Testing The Verus Hood Scoop Block Off Plate
Вставка
- Опубліковано 5 лют 2025
- so I bought the Verus hood scoop block of plate with the hopes of lowering my manifold temperature. Verus advertises that this block of plate will help with cooling. Let's try to test that theory.

I should mention that I did make my fender vents functional a while back and have slotted fender shrouds that may change the results a bit compared to a car without that but if you look towards the end of the video you can see real graphed results from my tuner.
maybe hood vent may have a different airflow characteristic then the side vent where the block off may help possibly.. of course another test will confirm this if it conducted.
@@itsjohnnypanda2448 I have considered some hood Vents but can't bring myself to do it lol
Who would want to block that iconic hood scoop anyways?! Thanks for the video to show that there is some gimmicky mods out there
Its for the Engine to run cooler because you have no hot air in the engine bay with the scoop block off
@@Franknorm1337 fresh air enters through the hood scoop thus cooling off the engine not just the Intercooler. Front mount is not a positive mod for these cars. Air also enters the lower bumper no matter what and to take away the air entering the scoop will def reduce efficiency. It’s easy to determine this on simple engineering. This mod is to reduce the amount of lift on the vehicle with the air pushing up on the hood. If you have a front mount Intercooler I could see this helping a little. I don’t get why someone would do that. The top mount IC is very efficient and clever. If you don’t track your car and care about the ms off lap times then keep the top mount.
It's not a gimmicky mod though.. it's actually more functional with a vented hood
Nice video. I have a. ETS 4inch fmic and koyo radiator. Verus hood scoop block off and verus hood vents.
And I've been tuned multiple times by Ron on E85. After this video, I'm gonna remove the block off. I've had nothing but positive experiences with Ron and trust his data 100%.
2016 wrx, all the mods, running flawlessly.
Keep up the solid content bro!
Excellent video man. I think that adding the block off plate, in combination with hood Louvers will reduce manifold temps and coolant temps. Adding hood louvers is the key to suck air out and draw it through the front intercooler/radiator. The block off plate should help reduce the high pressure coming in to allow the hood louvers to work more efficiently. In summary the block off plate needs hood louvers to fully benefit over all cooling efficiency.
Thanks for the interesting results! Radiators and intercoolers work because there is a pressure differential across the core and Subarus have very little ducting and sealing around them. If we want improvements that's probably the place the start.
It’s trial and error with all these mods, and thank you for the $$$ sacrifice to put the community in the know sir! Awesome video!
For sure! And of course! I'm sure theres people that will have different opinions or results but there's not much info on these so I wanted to contribute my opinion and experience!
@@StreetInspired1 thanks man!!
So I think this is more for a non turbo car then a turbo, I want to get the hood scoop hood for my 2022 impreza for the look and honestly this block off would work well with it, but I would rather it have the air ramp off the top of the scoop not go in to a block like that, they have hood scoop deletes as well
It's not meant to keep your intake temps down. It's meant to keep your radiator temps down. By removing the inflow from the top mount, your radiator has less flow issues to fight against and can cool better. I've noticed an almost 8-10F lower with the plate than without it.
I wasn't looking at the intake Temp because thats completely enclosed. I was watching the manifold Temp. If the plate allowed more flow through the Radiator, it would also allow more flow through the front mount resulting in lower manifold Temps. But I didn't notice lower manifold or coolant Temps. When it's below 80° it's never really an issue but on the hotter days I just wanted a remedy to help with Temps but really can't see the benefits. Maybe because I already have Functional Fender Vents it doesn't really make a difference but I'm not sure.
I bought the scoop for aero dynamics. The open scoop acts like a parachute I think... idk about cooling stuff
I thought the benefit of the block off comes once you make vents on your hood, no?
