Nice!

BTW, has anyone had experience with the OMP or Sparco rollcages? They look nice. Here, there is this brand called Autopower. Their cage mounts to the flooboard :roll: .

I've seen some real nice fabbed ones on alfapower.nu. I wish they could just send me all the bends, I can have it welded up here.

My car only has a custom bolt on rear rollbar. Maybe if I am serious about racing I'll add the front section.

BTW Dennis, did you see the video of "Marc7eleven" on youtube? It was at Spa, not sure if this was the same event that you went to. Sounds like a well built TS.

My original roll cage is from OMP. Nothing bad to say about it. I had to tune it later due to changed rules (thicker main hoop, etc).

I thought that was the swaybar (because I couldn't see the steering column)

Edit: Looked again and saw the steering column (and rack)

That was the same event (Marc won the races in our class). Marc was in the same team as me. He has a really great carb engine with about 200 hp and 250 nm of torque. Great modified suspension on that car. The package works great and Marc really drives well.

250Nm? Is he a wizard?

Yeah, on a carb engine. Very 1970-ish. :wink:

Dennis,

Those 147 GTA Cup 2.0L. How much bhp do they put out? Well driven 75s still can't seem to keep up despite them being FWD.

OK I need to drive at Spa and the ring.

When is the next trip? :lol:

Cage in various stages of completion...

Also, stitch-welding details, corners before gussets, engine-bay reinforcements (similar to Jes' car), "NASCAR-style" door relieves (for the fat-guy) and the upper-shock mount strengthening (for coil-overs and no torsion-bars...)

Few more...

Ah John,I see you had to kink the cage at the doors so your fat ass will fit... :wink: :D :D :D :D

Nice project bud..Are you not impatient to get her done?

Not trying to bash your obvious serious project or anything but why did you bend/kink the pipes in the door? Looks like it will make the bars "softer" in an impact and the mechanics involved will try to bend the pipes inboard hingeing around the main hoop and push that part that goes next to the B-pillar int yuor torso/pelvic area. Not nice.

I know they all do it in CRASCHCAR ( :wink: ) but I have never seen it in any other series (or country). It would not pass a tech inspection here.

Not to mention they don't add a whole lot of stiffness?

A comment on the stitch welding and cage.

To do it right you need to do > 50% welding. And not only on places were forces are introduced! But along the path the forces take into the chassis.

The same route I would take with building a cage (steel in the path off the forces).
Primary: A cage is there to ensure your own safety.
But a well designed cage has also the steel in the places where you add stiffness to your chassis and still ads a minimum of weight.
In the real world everything is a compromise so it is not that simple.
But just adding sturdy tubes doesn't help if they are added to the chassis on a thin membrane or act as a hinge.
