looks like a much cheaper alternative for you and may even work better on the street than the mini. Seems it would be easier to work with.

 

Don't forget you have to buy a 4bbl type TB or the flow killing elbow. I really want to convert a dual plane to EFI, but it's going to be hard to get it all under the hood. EGR and other plumbing will be fun too. The single plane will have much better distribution than the miniram, superram, or even TPI. Someone on corvetteforum picked up 2 tenths and 3 mph switching from the miniram to an efi single plane.

I prefer dualplanes myself, but you have a major headache on your hands mounting fuel injectors and rails. Dualplane runner ports are not anywhere near level. One solution to that is to cut threads on the injectors themselves so they screw in, then run separate plumbing to each one... what a mess.

A much better solution can be had if you contact Keith Wilson (Wilson manifolds 305-771-6216 ..Florida). They can rework a single plane to have more performance than either an out-of-the-box dualplane or singleplane... the best of both worlds with absolutely perfect distribution. This company has had several of its intakes banned from Winston-Cup for making too much power. They come highly recommended by R&D wizards Roger Helgesen & David Vizard (reference Vizards newest book).

You can actually use about anything for a throttle body... even an old carburetor if you remove the boosters & seal the holes (plus add a TPS).
The elbow is not all that bad though. It can easily be chopped in half for porting, or extrude honed to widen the bend area.
Let us know what you decide to do and how it turns out. I would be curious.

I'm contemplating this swap for myself when I go to forced induction... some day.

For the TB, I was tossing around the Idea of using a mono blade TB. A right angle setup could be cheaply fabricated from muffler tubing and some thick plates for the gasket surfaces. Maybe even a boxed type upper with the forward facing TB. Any comments on this? Distribution problems? I've also got the holley 700 cfm 4bbl that I'm using now that I could use as an air meter.

I found Wilson Manifolds on the net:

"cheaply fabricated from muffler tubing and some thick plates for the gasket surfaces. Maybe even a boxed type upper with the forward facing TB. "


should be no problems.
The cross-section at the bend needs to be much wider than each end for good flow.

 

jegs, and lingenfelter, sell a adapter plate to mount a tpi style throttle body to a 4 bbl intake manifold, if i can find a link ill post it.

That is the adapter. Accel makes it

 

Aaron,

Do you have the name of the person on corvetteforum that switched from the miniram to a single plane or a link to any messages about it? I would like to hear more about that deal. Thanks.

Has anyone done this? I believe the Q-jet TPS runs the same voltage range & @ 750cfm would flow enough for most sbc projects. Hmm, no more Q-jet choke annoyances. Interesting concept

 

As far as I know, this is the first time this has been mentioned, and it seems to me that this should interest people a lot more than it has. One of the big problems I have with TPI is the cost versus a Carb. A tpi upgrade to higher flow and more fuel would cost enough to get you 4 or 5 carb and manifold sets, and they would be more or less equal, this being from a cost perspective, no Carb vs TPI please. And this seems like a way to really cut that cost down, and have a better setup. This also means that people wouldn't have to buy from those guys at TPIS to get a decent short runner setup. TPIS seriously sucks. They should be locked up for fraud, and for being such a bunch of d*cks.

Would this work with the parts mentioned? Assuming the accel made 'L' is used (anyone got a price on that?), would all of the cables reach? Does the throttle body reach the stock intake setup, or would an extension have to be fabricated? (for us MAF guys...)

Anyone tried/looked into this?

 

I'm not sure about using the carb as the TB, I mean what about the IAC valve? But, in another effort to reduce costs, what about using a 2bbl-to4bbl adapter. Mount your stock TB (for those of us with TPI already) onto the 2bbl side, and bolt the adapter onto the manifold. You would be able to use all of the stock linkage, but would have to fabricate the air cleaner somehow. What do you think.

Someone on the TBI board was saying you could buy a stripped holley TBI unit for cheap. They have these units in 650, 700 and 900 cfm @ 1.5". Holley flows these with fuel so your actual flow w/o injectors would be greatly increased. Your stock TPS would probably work, maybe even the IAC (not sure which style TPI uses).

 

$303.00 for the elbow, fuel rail stock and the injector bungs that would have to be welded into an exsisting intake manifold.

$250 for the elbow itself....

I'll let you guys know in a few weeks what the setup does..

Can't wait to hear how these work! I'm glad these alternatives are finally gaining some popularity. Theoretically, isn't that 90 degree elbow going to kill flow? Only problem with the vertical TB is finding space for ducting under the hood (Vette).

 

If hood clearance is a major issue, you might consider a low rise single plane for the swap. The Weiand Street ram # 7525 is only about 10-15 cfm behind the Victor JR in flow.

 

Okay guys.... I just ordered the Weiand intake and fuel rails, and the Lignefelter elbow, plus a brand new spankin BBK throttle body....

Parts are suppose to be here within the next week or two... I'll let everyone know how it goes......

Talked to the local speed shop guy in length today (and ordered my new heads) about converting the intake. He says that many people epoxy in the bungs and that the drilling can actually be done with a hand drill. He says just mark the intake with a strait edge to get them all in line, measure the center lines of the holes in the injector rails and mark the center lines on the intake. Drill the holes a little bit large, assemble the injectors, rails and bungs and epoxy the bungs in place.

 

Okay guys...

Can we say this elbow does not look very gas friendly????



If someone can e-mail and tell me how to post a picture, I'll post them a little bit later today... I'll even post pics with the 58MM BBK throttle body....

"If someone can e-mail and tell me how to post a picture..."

Could someone please email him w/ directions?

 

I was reading this post and saw someone mention the use of a dual plane intake.
I dont know if this would work but it might be worth checking into.
I remember seeing a new Edelbrock Performer RPM AirGap intake and it had bosses cast in the runners to drill out for a direct port nitrous system, could you drill out the cast nitrous bosses on the runners and install injectors and a fuel rail and use the dual plane intake?
Just a thought for another setup.

 

I've also thought of the idea of using a regular manifold, with the fuel injector adaptors. Look at Holley's single plane manifold # 7525.
http://www.holley.com/HiOctn/ProdLin...AMSM/7525.html
This would allow the use of an EGR. Does anyone else know of an idea that would retain all of this emissions crap?
