Precision SC-61 Ball Bearing vs. Garrett GT-35R Ball Bearing

[v2ner]

what kind of bullshiet is this...show me some scientific proof on what you just said and i will send you my sc61 bb that i just purchased...

anyway...i went with a sc61 bb because i got it brand new for a very good deal...and i called precision up and they said at the most the gt35r will make 20-25 more power than a sc61 bb because the gt35r has a slightly more efficent wheel...but for the price difference and the 20 hp difference...i made the smart choice and got the sc61 bb for much cheaper...plus i did not have to wait for the sc61 bb...the car is up and running now...feels great...

Hey, I'm happy for you dude. I'm just putting my opinion and experience on this thread. Why don't you call up DEVO and ask for there opinion. You never know, maybe me and my buddies just had bad luck....keep in mind these were ran 27+ psi. Have you had a 35R?

I agree that's a naieve comment. Please show me some proof or don't make blantantly false comments about things.

see that you live in jersey...i live in philly...also see what you run a ssautochrome mani...how do you like it...is it the obx one...has it ever cracked yet...also how do you like the dejon tool intake mani...pm me your aim...thanks...

what is devo...

so you are saying that you have had a sc61 bb before...what happen to it...

do you have a gt35r now and you have had it long enough to say that it out last the gt35r...

Devo tuning aka DVDT Fab

AMS tested the 35r against the non bb sc61. 35r spooled 100rpm faster and made 10whp more on a 600whp setup. The bb sc61 is likely a bit better performer.

thank you this supports my opinion, i personally own a scm-61 and its a great turbo for the money. if you dont already have a aftermarket manifold use a mitsu manifold and get the non bb scm-61 and if you already have a t3 manifold get the sc-61 basically the same turbo just made for the different manifolds. like i said in my first post save the money and if you dont already have cams buy those or whatever else you may need.

DEVOtuning...not DVDT FAB. Same state and group of friends. Yes, I now have a 35R on one of my DSMs. Before was a SC-61. Like I said, we all had them runnin at 27+ psi with 9k redlines. I guess you can say it is a hit or miss...mostly miss with me and my guys with the SC. Most these cars have moved on to a MP 70 though. Don't get me wrong, that's a great turbo though.

i have a t3 mani...and my sc61 just ####ed up on me which is why i needed a new turbo...do not ask my how or why the sc61 ####ed up...it was fine with no play what so ever...then one day under normal driving conditions it just started pouring out smoke and oil...we got a new sc61 bb because we got it at an incredible deal plus it comes with a 1 year warranty...if you guys only knew how much i got it for...then you would have made the same decision also......

do not get me wrong...i abuse the shiet out of my car also...we just blew our t3 sc61...it just gave up out of no where under normal driving conditions...same as you guys when we do race it...9k redline...we try to get 25+ psi on pump gas also...

but back on topic...we are comparing the sc61 bb to a gt35r...not the regular sc61 non bb...

our motor is built to the max and we just want to start maxing out this turbo...

what is a mp70

thanks...

That's cool cause that's when it's alive. Sorry, I never do anything over 20 psi on pump gas...unless it's alky/meth injected. Not flamin you but 25 psi is not even close to the max. We run 110 octane. Master Power 70.

my car is driven on the street everyday it is running...it is not a track only car that gets 110 only...we squeeze 25 on the streets with pump gas...and i know it is not the max...but i am not going to run 110 all day long......remember we are talking about street here...my car is not a track only car...in fact i have never taken my car to the track yet......that master power thing...that is a ssautochrome turbo off ebay correct...how do they perform...i have heard people complain about seals blowing out and that they do not come balaced from the factory...pm me your aim so we can talk some more...thanks...

this is the master power turbo correct

how long do they last...and how much does it flow...i know a sc61 flows 65...what mani do you you guys hang it off...

 

[90blacktsiawd]

I have a friend running that mp-70 on his 383 iroc z. He likes it. Though his car still needs some odds and ends. If he floors it in third he breaks the back tires loose at only 6 psi when at 8 psi on his old s/c it didn't do that. I personally told him to go to a more reputable vendor but he didn't listen.

 

[v2ner]

That one looks different but it could be the same one. It flows 84 lbs. Custom ex. man. with an SP cover. This is on a white EVO II. This one on is not a DD anymore. I don't run it. I go to tracks once in a while but they kick you off if you don't have a cage under 10.9 (if i remember correctly). Sorry, don't have AIM and I'm just a newbie on this site trying to learn.

That's hilarious. This turbo would lose to a civic at the boost level. Are you kidding? It's only meant to be ran 30+ psi....are you sure it's the correct one?

you seem to know alot more than most people on here...when does turbo start to spool...when is full boost...what is an SP cover...you seem know test alot of stuff that people on here do not dare touch...also what internals are in that motor...thanks...

Granted that boost is probably way to low to be in a turbo of that sizes efficieny range. You have to remember he's got a 8 cylinders & 383 cu's (~6.2L). Its a whole different story vs a 2.0L.

But what amazes me is that someone is actually running an SSautocrap turbo for a high HP/boost application & its standing up? Or is SS just selling a knock off of another turbo, like they do with all their other products, & your buddies are running the "real" version.

 

[v2ner]

Honestly, I think that one's a knock off. The master power 70 we're runnin actually has master power on the compressor housing. We ordered it straight from Brazil. I don't buy the SS crap either. SP = anti-surge housing with bullet style holes. Check dejontool's website under turbos. 40psi @~5300RPMs. The motor is built but not stroked. When we ran 35Rs, everything was stock except valvetrain, HG, and head studs.

Speaking from experience from riding in the car i've never known a civic to go this fast. Not that they aren't out there but certianly not riding around on the street on a regular basis. I had the same conversation with him a hundred times. You'd be better off getting a turbo you would run in it's efficiency range. But being a v8 it does change the game alittle bit. Displacement plays a part in where the efficiency range of a turbo is. If you look into alot of the v8's running a turbo they tend to run lower boost levels. Most of the bolt on kits you'll find are for 6-10 psi or so on some huge turbos. Turbos that would be able to push 600+ on our cars.

It wasn't the exact turbo that was on that ebay page. It doesn't have the polished compressor cover. The cover says master power and ar/.70 on it.

 

[ICE_T]

currently, I'm running a scm-6131rle. it's a scm 61 bb, with stage 3 turbine wheel (76trim)

I hit 18-19psi, arround 4200-4500rpm, with cam and smim. My friend, with his br580, closly the same turbo, hit full boost arround 4000rpm.

So for the spool with thoose big turbo on pump gas, it's not bad.
