1970 Coronet Super Bee a.k.a Project Plan Bee

[SuperB70]

Hey all,
Happy new year 2022.

First, bare with my english, I live in Finland. The land of SISU,
also country with most world champions in motorsports and of course Santa Claus = Father Christmas = Joulupukki .

I thought its time to post my project.

Bought as a roller, disassembled left to rot, father-son project from South Carolina about 10 years ago. Then it sat in my yard for years. Been slow going project for past 6-7 years now.
Running own fabrication shop and building customer cars took toll on my own. I also make custom cooling products, you will see that in this.

Now past 5 years been working as hired help, been more time to build this. Now days work as an foreman at local trade school machineshop. Have almost all the equipment it the world to make my parts.

SO I started looking one years earlier for new project.
Vision was some how clear. To build really one off, powerful Grand Tourer. Been saing that I'm driving it gross Europe to Monaco when its done.

It will be low, has hidden tube frame inside its body, inside roof frame,
inside frame rails, double rails at rockers and in the middle, around transmission and drive shaft.
Removable main hope, criss and door bars.
Many body panels will be hand made from aluminium.
Fluss front and back glass, one piece door glass.
As you can see in the photos, body has cutted / drilled open,
brassed and sandblasted with home made retossorie, then I put my frame table together
and installed body on it so that top of the table as ground,
ride hight set to 4", as you can see, front rails dont work with that.
They may be relocating or changing

Engine: Brand new gen 3 Viper 8.3L, (how many knows that its build by ILMOR)
Modified Ilmor crank, my own tool steel main caps,
custom made one off Auto-Verdi connecting rods, Diamond pistons,
Autoverdi 5 stage drysump pump, custom ATI super damber,
ported heads, custom cam, home build intake manifold
with (+2000hp) water to air intercooler,
two cores stacked in one set off head plates. 4"x4"x20"
4.9L Kenne Bell twin screw supercharger,
twin 102mm electric throttle bodies and much more.
Almost all one off custom pieces.

ECU and Fuel:

Maxxecu Pro-ecu, seq fuel with 10x1500cc/min Bosch EV-14 injectors,
Aeromotive 6 gal/min mechanic fuel pump,
seqvental ignition, coil per cyl.
Ecu controlled boost control. (secret stuff still)

Cooling:

Total of 12 cores, all the usual and then some.
Even some experimental stuff.

Transmission:

Reactor product custom made SFI flexplate,
build Mercedes W5A900 trans out of 57 Maybach,
(same used in SLRMcLaren Mercedes),
my own adapter/midplate, paddles, OFGear controller.

Following for updates

[WSSix]

Sounds like it's going to be an amazing project. These cars are so cool since you simply don't see them often let alone modified like you have planned. Best of luck and keep us update.

Interested

Always had a thing for the 70 Bee...I'm looking forward to watching the progress of your build.I had a 70 383 4spd Roadrunner about 6-7 years ago so I have a soft spot for those b body cars...cheers

Wow is this an awesome build.

Thank you for sharing this build.

Front fender time.

Since I moved front axle 3" forward, I need to modified my steel fenders to fit.
And with 19" wheels, stock wheel arches (for 14") doesent fit quite right.
Now is good time to make the chances, plan how to cut is critical.
Want to keep side markers, one thing that makes musclr car different than our "normal" euro- or japanise cars.
New wheels and modded frame forged me to rise arches 2" to clear wheel when turning. Also arches looked tobe little too long for my taste so I nipped 1" way from the middle. That turned me to add 4" add the back cut line.

Good fitment, tig welding, relentless hammer and dolly work and you dont see the seams anymore. I could slap and shrink them to smooth but why? they will get coated/ bondo'ed (even thin skin)/painted anyway.
Driver side fender have had some kind of fender bender so I chanced front part, so many screw pulley hammer hoses that no point to weld them.

In one pic you can see how I fix are when it has got "fed up" cant shrink anymore. Cut round circle out and weld new piece. Try to avoid sharp corners. Doesent shrank so much...

Is it just me or those 19" wheels and 15" rotors dont look that (mean too) big anymore...

Now I can start planning side skirts.. Dont want too much but want something.. One idea is to make Viper like side exhaust inside rockers... Mufflers, yes you guested. Have to be made...

Again, I will leave something coming to last pic.

After I made brakets and bolded fender on, I realized: HOLLY CRAP!!
there will be 90cm (3ft!!) from grill to water pump pulley..
I have some real estate for my serios cooling systems...
Tell me, should I post teaser, what I have come up..

up to next one..

[Dave Pratt]

Damn! Fantastic fab work and then some.Love this build...

[SuperB70]

Lets start to build the intake manifold.
After extensive searches I was not able to find anything like this been made.
So first one of its kind. Same sad Kenne Bell and few twin screw specialist from Sweden witch turns out to be great help in this.
Twin screw supercharger was invented in Sweden by Alf Lysholm.
Thats why all twin screws are referred to as "Lysholms"
But Kenne Bell is the only one with Lysholms/Autorotors idea, with 6 by 4 rotor pack design. Far superior to others in my mind.
I feel lucky, as I've had a chance to visit supercharger factory three times.

You will found out that this build is highly dependent of friends..
Man, it good to have alot of skilled friends..

First I set the blower on the engine with piece of I-beam..just to get visual reference.

At that point I had 4.2L blower, witch I did installed to 572 Hemi. But thats another story.

Next I started to draw 1:1 scale plan what kind it need to be.
What kind of air space will I need and get.
Bottom floor spoilers where an a idea but tno needed them.
I already had my special made intercooler core arrived from Europen core factory.
I ordered it as 2 stack 50mmx100mmx500mm( 2"x4"x25")
So it will have two cool shocks, instead of one thicher core. That could suffer from heat soak more.
Capacity to cool over 2000Hp.
With ambient cooled water/coolant.
On the sided I need space for Bosch Ev-14 (1500cc) injectors, one per cylinder.

Under the stock intake is coil packs, couple knock sensors and some cast bosses. They all need to go or atleast relocate.

First plan was to machine it out of 6061 billet, thanks to near by top cnc shop. again one of my friend worked there as sales manager. But when he quit, so did my hopes for billet intake.

Next idea was to make molds and cast it from aluminium with yet another friend. Hes been doing molds and casting (mainly stainless) past 20+ year.

We where just about to start fabbing the molds when yet another friend offered to help. He has huge new cnc-press brake. 100.000t, that 1 million kilograms. 2mil lbs.
So we made the base plate with that. From fresh 10mm plate.
Bend it like it was A4 printer paper. LoL
But right on the money. Great!
I was educated that aluminium ages, old plate brakes..

Now I've made welding jig, from 15x150mm I bean, cutted in half, welded it to 50x100 with 6mm wall bottom tubes.
Will fit to my powder coating oven for pre-heating.

Next cutting front and back plates from 10mm plate and injector bases from 50x50x10mm L-bar.

and I still have just a few details to figure out..My design lives...All the time..
