I did this same thing with my Jag, tested the Fahrenheit with a temp gun, same numbers. Get hood louvers/scoop. Way more effective. My intake temp went from 144 to 103.
On a vintage track Jaguar I saw that the entire Exhaust manifold and pipe under the bonnet had been wrapped in an effort to lower the temp. It must get hot under there.
Be interesting to see e fine temps when you are pulling hard. I only say that because fluid dynamics don’t quite work the way you think. Firstly the air will go from high pressure to low pressure areas to equalise. High pressure air is fast moving. Low pressure air is slow moving. So over the front of the bonnet you have very fast air and as it compacts up smashing into the screen is becomes high pressure air. I’ve even seen air being pulled down into the bonnet at speeds as the air in the engine slips under the firewall easier than the air passes over the screen. Secondly I bet you’d do better buying a couple of bonnet vents and placing them either side at the front. This will release the slow high pressure air from behind the rad as it hits the engine. Then the air will not only pass out of the grills much better Han the back lid of the hood but will free up the air behind the rad and allowing the air to flow through better and cool the engine better. Hays what I’d do anyway. Looks way more cool too.
Cool modification Bryan! I hadn't saw anyone do this for years! I looked at a 1967 Plymouth satellite 426 hemi car in a old garage back in 1980, the guy had the hood lifted in the back like that to clear the Rat roaster intake he had on it! Very cool mod! Thanks for bringing back the memory!👍
That hemi powered satellite must have been an amazing site to see. I had never seen anyone do that before the great race. Most that had a hood that could shimmed did, and it had a noticeable effect when we shimmed the 69 Chevelle.
This mod only improves the cooling at a standstill. It will actually reduce the cooling efficiency while driving at speed. The bottom of the windshield is a huge high pressure area. Which is exactly why every car uses that point as the intake for the AC/Cabin fans. Raising the hood back there will allow air to push in from the back of the engine bay and fight against the air flowing in through the radiator.
I thought this exact thing with a few of my rigs and it just wasn't an issue. The science sounds great, but my cruising Temps remained the same in 3 different vehicles
Hmmm I'm wondering if anyone has designed an automatic/dynamic, or valvetronic hood spacer design that when car is at idle, the hood raises to a certain height like in the video and when the car starts moving, it closes down to flushed stock height.
It's an interesting trick for cheap. My only concern is that if you blow a rad hose (or a hole in the engine) your going to get fluid all over the windshield. I have a better concept from something I ran into as a business owner/mechanic. A customer with a diesel truck who used it to tow boats across state came in for a power steering pump. I told him I'd get on it when it cooled down. He informed me it was cool enough to get started. I went out and checked, the engine was warm but not so hot I couldn't keep my hand on it. Every I/I boat has a blower to evacuate the air in the engine bay. If you look at an I/I boat you will see two scoops on the outside edge of the boat. One facing forward, one backwards. They come in all shapes and sizes. He had purchased two small chrome scoops and mounted them on his hood about 3/4 back. Driver side facing forward, passenger side backwards. This created a ram flow and allowed it to exit through the hood rather than out the bottom of the engine bay. The passenger side being mounted facing back meant anything unwanted coming out went on that side of the windshield and kept the driver side clear. Ever tried to see through an oil coated windshield?
Sorry that I was so harsh when the 318 was such a fail. You have shown that you really can build, and that UTG just pushed you under the bus. He is making click bait and you're making a monster. Bottle Rocket has nothing on this. Now do the same with the Satellite, and the Buick.
I saw a video of an experiment involving hood spacers And interesting enough it pulls in air rather than push out air when driving At a stand still it’s good at releasing heat but not so good when driving
Apples to apples with no other changes I got I am showing a significant temperature reduction with the sensors that I have inside my engine bay. But every car has different fluid dynamic properties
Vehicle airflow is something that is totally overlooked by most people. Build a good ram air intake setup and you can easily have 1psi of boost into your engine at highway speeds.
Hahaha no. You cannot generate even close to 1 psi of positive pressure inside a volume the size of any intake manifold, just by using "ram air". I'm happy to be proven wrong if you can provide documented evidence of that claim.
as I saw the hood pop in the back and you saying modding it like modding a video games that turns out getting glitch or freeze or lagging or crash just to realize that the mod need an update LOL.
This is great. I have the original 7m-ge version but it runs hot a lot. My question is did you remove the seal on the hood? Basically let more airflow thru? Also what kind of radiator? Id love to swap mine one day because its a super clean 1988 AZ car that was garage kept. It just lacks power. Ive seen the 1j/2j/1.5j swaps but the fact you went 1uz route makes me think of so much more. I know a guy that ls swapped his, so i need to find something thatll work for me. Have you done much weight reduction? I think theyre 4400lbs which is crazy heavy and im wondering what to do for now to at least get the best out of the 7m NA engine and help stopping distance too. Im happy youre doing so much to the mk3. I think theyre the best of the "wedge" cars and to get mine was a dream come true. Now the car guy in me just wants to work on building it up constantly. 😂
Always seen people do that but didn't think it would drop so much heat. Just watching the hood pop and seeing that v8 and supercharger peak out is pure ecstasy.
If you're an Ace Rewards member, you might've saved a few cents. And you might get a coupon for a few bucks off a purchase for your birthday (like I did recently). You really can't see the change unless you're looking for it...besides, you're going for cooling, not Concours😁👍
Couldn't you slot your hinge bolt holes and tweak the hinges a little? We used to use this material lycra spandex I believe. It would let air move but not so much snow an water. Could add some cool looking vents? Rivet them over the cowl sandwich that material in?
Spending the $34 is a whole lot better in my mind than mutilating the hood hinges. I am also not a fan of vents on the hood if the car can’t live in a garage. Also aftermarket vents that are riveted in look pretty sketchy
@@LunarOutlawsGarage we used to make ours out of thin aluminum. For the snowmobiles. That why we used the waterproof breathable material. Put them over the Cowell. Water can run right through there anyways.
We had that same problem with the 69 Chevelle on the great race. The full video will come out on Dylan‘s channel, but we used the shimmed hood, a pusher fan and Dylan came up with an idea using a power steering cooler for a fuel cooler. Even when it was 90° you can see condensation forming on the outside of the fuel line going into the Holley. I am going to be installing a fuel line cooler using AN fittings over the winter to help Drop the fuel temperature even more
Hey, don't mean to be a super creeper here lol but I saw a few road signs and obviously all your NY plates on your videos. I think we're local to each other! Love the content. If you watch my channel you'll see alot of 890 and rt 5...if that means nothing to you then I guess I'm wrong in my assessment. Love the videos!
"Do you mind if I smoke?" doesn't work as a smoking tire pun in Japanese, because in Japanese what you're literally saying is, "Is it okay if I inhale tobacco?"
@@LunarOutlawsGarage Destroyed every plastic piece under the hood, wiring harness, every cable (shift, accelerator, cruise control, etc) big fuel leak. Upper intake manifold and valve covers were ash, even roasted the battery, you could see the plates. Basically everything, must've been drenched in gasoline. I suspect a rat chewed through a fuel line or the fuel line popped off or burst.

