fast to vacuum conditions, there may be a small advantage.

No. The valve only responds to vacuum conditions. Not applicable.

It is always the buyer’s discretion when modifying a car in any way. The operating of the turbo spool valve is not harsh. It simply lets additional air to the engine pre boost to add additional off boost performance and improve the turbo spool up.

The turbo spool valve was developed over 3 years ago, undergoing vigorous development and on road testing. The product has been tested to over 1,100,000 cycles with various leak testing under high-pressure conditions. Endurance testing has demonstrated the valves’ reliability and durability which is paramount for longevity.

No. A blow off valve is designed to relieve pressure. The turbo spool valve is the opposite. It is designed to allow air to enter if there is a vacuum state.
