Setting up a piper 285 and fueling for 22psi plus soft pedal info

[Billy91]

My car is due back some time in the next 2 weeks :D I'm just giving the garage the final info on what I want done. I'm having a piper 285 cam fitted and read somewhere it's best at 110deg. Also I'm looking at running around 22 psi boost what jets need adjusting to do this? And finally I want to do the soft pedal conversion is there anywhere that sells all the bits for this? Any help is much appreciated. Thanks

check 5teve L's threads theres a tutorial somewhere, depends on what turbo it is but id say something on the lines of

standard main 1.2mm
air corrector 0.9
2nd stage 1.3 to 1.4mm

but please make sure you up the boost slowly at points to see what the afr's are as there may not work for you matey

too lean on the afr will cause DEFINATE detonation

Ok thanks I'm unsure on the turbo think its a hks gtss turbo (waiting for the garage to confirm) I snapped a few aux belts before the car went in I read that putting the campus bottom belt pulley on can help? Is this true?

whats been mentioned above seems about right, although all set ups can respond different so defo keep an eye on them afr's and defo listen for det

you might also reqiure a 2mm needle valve or run an adjustable fpr to keep the carb bowl nice and juicy

Ok I'm still learning with all of this :) a 2mm needle valve? Is this easy to get? Is it advisable to fit the campus bottom pulley? I've got the anti jump pin but kept snapping belts :( anyone know what sort of bhp I'll be looking at?

200 - 210 @ Flywheel (T25 maybe a little more with a T28)

No need for the campus pully unless you need the extra clearance by pulling the alternator in a bit if you have a big FMIC.

Was told the turbo is a gt28rs turbo I also have the l&b and forge fmic
