What would you hypothetically build? Now with more CTS-V

A little fab work from yesterday.  My headers have gotten to where they leak at the collector all the time.  I can tighten them up and they are quiet for about 2 weeks then they sound like an old truck.  So, I cut them off and I'm welding V-bands on instead of the ball and socket.  I got as far as getting the headers bolted back on last night.  I'll modify and weld up the x-pipe tonight.

If you look close you can see where the flange was sliding up/ deforming the ball on the header.  They moved a little each time, just getting worse and worse.  The flange piece needs a bevel on it to distribute load, but what can you expect for $2k headers. :smirk:

BTW... What brand headers were those again?

I noticed Kooks went to a different clamp setup. Probably to stop that from happening.

Hope the new style don't leak!

The X-pipe is fit up and half welded.  I'll finish welding it this week.  I'm going to weld up all the joints in it also because each one leaks a little bit.  I'm also going to put some wide band clamp on the X to stock muffler joint so hopefully that will seal that joint completely.  If not, that might get V-bands also.

I made my intercooler pump mount tonight.  No shot of the cad, but I drew it up there first and printed it 1:1.

Then taped to some .090" 5052 aluminum.  I marked the hole centers.  And traced the outline.

Drilled the holes.

Then cut it out with a jigsaw.

Then rounded the edges and DA sanded the plate.

Installed the ZR1 pump bushings.

I have to get the correct bolts tomorrow.

It's about the same size as the varimax.

I'm tackling a project that was low priority last year, but I'm out of the high priority stuff now.  I've suspected the upper control arm bushings were bad for a while.  It's a relatively common problem and they squeak when it's real cold outside.  I actually bought poly bushings last year to do this, but didn't want to mess up the alignment to do them since it wasn't a serious issue.

Tore it down.

I even pulled the spindle/hub for another fabrication project.

Yep, bushings are bad.

New creative steel "street" bushings to go in their place.

Beginning work on the brake cooling duct plates.

Cleaned up the spindle and threw it back on for measurements.

Got some measurements and drew it up in cad.  I'll have a local shop laser cut the backing plate in 18 gauge 304 stainless.  The "appendage" hanging off the bottom is the incorporation of the factory shield that covers the ball joint boot from brake heat.  This plate will replace that part that is currently sandwiched between the bearing and spindle/knuckle.
