Jon at Huron was able to order me the AC line components needed to convert the C5 to the CTS compressor. Stout lines made by AP Air Inc out of California. They look to be several set pieces for a kit with them. I'd still go to Huron for the business as I did but these parts do show the assembly part numbers. The canister looks to have been welded with the correct adapter. The stand alone threaded adapter in the foreground I have not a clue where it might go yet, but I'll figure it out when I look at the car or review install instructions.
You can also relocate the compressor to the top of the motor if you choose to.
One of my next questions is going to be routing for the air intakes/filters. It may just be what it is as we divert funds to the baby and I'll come back to it, but when all is said and done I'd like to have the filters and pipes not be visible. Mounting the compressor high prompted that thought again. Though I don't feel like spending another $250 on different AC lines again.
I'm having enough issue and going slow just doing some basic things right now. A few more hurdles and then I expect we'll see easier progress.

Yes. My project began as a nearly 1k rw goal with the SC combo on MAX with methanol. I have humbled since starting that trek and would be fully happy with 500rw most days to slap around which my engine alone ought to be near. Going turbo has been an exercise in learning new tech for me though it has added at least one year or more to the project because I switched gears. Still..... power by gear remains my goal and my interest and I want to see that through. Whatever number it hits on a piece of paper will be interesting to see scientifically but I will be operating the car 90% of the time at low boost. The 6466 combo? I have had to trust the wisdom of others as far as sizing to the need. I have no experience to draw on with turbos. The brand themselves have a rep for faster spool. They are dual ball bearing. And another extent of unknown variables to me being cam specs when you get deep into the four stroke science when turbos are applied is something where I handed the reins to Bret in full trust and the spec he's been using helps spool faster.
For everything I DO fully understand, I don't really know how to anticipate this combo coming out in the end but I am really eager to find out!

You've got my number to discuss but I don't think it'll be any kind of major undertaking. If needed I could fab up a 4" round tube to a shallower oval and back, to get you between the frame and cradle. you'll likely not need to relocate the compressor to the top for this job. I've got a car in the shop now that's got the air filters in the A arms using come convoluted plastic tubing. Not my design or doing but it seems to work OK.

These turbos are going to light off as quickly as you could possibly imagine due to both the turbo and camshaft selection. With the Haltech, you're going to go beyond boost by speed. You'll be able to have a complete 3-D boost map for each gear in the car, along with fuel and spark advance offsets vs gear. You're going to have an amazing car to enjoy once it's completed.
the sophisticated boost by speed and advanced traction control are woth the price of admission if you want to stay pointed in the right direction
bret puts down some amazing levels of power
I may not need to go zero to jail quite that quick but the engineering is impressive indeed
now the quest is the fold and the best way to get rich so I can afford all of it
I told the ms that when I hit my number, new zr-1 is loking good for the old zr-1 prez and to keep the lsv company
1064 from the good ol general takes some stones I didn't think they had left from the good ol days
even more impressive would be to set FIA 24 hour record.
The vw nardo has it now at a no joke 201
back in 1990 the zr-1 did it with a factory lt5 paint blem engine pulled off the line because it didn't look good
thar car is still in the corvette museum in BG and didn't fall into the hole (snniff sniff, I sat there many years but many rare vettes bit the big one
time to do it again FIA is run what you brung and hope you brung enough
ave 201 over the 24 is movin it Chevy needs to show that a fancy bug has no place on the nardo ring and bump it
ez to say, very hard to do. Many big names ried and broke The old morton meteor had an aircraft engine to go 163
the factory 2025 zr-1 has a 233 top end speed. Pretty bold Not sure it can go the distance as its a mean feat
Sadly, GM backed out of FIA/WEC as a factory sponsor. Gentleman drivers and private teams can still run their own, but it changes the interest.
Excuse my pending rant: I do NOT understand their decision to push Cuds (my term for Cadillacs) into any racing environment as a factory effort. Everyone I know associates cuds with inner city SUVs after the last two decades of marketing to that target. I live in central Connecticut in a town where many founding families of this country sprung up (read: old money) and within a short drive to one of the most heinously rich and opulent parts of the entire WORLD and I can tell you that while I HAVE seen two V-series suvs.... I do NOT see anyone in the requisite wealthy marketplace buying cuds in any significance. I've not seen a sedan since before Covid. I've not seen a new SUV other than the Vs. The Boomers are not buying them. The city market moved on to other brands. The relative market share for cuds must be dropping compared the the more reactionary and innovative products offered by other brands. Not least of which also being that some of the lower tier models offered within the GM family of the comparable products.... LOOK better, still cost insane numbers, offer the same option packages or more variation actually, and have an approachable image now. My sister is on her second new $110,000 Tahoe for example. I would just really like to know what the key points of discussion were to drive cuds out in front of the Corvette or Chevrolet's good name.
not your daddy's caddy is it ? So when does a caddy get a stick but the vette not Well according to gm stick is obsolete but there is still heavy use in racing and if I had the $$ ready to go Bret's murder box would be going into the doomsday build
very impressive gear box indeed that will handle all the oof dah you can throw at it
as it is, the 1200 hp 4l65e will get the knod as it's something I caqn afford and even with spares, it will hold up well on street tires but not so well on yno or track
I have a 480le and can make the big power but it takes a fair amount of fold to go that way too. Maybe too much The limits there are much higher but there again, it takes too much fold for the fun
the HPT turbos are the bomb a bit pricey but super well made and fit the buy once cry once motto
I think Bret's recommendation of thew 64/66 HPE is indeed about right. He explained compressor maps and keeping the turbos happy at the right flow and backpressur
the huron has a nice 3" exh, and "it can' flow too good" as it helps the spool which should be like lightning even with the size of the hairdryers
As Brett said the cam, and combo match will spool like gangbusters and the Haltech rides in like a hero keeping all under control
I switched to a truck compressor on mine. I could not get the a/c lines to clear the frame. I also lengthened the line from the dryer to the compressor so it could have more distance from the intake piping.
Those are the lines and compressor I ended up with to cure my headaches. Have to swap pigtail on compressor and its got an extra rib or 2 on the pulley that isnt used.
Edit: That company can make custom fittings like the ones in the attachment for the CTSV compressor, I dont remember anything about the CTS fittings now. They just didnt have any when I called and no ETA and I didnt want to wait. May have been during Covid so who knows when **** would have showed up. Theyre local to me and very helpful with what I needed when I called. Itll be a good contact to have if you run into issues with anything. At least you know theres options.
Ah. I see. I could potentially use the other adapters to have the hose come in from the front then. I wonder if I would have sufficient length of hose.
Made your own lines, or have someone nearby who can? Which compressor part number was that?
OH boy am I not looking forward to finding out things don't clear the frame if that's the case.
Those adapters are pushing the connections way too far out. We could certainly find some really shallow connectors. Secondly, we could also get some hard 90° fittings which would allow you to run a straight hose connector. I could also help you with making any line you need. Don't sweat it!
