Twin Turbo 5.7 Hemi in a Nordic V-Drive

[TurboNova]

We are building a 04 5.7 Hemi twin turbo to put into a Nordic V-drive. It will feature FAST XFI fuel injection to control the factory coils, use the factory crank and cam sensor. I got one of the first few Mopar Perofrmance MPI intakes. It will have a 90mm throttle body, air to water intercooler, twin 60mm ball bearing turbos, Tail 40mm or 44mm wastegates. We hope to make between 700-800hp with this combo.

Cool..

Here is another shot, we have the headers and exhaust done.

Real nice fab work Brian.
I'm glad to see I'm not the only one who has to put a small spacer in the pipes sometimes to make things line up.
The individual ignition coils sure looks like the way to go.
Does that allow you to run a larger plug gap since each coil has more saturation time ?
How could you retrofit an ignition setup like that and use 8 coils on something that had a distributor before ?

[TurboNova]

The washers are for the bolts that are too long for only mock up.
There are several ECUs that can fire coil on plug, FAST, Big Stuff 3, Motec, Autronic, wasted spark with Electromotive. These are just a few.
Fast and Big Stuff can use an electronic dist drive that will take your ignition signal and convert it to fire the seperate coils.

I was referring to the short sections in the header tubes.
The more I hear about the Big Stuff ECU the better it sounds.
The Haltech unit I've got has served me well but it doesn't have some of the features of the more expensive units. I guess that's why the Haltech is
only $ 1350.00
What do you think of the Simple Digital Systems unit ?

A couple of the honda guys have that who bring there cars to dyno, I have been far from impressed. Your Halltech is much better. If I were going to do a low cost solution it would be Megasquirt. You can buy the ECU for $500 done with a wire harness and map sensor. It is very close to what the FAST and Big Stuff 3 software is but also is not a plug and play style ECU. You will have to do alot of research on their support site to get things working and there are alot of bugs. You can't beat it for the price.

Looks like a small oil pan. Planning on making one that has more capacity?

[TurboNova]

That is in the works.

Lets see some pictures of the boat. Motor looks great!!!

looks good!!! and another turbo guy

Here is another pic after paint, the block is black with blue pearl, intake and elbow was powder coated black. I am waiting for the compressor covers to come back from the polisher.
Here is a link to one of the boat

You can go to my website and there are alot more pictures of this project. I try to keep it updated as much as possible.

Yaya! Looks hot to me... Nice headers! Who does your welding? ;)

Any estimate on HP and torque? Will be a cool motor and a little different!!

[TurboNova]

We are shooting for 700hp on a mostly stock engine, the only thing that will be different is the cam, springs and intake. Stock bottom end, stock heads.

[78DiMarco]

I hope that thing has forged pistons. I'm assuming it does. It should be a nice little package. Thanks

[RUSSO]

Any Updates??

[Jim W]

Oh come on guys----- the thing sucks azz!!!
Just look at that dip stick!!!!!! :rollside:
Keep going, totally cool.
Be good, jim

Turbo--what C.R. are you going to run....Pump gas? Nice work...whats next?....Steve

I am still waiting for the cam to be ground. We will re-work the pan before it is done, including the dipstick. The stock compression is about 9:1 on the new Hemi. Yes, we are planning on running pump gas with somewhere around 10psi after the dyno tune. Now we just have to get started on the boat. I took the Casale gear box apart yesterday, other than a little water inside, it looked good. We have two sets of turbos for the 5.7 the 74mm turbos that are on it and also two 66mm ball bearing turbos. We will try both of them on the engine dyno. Neither set of turbos will have water cooled exhaust housings. Next I want to build a 6.1 Hemi with a 16 coil EFI system that my friend builds so each plug will have it's own coil. The 6.1 also has piston oilers to help cool the pistons, perfect for Turbocharging.

Brian, For a low boost application why would you need to have the cam reground?
It seems like if the stock cam was not optimum for the application another # or two of boost would more than overcome any lacking in the cam.
I always questioned this about someone trying to optimise individual components like porting the heads or installing larger valves for a turbo engine when it's so east to just add enough boost to get the HP where you want it to be.

Comp Cams is doing some custom grind stuff on the 5.7 hemi for me. I don't really have to change it but after talking with my guy at Comp they got 60hp more with just a cam change on the stock engine. I am working with him to come up with a custom grind for a turbo hemi. I could just turn up the boost but if I can make as much power with lower boost it is easier on the engine. When people call the shop I always say the more horsepower you can make on the engine the more you can make with boost. So if you want to make 800hp, you can get that with less cam and heads at say 20psi but you could also get the same results at 10psi with better heads and cam ect.. I want to make around 700hp on pump gas so I need to make as much on the engine as possible so I don't have to run alot of boost to get there. If I don't then I will be looking into pistons and rings.
