Looks Great mate!

How did you go with the holes from your orginal spoiler? Did you fill them? I wanted to do this as well to mine, however was told the lip spoiler wouldn't cover over the holes..

Have been looking at the Fibre Sports one instead, however really like the look of G6ET lip spoiler..

Looks good but that picture makes me wonder how the overboost valve works, you would think excess boost would go straight past it and into the engine on WOT.

Hey Dillz, the closer to throttle the better... it's set to leak off to atmosphere when things aren't right. My boost is set for 16psi, I'm guessing the overboost valve is set to open around 2psi over that. The ECU should correct boost, but I don't think it can react quick enough to situations like blowing a hole in cooler piping, splitting a rubber/clamp on pipes etc... doesn't take much to pop an engine when ECU thinks it's only using 5-7psi but the turbo is puffing at 25+psi to maintain a set manifold pressure, whatever it may be.

It's pretty much like a safety relief valve on a pressure vessel, a preset boost pressure will still go through the throttle and to engine (in my case 16psi)... it just has the mechanical protection of the overboost valve so if 19+psi occurs it will be relieved to atmosphere... if this happens I'd say some noise would be heard in the engine bay

G'day Ben, F6's have 9 holes (YES 9!!!!) in the boot lid, I'm pretty sure the Fibre Sports one only covers holes from XR6T's spoilers?

I am rocking a taped up boot lid at the moment, I will purchase a new lid with no holes and spray it up in the next few months...

building a house and renting at the moment, money is a little tight so can't really justify the boot just yet - it's killing me though cause I blaaaarrdy can't wait to get it on :(

Go the GT-E / G6E lip spoiler mate, you won't be disappointed

20psi would be nice Roof..

When I have some money sitting in the bank for a 'built engine' I will throw some additional boost into it for ya

nice.. what's the go with the overboost valve Roof.? do they work well mate.? I like the catch can to mate..

Mechanical protection aimed at stopping the engine from POPPING if she overboost's, believe they work well - cheap insurance!
