Drax240z Posted September 25, 2000 Share Posted September 25, 2000 Well the title presents my dilemma rather well. The car currently has a whale tail on it. I like what the tail does at speed, but I also really like the idea of a bit of a sleeper. I have a BRE style rear spoiler, but I really don't think it does much over 75mph, certainly not like the whale tail. I shouldn't be driving faster than that, but I do sometimes. Any thoughts or comments about the aerodynamic differences, specifically from those of you running whales tails? ------------------ "THE STREETS WILL FLOW WITH THE OIL OF THE NON-BELIEVERS" Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html Quote Link to comment Share on other sites More sharing options...
Mikelly Posted September 26, 2000 Share Posted September 26, 2000 My particular unit supposedly generates 1000# of downforce at 120mph... That was what sold me on it, but I couldn't tell you if it does... I have had the car to around 140mph several times and the seem that rests against the hatch cracked paint due to the downforce on the 1st high speed run.

Drax240z Posted September 26, 2000 Author Share Posted September 26, 2000 I noticed with mine that I had a bit of a squeak/rattle coming out of the hatch. (from it bouncing up and down) At anywhere over the 80mph mark it totally stopped as I assume the hatch had enough downforce on it to keep it down... Tough decision, but I'll probably go with the BRE style just because I think it looks better. Or better yet, maybe I'll try comparing the 2 on the same car before I paint. ------------------ "THE STREETS WILL FLOW WITH THE OIL OF THE NON-BELIEVERS" Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html Quote Link to comment Share on other sites More sharing options...
Andrew Bayley Posted September 27, 2000 Share Posted September 27, 2000 As a side effect, have either of you guys noticed a decrease in the amount of exhaust fumes pulled back in through the hatch? I'm having a lot of problems with exhaust gases seeping back into the cabin. Most of it is due to worn out weather stripping, but I wondering if a small spoiler would help the aerodynamic flow over the hatch any. -Andy Quote Link to comment Share on other sites More sharing options...
