Default Headers/upipe/spool/pops and bangs question

genrally.....
how would ported standerd headers and a zerosports 60/50/60mm (vortex thingybob) uppipe affect spool and the turbos boost limit

the boost was set on my car via a dawse device before
the engine was blew up

now it has been ran in properlly i opened it up for the first time today and noticed the max boost had dropped a bit, although it "seams" like it comes in a hell of a lot harder


it has been a long time scince i floored my car (well over 2 months) so the surge i felt can not really be measured, although i felt my stomach kinda curl up a bit (like when you get scared lol)

the car also pops and bangs a hell of a lot more now, i head previous threads which would suggest that the dawse device without a drilled bleed hole would show this more, but it was popping and banging on throttle lift off running actuator preasure only

i do not have a VTA chav horn
i do have a TAS adjustable piston type recirc valve fitted (standerd 97wrx one was doing the moo cow thing )

thoughts?

Thumbs up

the car seams ****loads faster TBH

i gave it a full throttle roundabout exit on the way home from work and i thought the thing was going to lift its front wheels of the ground
i dont even know how high i revved it, i was to busy thinking "****"

i had "thought" that the car was faster but was not sure
after seeing how much the back end dropped, now i am very sure
did a quick check and it was fueling to 895mv on full boost so the fueling is fine

no knock retard was noticed but i was busy keeping an eye on the road
i have locked it up fopr the night, i know that if i go out tonight and try to get used to it i WILL end up in trouble, either by crashing or with the police

will set off for work early tomorrow when the roads are quiet and do a few more tests, it just seams like its pretty much the same up the revs till it comes on boost, and then it just revs like buggery

1st thing that i thought about was "this gearbox is going to blow up"

the fueling is fine

the ignition advance is fine
i think it might be the recirc dumpvalve?

no idea who ported the headers, i bought them from "welloilbefooked" for the small sum of £25 and got the zerosports uppipe thrown in for free, cheers mate
