Adding a hood scoop?

[camopaint0707]

Would adding a hood scoop with the opening facing the windshield cause a significant decrease in MPG's? I have a 1995 acura integra that gets a pretty hot engine and wanted to add a scoop but not if it's gonna severely hurt my fuel economy.

There is probably an issue with the cooling system that should be dealt with first. Adding a hoodscoop would just be a bandaid.

agreed, might be better to get a coolant fush, or find out what's causing the high heat condition

Does it get higher then have way on the temp gauge?

No over heating issues. It just gets hot thats all. And I was planning to block off the front of the car for better aerodynamics but if a hood scoop hurts that then there isn't a point. Could I just get answers on the hood scoop question, not the car over heating question please.

In theory, I would think it would hurt your FE, as it would create a lower pressure going into your intake (because it's in a wake) Now, how much it would hurt I don't know. I've wondered myself about the benefits/drawbacks of a forward-facing hood scoop--it'll probably hurt aero but the ram air should help the engine. A rear-ward facing hood scoop would basically give you negative ram air I would think.

Look up "cowl induction". There is a high-pressure area at the base of the hood on most cars (AFAIK); a hood scoop facing rearward at the rear of the hood will take in air from that high pressure.

I have no idea how it will affect the aerodynamics of the vehicle, compared to a forward-facing scoop on the front of the hood or no scoop at all.

Check your coolant/radiator thermostat. I had to replace mine last year. It was stuck halfway open, leading to long warmups and then running hot once it was warmed up.

get some exhaust header wrap and wrap your exhaust. That will reduce under the hood temps a little.

Yes I'm aware of cowl induction but most of those are for performance. I just want a little cooler air into the engine. The air wouldn't even hit near the intake at all more like the top of the block. I would just like to know if or how bad it would mess up the aerodynamics.
