Don't you remove the side window fairing? Because they create air resistance ...

I cut the rear ones to reduce the drag they create. It’s nice having them for when it rains, I’m not devoted yet to remove them

Makes me wonder how the lower weight of those wheels could effectively decrease rolling resistence.

I made some more progress on the car the other day. Nothing new efficiency related but I got some paint work done and wrapped my mirror delete blanks for a nicer look overall. I’ll likely leave the hood in primer until the hood vent holes are cut in but it looks much nicer with more red on it and all the white coroplast covered up

Made some more progress on the car. Hood vents are half done and some preliminary testing done. So far it’s looking promising. Today we had ambient temps in the upper fifties (not quite ideal but not bad) and I had IATs near 70F. On the flatter stretches of freeway at 60mph indicated (63-64 actual) I was holding steady between 25 and 25.5% engine load, almost 2100RPM, and instant mileage jumping around between 51 and 53mpg. I still haven’t installed all of the hood vents (which help massively with heat soak) and I’ve yet to install smooth covers on my new wheels, and I still have a splitter/front belly pan to install. I venture to say it’s coming along nicely!

Lookin' good!

I like hood vents myself.

I'm convinced that my batteries, belts, hoses and other heat-damageable things last longer when the intense engine bay heat is allowed to escape up and out of the engine bay.

In fact, I've installed hood louvers on my Mazda, Jeep and F250. I've measured the under-hood temps, and the louvers do allow the heat to dissipate much better and faster than a solid hood top.

Relative to fuel mileage, I have found the louvers do not affect that for better or for worse. But I am (obviously) convinced the vents are well worth the effort in other ways.

For those who like to keep the engine bay warmer in wintertime, it's no problem to keep the heat in by attaching a sheet of aluminum from underneath, using the same studs that hold the vents in place on the hood.

Related to heat dissipation, my coolant temps have been about the same as always. Switching bumpers has totally deleted any kind of upper grille opening but has made a usable lower grille opening, with the total area coming in about 10% less than my previous setup with an unblocked upper and a 80% blocked lower grille. What I am definitely noticing though, is less heat soak, manifest in lower IAT temps after brief periods of sitting. It makes sense given that one of my current vents is directly above the airbox. I drove the other day with ambient temps around 40F, and while the hood surface was ice cold, there was heat pouring out of the vents. I’m hoping that since the other vents I have marked are closer to the radiator, I’ll see a change in coolant temperature (and hopefully more drag reduction) when I finish my hood

Unless there is a problem that causes the radiator cooling system to max out with the thermostat fully open at all times, I doubt venting the hood will make a difference in coolant temperatures. At least, they don't for me.

In my vehicles, none of which have grill blocks because in my semi-tropical climate I often need all the cooling I can get, the coolant temperatures are regulated by the thermostat at an optimal operational level. The addition of hood louvers have not changed that at all for me, and I really didn't want it to because temperatures below optimal can cause other operational difficulties, including a potential hit on fuel mileage.

I'm also not so sure to which extent a vented hood would effectively enhance the cooling, even though it might occasionally lead to an easier air flow which may actually increase the heat dissipation from the cylinder head.

Got some more progress done on the car today. Other than driving it and not being able to log efficiency due to the evap issue I have finally started on the rear aero. I started with the rear lip and passenger side filler panel from a Saab 9-3 Linear and made holes with a hole saw to help with the parachute effect until I make a full underfloor
