For those that drag race their S10, at what speed would a person be wise to install a rear wing (like the S&W fabricated sheet metal type)? Thanks!
Can I dial in what year I want to go back to? (... assuming you're making a funny about "Back to the Future?")88 mph
Now that's funny! Full tube chassis, big cubes, and top fuel,... I'll need more than aero then! I'll be needing two parachutes and a full team of workers! This is just a back-half, four-link, 525BBC at 14:1 steel-body setup with about 875hp. There's no power adder, so the rear should remain well planted the whole run. These trucks aren't exactly like driving Corvettes, so I was just thinking that a little bit of aero treatment might make a big difference. I just don't know at what speed it starts to make any difference. Perhaps, and I'm hoping, that I don't need to worry about it unless I'm running a mid-8 second (1/4-mile) pass....Now when you go full tube chassis with fiberglass body running 500 inches on top fuel, yeah a wing will help.
I have the normal rake stance with a low front valance with a small opening, but the real benifit comes from the spliter on the bottom of it. That goes a long way to helping limit the dirty air going under the truck as well as putting good down force on it at speed. The air flowing over the back of the bed creates enough downforce that works good enough for me.Thanks, SilverWings! The only thing I dislike about front aero treatment is getting it on and off the trailer without damage.
as drgrcr said the wing won't do very much,but coefficient of drag will slow you down.if you use a bed cover the air will roll off tail and curl under back of truck,especially if the back is straight down from cover as appposed to a curved slope like an suv hatch/window back.that transitions the drag alot better.so no wing but a small spoiler @12degrees above plane at rear with a smooth transition from cover to spoiler. this will kick out that rolling air further away from tail and have less drag.the other thing you should know is that as speed increases the air from both sides at rear forms a tornado like turbulance seperatly and twist inward from each side.this is also motion to suck the cover air downward.also consider inner fenders or tubs in front as this helps for less drag under the hood.you may be able to gain 3/10ths on et. hope this helps.For those that drag race their S10, at what speed would a person be wise to install a rear wing (like the S&W fabricated sheet metal type)?
