Why not just cut out every other one and keep a factory and correct period look to it.

 

 

No i will not do anything to that grill, looks nice with the chrome and after i have seen so many fake grilles-vents in other cars (modern one) i decide to leave it as is.

 

The cold air goes low so the lower part of the bumper concerns me, i wonder if i have any gains make it "more through" for the incoming air.

Surely you need to do more research about where the cooling air can enter and engine bay hot air can go when your car is going slow or stationary in city traffic, at lower speeds when climbing mountain roads, in hot summer weather.

I've even seen some flow simulations that showed that grill can actually take some air away from the radiator, due to low pressure area on the bonnet edge ( probably reason why the newer Škodas have top portion of the grill blocked out)

In the UK you can buy time in a wind tunnel for testing, I've known of someone who has done this but he was writing a book, no doubt now you could get the car mapped for computer simulations but nothing beats real world testing to be sure.  You can buy sensors for heat and airflow and place them in various locations on the car and record real world circumstances.  Of course this takes time, effort, patience and careful recording of the results and all the variables.  As you are only really interested in heat over summer you only need to do this over summer perhaps starting in late spring and going on to early autumn to be sure.  Then how will this affect your winter warming worries about getting the engine warmed as quickly as possible.

 

Even the experts in this area employed by the car manufacturers make mistakes despite all the time and development facilities they have at their disposal but you don't have the marketing and sales regions environments worry of the car manufacturers.

This only in laboratories.

An amateur like me can make some simple tests with a powerful fan and an anemometer but even this demands space (a repair garage with no other cars or a backyard not affected by the wind).

No it's not, you drive the car with sensors located, this is real world testing specific to your car and the circumstances it is driven in.

 

Tests do not have to be complicated just thorough.

Yes but only a car company's RD can do this.

An every day driver does this (it's for his filter, not the radiator):

An everyday driver can not do this simulation-measurements.

Not so, anyone that wants to can, not to the same level of expertise but can find improvement or not to a specific requirement, then it would be best to check if any improvement in one area is not to the detriment of something else important.

 

You've been altering things on your car going back years without an R+D department to help you.

No and you don't need to, you have your real car, which you can drive in your real world circumstances and take measurements and recordings like you do with oil and coolant, TC6, this gauge, that gauge, recorded figures from this way and that way.  This is the same just using different measuring and recording instruments.  You will not accept anything until you have tested it, so you need to do tests.  Try this, try that see what is better, no difference or worse.  It's what the R=D companies do and the racers.  Theory is all well and good but the real world has no concept of theories only testing can sort things, even after computer programs have already "sorted" things, drive a much more modern car and you will soon discover this.

Yes but down there what can i do?

2019 Aston Martin Vantage front grille.

 

 

NO WAY !
