Thought I'd pass along a few shots of the intake and fuel rails. Also the blower belt layout is completly redone..

BW

 

Intake...

 

More intake...

 

what is the lower manifold? looking good, i like home-built s**t, when its all said and done you can take more pride in something you did yourself

 

A crossfire lower... also waiting on a vortec truck lower intake.. similar in style.. BW

 

Good idea Bob.. Keep the pics coming!

Cheers,

 

so did you hog out thoes tiny intake ports or what?


looks like its coming along great..

 

Yeah there tiny, but it's just at the port.

Going to see if the vortec intake is feasable before I go grinding the crossfire.

I hope it is since vortec heads are much better than the normal GM stuff and cheaper than hacking a stock set, or going aftermarket.

thanks, Bob

 

Are you going to put the throttle body before the blowers on this setup?

If not i would.

did you see the video i posted of my car... listen closely you can't hear the blower at all until i floor it.

 

WOW! my parents had one of those! the guy used to put our mail in it. just kidding.

ok-ok Im not just PH'ing here, I really like the idea.

wish I could weld aluminum

 

me too. im making my intake version 1.0 out of steel... between the intake and blower, its going to be HEAVY.

but im sure im going to be doing somthing like SATURN5 and swap and change the setup around as i go along.

 

BTW, what the heck lower manifold is that?

 

crossfire....... its the dual TBI manifold that came on the 82-83 cars... the top plate unbolts and you can put anything you want on top...

heres a pic of what it looks like stock (kinda):

 

I was thinking it was but couldnt identify it for sure.

wouldnt those require alot of porting to get a "fullsize" post since they are cast half closed? also the runners inside would have to be cut as well right?

 

Die grinder does wonders... BW

 

Doesnt your belt slip? Does not look like the belt can handle the load.

 

Huh… when you told me about it somehow I thought you were going to use that intake and convert to an M112.

I'm not sure I get it. Is that just a second plenum chamber up top or is it an intercooler or something? It appears that you're laying it out with 2 connections to the crossfire plenum?

How did you get that base so clean???

As a side note, I finally got my TA towed to my garage so I can take it apart and get rid of it. I tried outside but it's too cold and snowing… First thing I did there was pull the crossfire intake so I can modify it for my truck

BTW, a die grinder won't let you do anything to the ports but open up the surface that mates to the head. If you look at the under side of the crossfire casting you'll see that there is no meat to grind into more then about an inch into the port, and if you really wanted to open it up there you'd first have to fill it in from underneath. FWIW, I think that blocking off the bottom side of the port entry on something like an L98 head wouldn't hurt and may actually help.

If you get your hands on an vortec intake do me a favor and get some good pictures of it… I'm still trying to get a good impression of what the deal is with it and if it's got potential for some cool fangling…

 

i can get you pics of a vortec installed on a truck... i'm sure that doesn't help much, cause im guessing you wanna see it with the plastic plenum taken off, but let me know

 

Yea… what it looks like from the outside really won't tell me much… Thanks anyway.

 

A M112 might be possible.. but I would have to start over with the belts.. and new brackets.. etc.

I'm just going to add volume with a larger "upper" plenum, rather than stack up the lid. Thats how the lower came, tho a soda blasting will clean them up nicely.

I'm more conserned with port matching than hoggin the ports, since its boosted, they don't need to be huge.

I'll get you some pics once it gets here. From the few I have seen, it's like a crossfire, with possibly less internal volume. BW

 

Slippage shouldn't be a problem. This is the third config for the belt, with lots of wrap on the blowers, and crank. BW

 

im looking into that now.

*crosses fingers*

my only forseeable problem is how far forward i have to have the blower to clear the stock surp belt.... unless i decide to run it off the stock belt.... but then the pulley on it blower is almost twice as wide as the stock surp belt... id kinda like to take advantage of the wider pulley. so that means i run a diff belt infront of the stocker...

 

Don't bother... the rest of the port is no bigger and you really want the biggest part of the port to be at the start and the smallest to be in the throat right before the valve. The way it is the ledge and inlet angle that is formed when they bolt together acts to form a turbulent pocket that acts similarly to if you filled the bottom of the intake port in the head. I don't know of any of the crossfire guys running faster cutting that area without filling in from behind first so you can blend it properly, but I can think of a couple that have gained a little by filling the bottom of the port in the head and then maching that to the runner.

 

any updates? im curious about the vortec intake

 

Is it running yet?

Jason

 

I think he went with a HSR


-- Joe

 

Yup.... HSR.

The crossfire intake is getting a new lid, a 2bbl TBI unit and is gong into my truck.

 

Don't like my Singleplane setup, Bob?

-- Joe

 

So you drill hole in the single plane intake for the injectors, make fuel rails, and what do you use for the throttle?

Jason

 

Vortec throttle body.

-- Joe

 

Huh? what? Looks fine to me..

 

So the vortec throttle-body bolts up, or do you have to makean adapter plate?

Since you aren't using a carb how do you hold the air cleaner?

Forgive me if the questions are too plebian, as I have never seen the throttle body.

Jason

 

I made an adapter thats 1.25" tall using T6 alum.

I used a "vortec" hat. You can use the stock mounting clips but I was afraid it would leak boost/blow off, so I used metal strapping for now.
