I have tried to boost my stock gtst up to 12psi but the problem im getting is:

i plant my foot down and it reaches lets say around 10psi then when im close to 5000rpm it then jump up to the 12psi mark but it dosent make any difrence... im just using a simple T piece bleed valve... im thinking that the wastegate actuator isnt working properly or its not getting enought fuel...

did any1 ever have a similar problem? i was also thinking if using another type of bleed valve or boost controler but i dont think it would make a difrence... i took the T piece of and now running stock it also has the same problem reaches 5psi then on higher revs like 5000rpm it then jumps up to 7or8....

PLEASE HELP, thanks in advance

Thanks guys for the tip after finally disconnecting the stock boost controller, I am able to boost to 12PSI no probs.

One more thing the car drives really good now. Smoother. I reckon the boost controller (stock one) was holding back the boost and power!.

So disconnect that stock boost controller and your car will drive better and faster.

Cheers

    • I'll just leave this with, holy shit, those cars at work are awesome, and this will look wicked!
    • Could you modify this duct so instead it pushes the extra air through the radiator too and not down and out? For temps, I know it's not the greatest idea, but as a bit of a last resort, you could use a very intermittent misting spray onto the front of the coolers/rad. You don't want to be soaking them such that water is dripping off, but a small most on/off so that the water evaporates. That point of it constantly evaporating, rather than being soaked in water, will pull a LOT of heat out of the cooler. I'm literally thinking just the little mist sprayers for a garden from Bunnings. Being in a low humidity climate it will help even more! The other trick if you want to be ghetto is some shade cloth hung in the opening, and keep it wet. Pretty much now it's acting like an evap cooler on a house, but cooling the air you need to use to cool the radiator...   On a topic to think about too though, when air enters through the bumper, is it all nicely ducted from the edges of that opening back at a nice angle, or is it like most cars, and the edge of the opening just stops, and suddenly it's wayyy wider behind that? If it does the later, get it shrouded out at nice angles. When that opening changes too rapidly, it can actually cause a high pressure zone between the front bar and radiator, and limit air flow into that area, which means less air for cooling, as it effectively stalls the air, AND adds to drag...
    • Do you have any before and after photos? That's $200 just for the hydro blasting?
    • It doesn't look like there's a lot of options out there these days, and what's out there is performance oriented aftermarket stuff (with the GTR markup) I wonder if there are other cars with similar springs, after all its just a matter of length, diameter and stiffness. Alternatively, I did see coil spacers. Probably not the best option, but could be serviceable too.
