Bonnet Vents

Recommended Posts

i am building a cold air box in my 32gtst and was considering the option of a bonnet vent instead of feeding air through the front bar, would this mean i would have problems in rain ? was thinking out putting an R34 GTR V spec II vent on

gunna photoshop some pics to see how it looks but cant find any decent pics of the real thing :ninja:

anyways yeh, would water gt on my pod, and this would be bad right ?

Rain is gonna get in what ever you do if driving in bad weather.

I'd go front bar vent...

1. Build a rain trap in the induction pipe.

Straight pipe tee'd or Y'd off to the air box,

dead end the straight bit of pipe about 6 inches awat from the T or Y

Water is heavier so wil carry straight on the easiest path.....i(e) the dead end.

It will hit the dead end,so put a small hiole in the dead end at the bottom edge to drain water away, via a drain pipe/ tube or just leave the hole to draining away to outside the body obviously

job done....

...some water bourne air will still carry on in to the airbox, cant be helped...bit like cheap water injection...LOL

2 or just plug the air inlet pipe in bad weather, and take the lid off your air box.....your not going to be road racing in really bad weather anyway.

The Hood Vent looks very cool

But it is in turbulent air...as it hits the grill and lights air curls over the front and is not ram air style as the Front Bar would be,

The hood vent would need to be further back to avoid the turbulence IMO

it may not get as much as a ram air fed system.

it still gets alot of airflow through that vent.. the airbox will seal against the bonnet and a custom pipe is going to be made that feeds air straight to my turbo's. as i dont need my AFM's anymore.. it is trial and error at the moment but i think it will be sufficiant.. gives quite an induction noise thats for sure...

*edit* yes water gets in if it rains...

    • I still have Garrett parts to build GTX2860 if interested. 
    • I reckon coilpacks too. Mine went at exactly 100,000kms
    • In the process of riding up my car lol, am trying to get a decent looking oil cap. Some say they are fine to fit all RBs or even all Nissan, others like a stock GTR oil cap say rb20/25/26 but they won't fit a neo rb25. Is this due to the stock plastic engine cover or is there something else different?
    • Well Coolant pressure increased significantly under + boost.  Enough to bypass rad cap Coolant pressure normal under low load conditions and no overheating. Head off and you can see where it was bypassing the cylinder ring to coolant chamber on both head and gasket. Head cracked tested and serviced, all good. Block was only visually inspected, so please god ...  let that be ok   You could argue that is a Head gasket failure but it was still very much a complete unbroken gasket. So suggests some stretch on the factory head bolts. I know others that have had the same as above and not even taken the head off, just put in studs and  continued on for years.  
    • Just jumping into this one, someone's decided to try get into my 34 by bending that top door window trim back.  Anyone know how to remove these? Going to try and bend it back properly and sikaflex it... Cheers
