Does This Look Normal?

[Ultimategtr]

I thought I would replace my 7psi actuator with a 10psi r32 one.. BUT.. look what I found when I took the heat shield off..

Could someone PLEASE confirm whether the flapper opens by this amount below, or is it being restricted by the heat sheild backing plate?

Closed?

Open?

backing plate for Heat shield

Thanks

They are not made to open up 90 degrees. perfectly normal.

Does it move more if you take the heat shield bracket off? Changing the dump flange thickness would then affect the opening angle.

As Stao said, its not critical as long as you don't get boost spiking at the top end.

Cheers for the replies so far guys. Appreciate the quick ones.

The turbo has ALWAYS crept up. Even when I was running the stock ecu, it would creep up from 7psi through to 15psi. Now its making 275kw @ 18psi with creep.

Its not the factory turbo btw, its a heavily moddified factory turbo running ht18 core with bigger wheels etc etc.

I can see the flapper hitting the backing plate. I have a feeling its restricting it.. I'll take it off, but 1 of the bolts is an allen key bolt with not much space for me to crack it open.. grr.

can you get a little grinder in there to take off a bit of the plate lol

[lulzsec]

would it have not been easier to just add a boost tee, as stated by hyper gear a waste gate will not always open perfect 90 degrees

So...ended up the bracket indeed was restricting the flapper.. Agreed that the flapper will not open 90 degree..but it fixed my prob.. It holds 10 psi through to around 6k in 2nd..which is how far I took it..before it would creep up to around 16 psi at the same rev.

Also put on an r32 actuator and now it's a different car. 1st gear is useless now.. 2nd breaks traction too but not as bad. Lol.

Feels like it's making way more power now. Now to fit my ebc..and get a retune to hit 300 hopefully...tune was made very rich due to creep.
