[SuperB70]

Lets talk little about this oddfire odd engine.

I was close to use 6.1 Hemi for this. But when opportunity to buy this dropped to my lap, choice was made. Hemi was put to side (for wife Challenger project). First idea was to use couple Holset-custom turbos. I've taken partin gen 2 twin turbo build earlier, so I know what kind of power and tq numbers these monster will put out, easilly.
But my love to twin screws starts back at 2000. I was in Florida, looking would I relocate there to live. My cousins friend had supercharged street race Fox-body Mustang. That was a wild ride. I've builded turbo- and roots blown engines since '93.
So I made decision that I should do what I advice other to do.

So started to do research and quickly found that Roe-racing was only one.
But they didnt have intercooler and used small head unit (mainly because bigger ones didnt fit under Vipers hood.) My good friend Johan (poweredbyjohan.com) in Sweden, has gen 2 with Roe kit. Same guy was in US tour with his blood red '68 Charger RTR. Viper has 750hp, witch is plenty for street car. But ofcourse I wanted more.

Idea came to build my own intake, with custom two row core. (I build custom cooling systems, European factory hand makes cores for me.). So I drawed up the needed core size and asked factory to build it as high power as size allows. They calculated that this core will support 2200hp. ( w/ ambient cooled coolant temps with front mounted heat exchanger)

Then came time to get strong enough parts. Main caps was no brainer. Those where made by my friend with cncmill, from our local steel. Imatra Imaroc (Moc) 410m tool steel. Tolerances where left tight, little left to line bore and hone. ARP hardware is used.
Was looking for stroker crank but ($6000+shipping) was out of my budget. Here no one was interested to off set grind the stock crank, more cubs that way. (I've two stock ones). Fixed the oiling problem same time. Actually I do that for a lot around Scandinavia. I'm known to do that. Customers from Finland, Sweden, Estonia, Russia.
Looked around for con.rods. Twin screw is second hardest to beat rods.
Cylinder pressures are high from low rpm. I called around the world,literally.
Stopped calls at legendary Auto-Verdi, in Sweden. Company that makes rods for ex. Nascar, NHRA Pro-stock, Porsche classes, Köenigsegg and F1 power boats. (autoverdi.com)
Stefan was really cool and helpful guy. He was ready to help me after I told what I was building. After all, no one has ever done this. He was sure he can make me a set of forged billed rods that could handle 200hp/each. More than enough.
So I packed block, crank, one rod-piston set and all other needed so they can rotate and calculate what can be done.
Roadtrip took me 4 days, 2 ferry rides. But it was forth it. After talked with Stefan, I desided to turn my engine to dry sump.
After all Auto-Verdi also makes world best dry sump pumps. Those also are used by the PROs around the world.
Time that engine was in Stefans shop, I cut'd resently builded front frame off again and started to plan a new, wider one.

At first picture is Kenne Bells 4.2L unit, but after I visited the supercharger factory and talked about my project, showed my custom intercooler core I came back with their newer, bigger 4.7L head unit. Got really good information about intake design and cooling system. Have revisited them few time after that one. They are following this with great intress. I have some new, never seen stuff coming.. Funny story about my IC core, I'd give it ispection to boss man. He looked it long and closely. Asked where did I get my it. Chinish one, perhaps? He sad that after 3 decades he havent seen one like that. Not sure was I really smart or stupid...

Stick around and we both will see that..

Last pic show how you can spot 4.7 and new 4.9L head units. They have already build in watermeth injection nozzle port.
