TE45a (.82 Garrett) efficiency level???

[turbov6joe]

Those using this turbo with the .82 Garrett exhaust housing, what boost level have you found this turbo to make the most efficient power?

I went 127 at 25 psi 130 mph at 27. In my opinion about 26-28 psi is the spot for the 45.

I have heard of some going to 35 PSI with this turbo but only with stock heads. Seems that cars with ported heads have lower PSI sweet spots, less than 30 PSI, probably due to the ability to get more in the cylinder and use up more of the turbo. I'm trying 30 PSI before the year is out. My dyno runs were with around 29 PSI.... I have a PTE .63 exhaust housing.

Joe you know that I was liking 23-24 lbs but I think I might have to turn the wick up.
