My dart is VERY stable at 150+, probably due to the high/long trunk lid, combined with the high quarter panels. 7731260-Dartpics+others125.jpg (181 downloads) 8..603 156 mph best, 2905 lbs 549, indy 572-13, alky

Still thinking about having my friend cut me a 6"x6ft. piece of 1/16th alum. today so I can tie it to the ft. valance and see what happens.......... 72 Dart 470 n/a BB stroker street car `THUMPER`...Check me out on FB Dominic Thumper for videos and lots of carb pics......760-900-3895.....

We also made removable plates to close off the upper grille that stay off during street driving and a chin spoiler. We eliminated the drip rails, side lights and door handles, while adding a pro stock style wing. The tin work closed off the rear underside behind the tires. Also flush mounted Lexan with no window trim and a narrow aero style scoop in lieu of the 6PAK scoop I originally had. How much difference any of it makes, who knows......but the car is very solid at 8600 in high gear. 8017458-205262_10150864472191044_117902798_n[1].jpg (189 downloads)

LOL On my little beasty - the front and rear spoilers have really settled the truck handling down at speed, but still unsure whether it's help or hurt the ET and MPH. A block-off plate in the grill helps by about 2 mph and about 1.5 tenths. I guess it's really tough pushing a barn door at 130 mph. At speed the back lexan window is sucked backwards toward the tailgate. I still need to try and solve that if I could. I forgot all about pursuing that part of the aero equation.

The other guy waited patiently for us to get started. Once the track official gave him the go & we finally got it started we did not have enough time to get the removeable deck lid & wing installed & made a pass anyway without them. We won the race & went 2 MPH faster than it ever has. Made me a believer that all of these big wings on the back make no difference. The car is not at speed long enough to notice. Rear wings are for downforce, NOT speed. Common sense tells you anything back there catching air will slow you down. I can add 1/2" to the wickerbill on the pro-Mod and slow it down 2 mph, but on a loose track we HAVE to have it up top to keep it stuck. Monte

I read every friggin' word of it� and it lead me to the conclusion that I've slowed mine down by overdoing the rear spoiler. I was having handling issues thru the traps - and the front and rear spoilers helped - but I think I overdid it on the size of the rear spoiler. I'm going to make back-to-back passes next time at the track, with and without the rear spoiler to see what it's been costing me. I am down 5 mph thru the traps from where it used to run at 18 psi of boost - but I figured it was all my loose convertor. Now I'm not so convinced.

You're only SLIGHTLY more aero than he is. I think I have you all beat.... There couldn't possibly be a less aerodynamic shape than the 66/7 B's. (???).
