what is the benifit of this tiurbo over the sc61 besides more power. better yet would you put this turbo on a 2.2L engine? if i give you guys part numbers would it make a difference, because there is one that om looking at and would like some input before hand.

t3 or t4 turbine housing?

11seclude

ok I will tell you everything i see on the turbo.
on the compressor side it says A/R .70 then EC-1 then M24 and very very small it says 6376S
on the turbine side it says.
A/R .63 then it as the presicion logo then down by where the 4 bolts goes to bolt the turbo to the manifold it says THF3-76
oh and yes it's a T3
and it also looks like it is ported also it has thoes lines like when you just turned a rotor or something.

It's Big power, with a loss of initial response. There's no other advantage or disadvantage to it..

The SC63 is actually more expensive than the SC61, but not a lot more powerful. We rate the SC63 at 700-hp, which is only twenty more than the biggest SC61. By the time you add an S style compressor cover (4" inlet / 2.5" outlet), you already picked up 10 to 15 hp, which would put you just about there. The SC61 has a much more efficient compressor wheel. The big advantage with the SC63 is that this is not a small shaft tubo like the other T3/T4's are. Hope this helps.

Rod, is there an advantage to the 3 inch turbine outlet over the 2.75 inch turbine outlet? I have the .81 A/R hotside with the 2.75"v-band outlet but all other turbos I see have the 3" v-band.

Rod Short

Since you mentioned an 0.81 A/R. I assume that we're talking about T4 tangental exhaust housings. If so, then yes, you would see a benefit in terms of reduced backpressure. Exactly how much, I honestly don't have a figure for that. All of the T4's we sell have the V-band outlet with either a 3" or 3-5/8" diameter V-band outlet. Hope that helps and thanks for your business.

I don't understand the shaft thing. what will a bigger shaft do -VS- a regular shaft? Is it more stronger, is it heavy? I don't understand what do a shaft do?



don't the 63 flow more air than the 61 and wont that mean lower psi for big gains?
why does the 61 have a much more eficient compressor wheel than a 63? why is a 63 so much money then? is it just a bored out 61?


when do you think this turbo will start to spool on a 2.2L?
at what RPM do you think on a decent setup will this turbo see full boost lets say 15psi?

please don't get mad and flame me for what am asking I just want to learn.

Thanks.

OH sorry just sounded like him.


The big shaft from what I have been told is that it can sustain higher boost and thus higher shaft speeds. BIG Turbos use Big Shafts. Also since they have more mass they do lag more than a comparable small shaft turbo BUT I do not believe it is EXCESSIVE. Strength I believe what it boils down to.

damn Mr Short seems to know his turbo's
if you already have the sc63 keep it...i don't know anyone that runs it but it cant be bad! i have an sc61 and spools extremely well.

would i fall out of boost everytime i shift with this turbo on a 2.2L?
if you had to choose between a 61 or a 63 what would you go with and why?
at what hp/psi would this turbo be in it' s sweet spot?

Yes I am talking about the T4 tangential housing. I am wondering why the exhaust outlet is 2.75 and you only mentioned 3 and 3 5/8's? Are you talking about inside or outside diameter?

Sorry for the thread jack BTW...free bump for you

I was on a garret Equilevent to this turbo.
Made 367whp on fairly low boost on a stock h22. Full boost around 5k or so...
I loved the turbo, made my car drive like a supra.
spin through 1-2 gear, bog going into 3rd, spool all over agian only to start spinning agian.....bah

Im getting ready to use a Presision 6169E for my SOHC drag car, along with 2 stages of nitrous

ok what is low boost to you? why did you fall out of boost going into 3rd, you shifting to soon or what? how was boost comming in was it hard or a slow buildup?
my goal is to hit 580whp and I want to have at least 400+foot pounds of torque.
what turbo did you have by the way? what was the specs?
I know that **** had to be bad *** just the word supra puts a smile on my face

That was on 10lbs.
It would fall out of boost because in the lower gears it would spin the tires with ease.
When I got to 3rd after not having much load on the car in 1-2gear from the tire spin, The turbo would need to spool agian....
car wouldnt start moving until about 60 mph.
40 punch would just spin, only to bog when going into 3rd...
h22 has a failry short rev range, and the turbo has some lag.

The turbo i had was a Majestic hybrid bastard.
they Named the wheel a super 80 wheel. its a 63mm compressor wheel.
It was still a small shaft turbo, stage 3 exhuast
t3/t4 with E cover
.60 a/r on the cold side, .63 on the hot side

Rod Short

Sorry for the delay in responding . . . I've been offline.

The large shaft PT63 is a high pressure ratio turbo, meaning you can safely run up the boost. The large shaft design is more heavy duty. Turbos like the larger 67 are done on a small shaft.

It's an older design . . . been out about 10 years and has been used on the BUick GN primarily. I tend to like the SC61 better because it has a later design Garrett GT compressor wheel, which has a 79% efficiency rating at 17.6 lbs of boost and 72% at 23.5 lbs. This has been a much better seller. Hope this helps some . . . and thanks for your business.

ok I bought the turbo. (the shop where i was telling you guys about what i saw on the turbo) but what i dont understand is the part number says 6376S on the little yellow paper thats inside the shrud is this the cold side, 63? why does it say .70 on the cold side cover then? and what about the hot side is it a 76? why does it say 63 on the hot side cover and 76 down by where the bolts go to bolt the turbo to manifold? am lost.


--------------------------
ok I just tought about something
does 63 mean the trim of the compressor wheel and .70 on the cover means that is the ar of the cover so how would i know how much cfm's this thing flows. and the turbine side, is 76 the wheel trim and 63 the ar of the cover?

Hey Rod, why does the bigger t67 use a small shaft but the smaller t63 uses a bigger heavy duty shaft?

</TD></TR></TABLE>

Rod Short

The 0.70 on the aluminum compressor cover refers to the A/R ratio. The 63 is the diameter of the compressor wheel. The 76 refers to the trim of the turbine wheel, which in this case is a T04S 76 trim, more commonly known as a "P-trim". Check our web site for more info on deciphering these numbers. Hope this helps.
