If thats the case and your driving an Evo 8/9 then you should check out the link from UNDUMMY up above.
If you are talking 600whp+ Drag car, or track dedicated car ONLY then I can see running a 20/50. That dense oil is not needed for a DD car with stock internals (bottom end) IMO, especially if your running a high HTHS oil like Redline. Their 30w is better than most 40w's on the market (correct me if im wrong please) needing a thicker HTHS than 3.8 with stock internals makes no sense to me, especially since OEM recommends M1 10/30 which has a HTHS of 3.2. I AutoX on ocasion, and if I ever get my Evo up at Willow Springs, or Chuckawalla Raceway, I will run RL 10/40. Since the car goes to work and back and I drive within the legal limits (kinda of hehe) I really think the 5/30 RL should be all I need.
Any Other Opinions? They are much appreciated.

Your and evo guy and dont know who Curt Brown is? I have read a bunch of your post and I think your stressing a little much on this. Everyone will have an opinion and who's is right is anyones guess. What I take away from all these responses is good luck finding two people to agree and I see a bunch of EVO's running around so mabye there is no right or wrong answer. My old ride made over twice factory power and went 100000 mile on factory fill 5-30, the tranny, and pistons went well before anything oil related. Good luck
