Have just picked my car up from having a forged engine rebuild along with quite a few other bits,
gone from standard hawkeye sti power to being 400hp,
noticed on the way home it has a ticking/rattling noise scared me half to death thought it has broke after 10 miles but after plenty off looking round found it's the new Perrin 3 port that's clicking on low revs or constant of you rest your foot on the throttle.
anyone else had this issue??

 

I had an apexi boost solenoid in my old car, I could also hear it ticking, turned out to be cable tied to a bit of metal, I removed it and put a bit rubber under it and never heard it again. worth a shot

 

Yes they are noisy. The Apexi is equally noisy.

 

Might just be where it's placed then, you can't hear it outside but in the car it's rather loud

 

it shouldn't be ticking at idle as the car has no chance of making boost but depends how it's been mapped in. Normally i'll leave them at 0% duty at 0 throttle so they get some time off when they aren't needed. But as above if its anyway fixed to something solid (strut tower/strut brace/metal bracket etc.) you'll hear it ticking/clicking away all the time. Just space out with a bit of rubber like the standard one is and you'll be grand.

 

you could add rubber washers


i have profec and ticking too, but when i add rubber washers ticking was down

 

I was in a rush when I was fitting my SWRC 3 port on the day it was being mapped and bolted it straight to the strut tower with no rubber bush... next day when it was cold started, I though my engine was ****ed lol... it was the 3 port, I refitted it with rubber spacers etc and it 80% quieter... on very cold mornings you can still hear a bit of tapping on partial throttle until the engine warms up... noting on idle.
