Big turbine Borgs
 
Well iv been through several turbos now on my 6.0 and they have all been 76mm compressor and that's not whats been bothering me.. the on3 76-65 sucks above 7 psi. Magnum 76-68 was good till 10 psi but sucks over 5k imo and then I moved to a pt 76-75 cea. This was a big upgrade. Pulls all the way to 6k and gained me a lot of power... But since I'm 2wd and in an extended cab its hard to control that power down low and make it usable especially on the street. Traction just doesnt exist with my setup... So I'm looking at a different turbos again so I can control the power down low a lil better and for it to come on a little slower and smoother but for it to pull crazy hard up top getting me some good mph up top... Borgs have been on my radar for a while now because I like the turbine options they have and the one foose just got with the billet 11 blade compressor looks sweet and did a little reading and they seem to be great so what do yall think?
I'm think s475 et-r Ho with the 92mm 1.15 t4. I think this would leave me with a good pressure ratio. Prolly 1-1.5:1 I would guess. Do yall think its gonna be overly laggy or any bad side affects from that big turbine? Would be nice for some feedback from someone that's used that turbine in a t4 but I haven't found anything searching. I think it would be beastly...

lglowe 09-29-2012 06:10 PM

Oh yea.. I have nitrous for track days if I need a little spool assist...;)

smokeshow 09-29-2012 06:50 PM

Why not keep that turbo you have now and get a boost by speed controller? Then you're not lacking low end when you want more of it.

ZO6Ted 09-29-2012 09:22 PM

Hmmm,what is a boost by speed controller?

Quicklynx 09-29-2012 09:31 PM

Foose is putting that on his 4.8.

On a 6.0 that thing will be a beast. I can't expect any noticeable lag.

TrickTurbo 09-29-2012 09:45 PM

Right foot is a good controller. ;)
to make lazier for more down low controll.
It's a trade off up top Or down low. Gain down low either nitrous or One of those swing valve.???( wrong term can't remember correct one)

Close... but foose is gettin the one with the 83mm turbine. That on his 4.8 and the 92mm on my 6.0 would prolly act very similar I would think...

Quick spool valves! But I'm pretty sure I like the constant top end pull then the low end instant tire burning power... Atleast on the street...

Internet Home of the AMS-1000 & AMS-500 Boost Controllers

smokeshow 09-29-2012 10:13 PM

Boost by speed controllers are programmable boost controllers. They allow boost to increase as you go faster so it doesnt overcome the tires.

Man I need to hop on the Borg Warner train. This baby 65mm exducer is killing me

That's what I get for skimming. :)

I don't think you'll notice the lag at all on the 6.0. I don't even think Foose is going to feel any lag really on the 4.8 with his setup, although nitrous is really going to push that sucker faster.

I talk to OGs that were building turbo cars in the 70's and 80's and talking about 1-2 seconds of turbo lag. I can't even imagine 2 seconds of lag.

Could you do twin ON3's and make up for the smaller exducer?

I'm probably going to do twin ON3's. I think I'll get what I want out of that build, no problem.

is this the one you are currently using? On 3 Performance 76mm Turbo Camaro LS1 LS2 LS3 LS6 LSX Camaro Trans Am 6.0l 5.3l | eBay

If so what kind of power are you making?

o2camaross 09-30-2012 01:45 AM

I'm running the 76 with the 1.0 ar divided housing. Never been on a dyno but on 14psi in shitty air it trapped 121. I'm hoping for mid 120s next time out. Its a good turbo for the money but I wish I would've gone with a s475 in the first place. I wouldn't mind doing twin on3s but I don't feel like redoing the piping. My roommate is running twin on3s on his ls1 Camaro but we haven't tracked it yet.

lglowe 09-30-2012 01:35 PM

You would Prolly have been better off with the standard .96 open housing. I think that 1.0 divided is actually smaller...

