Better than a Volvo

[DaBlist]

Was on Turbobrick's and spotted this 1200 in the back ground.

Is it on here or anybody no more about it?

 

 

 

And if you see me, kick me for selling mine, stupid, stupid, stupid

   The 1200 coupe is own by Jeff Leclerc. He races with Willamette Motor Club, http://www.wmclub.org/autocross.shtml

Here are some photos I took at Maryhill, WA  at the Maryhill Hill Climb, Sept 6th and 7th 2014.

 

Plexiglass windows rear and sides, well it's a race car. Jeff said after Maryhill he was removing the rotary engine and trans and the car would be for sale $3500.00-$4000.00

OK Y'all, them be the facts! Your job is to hunt down Mr. Leclerc

More of the Orange 1200 Please?

Shit Damn

From Sept 2012 at McKay High School auto-X

That's all y'all! NO More!

This was my first auto-x with SMURF and that's Barry's blue 1200 coupe, A14 he raced Maryhill this year and left the course due to a burst heater hose. Very lucky, about 15ft down over the edge-NO photos, I was working the corner 2 station down the hill. Towing truck pulled him up, he started the car and took it down the hill, raced the next day.

Thanks Morrison for the pics!

[graveltrapp]

Any vids of this running the hill climb? I would love to hear the scream of the rotary while looking at the sexy curves of a coupe.

[Morrisun]

No videos, officials want you doing you doing your job- cars were running about 30-35 seconds apart, not much time for filming on one or two corners!

So who contacted Jeff, and what price??

[DaBlist]

I love it!

But I like license plates, roll up windows, wipers, and a heater. You know, the necessities of us modern feminized men that like to drive on the street here in the NW

I know very little about race cars. What is the purpose of the coiled over shocks mounted in the rear seat area?

[DaBlist]

Maybe ease of adjustment?

[graveltrapp]

Must have some sort of 4 link setup in rear? Shocks seem awefully close together, and I dont see any fulcrums for shock linkage.

Any input here Papa Smurf?

Here is what I think might be going on.

[Aaron Datsun]

That volvo is awesome...I have contributed nothing to this conversation

[datsunfreak]

I'd say that's exactly what is going on.  Cantilevered shocks.  :thumbup:

 

Here is what I think might be going on.

[Morrisun]

The pivots, at the top end of the shocks, mounted to the gray horizontal bar running across the back of the car, attached to links that come up from the ends of the rear end housing. Notice that center link, or pinion snubber, runs forward to the multi-hole brackets for pinion angle adjustment. A 3 link suspension. Jeff did a lot of engineering, fabrication and welding to get this to work correctly.

 

Papa Smurf? I would come back with some witty retort, however I am saving my good conduct points for the slaying of the trolling ZEN...it's an exit strategy!

[Mattndew76]

Doing these type of mods add weight but open up huge lists of coil overs you could use. Ease of adjust-ability is an obvious gain. I would like to explore this using Air Ride parts.

[Morrisun]

Matt, weight in the back of a 1200 isn't really a bad thing, switch to a 3 or 4 link rear end set-up would make air bags easy. A 210 rear suspension set-up would eliminate the need for a Watts link or Panhard bar, as it uses a triangle or tri-bar configuration. More than one 1200 guy has thought about this because of the adjust-ability of coil over springs and adjustable shocks.

[Mattndew76]

I have been exploring all sorts of configs.

 

Gotta get a good rear axle setup or swap in a IRS. Lots to think about.

 

Still exploring the custom IRS with billet bits.

Probably get in trouble for saying this, but a 510 IRS ain't that hard...   ^_^

[Morrisun]

As a personal point of ponder, what does a 510 IRS assembly weight? Minus the wheels and tires of course.

[Mattndew76]

I want to get just a R160 diff with a LSD and rear spindles. I can make the rest.

[datsunfreak]

As a personal point of ponder, what does a 510 IRS assembly weight? Minus the wheels and tires of course.

 

About 15 pounds more than the complete 1200 rear axle assembly, and about 10 pounds more than the B210 rear axle assembly. 

 

Sorry, but I don't recall the exact numbers, just the differences. 

[Morrisun]

datsunfreak, thank you for the info. It explains why such a rear-end swap is so desirable for a 1200 install, a great deal less of UN-sprung weight as well as the handling of IRS in small nimble car.

 

As far Volvo's, this my favorite- 1967 with LS1 engine and a whole lot of cool engineering.

There are other videos of this car but this practice one- well you"ll see.

I'll let you know in a few months whether it's actually better or not...   ^_^

 

On the track (super smooth)  I would wager you'd see almost no difference. Where IRS is really better than a leaf-sprung live axle is on a road surface that's less than perfect. And I'd also bet ride quality is improved.

 

Even though I did the IRS in my car, I think the 210's 4-link live axle is the best way to go for a 1200 that sees a lot of track/autocross duty. I mainly just wanted to be able to adjust the alignment settings to my liking. The reduction in unsprung weight is just a bonus.
