Turbo-What Do I Have?

**billet racing** · 01-22-2012, 01:42 PM

Here's what I have.

Turbonetics T-6 Flange, Exhaust A/R 1.30 Markings TRI 1860

Cold air Intake 2.35"
Impeller Marking Cast I, A Ink Stamped RO553
Inducer 2.325" Exducer 3"

Exhuast
Impellor Marking Cast 341 T,O
Exducer 2.69" Exducer 2.75"

On the exhaust manifold, the wastegate is 2.63"

So what do I have? What kind of power will it support? Putting this on a 496" tall deck Bow tie block. Merlin 320 aluminum heads. Crower crank, Oliver rods, JE pistons.... Good stuff here. Wanting to go with the Fast EFI system. On fuel. 1110-116 Octane fuel not an issue.

Pictures below.

I am no help with the hair dryer id...sorry. I am curious...what/whos headers are those??

Those should work good. That's about like a t76 turbo. It's kind of an odd turbo though, because of the T6 large AR exhaust housings. With the small turbine and compressor wheels normally a t4 housing would be on a turbo like that. But in a bbc jet boat, it should work just fine. I'd guess it'll probably be good for about 1200 HP or so, maybe a little more. Where did you get them? It seems like a custom set, but maybe it was a diesel turbo?

Picked up from a guy in Lake Havasu. He rebuilds turbo's and had this setup on his boat. I was in Havasu at the time and toasted my current set up, Ray Jay 300 series. Said they were not worth rebuilding. Purchased this set up from him. The turbo's are fresh, and everthing is jet coated. Custom made headers. 3/16" tubing. Didn't think to get all the details at the time. Just explained my intentions, and he said they would work. The price was real good.

I would say that you definitely have more turbo there than your Ray Jay setup. Looks like some work went into the headers. Did this guy guy primarily rebuild turbos for diesels? If so, AP67 may have nailed it on the head.

Biggest thing you need to do is reevaluate the fuel system...these turbos will work much better than the RJ's. You will have more power on tap for sure. You need to make sure you get enough fuel in that thing.

Jerry, just what are your intentions? I know you're not afraid to have a race gas only mill... I feel a MONSTER is in the works

Actually those have 59mm inducers, WAY smaller than a 76mm.

Let me know before you buy the F.A.S.T. I get a better deal than most.

**billet racing** · 01-23-2012, 04:44 PM

The Ray Jays got me started on the turbo path. I'm hooked now. This is the next step, and want the ability to increase turbo sizes. Not afraid of going to alcohol or e85 next either. this is just a stepped program, and I'm learning alot as I go.
The 21' Daytona is a great test vehicle to work with. It can handle anything you throw at it.

I should have clarified, and not put t76, because there are many t76 turbos out there and some are given the designation by the inducer and some by the exducer. I said they would be worth about 1200 hp and they are. I said they are not normally a T6 large AR which is also true, because I was referring to the gt3076 like garret makes as a comparison. the map is below is the gt3076r and the compressor wheels are very similar, both in trim and exducer diameter. This is exactly the reason why its best to know both inducer and exducer size, and which one of those a turbo company references to designate the size of the turbo.

1200hp? Not on a 496, no way. Will it make more than a Rajay? Definitely a little, due to the bigger hotside, but these turbos will be WAY off the map on a 496. I'd say no more than 900-1000 hp, which could be made on motor alone if built right.

Turbos don't care what engine they are on. It is about airflow and nothing else. Are they the perfect choice for this engine...no, but they will work just fine. This engine will be most efficient through mid range and around 12-16psi of boost. But these can be turned up, and if a high octane fuel is being used, like he stated it is, then these will do 20+ psi, but just aren't as efficient at that level. You need about 55lbs/min of airflow per turbo to flow the air for 1200hp. These turbos can flow that, the large engine also helps with hitting that number compared to if your tried to make 1200 with these on an LS or something with less cubes, which would require a little more boost to accomplish. 1200 is doable with this setup....it's just math.
