Dont know if you have seen it, but we did some testing that would give you a decent baseline https://www.jlwranglerforums.com/forum/threads/totl-innovation-h-e-r-o-hood-performance-testing-results-temperature-cooling-measurements.125807/

Function stays the same. The hood will evacuate engine bay heat and direct cool air to your intake.

I think we will try to run an Ike test this summer if possible

The sensors were placed at critical points (ECU and fuse box) as well as on top of the engine dead center to get an average engine bay temp. Heat rises so it makes sense to have as much venting as possible on the top side of the engine bay to help that otherwise trapped heat escape. None of our...

Where in Colorado are you? You are saying you have a Jeep you can 100% put into limp mode doing some sort of "normal" driving or you just stress it until it does?

I just went back and looked at our logs. For idle and crawl tests, the engine oil hovered between 214-219 for both hoods. Coolant tempt hovered between 218-220 but once the fan was on for the 35 mph test, there was an average 8 degree drop in coolant temp and 6 degree drop in oil temp when...

The ask isnt terrible. Getting the right environment on the other hand... We are in Colorado. There really isnt a day that doesnt have a wild swing in temps or any wind. Also finding a road with little traffic these days is just as difficult. We were brain storming and maybe when the weather...

We didnt focus much on the factory side vents. Looking back at the images, they certainly seem hotter in the factory hood photos so yes it does appear as if less heat is escaping through those vents but the overall temperatures drop running our H.E.R.O. Hood which is the objective. We dont...

Hood is primed so it will need sanding for paint. For wrap, I would probably still say a fine scuff is required.

It will do nothing to get below the factory specified operation temperatures but that isnt what is causing issues. The issue is what to do when those temps exceed factory cooling capacity putting the Jeep into limp mode etc... Anything to help get heat out of the engine bay and get cooler...

Cruising speed might not have been the best name for it. Should have just called it a 35 mph test. The output of the dyno fan as measured at the front of the Jeep was only 35 mph so we didnt run a test where the simulated vehicle speed didnt match the air that we were pushing at it. We didnt...

Coolant temp is unaffected in our testing. Factory programming is designed to run at an optimal coolant temp and nothing external is going to affect the Jeep from trying to reach that specified temperature.

We just posted up some test results of our H.E.R.O. Hood using a 20 turbo as our test mule that might be of some interest here: https://totlinnovations.com/h-e-r-o-hood-performance-testing/

It took entirely too long but performance testing is done. You can find a write up on our site https://totlinnovations.com/h-e-r-o-hood-performance-testing/ and we have started a thread here for discussion...

CRUISING SPEED TEST The purpose of this test was to simulate what happens when you are out driving on the street. Even with 35 mph, the H.E.R.O. Hood continues to deliver a reduction in under hood temperatures FACTORY TOTL DIFFERENCE Fuse Box Temp (°F) 169.17 151.48 17.69...

CRAWL TEST The purpose of this test was to try to simulate what is happening when you are out wheeling your Jeep. We ran the Jeep at 10 mph without the dyno fan running to simulate a slow crawl with little to no airflow to help the factory cooling system. This is similar to the previous test...

IDLE TEST The first test we wanted to perform was a Jeep sitting at idle. We wanted to see what is happening in the engine bay without any sort of external factors so the dyno fan was not running. This would be similar to a real world traffic at a stand still type of scenario. We also wanted to...

TEST SETUP To begin each test, we let the Jeep idle until we noticed all 3 of our temperature sensors had reached a consistent temperature. At the point, we considered the engine bay to be at its saturated operating temperature and an equal starting point for each test. We would like to note...

TEST EQUIPMENT For these tests, we loaded a bone stock 2024 Jeep Wrangler 2.0 turbo 4 cylinder on a load bearing hub dyno made by DYNOmite. By doing so, we were able to conduct all the tests in a controlled environment and were able to load the Jeep (provide resistance at the axles) to...

I know we have been promising some real test results on the benefits of our JL/JT H.E.R.O. Hood for quite some time not and we are very sorry it has taken this long but without further ado: For those that just want to know the results, here they are: Average 25+ degree drop in engine bay...
