in car boost setup
Turbo Mini Forums

Finally got round to doing some work over xmas and decided to get my arse in gear, just a little confused on how to run an in car boost setup, i had a bleed valve before but surely just turning it in car is not a good idea. I aim to run about 10 psi on low boost and 15 or so on high, can i get the car rr'd on the 15 psi setting then decrease it to 10 or the other way round and would this run like crap? Spose i could go the mapped ignition route with 2 maps....

Rolling road tune the car to 15psi, then turn the boost down. This will make the car overfuel slightly but shouldn't be too bad.

There is no need for a different map moving between 10 and 15psi, as you use a MAP sensor, so the ECU will just look at a different part of the map once you have turned the boost up.

Surely apart from a bleed valve your only other option would be to fit some kind of bleed off solenoid like on the original metty turbos so at flick of a switch you go from 10 to 15 psi?

Whats going to break next!?

yes slim this is what i am planning to do, it is mentioned elsewhere how to do it, i think i will set the actuator to 10 psi then have a bleed valve after the solenoid dont know if this will work?

I see no reason why not its the same principle as the metty turbo to change boost from 4-4.5 psi to 7 psi

Whats going to break next!?

yes gav works a treat and easy to do just use your bleed valve to preset the extra boost if you use the switch and solenoid.

always looking for them bigger bunches of bannanas

Hi,
The Mad Max switchable boost sounds good to me. Can some artistic person knock up a piping diagram please?

well heres another way !

if you want to incorporate a solonoid valve

( i dont )

before the pressure switch there needs to be fitted a flow reg

disregard the non return valve

THERE are many ways!
to accomplish the same goal this is one................................

just a little input, if anyone wants to do diddys idea then i there is a solanoid that is on fords (i can find out more info if needed to what it is etc) and it just opens and closes on a switch.
i only know this becouse my (td) nova came with a dump vlave that barry fitted and it uses one fo these in line with the vacuum hose (becouse thos who know diesels will know theres no vacuum in the inlet to open it etc, but i wont go on about what i learnt about diesels here:)
