i reckon if the mesh didnt need to be there nissan would not have fitted it in the first place. car companys dont like to spend a extra cent when building cars so it must be there for a reason .personaly i think if anyone reckons there are big gains to be made by removing are kidding themselves

I've read the negative boost article and it makes a good point. They measured vacuum before and after the AFM and there was a fair difference, which became a smaller difference with the mesh removed. The manometer doesn't lie.

If there is gains to be had, it would probably only be had if you retuned the ECU to suit it. Next time someone gets their car dyno tuned, try with and without mesh see if it makes a difference.

curious..at such a high velocity, compressor spooling and such, do you still expect the flow to be laminar?

maybe closer to the wall...I think can be safely said that the flow is turbulent anyways....what does it matter if the mesh cuts the flow or not..

chances are the mesh are there to prevent larger particles going into the intake system stuffing up the turbo...

better the afm then the turbo..

      R32 Skyline Handbrake Question

      By GTSBoy · Posted

      That's f**ked up. I'd guess it's more likely that you have an entire S13 subframe in there. Does it still have HICAS mounting points? Seeing as it is quite possible that yours is the only such converted car in the world, you'll probably struggle to find someone who can tell you from direct experience. 'Twere I you, I'd be looking for 4 stud Skyline rear brakes and convert back. At a minimum. Preferably go find all the stuff you need to put it back to 5 stud (assuming you're happy to change wheels) and upgrade to some decent brakes. You don't even need much stock stuff. Don't need calipers or rotors, as you can go fully aftermarket. Just needs hubs and the other bits and bobs that are different to what you have now.

      R34 GTT idle problem

      By GTSBoy · Posted

      The engine has nothing to do with it. The physical space behind the headlight is the limiting factor. And the height. The height of the NS70 is the same as stock. So the clamp bar across the top goes on nice. The battery tray is big enough for it to sit on. The X is for extra capacity - it has even more lead in it than the non-X NS70. Heavy f**ker. But it's not a track car, so I will suffer a couple of extra kg. In the case of the R34, maybe the physical space there is not as deep (forward-backward, not up down). Hence why they say the 60 is the biggest. But I would never trust a catalogue to tell me what will fit. I have the car. I have the existing battery. I have the tape measure. I have the dimensions of all the available batteries. I find the biggest box that will go in. (With the right terminals in the right places, of course).

      R32 Skyline Handbrake Question

      By elinde · Posted

      Hello! I have been having a hard time finding the answer to this question… I have a R32 GTS-T Sedan than has been 4 lug swapped using S13 hubs, rotors, and brakes. The front has also been converted to S13 suspension.    When the swap was completed, the handbrake cables were never hooked up, as the S13 rear calipers are the “handbrake”, and not the typical drum on rotor that the R chassis are. Does anyone know handbrake cables that will work for this conversion? I’d like to not use a hydraulic handbrake and stick with the traditional cable style. My original thoughts were to go with S14 cables and try to make them work, since I’m pretty sure S13 cables will be too short.    Any help would be appreciated!

      I did some research, considering you have a neo engine, how is that battery compatible? I checked centuries website and super cheap and says it's not compatible. Only this full size one is. https://www.centurybatteries.com.au/products/ns60-mf

      Help Understand GTT Boost Setup

      No, lets be honest here. I went to Winton and did a track day, for all the mods and V8 power and craziness I posted up a time that a K24 stock motor Honda Accord can do on the same tyres (narrower, too) 250kw and learning how to drive the f**kin thing is the sweet spot.
