FOZ STiV5

Hi all,

Just a quick one.

My STiV is running a panel filter and 3.5 inc exhaust from turbo back (no cats). It has the follwing boost characterisitics and I woundered if they sound ok.

1st, 2nd 3rd

On foot to floor...peak boost 1.2 Bar and it settles at 1.0 ~1.1 Bar.

4th

On foot to floor (70mph) 1.25 Bar and it settles at 1.0 ~ 1.1 Bar

5th gear (120mph) foot to floor 1.3~1.35 Bar and settles at 1.1 Bar

The 5th gear seems to pink (det) for a sec when it spools upto 1.35 Bar. Is this OK just for a sec and infrequently????

If I touch the peddle a fraction first at 120mph to get the boost going, the over shoot is smaller. Maybe 1.2 ~ 1.25Bar

Just wondered if this sounds normal...no det audible at less than 1.2Bar.

My motor is getting checked out this week...with close attention to the ECU.

I guess what I am asking is any amount of det..(pinking) OK provded it is for half a second e.g, I get it only after 110mph when floored in 5th.

Cheers all....

Foz,

hi mate! Just wondered how u know it is detting? I assume you are not monitoring it with a kocklink as you haven't specifically said so. I didn't think you could generally hear it inside the car and if you could then thats really bad. What symptoms do you feel when you think its detting?

Cheers

Paul,

I could hear it inside the car ...only at very high speed and for a fraction of a second....

Cheers

Have emailed you but suggest turn peak boost down with enlarged restrictor orifice as we discussed and get a Knocklink and things checked over fast - assuming your car has the same setup as mine which it looks like from your email.