Yup, Smeedia has a good video on this
i know this video is old but the purpose of the scoop block off is more to keep air from pushing under the car and lifting it up sorta like a parachute effect. still interesting to see the numbers behind it but the main point is aerodynamics not necessarily cooling
This is directly from. The manufacturer: "The Verus Engineering Hood Scoop Block-Off was developed to improve the aerodynamics and cooling of your Subaru WRX or STI. By blocking off the scoop, the owner is able to reduce under-hood pressure. This underhood pressure causes lift as well as decreases airflow through the cooling stack such as a front mount intercooler and radiator, hurting cooling efficiency" so I totally understand the aero benefits. I ended up keeping this on solely to help with the aero and keep the hood from "shaking " while driving from the pressure.
Definitely not a waste of money if you don’t run a top mount or an oil cooler in that location. It will help the air flow through your front mount an radiator since there is no turbulence.
Well that's the claim but I can't see any noticeable difference in manifold Temp (which would be the air after it has made it out of the Intercooler) or any difference in coolant temp. I'm probably going to leave it on regardless just to plug the empty hole until I eventually get an oil cooler.
Don’t believe that’s accurate. How will blocking it help with it flowing to a front mount? Air will still hit the upper scoop. Snake oil
@@CGNLEvolved it helps air flow because without a top mount the air isn’t directed anymore and causes turbulence in the engine bay. With it blocked the air that passes through the front mount and radiator doesn’t become hindered by that turbulence. There is many videos using smoke machines showing the difference with an without.
@@FunTimeWithSouls being in the game for numerous years; that turbulence in engine bay etc is not really much an affect on a street car. Just like putting a wing on the street when the wing affective mph downforce doesn’t kick in until over 100mph. Just be careful with gimmicks when it comes to “turbulence”
I tried it on my sti and it was a waste of money. Had it on my car for a week. Intake temperatures were 10 degrees higher.
Let me get this straight I’m gonna put a plate in front of the air scoop and not expect it to get hotter and run better. Come on man
Hey that's their claim. I never really bought it but wanted to block it off from the elements so I got it and wanted to test their claim. The hood scoop is there for the top mount Intercooler. Once you switch to a front mount the hood scoop really doesn't have a purpose. The idea or so they claim is that the scoop without an intercooler there will allow air in under the hood and cause turbulance and positive pressure to build up and make it harder for air to move through the cooling stack. And that adding the plate will stop that unregulated air from coming in and more air will get through the front mount intercooler and radiator and thus have a cooler intake charge. However after seeing my tuners analysis of it makes more sense. The air is actually going behind the engine and in turn should create negative pressure or in a way a suction pulling the air from the front of the engine compartment backwards so you would think it would pull more air with the scoop open. No one has actually ran any real data tests to prove these claims aside from my tuner running 3rd gear data logs and seeing little change but slightly hotter with the block off which is what I am observing in this video.
that is literally the point lol. it stops the negative pressure drop from right behind the hoodscoop....
running a little lean sir.
It is a little lean on my agressive map. Tuner probably does it to squeeze a little more power out of it. The heat doesn't help either. I try not to get on it much when it's this hot out lol
@@StreetInspired1 you scaring me lol
@@TheSibster86 I'm scaring myself haha on these hotter days I really should stick to my conservative map 😅
@@TheSibster86 😂
Bahahaha you wanna know why there no difference it’s because there’s no hood vents that’s the point now your just slowing the air down because it has nowhere to go in your engine bay the hood vents are made to pull the air out maybe you should do a little research first lol
@@dreambiggarage think of all the cars that come factory with front mount intercoolers. There's almost never hood Vents on those cars. There's no difference because the open hood scoop doesn't cause issues with the flow of a front mount like people claim.
@@StreetInspired1 that’s because there designed that way there is another ways for the air to get out usually once you start getting into areo like proper you’ll start to figure this out
@dreambiggarage all cars have open front ends though to allow air through the Radiator. Along with the wrx. But either way, if the hood was vented the difference would be so negligible for a daily driven street car.
@@StreetInspired1 I’ve personally tested this on my 2015 sti like two years ago not only did I see consistent iat drop 5 degrees my csf rad/oil cooler also worked better car ran 2 degrees colder
@dreambiggarage your hood was vented and scoop blocked with those results? Was the difference in temp comparing open scoop vs block off and Vents? That's a mathematical difference but 5° on one day probably isn't noticeable.
