I am posting these pictures for 78Macho. This is his motor prior to being installed. I am sure most of you would agree with me when I say it is a beauty and it definitely will serve as my inspiration as I work towards my TurboForce install.

Really, really nice work!

BTW, there's nothing wrong with the "version-2" (welded) air bonnet pictured, it flows about as good as the "version-3" (fully cast) and a really nice job was done making it look super!

When the owner raises the hood at a car show, jaws will drop.

I really like those pix. It gives me ideas and inspiration as to how I will plumb my own setup.

That setup looks almost like a bolt on kit, like the Ford/Chevy guys enjoy!

Awesome!

That's the way Pontiac should have done it in 1977!

Wonder how things would have developed if Pontiac did the turbos on the 400 instead of the 301?

It may have even passed then current emissions/MPG requirements, so no need to abandon the 400?

It was a bolt-on kit. It was engineered and sold by H-O Racing Specialties in 1977 and later. See here for details:

Of course this kit is no longer available, so don't even ask.

Just showing the simplicity of the layout was enjoyable. I also really liked the turbo mount flange. I had been wondering how I was going to make things fit AND have a place for an a/c compressor. And then I saw your setup with an A6, so I know it can be done with a piddly little Sanden!

BTW, what is the function of the throttle shaft pressurizing plate thingy?

It's cool you guys did it with the q-jet. Everybody seems to do the Holley double pumper mod. How tough was it to get the qjet tuned properly?

Pressurizing the throttle shafts seals a path so the boosted air/fuel will not escape the confines of the carburetor. Same deal with the accelerator pump. You don't want boosted air/fuel blowing all over the engine!

The Holley has fewer escape paths for boosted air & fuel than a QJet, hence it is easier to seal the Holley under boost than a QJet.

Once you get the QJet sealed properly AND are using a pressure bonnet (hat) like the one pictured, the QJet doesn't need additional tuning. But, I always ran them a little rich in order to protect the engine from lean detonation.

That looks GREAT!!, IT WOULD EVEN LOOK BETTER IN MY 1981 TURBO TRANS AM. A matter of fact , I have a 428 short block, a '77 W72 400 4 Speed with trans and a Solid roller cammed 455 with #16 heads. Heck I will even throw in my #48 heads all for that engine.
I know, no deal, wishful thinking on my part. I wish that kit was still available.

Amazing!

Here's a scan of one of the pictures of the complete TurboForce kit for the 1978 H-O Racing catalog. All the parts lightly colored were part of the kit. Also, the pressure bonnet is a polished variant (stock was left as cast and machined) of version 3. There are also additional parts not shown in the previous pictures of the one restored for 78Macho.

I still have that catalog. Craig Hendrickson & Ken Crocie and all the others here. It is a great deal of information that you are offering. I know H-O use to offer a lot of how to articles in the past. I know you don't have the kits any more, but do you have the kit instruction manual available? I wonder if that would be good information for people wanting to build a similar kit. By the way what is Ken's Pure simplicity project.
Happy new year

I don't have a copy of the installation instructions any more, but some of the installation details not apparent in the above picture are shown and discussed on this web page:

Excuse me for asking, you mentioned the turbo covair's vacuum advance unit of the late 60's and also a unit from a Cadillac in the 80's. But you never mentioned the vacuum advance units used in the late 70's turbo V6 buicks. Are these also worth looking for?

[Craig Hendrickson]

Never used the one from a Turbo V6 Buick, so I can't say. Anyone have experience with same?
