I have a focus rs, the boost was ran direct & peaked 10psi!

Ive now reconnected up the boost solenoid valve & its peaking abiut 1.2/3 bar & holding 1 bar.

Car has bluefin/superchips
Decat
Ss exhaust
K&n panel filter
Also has turbo technics turbo & am unsure if std or upgraded?

Anyway ive now brought a forge actuator with blue spring & was going to fit this & set up to run 22psi using boost solenoid?? Ive done a few searchs & seen every1 is running boost direct. Any reason for this??

Cheers

Keep the solenoid plumbed in mate or fit a boost controller.

Yer i would rather keep solenoid but was wondering if there was a reason why u couldnt?

Like maybe with blue spring actuator & solenoide it may boost over 22psi??

Spose theres 1 wat to find out, gonna fit scangauge & actuator & if boost us too much in lower gears ill fit a boost controller

It will boost to much in the higher gears not lower.

People run the yellow spring and solenoid to peak at 20 psi and hold a bar. This gives 270 bhp.

Run a blue spring and direct to get 22psi peak and hold around 20psi. This gives 300 ish bhp.
However Lu have no boost cut this method.

I'm running a blue spring and the solenoid. I peak hard mid range at about 23 psi. The held boost fluctuates quite a lot though. Cold days it will hold that. When the cars got it backs it off to a bar. This is the ecu cutting the boost back.

I wouldn't run direct with out a act gauge. Proper boost gauge and a uprated cooler ( either pre rad or front mount )

I had a std actuator running through the solenoid and was only getting 10 psi because it was shagged

My cousin runs his direct at 22 psi and it just melted 2 pistons due to over boost and he fuel pump getting weak. If he had the soleniod plumbed in it would have gone into boost cut rather than melt.
