Aero, and lift was actually something I was thinking about the other day, although for different reasons. I was thinking about some tasteful (this part is key) mods to help with engine bay airflow since the 2.8 runs so hot.
I was thinking about hood mods, and possibly tweaking the fog light surrounds, but it got me thinking about the impact of additional under car airflow, and reduced stability. Granted... probably not much impact below 100, but every now, and then when the opportunity to track my car arises, I don't want to find out my "improvements" weren't. :cheesy:
exactly. A 2 inch lip on the edge of the rear trunk lid will help , actually a 6 inch blade is ideal for max downforce but a two inch lip is good enough, you can adapt an ebay stick on lip easily enough; just separate the air. The votex generators are a waste of time imho. The fact is downforce can be improved at the front by venting the hood, a couple of 5 x 10 inch holes each side of the hood along the fender line and inwards, starting about 6 inches forward of the rear hood edge. But cutting the hood of a saab is probably not worth the effort, there are structural braces get in the way....I wouldn't have thought downforce in the front would be a big issue. At speed, usually it's the back end that tends to lift on most cars.
Pretty much this... There is no low pressure zone over the hoods of our car so hood scoops would serve almost no purpose while vents would only help for heat soak.I'm with you on only requiring the cooling once you stop moving, but slow moving traffic isn't great either. I have a D088 radiator, and after installing that monstrosity I don't think you could ever overheat this car, BUT all the plastic under the hood, and the batter say otherwise.
That would be the main driver for some sort of hood based allowance for cooling, heat does rise after all. Some understated hood louvers could be appreciated I think.
This is false. Really, how the heck do you think the intake plenum for the HVAC at the base of the windshield works??? Or a '60's tri power ram air hood?Pretty much this... There is no low pressure zone over the hoods of our car
