Wondering if anybody around SoCal would let me check out their engine for a bit, just to poke around the supercharger set up...

Specifically interested in the 32v/S4+ "Andy Keel" aka "pizza box" types.

Trying to jam an Eaton onto my 944, am cramped for space with a DOHC head, and think something along those lines could work for me too. Internet pictures abound (feel free to post up here too) but would like to actually get eyes on such a thing to answer questions in my mind.

Why don't you look at old Huntley racing setups on Google images?

An SC from a Thunderbird SC is not big enough? They don't use a manifold and can be bolted to the side of the block.

I have a brand new old stock 1.7L Autorotor supercharger that would be better for that application.

Thunderbird supercharger is sufficient flow for both the 8v and 16v head of a 944. There are people that have done this on the 944 forum.

I am well aware of the Huntley setups...I know the guy who designed the thing originally. But the purpose of this thread was to actually see the 928 manifold in person as you can't get too much detail from photos alone - not even reading through the twin-screw thread answers all the questions. Specifically the injector placement/arrangement...

I am using the Thunderbird SC Eaton M90.
I have the mounting built already, and have a manifold for a SOHC engine, but I have decided to try a DOHC arrangement...



Price of the blower is a major factor - while an Autorotor would be nice, this whole project isn't worth all that much to me, more an experiment in curiosity, not enough to justify spending Autorotor money (unless you're looking for $400 or less).

I've been planning on this since before you dropped off sunroof latches at my house in your old 944...I know all about past 944-SC efforts and am trying to do my own...I am only aware of 2 DOHC 944 that have been Eaton-supercharged and both of those used the Huntley kit.

But what makes mine a little more different is that I'm using a DOHC 928 head... Which makes the Pizza-box intakes much more relevant as a "template".

You do realize the motor sits at a different angle and has 4 less cylinders? It doesn't matter what the pizza box looks like. All you need to do is design a basic shaped 'box' type manifold that has the ports and the proper holes for the breathers in addition to your intake pipe. DarrenD did the same setup and it worked no problem, save for a 2v head. The same setup can be adapted to the 4v head you are using. Just figure out your EFI or you will blow it up just like every other SC'd 944 out there.

There are plenty of renderings in the twinscrew thread..... but here you go:

For the record, I have this manifold you talk about already designed for a 944. But it's somewhere in a binder inside a box, in a storage, sitting right next to my ITB project.

I also opted not to do it because pouring all that money in a 944 would be less practical. If you want power still, just look at a TPC LSx swap. Don't torment your mind.

Hi Spencer,

I am up in the Bay Area but I have this old Eaton set up on my car. If the drawings Hans posted don't get you what you are looking for, I'd be happy to take some measurement or pics.

V2Rocket

the idea is to look at the Pizza box for some details and then make "half of one" to fit...

I have VEMS so full tuning capability and a 951 bottom end...don't worry about anything blowing up.

Saw those, thanks. They do answer some questions in my mind.

Stopping "pouring all that money into a 944" should have happened 10 years ago...I don't care about the amount of money going into the car. The car has been crashed and repaired and is essentially worthless for resale so it is an "anything goes" toy at this point...I thought about the LS stuff but I've not yet seen a single V8-swapped 944/968 in person that was "finished", they all had bugs or niggles or something missing to make them not quite nice. Fast, but incomplete...besides, way too much BS hurdles to jump for CA registration, whereas the SC I can just unbolt every 2 years for smog...

This SC project was born in 2007 but I have not been able to do anything real with it until very recently due to a lack of money from 2007-2013 and from 2013-present, lack of time...but that is all changing now, and I can finally f***in' do it...lol

It has always been the goal, no matter what else has come along the way...

I may contact you later for some photos, thank you.

Spencer, LS Swap and BAR Smog Ref. Done.

VT951 had a finished car. Simple fact for the LS issue is you MUST use an LS-based engine from a car, not a truck like a Silverado. That is where the price goes up fast for an LS1 as people have caught on to the swaps. Don't forget the 944 swaps done do not use the factory PCM (ECU from GM). These aftermarket tunes are the issue. Start with a base PCM for a C5 Corvette LS1, and then as you add mods, make the appropriate tunes. Some of these guys out there just throw a cam in and expect to gain tons of power without tuning the ECU. Look at LS1Tech if you want to learn more.

On a side note, I have never seen a 944 with bugs or 'niggles' either, especially on Rennlist or Pelican


In the end it's your money and I ain't your papa.

VT951 is in Ohio...apples to guacamole

The main problem with BAR'ing an LS'd 944 is the exhaust manifold on the driver side, there aren't any "stock" or "Carb EO-legal" headers that clear the 944 steering shaft (that I am aware of).

And even if there were, I still wouldn't do it...I've driven several, including Odurandina's LS7 968.
It's not for me.

Mongo

That car is a marvel in it's own. OD put a lot of time into it. While I haven't driven it, I have seen his ingenuity in pictures. Very impressive car. That LS7 would do wonders in a 928 with a T56 and 3.42s.

I also recall seeing a header with the EGR stuff on the passenger side, away from the steering shaft.

But why would you be worried about CARB with an LS engine when what you are doing forced induction wise would **** off every environmentalist at CARB???

V2Rocket

Pictures are one thing...you should see it in person.
It is incredibly fast. But as an overall package/car...it needs work. The nicest way I can describe it is "halfway done".

Because I still have to pass a smog test every 2 years no matter what is under the hood, and like I said...the SC stuff unbolts very quickly and the car goes 'back to stock' in a jiffy...Whereas it's harder to swap your V8 back for a 4-banger when needed
