Ahhhhh finally, rear disc brakes, real positraction and an 8.5"
We had record temps here last summer...115*. I didn't have any problems cooling. I really do recommend getting your manifolds ceramic coated, and some VHT ceramic exhaust primer and ceramic paint for the rest of the exhaust system. A cowl hood isn't going to let any heat escape unless you're at a stop. Just for fun, I taped several strips of paper at the rear of my cowl hood. When at a stop, they pretty much just sat there. Once I got rolling...15-20 mph, they got sucked up tight to the holes in the cowl.Bet the ole butt dyno went off the scale. It probably doesn't hurt that this time of year the air is cooler.
Aren't you worried come July that the air going in there isn't going to be going thru the rad? Any not going in the air box might help lower the under hood temp so maybe a benefit in warm weather?
I'm trying to figure out a way to let some extra in on both side of my LQ9 to reduce under hood temps in summer. w/o taking it from the rad which will need it. Maybe a couple old ram air type inlets under the valance and some dryer hose?
The shiny aluminum, not the plastic. Don't want to take it from the valance with extra holes thinking that might decrease what does go thru it to the rad. I suppose as long as those were sealed it wouldn't effect what normally flows thru for engine cooling.
Do you think a cowl hood would let engine let escape. If they weren't so dated. maybe in 1990?
