well guys, i'm back.

since body work jsut isn't holding my attention, and i have Leo's book at hand, forced induction came up alot in my mind.

and why shouldn't it? a relatively stock engine, making fairly impressive numbers, with a bit of accesorizing.

so, a few Q's about this whole business.

1.) can multi carbs be run with forced induction?

2.) can a turbo be used with normal long tube style headers?

3.) turbo vs. blower?

4.) any donor vehicles to look for "accessories" on?

5.) am i out of my mind?

in the past week i've considered both turbos, and blowers, and even squirrel cages as can be seen from an earlier post. lol.

so, set me straight. not to take the easy way out, but, what can i do to my 292 to make her scream?

.later days.

If you want to keep it simple I'd say supercharger.

Forced induction cost big money unless you can scrounge up all used parts and fabricate everything yourself. Even so, a turbo would probably be cheaper. Slants have been running for years now using junk yard turbo setups put together by their owners.

Theres a discussion on supercharging the Mopar 6 going on now on another board. A company will soon offer a supercharger kit for around $3400. You supply the 4 bbl carb modified for blow thru($450), the fuel injection fuel pump and boost bypass regulator($305), and recommended water injection($740). Your motor should already be up to the task for the increased power or add some pocket change to the above figures.

Heres the mock up of the system:

If you already have headers, no use throwing those out.
I seen a B&M blower 144ci in a 66 Nova.. owners name was Mel .
He had used a Offenhouser or Cliffold 4 bbl intake manifold & made an adapter to fit the 144 blower to the 4 bbl manifold. Really clean setup.
It was in a magazine can't remember which one ,I have the issue somewhere. I will look for it.
That way you do not need a super special carb.Or a special fuel regulator w/a boost sense line hooked up & so-on.
It ran Low 12's street driver 5 speed T-5 I believe. I talked to him years ago here in Ca.
Nice guy.Maybe some of you guys out here remember it? It was a Red 66 Nova & was in I think a Car Craft street challenge deal. Against a 55 Chevy two late 80's to 90's mustangs, & a GTO? I have a Paxton supercharger on my inline. I am going to switch to a turbo set-up though. I believe there is a lot more fabrication to install a turbo set-up correctly,(for best horsepower:-) )(just my 2 cents)
I suppose it is easy to get a junkyard turbo & attach it to a stock exhaust manifold w/a simple pipe bent off to the side. I think Innovative turbo( it's not shown on there website... you need to call them to find out or email them.) makes an exhaust cast iron manifold for a 194-292 engine that hooks up to a T-3 flange. I forgot who it was on this forum that bought one & posted pictures.I think it was about six hundred dollars. Should be able to look in the archieves?
Any more questions just ask on this forum so we can all learn...& of course BS
Love this talk about blowers & turbo's :-)

Pic of the turbo manifold available from Innovative.
This is the guy who bought one??

There is a picture of the manifold on that posting on 2-16-05. Just can't seem to repost the pic. Can anyone else do that?
Type in tubo manifold (search for) & it will be there.

I believe Larrowe in Oregon sells a blower manifold for the 194-292 motors.

wow, so quite a few options out there. thanks for all the replies guys.

does anyone know of a way to have blow thru multi carbs? well, i guess darw thru would work. just some fabrication of mounting and junk. etc. ya know.

also, would there be a good scavage vehicle to look for a blower off of? nothing too radical of course, like a 6-71 GMC...heh, its for the street!

also, the magnetic connection switch..good idea? for running normal, but then when you want the extra, flip the switch, right? or am i just totally misled in my assumptions?

granted. this stuff is WAY in the future. but, its always nice to dream. besides, who can't beat 6 in a row, multi carbs, true 50's duals, AND a blower, for style? hah.

.later days.

Sam,

I suggest that you get a book written by Corky Bell "maximum boost" and read it from cover to cover - it will answer a lot of your questions.

I am in the process of build a turbo 292 motor that will be EFI port injected. If you check in this forum you can find a link to the turbo intake and exhaust flanges. Since I have a lot of work to do on the basic truck the turbo will be added later after the truck is on the road.

I have an extra maximum boost book if anyone is interested in buying it? It is use but is in great shape. Cover has a little overspray on it.
I think they are $35.00 new?

Hey all,

I've been lurking a long time, but topics like this bring me out sometimes.

The center of my effort is an intake manifold that I'm building. I'm an engineering student (3rd year) so I've got a few 3D design tools at my disposal. And a spare head. And an injection setup off a v6. Also I have access to milling machines and through a co-op, some time on a CNC mill. And you add it all together and you get this.







Yes, those are 4 injectors per port.

I had always figured on 2 injectors per port so I'd have more flexibility in chosing injectors and controlling them. But for the effort required to convert to EFI and build a custom setup, why stop there? The two injector on the steepest angle (rear injectors) are to be for the lowest, cheapest octane I can buy. They'll run 98% of the time and do most of the work. The secondary injectors (at only 20 degrees or so) are for race fuel. Probaly 100 octane anyways, possibly much more. I've build a Megasquirt controller and I understand it will be more than capable of running both injector setups. The primary fuel system I haven't quite figured yet, whether I'll go surge tank or in tank pump. The secondary will probably involve a small fuel cell.

I've got a long range goal of adding a turbo to this engine and I think the practical availability of high octane fuel will make it very easy and very safe to apply quite a bit of boost to this engine. I intend to boost this thing like there's no tomorrow. And if I break it, or it doesn't work as well as I hope, well that's always a chance. I'll have tried something different.

A few notes. This isn't quite my lastest version so a few things are off. I haven't decided how to do the rest of the intake. Probably one throttle body at the front mounted horizontally so I could feed into it from an intercooler. Also the fuel rail is huge in that pic, a size larger than I intend to make it. I can't recall the -an size, but that pic has it too large.

As of right now I am focusing on thos 3 blocks that mount the injectors. I programmed and CNCed the inside profiles with a ball end cutter (kudos to a member for that suggestion). That's done. I've machined 1 block for injectors, but that's all. I wanted time to look over the 4 injectors idea. Now I'm hoping to get machining the rest of them in the next month.

And no, I won't promise anything soon because I actually started on this over a year ago. And I'm probably going to take that much more time.

Any comments you guys have would be really appreciated. I got a lot of ideas from this board.

Whomever Cosmo is. I got your email about the book .
I tried to email you back a few times...but cannot go through for some reason?
