PHAMSPEED? 4th gen fbody anyone make their own hot side with ac?
A while back I saw a posting on fb, where a guy was selling a hot side setup he made, that retained the factory ac location.
He used the stock fbody manis.
Then This hot side piping went out of the stock manis, THEN UNDER THE STOCK K MEMBER, towards the front and into a t4 flange behind the radiator.
It kind of made it look like a Huron hot side setup where it mounts, If you know what I mean.
I wish I would have saved the pictures he posted of it.
Now for a lowered car, this isn’t idea at all.
I don’t recall if this was on his daily as a race car doesn’t need ac at a track,I’m assuming it was weekend warrior or daily car.
On an average height fbody what are your thoughts on this setup? I’m sure most exhausts hang lower that the 2” hot side piping tucked close to the k member.
This would be a ghetto turbo hot side ac retaining setup but may work.
Even if you can get an oval pipe vs a round pipe to give u more room from them hitting as some have done that before on exhausts or slightly crush 2.5” pipe to make it oval...
well im sure I’ll here all the negatives but it was something someone did.

Search for Phamspeed from about 10 or 15 years ago. It was a GREAT kit, only downside was the crossover and down pipe went under the K member, but EVERYTHING was in the stock location. I even managed to get the stock fans to fit in the stock location with some cutting.
you used to have this kit before?
Ill search for him tomorrow to check out the kit.
Yes, for years and years. It's still on the car currently with the current owner. Again, not the best for ground clearance, but if you're running 17/18's it wasn't bad and kept everything in the stock location. They haven't been around for a LONG time, but people should still have build threads, including me. They had 2 kits, 1 tubular and 1 stock manifold or any shorty header. I used powdercoated shorty's, but could have used stock manifolds without a problem.
2.5". I dug through some old pics of my build since Photobucket screwed all of us who've done build threads on this side years ago. I ran 18's and it really wasn't bad. Stock K member, stock A/C location, stock alternator location, stock fans (modified of course) and fit a Precision T76GTS. There was a brace from the crossover pipe to the A/C compressor bracket to support the turbo. This picture is circa 2006.
I don't know why a vendor has not taken this approach yet. This seems like the best packaging that only looks like it needs the alternator relocated up to clear a downpipe. https://ls1tech.com/forums/forced-in...lete-pics.html
Have you done it before? If you're on larger diameter wheels/tires its not an issue unless you plan on off roading the vehicle.
Who the heck runs larger overall diameter front tires? I been around a while i can tell you not many people. Bottom line is the k member is one of the lowest points on the front of the car. Putting a pipe under it would make the pipe literally 2 to 3 inches off the ground. For our roads around here you'd rip it off on one drive to work. Hence my opinion of the idea. I like thinking outside the box, i just dont think the room is there to do it reliably.

Not a taller front, less flex from a smaller sidewall (275/35/18 vs. 245/50/16). With a spacer on the bottom of the shock if gives you more ground clearance regardless of what size front you have. It worked great and would rarely scrape. I'd consider it all over again if someone made a kit for the right price. The entire hotside was a single piece, plus the manifolds. No relocating crap, no melting, etc.
Im not saying its the only way/right way to do it. It just an option for those who are ok with loss of ground clearance from stock but keep everything else factory.
The one I saw, had each pipe from the manifold go under the k member and merge into a t4 setup.
The phamspeed one does the crossover then a merge.
This one looked like a Huron speed v1 hot side setup but going under the K.
Using 2” tubing helps with ground clearance and 2” can support up to 1k horse power.
Or even using oval piping to get more clearance. More work also though welding it up.
maybe I should try this by making it out of mild steel and wrapping it up.
Another idea: the Stainless Works down and forward turbo headers. Their upswept ones ones also fit, but are 1-7/8 and require pretty much everything to be relocated. But the down and forward, fits and doesn't hit the shock tower and is the best way to avoid relocating anything and fitting whatever turbo you want. It's a 1-3/4" header as well and comes with either 3" or 2.5" collectors and v-bands if you want, best I can tell. You can install the turbo upside down in front of the engine with a pretty short crossover pipe and then run the downpipe either out the passenger fender or flip the turbo around and fab a downpipe to run outside the steering column using a BMR/MWC turbo k-member and out the back.
Why this hasn't been done is strange to me? I've thought about doing it actually. Also reduces the amount of hotside piping in the engine bay. I think cost is the major problem. $1400+crossover and downpipe fabrication. Also, I think the radiator has to be moved forward. Since the pipes are coming out near the top of the motor, that's where the radiator sits in the stock location. But still, running a stood-up radiator with some custom a/c lines is not a bad deal...
Where did the downpipe go? In place of the alternator?
I honestly don’t recall or remember. It’s been about a year since I saw this setup.
It mahe had a fender exit or dumpd after the turbo which isn’t too idea for a street car.
Jake, that’s too much modification for a street car with ac
