Re: aerodynamics and cooling (mellowhead)
stock cooling system works surprisely well, even on the track.
i doubt you need more extra cooling anything other than FI
just my thought
bump for you for some numbers

Re: aerodynamics and cooling (mellowhead)
the point of getting a vented hood is to allow the hot air to escape the engine bay.... our cars are known to get heat soak.. and a vented hood will help prevent that...

aluminum rad actually increases the heat in the engine bay ... but it cools the water fast .. hence metal is good conductor to heat

Aluminum dissipates heat better through convection. Using it along with a vented hood, it helps cooling while the car is moving. On a dyno, it won't help as much, if at all.

exactly , therefore it increses the heat in the engine bay
... think about it, when the rad dissipates the heat, the heat goes to the engine bay ... and i also said it helps cool down the water fast

Re: aerodynamics and cooling (FR-MOB: s2slow)
i know a couple guys with aftermarket headers and the heatshields wont fit anymore. heatsoak is a bitch for them, so vented hoods=the win. when i get my new header ill definetly be looking into one.

Unless you're exceeding the cooling capacity of the stock radiator, there's no need to replace it.
Unless you've completely sealed off the area in front of the radiator, the radiator cooling plates are not necessary.
Vented hoods help with cooling but will only help cooling at speed. To prevent heat soak idling in traffic, by passing the coolant lines to the throttle body helps as well as running an intake manifold gasket other than the stock piece.
Last I recall when someone did some temp testing with vented vs. non vented hoods, underhood temps were 30 degrees cooler with the vented hood.

hondata makes an intake manifold gasket. helps lower temperatures of air entering the throttle body.

np but my beef with the hondata gasket is it leaks and squishes down when you torque it to spec. Not made of the best material but I guess it works.

Header wraps work, they're just fiberglass cloth that you soak in water and literally wrap each pipe with. Downside is you can shorten the life of the headers since they will run at a higher temp (not being able to dissipate heat). They make header wraps that you simply throw over the primaries like a blanket. These are commonly used on turbo housings. IMO, the best solution is getting the headers sprayed with a thermal coating.
