Well, I bought the II Silver 62 but i ordered it with a 12 cm exhaust housing....I made 530hp/1050tq. with It and my Crazy Larry and MP8..(See my Sig.)
There's another guy on this forum (OkeeGoat06), He has the exact same setup as me except he has a HT62/14.....I'm not sure if he has a TC Lock up switch yet.....Anyway, He ran a 12.9 @103 with his......
I haven't made it to the track yet but will in the Spring....If he's running high 12's with his setup, I should be there as well, especially if i'm locking right after it hits 2nd....
With your setup, If you drive it daily, I think the Silver 62 would be great......BUT, If I had it to do over, I might have gone with a 64/71/13 setup........
You'll get there pretty quick with just a couple more mods.....BTW, I like my MP8 you might like it as well. look into it..........Oh Yeah, my numbers and his times are with STOCK STICKS AND STOCK CP3.......
