Option 1: The Blow off valve kit consists of a high capacity blow off valve that reject the excess pressure to the outside of the charges tubes and eliminates the turbo surge and prevents turbo parts deterioration. The result is a more constant and easy to modulate power, an highly efficient trail sled for any Precision EFI Flash or stock 900 ACE Turbo. This kit is completely bolt-on, you don't have to cut or modify anything in your engine bay. With this kit you will hear the sound of the blow off valve very frequently and with a high ''Whoosh'' sound.

 

 

Option 2: Charges tubes with Blow Off valve kit consists of a complete new set of charges tubes with new air intake tube with blow off valve port. Precision EFI charges tubes are perfect for stock sled and for high boost sled. This kit is completely bolt-on and you don't have to do any modification to your sled. Compare to the Standard Blow off valve kit you will have a better throttle response, a more moderate and less aggressive ''Whoosh'' sound and a nice racing look in your engine bay.  

 

 

 

 

**Turbo surge is not good for any turbo. Snowmobiles run a good amount of boost on a very small turbo, snowmobiles run always at high rpm, in cruise and in acceleration and snowmobiles have a lot of fluctuation of pressure in the charge tubes because we make many '"on and off" throttle opening. These conditions do have the potential to cause greatly accelerated turbo bearing wear and/or damage to the compressor wheel. The add of a blow off valve is the best way to prevent this situation.
