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

It's like shifting a manual with the intent to spin tires versus blipping the throttle to cushion the shift; the driveline hates violence.  It lives much longer with smoothness.

So what you're telling me is turning down tq management and upping line pressure shortens the life of these GM A6 trans? :meh:

No, you need the line pressure.  That helps longevity.  You also need to keep some torque management.  Just don't take it down to zero.  The more you leave, the longer it last.  But you don't get lightning quick shifts with 100% tq managment.  Mine is still pretty high, but I get a quick shift, just not violent.

It's looking like it's going to be hot tomorrow and one of the Street Outlaws guys will be there, so I'm guessing it will be crowded.  I'm probably going to wait another week.  I'm going to try to buy a new intercooler lid for my car too so another short setback.

While I had the blower off, might as well.....

 

I had a couple bent fins on the stock intercooler brick.  I'm slightly concerned that I'm starting to push too much air through it so it was time to upgrade.

I have to do some modification to it.  1. Reinforce the brick just like I did on the stock one.  This will prevent it from collapsing under boost.  I have to get a piece of aluminum to weld on to it.  2. I have to machine 1/4" of the ribs off the top of the lid so it doesn't rub on the hood.  3. Remove the restrictive ZL1 quick connect fittings and replace them with some 3/4" hose barbs.

First I cut the old fittings off flush, then used a 5/8" then to 3/4" drills to cut the remainder of the stock pressed in fitting out.

I'm going to a friends shop this afternoon to machine the lid and I have to re-fill my argon to do the welding tonight.

It's your fault.  You mentioned it the other night.

Machining done.  I have to weld the fittings and reinforcement plate on tomorrow and I should be ready to fire it back up.

I milled the water manifold back some also, so my fittings wouldn't be right up on the fuel rail.  And I ground out the big restriction in them.

These welds weren't so nice.  I can't get tons of cleaning on my tig.  I know this aluminum is a multi layer stack with layers of aluminum, flux and some solder like substance.  Maybe that's part of it, but other people seem  to weld it fine.

I have two options for hose routing, but I think I like the shorter route back to the HX in the bottom picture.  I bought some heat shrink hose clamps for the connections on the lid, so I'm waiting on those to button it up.

Probably not worth insulating the hoses?  That black will sure transfer the heat, soak it up from under the hood as well as sweat and drip.

The big heat exhanger bolted directly to the a/c condensor is a bigger heat soak problem.  Nothing is really a problem until you are sitting still in traffic or in the staging lanes at the track.

I got it all buttoned up and went for a short ride.  I hit it once and ran it up through 2nd gear.  It only seemed to pick up 1 psi of boost and I was expecting more.  I might have my bypass valve set wrong, so I'm going to check that.

These heat shrink hose clamps are nice.  Downside is they are one time use.

Well, seems that the blower port and throttle body was only worth about 1 psi. But somehow good enough for 3.5 mph.  DA was 1150, so a little better than LS fest, but not stellar yet.

Previous best was 6.79@103

Best mph.

Best ET.  Funny thing on this one, I spun pretty bad.  The track just wouldn't hold a hard launch.
