Evening all
Ive recently bought my first 996 turbo. It is an X50 manual with a stage one map. It is supposed to be running 550 bhp. The car also has turbosmart actuators which seem very stiff and seem to have quite a lot of pre load on them.
I was wondering what sort boost i should see on the digital boost gauge on the dash.
if i plant the throttle in 4th at about 3000 rpm the boost hits 1.2 briefly and seems to settle at 1.1 bar. A couple of times 1.3 flashed up then 1.2 and settles again 1.1. If I floor it in 6th ive seen it flick to 1.5 before dropping almost instantly to 1.2 then 1.1. but due to the speeds involved and the boost levels being higher than i'm comfortable seeing i let off quickly. The high boost number just flick up, they dont maintain it and they only appear when i stamp on the throttle, if build boost a little slower before flooring it the boost doesnt spike.
Im thinking that it might be due to the springs in the actuators being quite strong and too much preload meaning they take a split second longer to crack open?
i did buy a new N75 valve but not fitted it yet, i assume if that was faulty the boost wouldnt hold firm after the initial spike and would possibly be lower?
any advice or experience appreciated...
