I want to do something totally not stupid soon.
I recently drove the car to Huntington Beach on the 5 and 405 and got the opportunity to not only watch my hood bounce up and down like mad, which I'll fix soon, but also got to watch my temp gauge go nuts whenever traffic slowed down.
I don't have a clutch fan nor do I have an e-fan installed yet, so it wasn't as troubling as it could have been had I retained the stock cooling system, but since all the track days I do are at hot tracks, I'd like to get me some vents. The aerodynamic advantage of releasing engine compartment pressure is an added bonus.
I was thinking one 20x9.5 (17x6.5 louver opening, 5 slots) on each side of the hood bulge (Silvia front) and two 20x11.5 (17x8.5 louver opening, 5 slots) in the middle, or two 13.5x10.25 in the middle and a NACA to the boxed cold air intake. I don't want to overdo it, mostly because the vents are a little on the pricey side.
It looks like the DSG Maxi runs something like a 24x10 in the front and a smaller one over the turbo. Bill, where did you get that size vent?
Anyway, my question is where should I locate my hood vent/vents, and how big should they be? I have no turbo to cool.
