Bonnet vents - Page 3

they're not gonna hurt but they aren't needed on a track zs with a nasp kv6, for the money it would cost to have it done well , you could do a mod that would give you some actual gain.

It wasn't a 'practical' plan for the track car. I really like the look of properly done vents, not the stuck on look. Like the BTCC ones liked above. I think on the black ZS mk2 it might look good.

many of the old gen btcc had half height rads (think the mg was one of them) and the grille was used primarily for air to the plenum.
The overheating problems they had were on the start finish if there were delays, the car was not design to idle (at 3,000rpm) stationary.
But cooling wasn't an issue out on track due to velocity of air.

The ZS on the other hand is a road going vehicle designed to sit in traffic. Cooling should not really be an issue on a nasp car like ^^^ said.

Many people at the track lift the bonnets when they come in, I'm sure some do it only to show off the bling in the engine bay, but this will dissipate heat (and the ZS bonnet can catch fully upright), but a cooling down lap also helps with this and moreso the brakes.

I never lift the bonnet, even after an hour or two solid on track, perhaps I should, but the engine has always been OK.

Like you, I often run my car 3 people up with a car rest of 10mins per hour, it is a gruiler on the car but it takes it.

I really like that.....

Sorry, I prefer a more subtle louvre. Not a fan of that. Looks too 'stuck on'?!

Let's not forget some people want the looks and to be different and it not at all to do with gains. Not all of us are chasing seconds, it is more to do with having fun in a safe manner and keep our licences as clean as possible. Those that chase the times should be racing fulltime just like I did many years ago, it takes alot of money and alot of time, I gave up when my last child was born as I spent way too much time building, racing, maintaining and building again, it gets too much.
