Hello,

 

was wondering if anyone had put an overboost button on their car, allowing for a few moments of extra boost. I'm not talking of NOS here, just a bit more pressure like the twin turbo John Cooper Works MINI (please.. don't take the piss... was just reading an article on pistonheads)

Not sure of a buttom as such, but you can set this up on most good boost controllers.

 

However, the problem is that most people are running at the cars maximum within a safety margin. It's not ideal to exceed that safety margin.

 

I.e. if you have standard injects and tubs, but have induction, chip and zorst you can push up to about 14.5 PSI max. Most people would just leave it on 14.5 psi.

 

Going above safetly levels is not good for the car and doesn't really give you that much gain compared to the damage it may cause.

 

Hope this makes sense.

Most boost controllers have an overboost button option.

to be honest, i was thinking it was a gimmicky in that - why wouldn't you already have it tuned to maximum anyways?

 

alas, cheers.

Its not so ideal for a car with stock turbos and injectors, but if you had larger items you would be more inclined to have a low, high and overtake boost setting.
