Are you looking for a good seat of the pants increase? Going from a 60 to a 62 isn't a big jump in CFM. Now if you go to a TE-45 or 70 then you will see a nice gain.
I believe you're correct about not much improvement going to a TE-62 but regardless those 009's ain't gonna cut it...especially
with a TE-45...for the 62 you would need at least 50's...55's for a TE-45...
hey just. I think you have more to go in the combo you have change inj. and tweak a little more thiers a mid 11 in your combo right now, but that just my opinion.
I just got a TA-62 from John Craig. It's awesome. I had a TA-52 before which is similar to the TA-60. I could feel my car pull harder with the 62 than I did with the 52. It spools great. I do have a Precision (3200) 9.5 non-lock though. I love this turbo
