Sweeeet!

What was the question?

Moving to the lounge where it will be appreciated since you dont have a question.

 

Yes indeed, that was a BIG trigger pull $$$$$$$$$$$$$$$$$$$$$$$, love the EFI staggered stack Hilborn set up also but again moooocho $$$.

 

That looks like a really sweet setup. What fuel management system are you using?

You know it would be nice if they gave a guy an idea of what their systems cost and the prices on the different options. It must mean that it is most likely out of the price range of most people so why even bother?

I've been looking into spending some money on a fi system myself. Possibly not this one but being able to see a price would be nice.

 

Sweet deal but if you need to ask how much you can't afford it..

Really? That's a good one. :drunk:

 

If I had that set-up I would have to pull the hood off the car (my 36) to show it off. I'd have to shine everything up. I'd have to keep it clean. I think I hate this set-up...:mwink:

That is gorgeous!

 

Ya just gota love the look of those stacks. I couldn't afford a factory built one even if there was one made for my Northstar engine, but I wanted one bad enough to build my own, and it turned out to be the most rewarding project I've ever done, as it runs just friggin' awesome. nothing like hearing those ITBs singing their unique song as the revs near redline. :thumbup:
I actually had curved tubes with an air filter system on mine until (literally) about an hour ago, as I just finished fabricating and installing a straight stack setup with stainless domed screens in the tops. the look is worth it to me, and paper air filters are for wussies anyway.

 

Custom built Northstar stacks, this thread just gets better and better. I love custom fabbed parts...the screens are a nice touch and they look great straight.:thumbup:

 

Yea Northstar very nice fab work, good looking engine. My neighbor had a custom built Northstar in his Sand rail, he had lots of bucks so money was no problem. I never saw it in the sand but heard it run in his shop, for a relatively small engine it sounded very healthy.

Regarding the cost of these EFI units, I got a wild hair when I started building my 507" Cadillac. I ended up calling Inglese (sp?) and asked them about my setup. The guy said yes we can do it but you're looking at developement costs since we've never done a Cad, custom intake and the electronics....then the F.I. setup. I vaguely remember waking up on the floor after he told "around $12-15k".

 

I had one big advantage in that I started with an EFI engine. When you really break it down, all I did was split the throttle body from having one very large hole into 8 smaller holes. . even though they are now in different locations, all the sensors and the ecm don't really know the difference either.

If you wanted to build an ITB setup for your Cad, for example, you'd need to find a suitable late model EFI system to base your "8 stack" system on first. I'd conceder a Chevy TPI system just because it's simple, and uses a (ecm controlled) distributor. I'm betting you could swap the guts out of your Cad distributor for the TPI HEI module fairly easily. The intake manifold would likely be the hardest part, as I doubt there's a Weber style manifold built for that engine to work from, so you'd be hacking up an aluminum carb manifold and welding on new runners. For an ECM, I'd highly recoment the Holley HP, as you can tell it you have a hopped up TPI motor, set the fuel/air ratio you want to see, and pretty much just let it do the tuning for you from there.

The main point I'm making is that most of these projects never happen simply because somebody pulls us down to their level by telling us it can't be done, and we believe them.

FIGHT GRAVITY,

 

What do you expect for a delivery timeframe? what ECM is provided or recommended?

 

Thanks for your input guys,
The manifold should be complete in 4-5 weeks then I'll fit it to the block
then ship it off to eightstack for assembly 2-3 weeks.
I'll probably run Accel ECU as that's what the local tuner recommends.

Yes it was pricy but I don't plan on selling the roadster it's been in ours since the early 80's and will probably be the last to go someday.

I'll be into the system around $8000.00 but I'm bartering some machine shop time so that made my decision a little less painful.

This all happened a couple of years ago, had to punt and go carb'd, still not a bad deal.

 

A couple of years ago, I saw an Australian version of an 8 stack system on a LEXUS 1UZFE engine (Lexus LS400 V8) and I got really turned on by it.

That's when I decided that when I (finally) redo my Model A coupe (I sorta kinda wounded the SBC that's in there now) it will get a 1UZFE and an 8-stack as well.

 

Guys, all the work thats in here is absolutely gorgeous. Thank you for sharing

 

System is done, updated pictures

 

VERY nice. they sure did a good job of hiding the electronics and injectors etc.

That's gorgeous! I really like the black.

 

It looks nice, but doesn't really look to me like converted stack injection...looks more like Weber or Inglese Carbs converted to hide injection nozzles and wiring??

When I think of "converted Stack Injection", I think of Hilborn, Crower, Kinsler, Pete Jackson, Algon true individual body tall stack injection manifolds converted to EFI.

Quite a bit of difference in looks, IMO.

Your set-up looks sharp though, would be awesome on a Cobra replica or on a street rod, but wouldn't fit the vibe of a "Gasser" type injection build.

Have to agree with you the thread title is for the company that makes them.

Absolutely stunning, and you can see the workmanship in not only the casting, but assembly and detailing-very, very nice-this is going to be gorgeous when it is installed-

 

We do a lot of casting design; and my boss was VERY impressed with the quality here. Thanks so much for following up. What a gorgeous system!

 

Automotive jewelry that is very functional, looks amazing and is beautiful!

 

New pictures,

 

It is very sharp looking, I really like the old school girdle valvecovers, haven't seen a set of those in 25 years. New production? or NOS?? or a swap meet score??

Those stacks need about 8" of extension on them, don't cha think ?! :evil: Just enough to sneak the belled ends and screens up through the hood skin :thumbup:

 

NOS on the Valve Covers had them stripped and powder coated
Going stelth on the stacks.
Although they would look great thru the hood top.
Thanks for the compliments.

 

i wouldn't bother with that hood or at least the sides
your going to be asked to open the hood at every stop

it does look good

 

. I wouldn't think motorcycle throttles would be big enough... a Caddy 500 has as many cubes in one cylinder as most motorcycles have in 2,3,4, or 6 cylinders...

 

Don't make the mistake of comparing throttle body size to carb size. it's a whole different ballgame. here's a really good site to gain some insight into what's actually needed and why.

My Northstar is ~289 CI and is comfortable running up around 6500 rpm, so the Gixer TBs worked out just right for my application. you're right that the bikes have less cubes per cylinder, but they commonly turn up way more rpms than a V-8 also, so it works out.

. For an 8 tube EFI system, I would want the throttle bore cross sectional area slightly bigger than the port cross sectional area... prolly about 50 MM diameter...

 

what you want and whats been proven to work best may not always coincide.
