May seem a silly question, but I don't know much about electronic boost controllers...is it worth getting one rather than using an amal valve? What are the advantages, and what can they do extra??

What ones would you suggest?

Cheers

 

far better boost control!specially if running high boost!i put twin air injectors on my sapp and had a pectal board fitted with adjustable boost control!brillaint mod!

 

I don't like the fact that if air injectors fail, you get unlimited boost

 

thats true but i think anyone with half a brain cell would realise something is wrong before it went bang lol!

 

Feel the rush lol

how much is a air injector set-up?

 

I don't know Doug, these things can happen very quickly!

Not worth doing a rebuild tho is it Steve

 

So true

One of the reasons im still on a amal valve

Im also too tight to pay for the air injector set up lol

Steve

 

Air injecots are about £250, but you can get boost controllers for similar money??

 

No idea, im too tight to do it

Steve

 

Great help

 

Pleased to have helped lol

Steve

 

 

air injector set up from scratch will cost around £450!thats including having the adjustable boost control

 

air injectors seldom fail they are fundamentally just a high flow fuel injector and I'd be more worried about a fuel injector fail and the resulting damage than the damge a failed air injector could cause.
most proper boost controllers use pneumatic shuttle valves and work by bleed on control as per air injectors and not bleed off as per amul valve

 

They are in actual fact a CNG injector, how they will cope under hard use etc I wouldn't like to say, nothing wrong with amal valve.

fitted a blitz duel sbc spec r controller to my saph, great bit of kit got 3 settings which can be set any any pacentage, realy easy to use / set up aswell, its very basic to some of the controllers on the market but it does all i need it to

 

an amul valve has a maximum frequency of 25htz and is ok for a standard car
air injectors are wrc
originally the bosh ones used back in the earlly 90's were designed by bosh for the turbo f1 cars
you cannot accurately control turbine shaft speed with a cheap plastic valve

 

mmm id rather trust my boost control on two very simple air injectors controlled by one computer than having a totally seperate from ECU computer (ie boost controller) controlling the boost through a single valve.

At least with air injectors youve got two of them (redundancy) and if the ecu goes tits up then the engine dies totally. Plus Id imagine if youve got a good ecu you could set up a LOS for when it detects a boost anomoly and keep things safe that way.

Where as with a boost controller if it goes tits up the engine pretty much carrys on as normal til it says byebye.
