Intake advise
Well, it finally happened. After 8 months of spare time being eaten up ! The engine switch from 6.9 to 7.3 is finally finished. What a difference a few cubic inches make. Of course the Hypermax turbo is a big help over the ATS that the 6.9 came with. I learned a lot during this project. I didn't even have to remove the hood to remove the engine. Just the front bumper and the radiator core support. The truck runs great ! The only issue is the clearance between the Hypermax air filter mount, and the kick down rod for the C-6. Is there a solution to this, or should I just go with an aftermarket air filter system. If so, what are some options keeping in mind that all of the spare change has already been spent on this engine switch.
Any advise would be greatly appreciated,
Peter A.

My Hypermax C6 kickdown linkage didn't work either. After a few hours trying to wrangle a solution, I just gave up and now I just manually downshift going up a mountain.
I put more info about that saga on my article about my hypermax install: Hypermax Van Turbo Install for the 7.3 IDI in a 1988 Ford Clubwagon ? IDI Online
The nice thing about these beasts is, I rarely have to manually downshift. The engine will get you anywhere without many problems. I'd say in the years since I've excluded my kickdown linkage, I only downshifted 6 times, and all of them were above 9000 ft elevation in the American or Canadian Rockies. So it's pretty rare.

Thanks for the reply. I would rather have the transmission function the way that Ford designed it. That is why I thought that an aftermarket type of an air filter might be the answer. I'm not too thrilled with the large carousel type of a filter. It takes up way too much room. Obviously Hypermax designed their mount to adapt to the stock air filter housing. Big mistake, causing the conflict with the kick down rod. There has to be a better way.
Thanks again,
Peter A

If the air filter interferes with your transmission linkage you might consider something like this:

I will have to fabricate a similar air filter setup when I install my 7.3l with a Banks turbo (it's missing the OE air filter setup). There are probably other kits out there at a lower price, or there may even be one for our trucks. I just brought that one up with a quick search.

That is the exact setup that I was thinking about. The only problems are the $349.00 and the fact that the new air filter has about 1/4 the filter area of the stock filter. I just got off of the phone with Ron @ Hypermax. He knew right away what the problem was. Since this turbo setup was a used unit, I had no way of knowing that you need to change the kick down rod to a different rod that is made by Hypermax, and comes in a kit along with the dipstick tube for the C-6 application. He says that he has never sold just the kick down rod by itself, and will get back to me as soon as he can find a price.

Hopefully they can give you a good price on the kickdown rod. You can pick up air filter setups like that at your local parts store too. It might be worth investigating if you can't get the kickdown rod from Hypermax.
