1969honda Posted June 24, 2017 Share Posted June 24, 2017 (edited) Looks like you could use a hook pile tape lowering line for that tether. Or find a Rigger and supply a case of beer... Edited June 24, 2017 by 1969honda Quote Link to comment Share on other sites More sharing options...

RebekahsZ Posted July 8, 2017 Author Share Posted July 8, 2017 Do any of you really understand how the flat spoilers work that the Mustang crowd uses? Just looks to me like the make the air think the car is longer... can't find any thoughtful discussions (on line) regarding how they supposedly work.

260DET Posted July 14, 2017 Share Posted July 14, 2017 My guess is that they are drag reducers when you straight liners have a air brake out back, maybe they incidentially help keep things tidy back there too. Quote Link to comment Share on other sites More sharing options...
calZ Posted July 14, 2017 Share Posted July 14, 2017 Are you talking about a flat plate angled upwards, or just a horizontal extending from the back of the car? Quote Link to comment Share on other sites More sharing options...

JMortensen Posted July 17, 2017 Share Posted July 17, 2017 I think the idea is that by making the car longer the air recirculating off of the top and bottom doesn't converge right at the back of the car. This lowers drag and lift. I tried to get McBeath to comment on this with regards to the whale tail on a Z, which also doesn't really have a huge angle to it, yet produces pretty significant downforce. He said at that time that he hadn't done too much testing on spoilers. I let my RCE subscription lapse, so I haven't kept up with his aerobytes articles as of late. Maybe he's dealt with whale tails. If so, I think that would be applicable or at least analogous to what is going on with these drag/LSR spoilers. My gut says if they didn't work they wouldn't be so ubiquitous.

I would have to agree with that. Drag Reduction. Pro stock cars are particularly susceptible to poor track prep and wind gusts. On a slippery track they are the first ones to complain as the cars skate all over the place on the top end. They have very little down force.
