Stupid Question Possibly

[Ben1720Cup]

Hi chaps,

I’m going to be running headlight-less next week on track for more airflow to the filter cause it’s going to be 20 degrees. Now I’m just wondering (stupid question coming up), will I have any issues with bonnet popping up? Has anyone else ran like this? Does the bonnet stay securely shut?

Oooosh. I'd get a headlight blank with an intake cowl on it if I were you. Apart from anything else, a fecking great hole like that is going to cause so much drag I can't believe it won't outweigh any slight heat soak loss.

No need to run it like that for 20 degrees.

I've ran mine in 30+ and it's fine.

I’ll give it a go and see if I notice any difference or just a placebo effect. Surely we should have no risks of the bonnet opening?

I'd be more concerned if something flew into the engine bay.

Get a blank as mentioned or as James says there's no need. Unless your going for track lap record?

I’ll give it a go and see. Hopefully the drag won’t be too much.

I don't think the bonnet will open the risk however is that you have an off and absolutely fill your bay with gravel/smash the snot out of your fuse box etc.

It won’t make any difference at 20 degrees whatsoever.

If the engine temps are getting too hot, it will be more likely you’ve been out too long more than anything.

I ran my old supercharged (standard block) in 30+ at Oulton and the temps were fine.

Any difference in performance will be so negligible it’s just not worth removing the light for tbh.

What power were you making?

What power were you making?

250bhp and 220 lb ft.

All the power

EDIT* you should read Cubs build thread, its actually an incredibly depressing read because the car was so amazing by the end that he sold it and has been driving a 1.6 Golf around for the past year (ignoring recent purchase which has made up for it).

Not true. I ran it supercharged for nearly 2 years and multiple track days.

Then in between clio and golf, there was;

- a fully loaded 3.0 V6 f-pace
- an S6 estate (4.0 twin turbo one).

But if Carlsberg made clios…. 😜

Quite.