I simply built some nice heat extractor vents placed in the low pressure area, works great and looks good.

You brought back old memories. Our city's Hemi hero had a 68 Charger, that was new at that time. Yip I'm that old ;O)
That hemi powered satellite must have been an amazing site to see. I had never seen anyone do that before the great race. Most that had a hood that could shimmed did, and it had a noticeable effect when we shimmed the 69 Chevelle.
This is a mod as important as taking weight out of the car. Great job its gonna help anyone that does this

Love the mod to keep that engine bay temp down . Worked a treat 🔧 🤙
Rotor boys trick for keepin them cool as we have reverse bonnets stock 😎

Tony is a toolbag. I unsubbed him long ago. Damn shame people act like that, but butt-holes are everywhere.
What did UTG say? Hahaha.
Well.... i now know what is on my docket to do this week
I saw a video of an experiment involving hood spacers
And interesting enough it pulls in air rather than push out air when driving

Apples to apples with no other changes I got I am showing a significant temperature reduction with the sensors that I have inside my engine bay. But every car has different fluid dynamic properties
When you drive the heat get sucked out from the engine bay
old school mod from the 90s that works well and is free
Vehicle airflow is something that is totally overlooked by most people. Build a good ram air intake setup and you can easily have 1psi of boost into your engine at highway speeds.
100% Air temperature and airflow dramatically change the performance of a car
Hahaha no. You cannot generate even close to 1 psi of positive pressure inside a volume the size of any intake manifold, just by using "ram air".

It was easier to make a video answering your questions. I hope this helps. #toyota #supra #shorts
cool trick to keep things cool
pun intended😜
Yup.. me2.. (JDM spacers)👍👍👍👍
Always seen people do that but didn't think it would drop so much heat. Just watching the hood pop and seeing that v8 and supercharger peak out is pure ecstasy.
Lol I open the hood just to look. I was only hoping for around a 10° difference in the fuel Temp so I’m pretty happy with this outcome.

Absolutely. I do end up getting coupons from them for my birthday and then I completely forget to bring it with me 😅
@@LunarOutlawsGarage I know that feeling. 🤷♂️😁
what about rainy days? how much water goes in?
That’s an excellent question. Joking aside, not that much. #automobile #supra #shorts

"Do you mind if I smoke?" doesn't work as a smoking tire pun in Japanese, because in Japanese what you're literally saying is, "Is it okay if I inhale tobacco?"
What software are you using?
For?
Nice little trick, Bryan!! I like it. Used to do that to my 69 Javelin😁😁. Cooler is better!
Peace my friend
Thanks Brian 🤙. All the little things add up
I got a bmw that could use this mod but unfortunately the hood opens backwards. I don’t think there’s nothin I can do about it
You can lift the hood lock then
What would happen if it rains will water go in thru gap??
Well excessive water?
Youre fine most electronics aren't in the back of the hood. That's all you need to worry about is fuses boxes and etc.
Thanks for sharing 👍
I should've done this on my Buick so the under hood fire would have been obvious.
How bad did the fire get
