yah,them chems really constipated me a few weeks ago,so,I was like full of kot.

Yeah I drew it first,then I made them.Simple.



When I was younger,working the clay.
A repertoire of excellence.



An abundance of these are available in South America,go get some. (IMG:style_emoticons/default/biggrin.gif)

"the Red Fox has a long nose"
The snout is no longer than the factory baby bumpers.
An aero tray to direct high pressure to the rear,avoiding the (pressure) differential below the racer.
I noted this day that the builder has installed bench upholstery,likely to gain more headroom with the helmet.I might like the same treatment to shed some kilos.
A righthooker for the Cooper nose job,in extreme proportion.



In blue,a simply formed variation to punch the air,reducing the apparent flat plate area.
Make faster with the same power. (IMG:style_emoticons/default/evilgrin.gif)

A chalkboard was used to express the idea.

As per drawing,5L-V12 Longitudinal.



The actual Countach we drooled on at the show in TO,I recalled the fitment of the frunk,so I 'repaired' it in Gimp.I even like the color,new in 69.

A longitudinal mid. (IMG:style_emoticons/default/biggrin.gif)

The wing is the thing.
A much larger derriere,the proportions remain similar to original measure.

A forlorn 924/944 resurrected as a mid,a difficult transition.
Looks neat tho. (IMG:style_emoticons/default/smile.gif)

Checking the ads for a cheep 944,engineless.

Outside of the box,a real Porsche.Turbo'd n Chilled (IMG:style_emoticons/default/biggrin.gif) It is however,still front engine!

The wing is the thing.
A much larger derriere,the proportions remain similar to original measure.

The engine lid is at the wrong angle. It also looks rather smaller in scale than the rest of the car.

Unless it's sporting a super-narrow engine tilted up oddly?

Ya,I put it there to be visible at the viewpoint of the drawing,so the fan was visible,the injector covers are merely decorative.
While I was working on an 8,a 12 came up.An x configuration,solves a couple of problems and creates others.Seems workable tho.
(720/6)/2=60*.An unusual layout made more viable by the 15* VR6.(Quote:You can't do ....).
No overnight sensation,this is a long term project with plenty of challenges.Like how do you incorporate a vvt layout with only 4 cams?

New metallurgy allows significant weight loss,thermal conductivity improved.


A set of cylinders of minimum mass.

Pretty Pix of the computer model of the X12.



Used sbc dimensions for the rods,etc.This is a huge displacement,4.25 bore x 3 stroke.
4.06" Bore X 2.5" Stroke=427"/7L

80's build...... (IMG:style_emoticons/default/driving.gif)

[veekry9]

Sure,this is at the root of the Martian9 body.
One of the drawbacks is the aero drag,can't install the heavy door bars and have windows that move.
Certainly a much simpler approach,one that has worked well in the past and looks acceptable now.
My endeavor is the smooth-sided with the massive scoops and intercoolers,maintaining the cg of a mid.
The effect of the weight of the rads up front can be tested by simply filling a pail of water and swinging it about at 140mph.
The other purpose of the large (TR)side scoops is to fill the rear of the targa,reducing induced drag,with the fan.
The major surgery and workload doesn't put me off at all,as some of my work related jobs took 8+ months to complete(turbines).
The doorskins are fair game for my plans,and may be subject to a material change,to make more light.Patient,critical design.
The only criticism I have is the spoiler,which,of course,is not effective at all,reminiscent of ricer additions to compact sedans.
A more radical change to the concept of adding great power,calls for a serious rollcage and the addition of lightweight components.
A watercooled engine requires I include radiators,intercoolers,hoses,pumps and fans.By confining the added mass to the central
regions of the wheelbase,the cg can be maintained,instead of the 'dumbell' additions at each end,with their larger moments of inertia.

Siamesed Int ports,helical



Chambers,Seat bores

Add some reflections



Appears to be a pair of 60* V6's sharing a common 6 pin crank.
More accurately, a pair of sixes 60* apart,meeting an even fire order.



Right side view,a simple shoebox head,4valve.



Angular view,with case ribs and studs,head studs,Mbearing webs






Some top views,showing the offsets of each bank,shorter than the v or flat arrangments.
The short stroke and large Mbearing dia allows an ample pin overlap.

80's build...... (IMG:style_emoticons/default/driving.gif)

At first I didn't know what to think of that body mod, but the more I saw of it over at Genes the more I liked it and if the money was here at the time it might have been mine! We researched the kit and never really found out whether it's a one-off or a kit you can still buy but with a little work it will look sharp! The lines are definitely there and it even suggests lines of the Carrera GT to a degree- have you done any research on it to find out where the parts came from?

its a one off CA. 80's build.. running driving,,,914-6

An exercise in ic design,you know,like roll your own. (IMG:style_emoticons/default/biggrin.gif)
An aircooled 12 cylinder to fit inside the 914 envelope,a proposal that the 917 engine cannot meet.
Note the raised cam towers ala Julius Mackerle's Tatra.A vvt setup not available to the designers in '58-69.
https://en.wikipedia.org/wiki/Julius_Mackerle
Lightening up on the reciprocating parts and some elements from this decade makes for a viable -12.
A liquid cooled set of heads makes a 4valve arrangement possible,reducing mass of the valves for a given area.
A convenient feature is the proximity of the exhaust ports for a turboed variant,upping the ante for ultimate power levels of a Nurburgring endurance trackster.
The above pix is a simple Corvair version limited by all of the original factors of that design.


This is a 290 Cummins roller cam follower,cast.
