Well given you are melbourne, no.

The defects you will attract are not really worth the grief.

I mean yes the less you weigh the faster you go, but don't think by changing a bonnet you'll suddenly be even 5% faster. You'd have to remove 100KG's+ to really feel a difference IMO.

As for vents - do you have current cooling issues?

Vents help with cooling, however the dynamics of high/low pressure area's I've never really dug into

ive been looking for a carbon fibre OEM style bonnet (so i can spray it the colour of my car) for my 33 for AGES. problem is the most common ones have vents in them.

some american car club did a test on a nissan sentra a few years back to get it from complete stock (16s 1/4 mile) to see how fast it would go with all its weight stripped off. from memory it ended up doing around 12s after removing every panel and part that wasnt needed which included chopping the roof.

I had this idea a while back as well. It sounds like a great idea although the biggest problem is being a skyline you'll most likely be pulled over anyway "for the sake of it". As soon as they pop the bonnet they will see underneath and it will be pretty obvious that it isn't standard. Would be a fantastic idea in a true sleeper that will pass by unnoticed in the first place.

i dont think they'd really notice. i'd spray the inside of the bonnet anyway, they would just have to notice the reo on the underside of the bonnet isnt there - most (if not all) wont pick up on that.

I'd agree.

I think the 15-20odd kg you will save for a cost of $1500 on a 1400-1500kg car is not money well spent.

If you took 20kg out of a 700kg S1 lotus elise that might be a different story.

If its a GTR forget it, the bonnet is aluminium anyway and you are paying a fortune to save a few kg. The boot, spoiler and all hinges weigh a bit though.

    • 1. Factory knock sensors for now, honestly the RB26 OEM knock sensors seem ok as they're flat response instead of resonant type but they appear to be internally grounded to the block. If I do replace the sensor it would just be to get ones that are not internally grounded so a differential input can be used to reject common mode noise. Definitely plan on fixing this as a part of the tuning process. 2. Never deliberately induced knock, though I guess I could try that experiment if I really wanted to. 3. All of this is basically on a stock engine + ECU, only modification is HKS GTIII-SS turbos and a Nismo plenum. Currently I run it with the wastegate solenoid unplugged so it won't try to raise boost past wastegate pressure.
    • After being peer-pressured into paying $100 for the MW remakes, got BO6 on XBox Game Pass. I think that's worth it.
    • That's a given!  Bit hard to powdercoat it properly without removing them! 😁
    • No detail on compressor or turbine sizes, which doesn't help with housing size selection with that kit. However, from SR20DET mucking about and money torching perspective, a GTX2860R Gen 2 w/ 0.64 (46mm inducer) will do ~260kW on E85 about 1.5bar of boost. All in before 3000pm, which cause a gearbox to shatter. Now imagine the same turbo, on a modern motor with an extra 0.5L of displacement, and heaps of cam timing adjustability (not an on/off affair like the Nissan shit boxes). If this was my car (which I would never own or consider buying, ever!), I would go for a nice twin scroll setup, and a G30-660. Gates plumbed back, no silly shit. Lean on the cam timing, big displacement to create a flat-ish torque curve.
