Looking good so far!

Interesting about the boost control/spike. Perhaps they aren't 16psi?

Seen many turbosmart ones say "X" and varied by a good 3-4psi when on the car.

Soo surprised it comes on at almost the same time as -7 size turbos, makes twin turbos look like junk

Loaded up on a dyno -5s and -7s basically "come on" at the same RPM on a dyno interestingly enough, yet they are a good 60-70rwkw different up top.

Drive them on the street however and its a different story that you don't get on paper - been there and done it with -9 to -5 :)

It depends on the pressure and also the piston location in the manifold. Apparently Turbosmart guarantee it will hold the stated boost due to countless hours of bullshit bullshit testing. Perhaps on their test jig, not in the 'real world'.

I am interested to see what my new 26psi springs turn out to hold. Hopefully I have time for a squirt tomorrow.

Gonna have a play with it in the morning :)

Yes gate pressure, i agree 100% about the springs. But i cbf'd changing them. Just made it a bit ah touchy tuning it as i cant work up from low boost.

Ash- no extra loading on my dyno it has a set 2second preload and i start all runs at the same speed. I agree with transient boost response on the road tho. Deano and i can test the rolling starts :) -5's vs 6262

yea paul, its all standard, its even the factory fuel lines, and rail just with id2k injectors and the plugs rewired. Oh his got cam gears on it.. but thats not out of the norm.....

    • Sounds good.  I don't 100% understand what your getting at here. When you say, "I keep seeing YouTube videos where people have new paint and primer land on the old clearcoat that isn't even dulled down" do you mean this - there is a panel with factory paint, without any prep work, they paint the entire panel with primer, then colour then clear?  If that's what you mean, sure it will "stick" for a year, 2 years, maybe 3 years? Who knows. But at some stage it will flake off and when it does it's going to come off in huge chunks and look horrific.  Of course read your technical data sheet for your paint, but generally speaking, you can apply primer to a scuffed/prepped clear coat. Generally speaking, I wouldn't do this. I would scuff/prep the clear and then lay colour then clear. Adding the primer to these steps just adds cost and time. It will stick to the clear coat provided it has been appropriately scuffed/prepped first.  When you say, "but the new paint is landing on the old clearcoat" I am imagining someone not masking up the car and just letting overspray go wherever it wants. Surely this isn't what you mean?  So I'll assume the following scenario - there is a small scratch. The person manages to somehow fill the scratch and now has a perfectly flat surface. They then spray colour and clear over this small masked off section of the car. Is this what you mean? If this is the case, yes the new paint will eventually flake off in X number of years time.  The easy solution is to scuff/prep all of the paint that hasn't been masked off in the repair area then lay the paint.  So you want to prep the surface, lay primer, then lay filler, then lay primer, then colour, then clear?  Life seems so much simpler if you prep, fill, primer, colour then clear.  There are very few reasons to go to bare metal. Chasing rust is a good example of why you'd go to bare metal.  A simple dent, there is no way in hell I'm going to bare metal for that repair. I've got enough on my plate without creating extra work for myself lol. 
    • Hi, Got the membership renewal email but haven't acted yet.  I need to change my address first. So if somebody can email me so I can change it that would be good.