But I'm not looking to getting a fancy boost controller. I like the borgs and options you have with them. I want something that gonna maximize my HP per # of boost and i know its not gonna be as snappy around town and what not. Just wanna know what yall think about my choice in turbos/turbines...

o2camaross 09-30-2012 02:01 PM

I think the 92mm turbine would shine with your setup. Im guessing you want to stay T4 huh?

lglowe 09-30-2012 02:16 PM

Yea. Don't wanna to change to t6 pipes

o2camaross 09-30-2012 02:56 PM

yea me neither. Im going to get a s475 with the 87 wheel and 1.10 housing for my 5.3. I think the same with a 92 and 1.10-1.32 or what ever it is would work very well on your 6.0

lglowe 10-01-2012 09:33 AM

Just talked to forced inductions. He said a s475 with billet 6 blade wheel and 92mm 1.10 should work awesome for me... He siad the 6 blade will move more air on the 10-14 psi range over the 11 blade wheel so that'll work great for my setup cuz that's the boost range I stay in and the turbine isn't as big as I thought. It's 92/83 so it won't be all that laggy according to him but should pull amazing up top and back pressure should be just about right

o2camaross 10-01-2012 01:03 PM

very nice!! Im about to buy a T6 s475 with a 96mm wheel and 1.32 ar from a local guy. Im sure its a little overkill for my 5.3 but it should pull like a freight train up top and when I build a motor itll be just right

Ferocity02 10-01-2012 01:40 PM

Where are you guys buying the BW turbo's? I've had a hard time finding them.

Atomic 10-01-2012 01:50 PM

Im about to see what the little 87mm turbine on a t6 does on a 402 0_o

nonnieselman 10-01-2012 01:50 PM

lglowe 10-01-2012 01:58 PM

Oh coarse my plans aren't finalized yet but I also talked to reed at works turbos at lunch time and he's sayin go with his s476 eet with race cover and the 87/81 turbine 1.25 ar for what I'm lookin for. The 92mm is old tech and the new 87 should be what I'm hunting... Hummm

Jake99 10-01-2012 02:11 PM

You could always do a s480 if your looking for a softer spool. All these threads of people gaining power with these big bw turbos has me pretty excited, my 62mm wheel is pretty much tapped out at 16 psi already

Reed knows his stuff...that turbo will be awesome for you. I ran it for a while and its pretty awesome, just too small for my 402 for my goals. But spool was great, and power was great.

o2camaross 10-01-2012 02:16 PM

How do yall think a T6 s475 with a 96mm wheel and 1.32 housing will spool on my 5.3?

Atomic 10-01-2012 02:22 PM

Longer than I would like, but top end should be great...eventually :lol:

smokeshow 10-01-2012 02:25 PM

It would take a very long time...lol

o2camaross 10-01-2012 02:26 PM

haha yea its going to feel like eternity compared to my 65mm turbine. But its a pretty good price and I can use it when I build a motor.

o2camaross 10-01-2012 02:26 PM

well should I not get it?

smokeshow 10-01-2012 02:29 PM

You might regret that you did. Lag sucks.

1slow01Z71 10-01-2012 02:34 PM

What you're asking is about like asking for cam specs. They're all going to be a little different, I think everyone has been pretty happy with turbos from either of them.

Jake99 10-01-2012 02:36 PM

I have a friend with z28 that's got a 408 and he's running twin master power 70s with a .68ar, it spools good and pulls clear to 7k no problem, twins are over looked to often, they will give you the best spool vs top end power. Cars gone 1.27 60foot

lglowe 10-01-2012 02:45 PM

Did you have the race cover or just the regular slip fit cover on yours? He said the race cover is good for another 75 HP..

lglowe 10-01-2012 02:49 PM

I wanna say I was reading over on tech before and some of those car guys had that same turbo on 4.8 and 5.3s. Starts getting good boost around 5000 rpms in first but after that they are bottle rockets ha ha ha

o2camaross 10-01-2012 02:55 PM

yea im thinking it may be a little slow in first but once its spooled 2nd and 3rd should be ridiculous. My 2.50 first gear and 3.42s may help it though. Im just gonna get it I guess and build a new hot side for it and if its to laggy Ill put it on the shelf till I build a motor and slap my T4 setup back on it

nonnieselman 10-01-2012 03:13 PM

50 or 75 shot till it gets in boost will make it much funner..:devil:
