Lowering engine compartment temps
 

I have been thinking of ways to keep the engine compartment cooler, which in turn will help keep the engine cooler. Big temps are once again on the way here in Vegas. Was wondering if anybody had some suggestions. I have no issues, but am always trying to improve if I can. I have removed the lower cover, I know this helps keep the compartment free of dirt and may provide a little more under aero dynamics, but I also know how much heat it traps in and that bugs me. I have also removed the rear rubber seal by the windshield to let heat escape. I was thinking of lifting the rear portion of the hood by placing washers in between the hood and the hindge plate, although the sides of the hood will then be higher than the fenders. I dont want to cut any holes in my hood!

Would this offer any significant gains in terms of cooling? Not sure how I feel about the hood being above the fenders.

I’m puttin’ speed holes in my car...

Where did you get that hood and what was the cost?

instead of completely removing the under shroud, i suggest getting one of these.

Z Speed Performance Aluminum Under Shroud (do a search for them under vendors)

It's custom. Bought the hood vents from a vendor Carbon Signal (here on the forum) and had them molded in. All and all about $1k

Does this fit regular Z ,and Nismo?

frank, tehy make one for each model, regular and nismo.

they have a version for each

you beat me to it Dai. :D

The hood looks effen sweet.

That is Old School back in the 70s & 80s people did that. Don't know if the purpose was cooling the compartment or a trend.

Seibon sells a range of hoods with slots or vents in them. The one I like the most is:

SEIBON :: Hoods :: HD0910NS370-TS

Looks close to the one SPOHN has in that picture.

As for removing the undertray, I would imagine that would help somewhat, but heat does tend to rise. Removing the undertray might cause some nasty turbulence or something.
