Those look great!

I assume you were not running the oem ducting on the oem hood? Just a oem vent?

This is amazing!

This is awesome!

Should I run an open hood radiator exit, or are the cooling louvers better? Would adding a few aero spikes to the back of the roof, and raising the wing help? You may get more air to stick to the roof and you'll have cleaner flow to the wing.

Smoke through the radiator would have actually proved something….

Awesome work! Congratulations!

Can you share some more info about fan shrouds and their negative effects? Perhaps make a video about it showing with and without a shroud?

This is great info thank you. I've been looking to do a heat extractor for right behind my radiator on my 2015 Fiesta right in the middle of the hood.

The aerodynamics are amazing

cool

This may sound odd, but I am looking at putting as pair of split center vents on my 2010 Tahoe. It's not a race car, but when it is triple didget heat In the summer I would love to give the engine as much relief from the heat as it can get when we are running it all day for work. I will also take whatever aero advantages it can give me on the highway as well & hopefully some intake air cooling as well while rolling due to reduced heat soaking of the air box & intake pipe.

When it rains or snow does hood luovers actually potentially damage the engine?

The positive pressure on the ducted system will make the air more dense. Dense air cools better. Possibly negate the reduced air flow effect on cooling. Exhalent video, thanks.

Test was made with the radiator at working conditions temperature (so around 100°C) or ambient temperature?

Is it possible to make measurements of flatfloor and diffusors? This would be also interesting

Thanks man very helpful

Are those hood vent on top of the jeep hood?

Awesome, I was wondering about this for my Jeep .

I’ve got an e36 I’m about to redo the cooling system and track it one day. This is the exact video I was looking for thanks!

So what are the numbers?

Would adding a small fan operated oil cooler/transmission cooler behind a louver or a few of them provide additional cooling?

Was there a clear advantage over the carbon hood? Thank you for all the testing and data.

This is great! Thank you for this information

More smoke tests. I wanna see smoke going down an intercooler scoop with exhaust vents on either side

Cool! Pretty neat project! So in conclusion, the lower rear vent would be the most effective? Providing the most down force and less drag with the liners installed. Or i am reading the down force char inverse?

Why is there such a big difference between the mustang and the bmw regarding downforce, like the mustang makes more DF with a milder louver?

Can’t wait to try all of mine out. I’ve got your vents for the hood, front fenders and rear bumper

Really good job on this

This is now my favourite channel on youtube. All this testing data available online and for free?! Thank you so much!

could i cut the back of the hood from one side to the other? a definitive opening instead of lifting the rear. Or would it be better to just cut the central part?

where is the pdf? I didn't find it on the website. 8:23

The reason is created more drag was the disruption to the air flow over the roof and turbulent airflow on the windshield.

Just a suggestion: in future videos can you show windspeed and drag numbers in addition to DF? That would be very helpful. Thank you.

No smoke in front to see the suction and exhaust of the hood louvers?

Damn thanks to show the proper way to make holes in the bonnet 👌🏽

Great video, just found it. I have 1984 chevy caprice Ls swapped with Lm7 5.3 bored. 020 with LSA supercharger . Was thinking of adding vents to hood get rid of heat, any suggestions?? Thank For Your Help

I have a 61 bugeye street car with a sbc 383ci My underhood Temps are way too high. Looking to add hood louvers to extract radiator heat.. Hot Air flows into the air cleaner causing stumbling.

Did I miss reconnection of under hood bracing to skin after all cutting? or are some of the screws long, and catching brace (Under)hood?

I don't understand the advantage of this system. nascar and gt3 use this system, correct? Wouldn't a cowl induction be better? What's the advantage of air going up and not going through the engine?

Put them on the roof too

Do you guys make a drip tray for these vents by any chance? I daily my GT350 in Houston and would like the increased cooling these provide, but we tend to get some heavy rain here

Ok.

can you share tecnical data for this set up just like old videos if isnt private thanks

Great Video And Information... But I Hope You Can Improving An Audio... The Voice Is Too Slow... Only Can Hear In A Really Quiet Place... Thanks Boss... :)

@race louvers . Hi . 20mm Raise hood work for cooling ??? Thx
