MKII Boost Controllers for the Nissan Patrol!

The Dawes Devices Boost Controller for the Nissan Patrol

controls boost spikes and maintains EGTs (Exhaust Gas Temperatures) by providing a constant boost pressure. The new MKII is an improvement over the original Dawes Device and includes a stronger spring for higher boost, with a stainless steel ball, in a smaller package. Performance is the same as the original (other than ability to reach a higher pressure).

All domestic and INTERNATIONAL customers can now purchase directly from our online store, with FREE shipping up to 10lbs *

The Dawes Devices HYBRID Boost Controller for the Nissan Patrol

adds a synthetic, low mass ball, in place of the stainless steel ball. This improves the reaction time of the mechanism and reduces boost fluctuations in extreme off road conditions. The lower mass ball maintains contact with the ball seat, even if the vehicle is jarred. The HYBRID represents the ultimate in boost control for the Nissan Patrol.

Both versions come with the following:

2 feet of our premium silicone hose

five ty-raps for hose installation

extra tee for tapping existing vacuum lines

But don't just take our word for it; Read some reviews of the Dawes Device:

Very happy with performance. Have fitted to 2002 Nissan Patrol 3Lt Di and set to 16.5 pounds. Putting another vehicle on road and will buy again.

Here at my shop we convert Vanagons to Turbo Diesel engines. The Dawes Device makes using a reliable VNT turbo easy. Thanks!

Personally I am not a review writer however when the 3bar racing Dawes valves were fitted to our 2003 Nissan patrol 3.0 zd30 yep the grenade engine, wow what a difference not just only in overall performance the turbo boost was stablised it’s a different 4×4 now. I would think if company’s like Nissan ect take the time to utlise the expertise of the guys at 3 bar racing a lot problems can be avoided and build a relationship with 3bar racing with further tuning out of the factory. I hope to see 3 bar racing logos sitting beside nismo ect. Guys keep doing what you do.

Perfect device, inexpensive, easy to install and to adjust, works as expected even in harsh conditions (offroad rallies).

I have two Dawes Valves on my Nissan Patrol Common Rail Diesel. The first limits the boost pressure to 16 psi for normal running, I also use one, switched by a Dawes electric solenoid, that limits boost to 8 psi for long distance cruising, It saves me about 2 litres per 100KM!

The Dawes Boost Controller valve that we have fitted to my 02 3.0 lt Nissan Patrol wagon has removed all the over boosting issues we had and definatley saved the motor from self destruction I highly recomend a Dawes Boost Controler for this application

Driving a Nissan patrol with the ZD30 motor ( grenade) I fitted a Dawes manual boost controller and a needle valve. The Dawes device has enabled me to control my boost . I have had it fitted now for 4 years and have never needed to adjust it. Great service great device. Would recommend to anyone who needs to control their boost.
