perkins turbo off a catapillar?
i have acquired a perkins turbo off a catipillar. i am trying to find the specs on it. its off a 6.6 liter 6 cylinder. the part number is 2674a256. i am trying to find the specs for it. i was thinking ab trying to use it. i think it has a t3 flange on it. how would i get the a/r for the turbo? can i measure anything on it?
|
measure the diameter (inducer and exducer, look those up if you don't know what they are) of both the compressor and turbine wheels
|
it has a 76mm compressor wheel.
|
66.5mm exhaust turbine
|
If you can get the engine serial number from the engine it came off of, I might be able to help. I work at a Peterbilt dealership but we are also a CAT dealer. That part number didn't go anywhere on my CAT dealer site. So I can look it up by ESN and then get all the specs of anything about that engine and it's components.
|
what is the inducer (smaller inner measurement) of each wheel? How many blades does the compressor wheel have, and what is the diameter of the intake?
|
it has 7 big fins and then small ones inbetween them. i just dont know where to measure the inducer at. and the diameter of the intake is 3 1/2 inches.
|
anymore ideas?
|
the inducer is 50.8mm and the exducer is 57.15mm

are you measureing the turbine side or the compressor side? tose measurements line up closely with some of the available hotside wheels. for instance the GT 2835 turbine wheel is close at 2.02" x 2.204" or 51.3 mm x 56mm :scratch: kenn |
no its the cold side
|
Way too small!
|
but the turbo is huge.its like twice the size of my stock turbo. so is the compressor wheel.
|
post a side-by-side pic of it and your stock turbo (I presume 2nd gen)

here they are side by side
|
i would hope that turbo would out perform the stock by a mile
|
you might suffer from some lag with that one...
|
that is a whopper
|
is that sarcasim spoolage? i got 2 of these turbos for 60 bucks. they are in perfect condition. i figured i would try to use it rather than going out and spending a hole ass load of money on a name brand turbo.
|
The one i got off of a tractor was too big :(...
mine is a T6 based turbo. http://i201.photobucket.com/albums/a...7/P1010052.jpg http://i201.photobucket.com/albums/a...7/P1010054.jpg |
this has a t3 exhause flange on it.
|
give it a shot man, that's all i can say. the compressor wheel seems a bit undersized compared to the compressor housing but it will flow more than stock.
|
just wish i knew the a/r on it.
|
i just found out it has a .70 a/r on it. is that good or bad? wont it spool faster the lower the a/r
