Default What exactly is a Falconer ZR1?

Saw the pictures from Carlisle and Falconer Z. What is the deal with that engine?

the falconer is a v12 of approx 540 ci, 650+ hp, revs to the moon, but it's big, heavy and was just a one off "exercise"

car makes some very nice noises and goes pretty good. if you look at the 1990 road and track they did some tests

look up the ZR12 very interesting ride and I want to thank david and GM for arranging to have the unique rides there. it really added alot to the show

The car trapped 133 (!). I remember that clearly--I thought that was all the MPH in the world back then

"The Falconer" is a recurring Saturday Night Live sketch chronicling the adventures of former businessman Ken Mortimer (Will Forte), who left his job to become a hermit, living in the forest with his trusted pet falcon, Donald. The Falconer, who speaks in a loud, strident voice, routinely encounters trouble and sends his falcon to get help, who—in turn— often gets sidetracked along the way. One such adventure features Donald immersing himself in the modern society which Ken had rejected, wantonly indulging in every imaginable vice before returning to the forgiving Falconer.

Default falconer

If memory serves me right
back in 1990 when the falconer first appeared in carlise in the pavilion the explanitation was that the falconer v12 was made by engine builder ray falconer????not sure of first name.the guy there had said that gm wanted a compatible engine that would compete with the viper v10,although the lt5 was in production the falconer is actually longer to acomodate the aditional lengeth of the v10 and at that time the procudtion of this car
was uncertain as the price and need for 2 super vetts were not needed so the falconer faded away.
I have the pic somewhere with the placard that explains all this




later

That sounds like one hell of a project, I would have loved to hear one run. 133 trap speed, that is smoking!

george is right!! it was motor trend. trapping 133 indicates some pretty serious power, dwight traps up there and and putting down 570+

with the heavier car, this thing is likely doing over 600. I was also surprised to learn this big v12 can really rev, up to 8k!!!

What type of engine is it? Push rod... overhead cam? What's the displacement?

Looking at that picture of it, I'd think it couldn't be OHC. I would guess they were OHV motors.

It looks like a derivative of the 427 big block chevy; the bore and stroke is the same (4-1/4 X 3-3/4).

It's a 600 cu in pushrod engine. The V12 block is based on a Gen I small block Chevy V8 using the same 4.4" bore centers (which is why the engine is 8.8" longer), 9.025" deck height, bell housing bolt pattern, side engine mounts, and even front engine mounts. This particular engine uses the 4.125" bore and 3.75" stroke from the 400 cu in V8. Small block rods will interchange and you can even see the same water pump will bolt up here:
http://www.falconerengines.com/prod0...20for%20specs:
Although the intake and exhaust ports are different from the Gen I small block, the engine block retained the 5-bolt per cylinder head bolt pattern as you can see in the bottom picture the familiar row of head bolts below the exhaust ports.
Here's more info/detail here:
http://www.corvette.nl/specials/zr1v12.html
You can see the extra 8" added between the front wheel and front of the door and the extra space in front of the battery.
http://www.97vette.com/events/Museum2002/dscf1162.jpg
You can make out a little about the engine but this is clearer:
http://www.corvette.nl/pictures/zr12_3.jpg
The addition of the V12 engine plus the 8" stretch added less than 100 LBs to the weight of the car...pretty amazing!

You can still buy the V12 engine if you wanted to duplicate their effort.

The 427 big block uses a 3.76" stroke. Also, the bore of the V12 is 4.125", not 4.25". With a 4.4" bore center and sleeved aluminum block, a 4.25" bore would be impossible. The valve covers are wide like the big block but it uses the canted valves like the SB2 heads making it easy to be confused with a big block. But it is definitely a small block derivative.

Man, that's like a marriage of two of my favorite engines, the Oldsmobile Aurora IRL V8, and that intake looks quite similar to the gorgeous one that sits atop each of our cars.

I wonder if the blower is to offset the puny displacement and high revs of the N/A design (~650hp @10,000 rpms on methanol). Odd they used the 3.5L vs the earlier 4.0L engines, though by 2002 they had 180-degree cranks and were making about as much power as the 4.0's had.

Also, how freaking awesome would an intake like this look on an LT5?




Damn, why was I born with more brains than money?

That's been on the website for quite a while.....talked with Ryan (he's near the bayarea) a while back....very good engine builder and has a lots of knowledge on lt5's, probably for the same everyone else charges he can build one for sure. I'm not to big fan of added cylinders to a small block chevy, better than a mopar but not my kind of option.

Look at the difference in intake runner length...an you imagine trying to change out that alternator, or even better still install headers!

I wonder if the runners are because they just have to be that long. I believe that intake is straddling the roots blower.

On an IRL car, the exhaust would have been routed up, not down. I'm not gonna buy it, but I can fantasize can't I?

This was the car that got me fantasizing about the c4 back in early high school. I barely remember but it was featured in a 'tuner' corvette article and it was something like a 9.9 litre v-12. Basically 2 extra cylinders grafted to the front of a traditional small block. I really loved how the car looked stretched at the front between the tire and windshield. Sexiest c4 of all time imo.
