RaceSpec Hood Vent Install (Page 2/2) Raydar SEP 01, 04:31 PM quote Originally posted by Spadesluck: Lol, you are very consistent. If I had to do it again I would move it back some. However it does serve a purpose still. My 3 row radiator, bigger fan, and this hood vent the fan rarely ever comes on even in 100 degree heat. Here's a question... With all of that hot air that is blowing out through that vent... Have you noticed any poorer performance from your A/C system? It seems like the air blowing back would be at least 100 F above ambient. A lot of it will be diluted, but some of it should certainly find its way down through the cowl vents. I've thought about doing a similar vent, but comfort is an issue, too. I've only had my car run "warm" (but not overheat) on one occasion. That was at ~75 MPH on a 100 degree day, so its not imperative... Thanks! Spadesluck SEP 01, 05:57 PM quote Originally posted by Raydar: Here's a question...

Never really gave that any thought, but I have not read about anyone mentioning it affecting their AC performance. I know many others have done similar setups to help with the underside pressure. I really doubt that air is making it back into the car though honestly. Raydar if you are concerned about heat, honestly the best investment would be a 3 row radiator and new fan. Raydar SEP 01, 06:18 PM Cool! Thanks for the info. Much appreciated.
