Thanks so much for all your content on under trays. Do you think once you increase down force or reduce lift underneath the car that braking will be reduced with all other things being equal? It seems like more grip would be available to the tires. Will be incorporating your ideas to better improve my 2013 Sonata which is already modified. Thanks again
Yes braking will be improved with less lift / more downforce. But... you must be braking to the onset of ABS / wheel locking, and the difference will be greatest at highest speed.
I have this question if I install an undertray am I gonna mess my cooling system? That air that passes through the radiator has to escape somewhere, I was thinking about getting one of those bonnet spacers
I’ve always wanted to do a full front to back undertray but I am concerned about using a material that is fairly light but robust enough to withstand the heat from the exhaust system. I also am concerned with sealing up the area underneath the engine bay because then where will all of the air that is pushed through the front heat exchangers going to go (without needing to vent my hood).
All covered in great detail in my latest book - www.amazon.com/Vehicle-Aerodynamics-Modification-Development-alternative/dp/B0C87VYVL8 or Amazon in your country.
Hi I have a Ford E450 van and it's engine is between the front seats. It gets hot do to the engine bay not being able to get the heat out of it. Will an undertray help? The bottom of the van is about 15 inches off the ground. Thanks, Jim
You really need to do some simple aero pressure measurements, as covered in my book. Otherwise, it's just guesswork. www.amazon.com/Vehicle-Aerodynamics-Modification-Development-alternative/dp/B0C87VYVL8 or Amazon in your country.
@@ianvital8834 I cover the modification of road cars, where you want low drag and low lift (or some downforce). Race cars typically go much faster around a track with huge drag and huge downforce. Ipso facto, race cars are not a good guide to the aerodynamic modification of road cars.
@@JulianEdgar thanks i'll look it up later. I'm currently practicing automotive design lookin how to reduce drag and generate downforce with out to much drag since my cars has less HP taking advantage on being light car.
I just hit 👍 before watching now. Thanks as always.
Much appreciated!
Thanks I used an example of this on my small SUV and noticed a marked difference. 4:54❤
Got your book today. Thanks.
Awesome! Thank you!

For most cars, the base of the windshield is a high pressure area so these hood spacers will most probably make air enter the engine bay
Thanks for this
Looking at these videos and finding a scion frs in the video, the very car im working on

You can use aluminium sheet or the cheaper aluminium composite panels.
If I had a Great British pound sterling for every version of a Porsche 911 rear wing... They can't all be right, surely?
Yes, they can all be right - different ways of doing things. Porsche aero is typically very, very good.

Can we discuss why some Sports Cars have recessed center sections of their roof?
Reduce projected frontal area and so drag.
How do I determine if my car (22 Subaru WRX) has attached airflow? Tape-and-yarn?
Yes
What u opinion the best position to put exhaust tip tail pipe at the back? Center or right or left of the car..
I've never seen any research on this and haven't done any myself. I doubt it matters.
If you look at late model truck they are basically in the bumper. They add a little air so it can make the wake a tiny bit smaller.
Would it be possible to make a video about techniques for dealing with the back end of an SUV-type vehicle?
I have some videos coming up that cover different car shapes.
@@JulianEdgar l’m sure I’m not the only one looking forward to those. Thank you
Time attack aero . the engineering guide on proper automotive aerodynamics.
No, not at all. Such cars would have massive drag - as nearly all race cars do.
@@JulianEdgar but there a way to increas speed and efficency? also with integrating proper aerodynamics also can improve acceleration right?
