ImTheVoiceOfGod also tested these in the other Hood Spacers thread and found that they reduced his IAT's at the MAF by 20 degrees.It's entirely possible that the spacers allow for more airflow(and thus turbulence) to mix the warmer and cooler air thus bringing the temperature of the air in the area of the SRI up a few degrees.God job on the info though,but I say it's still inconclusive for everyone because the main benifit is'nt decreased IAT's but lower underhood temps overall.

"yeah, like I said, I don't think my data necessarily makes sense since at idle, I'm basically making the car more like an open hood which I definitely know dropped temps.

However, how much does underhood temps help your performance? I'm curious because isn't it, for the most part, your car's performance is about the intake temp since that's the only place the car's really using oxygen? I mean, I guess aside from the radiator or something. I know engines are supposed to be more efficient at 212 or something right? I just figure that it's best to have a warm engine but cool air (hence CAI).I can only say that it's better to have lower under hood temps then higher.i remember a test where they took the hood off of a new GTR and gained quite a bit of HP.Will we see the same results???Not likely but for anyone that is boosted I would expect a significant difference.

but seriously, I don't know. like I said, I really wanted to believe I broke a thread for a reason and wasted hours for a payoff. I actually didn't even think it was that ugly at all. I was ready to just leave it as is if I noticed ANY benefit."
Well, aside from the POSSIBLE entrance of rain I can see no reason not to keep it if someone had a CAI or had a way of directing incoming cool air back to the back of the engine bay.

but SLIGHTLY tilting the hood up you are not increasing drag by a measurable amount...Tuft testing has confirmed this for me.Think about it,at most you are changing the angle of the hood by MAYBE a half a degree,you are really increasing the frontal are enough to make a difference anyways.If aerodynamics are a concern take off mudflaps if you have them and/or build a flat belly pan.

I think its pointless. You car looks like it needs body work and you really dont get much of a difference to really achomplish anything. We own civics, not F1 cars.

To each their own...but there is measurable gains that have been posted in other threads as well as found by major magazines.And for the civics not F-1 cars then we should'nt do anything to our cars being that we will never be as fast as the almighty F-1 cars.:facepalm:

^Possibly,the more power a car makes the more heat it creates as well(Generally) and that means more heat that is possibly trapped under the hood.

 

[bossman]

I was referring to the complete removal of the hood as someone had stated.

oh..yeah,that's just retarded for a DD or anything but a show car.

 

[bossman]

not to mention that the type of intake may play a role due to where it gets it's supply of air.

The biggest thing I think people are forgetting is that temperatures under the hood are not uniform,at idle and definitely while the car is moving.SRI are more prone to suck up air with or without hood spacer because while there is not as many places for hot air to escape W/O spacers, there is bound to be more turbulence and mixing(with spacers) of what could be cooler air with warmer air due to this turbulence in the engine bay.this mixing raises the overall temp of the air in the vicinty of the filter on a SRI.Which is why CAI are less likely to experience this.Also.CAI are a little less likely to heatsaok due to the fact that they are constantly drawing in cooler air than what exists in the engine bay,which helps to cool the metal of the intake tube from the inside out.
