Some changes since I last posted. Went with Precision 74mm Turbos to replace the Gt4094's as they were too small, and went to a gen 3 intake manifold. Making some progress!!

Dave, looks great!

Sorry I was not able to get a price to seel you those turbos fast enough.

Please call me as I lost your#

I have a couple of ideas for the pressure line on the power steering pump if necessary!

Dave,

Nice work and great looking design

I'm partial since it's very similar to the SVS front mount

http://www.svspower.com/images/uploa...tudy_9_189.JPG

We added a substantial amount of heat wrap and it has worked very well. The heat wrap isn't cheap but well worth adding when making/using this kind of power.

Changing to the SRT intake makes it easier to configure everything for the front mount in the layout you've chose. Do you have room to get to all the spark plugs? It looks tight on the even bank cyl 2.

Why were the GT4094R's too small?

Did you dyno with them?

Well, your setup certainly inspired what I'm doing 100%. I took a long look at your case study and loved the badass no compromise design, so I had to do my take on it. Thanks for the tip on the wrap, will do. I can get at all the plugs. I'm concerned with cooling, the radiator I chose has the same volume as stock but much less cross sectional area. So I stuck one on the side in the fascia similar to what Paulo does with intercoolers, and I increased the oil cooler on the other side 2x from what I was using on my last turbo setup.

I'm even using a motor you guys built for a turbo kit you made, the one that was crashed and ended up in Canada.

Thanks for the comments.

-Dave.

I'm embarrassed to say I misread the compressor inducer/exducer size and thought that they were bigger than they are. A few guys on the forum noticed before it was too late and pointed it out, so I swapped.

GT4094R's will support over 800 each, or 2 x over 1600 HP! I realize the Viper is not as efficient, but that is a lot of power.

What size of exhaust housing were you using on the GT4094R's? – A/R

I am just trying to get a handle on the amount of power you are looking to get.

It looks cool!

Great work, should make some real good power no problem. Then after the break in and tune just need to get that power to the ground.
Speaking of that is this system using an AEM programer set up?

Yes, I will be using an AEM. I'm hoping someone here with a TT and AEM will be willing to share a tune or two to help me get it started ...... If I make any improvements I promise to share back with whoever helps!!!

best,
Dave.

Nice, between all the tuners there's plenty of AEM info out there they just have to want to share it.
I'd give Paolo a quick call on the matter and see what he can help you with setting up for a good tune, doing a front mount set ups himself of course.

Yeah...but the turbine maps read like crap for an engine that big.
