Twins on a D-max

[Bobo]

Looks like the BB that McRat is selling is listed from him at $4200.00

No way in hell I'd buy that when I can get twins for a couple hundred more!! The FI GT42 non BB spools great as a single on a bone stock LLY that I'm tuning(no twin CP3 pumps). I'd go that route to save some money. If I'm spending 4K or more, I'm getting twins! BB turbo's don't last longer. The center section can't take the heat like a thrust bearing charger due to the material lost when adding the BB....that is why they are water cooled and thrust bearing chargers typically are not. BB chargers normally cost about $1K more than the same charger that is not BB. You can darn near buy two FI GT42's for the price of one BB 42. Here are a few pics of a FI hybrid BB turbo. If it spools fine, we'll try the non BB and report back. The GT 42 is this turbo's baby sister, so the BB was suggested by FI just to be safe for spooling purposes! It's going on an LB7 as soon as the motor build is done!!

Thats pretty cool stuff being in the 120 club with your daily driver. I guess the GT42 is now the current cats meow. I like the your description above it would be nice to know where his boost and EGT's were during that pass. The BB having a longer life is not what I have noticed in the diesel world. It has been my understanding that BB in a diesel is very sensative to needing clean oil. The Phords BB turbo in the 6.0 sure has gone through an expensive learning curve. The only reason I was interested in a BB is hearing that a BB will spool anywhere from .2 to .5 seconds quicker. But anyone who understands how twins work would know that isn't an issue on the bottom charger. It also makes me wonder if choosing a BB if it would magnify turbo barking when being used as a single.

My wife (Kat) ran 120.4 mph at LACR last weekend with the PPE GT42R. It made 53PSI boost through the lights at 3500rpm, running 1650 EGT's peak. The DA was 3680 feet.

We dyno'd it today at 755rwhp (737 uncorrected) with a brief 4 second pull on Westech's SuperFlow making 52 PSI and under 1600 EGT's.

So far we have had no issues on the GT40R ball-bearing trucks, nor the 42's. These are also available in plain bearing versions at much lower price.

Twins are a great idea and have done well on the Dmaxes, I certainly have heard nothing negative about them. They are the only real option if you want more than 60PSI with anything that resembles efficiency.

I have PPE GT42 journal bearing charger kits in stock that are very competitively priced, and will support past 750rwhp. Yes, the ball-bearing water-cooled option is more, so we offer both.

Ball-bearing chargers are water-cooled because you cannot run high pressure oil through them, so you need the water for cooling. Water is far better at cooling the center section, and reduces oil temps.

Good luck on the build up, let us know how it works.

Geez that turbo is from Forcedinductions??? Which one is that?? That compressor cover looks quite a bit bigger then the GT42 cover. What is that turbo rated for in power?? I know they have a street racer D-max customer in Iowa or Idaho??, that is running one of their big hybrids as a single that is putting down 900+rwhp on #2 only. Heard he is taking some folks money in the street race scene.....lol :hehe: . Would love to see a new C6 Z06 line up beside him.

 

[moss]

isnt a bb turbo much more expensive to rebuild(if rebuildable) than a thrust bearing turbo?

 

[Slick]

Some probably are, but I think I heard that none of the GT4x series of chargers are rebuildable.

The GT series DBB's are not rebuildable, but I know the guys at FI rebuild all of the GT non-bb series.

Man that compressor cover looks just like a 42r, the larger frame Garrett turbos don't appear to have a v-band flange on the outlet.

A couple of my buddies run 4780's on their supras and they don't have Vband flanged outlets either, so I would bet it's a 42R of some sort.

Is it a 4202 wheel? Or a 4276? The cover doesn't appear to be a 45 or a 47? Maybe a larger wheel stuffed in a 42r cover??? :S

Put a dollar bill on the 42R and take a pic. I don't think it will look like the one I posted after you try that!:rockwoot:

I don't have a 42r handy right now, but here's a shot I took a few months back with a pop can and a 42R. A dollar bill is about 1/8th inch short from reaching both sides of a pop can, and about 1/4 inch longer than a popcan is tall.

I'm 99.99% positive that the compressor cover on that turbo is a 42R cover. I'm not saying it's a 42R wheel, but it sure looks to me like it's a 42r cover :ft:

<edit> Whatever it is, It sure will be fun to see how it runs on a built LB7!! Good luck!!

That cover looks to be a 6" inlet and ALOT larger then a 42 housing. I would imagine its a hybrid of some sort. Also what gives it away is the backing plate......looks like AL. All 42's are cast that I know of. With FI you just never know. I will call them to see. I am curious now....lol

Yeah, that backing plate isn't a typical 4294R backing plate........... It just looks nothing like a 45 series cover. :huh::

Ok I called and they sent me a picture link of it. They didn't tell me which turbo it comes off of, but its definitely a hybrid and its a Dual BB setup.

42 is on the left...... :woohoo:

 

[tarmacblack]

HOLY ****!! Yeah, I was way wrong. Me = wned: :bow:

So did they tell you what the inducer/exducer was on that bad boy?

What are you using for the primary on that setup? I'm very anxious to see how it turns out. :woohoo:

Jose one of the owners said it was a hybrid 82mm :rockwoot:

:st: :woohoo:
I want one!!!

:st: :woohoo:

Same here.......guess I need to go have a kidney removed....lol

 

[Bobo]

I told ya it wasn't a 42! This one is going on a pulling truck I'm tuning...as a single!!

 

[05lly2500hd]

Good God!!!!!!!!! That thing is ******* BIG!
