Poweraxel, can we make this a sticky thread to compliment the "post your single turbo setup" one? That one says what everyone has as a whole, I want to focus on the turbo and how it functions. Find the best applications for what someone wants.

I want to get some real numbers here, both what you have and what you have tried. Let's all learn from other's paychecks...

Turbo make~
Turbo model~
Exhaust housing A/R~
Wheel trim~
Center section~
Compressor housing A/R~
Compressor wheel inducer/ major~
Which motor it is on~
Level of porting~
Exhaust diameter~
Cats?~
Your level of boost in PSI~
Full boost threshhold, in RPM, per gear~
Boost ceiling, in rpm~
Known RWHP?~
Peaky or broad powerband?~
If you could change it, how?~
General thoughts~

 

Turbo make~ Garrett
Turbo model~ T-66
Exhaust housing A/R~ 1.15 divided tangental
Wheel trim~ P
Center section~ Standard, dry, 360 thrust unknown
Compressor housing A/R~ .55
Compressor wheel inducer/ major~ 2.584, 3.584
Which motor it is on~ 13BT, 90 J-spec
Level of porting~ Street port
Exhaust diameter~ 3"
Cats?~ no
Your level of boost in PSI~ 15
Full boost threshhold, in RPM, per gear~
>1'st, it won't make 15. 2'nd, about 6000. 3'rd, about 5500. 4'th, around 4700. 5'th, before 4000.
Boost ceiling, in rpm~ keeps pulling to my 8000 rpm redline.
Known RWHP~ not known, but I was told 365 @ 12.5 PSI
Peaky or broad powerband~ Very peaky
If you could change it, how?~ I want to trade it for a 60-1, possibly 1.0 a/r, not sure .60 or .70 comp housing.
General thoughts~ This is a big HP/ big boost race turbo. I feel it is a waste for someone boosting under 20 PSI. It is too laggy
>for road racing IMO.

I have pics in the gallery~
