914-6/904 project begins Options

Rube Goldberg. Where you gonna bolt up the front of the top control arms?

[veekry9]

Lower cg,loads the lower control arm tube,the reinforcement simple channel and plate.

Rube Goldberg. Where you gonna bolt up the front of the top control arms?

Relevant question,the weights and balance data unresolved.
Less than a 914,lighter up front too,I would hazard a guess.
A set of scales to determine balance fore and aft,and the time tested leaner beams test to figure the height of the cg.
Everything is a trial and fit,slice and dice,seat of the pants,eyeballin,etc.
Go ahead,roll your own 904/14-6,it's good fer yuh.
As Phoenix-Mn said,a new moosetrap is invented every day. (IMG:style_emoticons/default/smile.gif)
Come to think of it,Adam,do you have a rollover rotisserie cage ala RD?
Handy for such computations,the numbers defining the handling of the 904.
It would have to be as good as the GTS or GT14,the point of the sweat.
Making a shortened Macpherson strut work in so little headroom is a tall order.(Porsche ruled them out early in the design stage)
Losing the strut and adopting uelws,allows some tuning of the camber gain and antidive the
genuine article benefited from,using all of the 165-15 tires.



Economy of scale,904/906 LH or RH.
Turned on a VDF tracer lathe,1963.
Similar bj seats to the 911.

Hey everyone, I don't need the motor I pulled out of the donor car. So it's FREE, pickup only at my shop in Ravena, NY.
Happy new Year-
Adam

Adam I am 20 minutes away. I'll take it.

That's a deal I'll take every time, Brett came through wen 5lbs of chili, thanks man! Glad the motor went to a good home.

3/4" plate-crs,jig for both axis level.Location pins (ball dim)variable.
Tack heavy,remove location tube,pins before final passes.
Adjustable ball to ball dim,(blue),and spindle height.
M10,M12 shoulder bolts.

As much as I hate the idea of cutting up a vintage IMSA car it looks like the center seat racer is a better start. I also really like Veekry9's suspension ideas. Very forward thinking and simplistic. (IMG:style_emoticons/default/assimilate.gif)

Glad you guys liked the chili. Was great to meet you guys and see some of the awesome cars you have there. Thanks again for the motor.

If you are going to mod the towers anyways. 944 and race coilovers. 20mm 911 rotors stock. All sorts of aftermarket everything. Or skip the coilover and make the 944 balljoint fit the 914 arm.

I plan to start playing with lowering the towers next week. I was able to salvage all the mounting points from the center seater so it should be smooth sailing.

[veekry9]

More fixturing.
What if you want to run a 225 tire,with a low profile radial carcass?
The spindle geometry is modified by moving the top ball inward.
The kingpin angle is thereby increased from 11 to 14* and the scrub radius is improved.
The spindle height can be increased,lowering the ride height from the factory 130mm.
Measure,measure,cut.

If you cut down the strut have you found a shorter insert yet?
If you're hoping to just shorten the top chassis mounting and use the stock length strut insert it will just bottom out.
The strut insert will bottom out if you lower the 914 too much, you can raise the spindle (thus lowering the car) a certain amount. Tangerine sells lowering struts.

Just a thought
why not something like below, except lose the top A-arm, keep the stock 914 A-arm, use a bare strut (no insert) for the spindle to the yoke in the pic and then lay the shock down like in the pic.
You can also keep the stock 914 torsion spring and then it's just a shock (with no coil spring) in the lay down config.

I'm going to roll the dice on the fact that the coil over have a lot of adjustment, so with a shorter strut and the adjustment I might be able to squeeze a few inches out. It's the cheapest route, so it should be the first. Also, the most simple. What I should probably do is send a limo full of Hooters girls to pick up veekry9 and bring him down here for a few weeks.

In the future,antigravity generators will allow the use of quaint vehicles of the 20th century as personal performance runabouts.

Nice work from the '20s-30s,front torsion bar suspension,front wheel drive.
The idea is the same,using the 914 lowers,strut,antirollbar,floorpan,brakes.
One constraint is the length of the torsion bars which will protrude from the 904 lower valance,I think.
A simple tubeframe to carry the forward ends of the control arms,bolted to receivers welded to the remaining sheetmetal.
Resolved the problem if shortening the torsion bars or tubes is necessary.

[Unobtanium-inc]

Good news, the guys at Elephant Racing got back to me and they have a plan that can squeeze at least two inches out of the struts. Stay tuned!

[veekry9]

That's entertainment!
Spectacular hooters sweety,ah,ah,are they real?

[Mueller]

I shortened my struts on my Volvo...Koni Race inserts are available in various shorter lengths.

Once welded up I added threaded collars to run Ø 2.5" springs.

[veekry9]

One would like to use as much of the donor 914 as possible,the emulation of the 904 running gear bringing the front geometry closer to the original.
Looking closely at the a arms here on the drawing you can see the rising camber design,it works real good.
One of the other issues is the rear trailing arm pivot point to axle cl with a lowered ride height.

Why not add another short strut where the vertical fixed arm is. This would double your compression distance and avoid a bottoming out of the single strut.

[mgp4591]

The vertical strut looks to be adjustable and probably has been adjusted to the compression length of the total travel. We'd have to have more information than what's presented to assume anything else... I'm assuming.
