BLITZ SUPER SOUND BLOW OFF VALVE BR 70649

Item: BLITZ SUPER SOUND BLOW OFF VALVE BR FOR TOYOTA Celica ST205 (3S-GTE) 2/94-8/99 70649 (type: Release)

SUPER SOUND BLOW OFF VALVE BR

Uses a high quality aluminum die cast body. The clearance is optimized by high-precision CNC machining to realize smooth piston operation with good response.

The piston is coated with a defric coating to improve corrosion resistance and demonstrate outstanding lubrication performance even in tight clearances.

Uses black special coating resistant to corrosion and red alumite. Ideal for dressing up the engine room.

By replacing the flange shape of the mounting part and the size of the funnel with those of the conventional product, it is possible to replace the existing model.

Select a spring of appropriate strength for your vehicle type. Prevents idling problems that often occur with blow-off valves.

Succeeded in increasing the flow velocity by 17% by reviewing the venturi shape of the funnel part. Achieve a sharper and more powerful open sound.

A return hose can be attached by removing the Venturi funnel and replacing it with an attachment pipe. (Excluding some models)

What is Release Type?

"Release type" is a type that releases the boost pressure that flows backward when the accelerator is off to the atmosphere.

By adopting the fully renewed "Venturi Funnel", the powerful open sound that is well-established throughout the series makes the driving scene even more racy.

You can purchase a separate "return parts kit" and change the screw type Venturi funnel and return pipe to "return type", and you can return it to the suction side like the genuine recirculation valve. I will.

*Some models do not have the "Return Parts Kit" set. Please see the compatibility table by vehicle type .

What is Return Type?

The "return type" is a type in which the boost pressure that flows backward when the accelerator is off is returned to the suction side through a hose, just like the genuine product.

Since air after supercharging is returned to the suction like the genuine recirculation valve, there is no problem during vehicle inspection.

It is possible to respond to high boost pressure, which is difficult with a genuine recirculation valve, change the hardness of the spring, and open/close the valve with high response.

In addition, the powerful body shape creates a racey inside the engine room.

You can easily change to the "release type" that is open to the atmosphere simply by replacing it with the attached screw type "Venturi funnel".

*Some vehicles cannot be used as "release type". For details, please see the compatibility table by vehicle type .
