Im looking at taking my car out to the track. right now i am performing the neccessary upgrades to ensure i can race.

I saw that i need to have a secondary bonnet restraint. What do you guys use?

I have a standard bonnet and i think i will look like a wanker if i put bonnet pins on it. Anyone got other suggestions?

Cheers

Does it state that its needed for a stock bonnet?

The OEM latch is unlikely to fail, and if it does, the safety catch is also unlikely to fail.. if you see it quick enough.

I wouldnt be worried about a secondary catch for an OEM bonnet. Unless it clearly states it IS required for an OEM bonnet too.

Iv been track racing for years, and the only people i know with pins are those with CF bonnets where the catch isnt bolted to anything structural, IE the fiberglass skeleton.

Also, out of the many many many days i have been to i have NEVER ever seen a bonnet come unlatched or fly open.

The odd muffler fall out the ass, fuel tank straps coming off and blown motors/boxes, even an engine mount bolt working loose and flying out under the car... :D but never a bonnet!

I've seen many carbon fibre bonnets come off actually. It's really hilarious to watch (not for the owner of the car though).

They often smash backwards and smash the roof and the windscreen. Sometimes they crack badly and bits of the bonnet flies off.

Most of the track days ive scrutineered, a secondary bonnet restraint is necessary. Lots of people hook an old belt from the bonnet frame and clip it down through the bumper or so. Another way is with a small chain and a shackle/caribbina and hook it onto the radiator support.

basically it depends on the Supplementary regulations for the event you are entering. If the Supp regs dont say anything you don't need a secondary restraint unless it is full on racing (schedule C requires secondary restraints for non road regstered cars)

Most events dont need a secondary restraint for modern cars

1 question though,

With using a belt or the clips etc, what if theres a fire under the bonnet?

Be a bit hard to get them undone in time?

mind you though if there is a fire Id be out quick smart! but if a small,little fire started?

Despite the dual catch system std on modern cars the track days we do with the WRX club here in Vic state you need one. There are lots of ways you can do this.....bonnent pins are fine with a std bonnent, others use a belt strap fitted to a suitable spot and I use a wire cable attached to the frame of my bonnent which hooks to the radiator support.

my advice is buy one of these babies. http://www.initialdrift.com.au/forums/view...074&start=0

cost about $25 and make sure you ask for it to be sheathed with the rubber heatshrink (stops it scratching up stuff). easy to fit, just need to drill a hole.

now that I've bought mine I just keep it in my helmet bag with licence and helmet etc so that I never forget to take it to a track day/sprint/whatever.

I'm surprised you need a secondary restraint for a skyline, its certainly not required in the CAMS regs (late model cars don't need an additional restraint). Unless it is requried by the supplementary regulations, I haven't seen them

Yeah some events now are starting to require them now even for late model cars. Up till now later model cars with an un-modified 2 stage factory catch have been ok, but for some reason of late it seems they are moving towards making all cars use a secondary restraint. Even a recent drift day I attended required all cars to have one and that is classed as a non-speed event!

Still for $25 and 5 mins drilling a hole it's not too onerous. :P

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Automatic Power Button Light Flashing

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
