Those light weight rotors are garbage.

The SVT guys are having issues with them chewing up blower housings due to defection.

Let me know when you want to sell the TVS with the 3.0 pulley.

2.5 is about as small as you can go on an M62 if I'm not mistaken, they become inefficient below that. Someone correct me if I'm wrong

2.5 is pretty far out the efficient range but there is small gains to be made if u have the cooling and octane to make use of it, id personally wouldnt go lower then a 2.7 but the guys pushing the m62 to the max for 300+ whp use 2.5 and 2.6 and **** tons of other mods. You can find it in the dyno section they are listed as number 1 n 2 for the LSJ with M62 309 whp and 303 whp.

Seems high to me, when I dyno tuned mine, the tuner did 24 back to back pulls with ambient temp at 70* (had some damn MAF problems) iat2s never peaked over 110*
