61's

[DCVING 6]

Whats out there as far as 61's?
I always thought a 3200 stall was perfect for them, but I have seen them compared to a PT-54, which takes a 3400 min?
Then there is a PT-61, etc.
Where are the different models most efficient at?

We only offer one PT61 and it requires a 3200 stall and makes 650 flywheel horsepower which is good enough for high 10's on a heads and cam or mid to low 11's with a bone stock motor

There used to be a TA61 or TE61 but that's a completely different turbo than our current PT61. The new 61 uses a new Garrett 61mm compressor wheel off the GT35R ball bearing turbo. It's a very efficient wheel and a very quick spooling turbo as well (perfect street/strip turbo)

IMO this is the largest turbo an untouched motor can handle because honestly I've maxed out the flow of my heads already at 25 psi of boost...I tried running 30 psi of boost and I only picked up .007 of a second (you would think 5 more lbs of boost would be ALOT faster than that!)

Yep, I ran fastest at 24-25#, and actually at 27# with a bit leaner mixture and still no KR I run a tad slower!

TA-61/ TE-61/ pt-54(i believe) Cpt-65.

Thats all I know. I love my 65 it's great....

Hey Don,

Whats the story on the GT6152S? recommended stall, min injector, etc.

3200 - 3400 stall works good, 50's is probably the minimun inj.
I did get away with 009's for a year.
