Hey guys I just brought RamAir's single plane conversion intake and I need to know which elbow is the best to use with the 58mm tb I have, I'm leaning toward the Nitrous outlet elbow but I wanted to get opinions from guys who have single plane intake conversions. Also can you guys post pics of your setups, thanks.

Not sure if this will help, but I remember a thread titled Intake ****, or something like that which had several pics of Single Plane conversions in it.

Nitrous outlet 860 elbow will have the most clearance without any crazy bends or negative performance, so it will be a great choice if you have a tall intake like a supervic and dont want to massacre your cowl.


If you can find a more traditional elbow like the intakeelbows.com elbows they will outflow it, but with a tall single plane you will need an aftermarket hood and/or trim the cowl.


Stay away from "low profile" garbage intakes like Edlebrock makes...some manage to even leave the throttle body UNDER the intake flange .


Ideally you would run a 4bbl TB with a carb hat, but that takes a lot more work to make work and is more expensive. I may do a back-to-back test comparing an intakeelbows.com elbow w/ AS&M 58mm to a 4bbl TB/hat setup, but that will be a long time from now since the new motor isn't even in the car yet...


Note that any gains from a 4bbl setup won't be from more air - in fact, most flow less then an LTx style dual 58mm. Any benefit would be from the straight shot of air and not running an elbow.

I was originally planning on going with the Nitrous Works elbow, FWIW.

Thanks guys, hey puck why do you say the 4 hole tb is harder to setup and make work?

throttle cable, return springs, cowl clearance just to name a few.

I am interested in that conversion. What kind of gains could one expect from it? Price and where can you get it?

Wicked94Z

iTrader: (26)

questionable gains below 7k rpm. price ~2k if you do it right.

Like I said earlier, most actually flow LESS then a quality dual 58mm LTX TB...but in certain situations you may benefit from the straighter shot of air.

I haven't seen enough back to back testing to see how much hp and how many RPMs you need to spin for it to be worth it, but for most people I would say its a waste of money.

FFB recently did the conversion but doesn't have much hard data yet...

i was speaking about single planes in general. I've been talking to a local super stocker who's been doing LT1s for the last 15 years. He says he has yet to see a single plane produce anything but marginally improved track times over a properly done LTx manifold. If we had the hood/cowl clearance to get some plenum volume (spacers) then they would show better gains. I believe Joe Overton said he once stacked 6" worth of spacers and the car kept picking up. I think a 4500 manifold with cloverleaf and plenum mods would be the ticket, but then you're stuck paying for an EFI conversion + 600 bucks in porting.

Well besides porting for a 58mm TB and gasket matching the factory intake, what else could be done to improve it?

just curious the vic jr would be good for FI setup right????..but not so beneficial for a non carb n/a build???

Wicked94Z

iTrader: (26)

no reason not to do a super vic, It will kill a vic jr everywhere.

cutting the top off of it and hitting the whole plenum. See fek77's intake that I believe bret bauer did. Might take some digging, but look at what steve quinn did years back.

i run a victor E with a wilson manifolds elbow and a 105mm monoblade and it fits under my stock cowel just not the stock hood lol

got a pic of it showing the clearance? I've only got a 2" cowl on my ****

I brought the Nitrous Outlet 860 elbow and it's great, now I need to find out how all of you guys with single plane conversions setup your vacuum ports and map sensors with the single plane setup?
My thought was to get a vacuum block like the turbo guys use but I still need a way to hook up the map.

Puck

Just mount the MAP on the firewall or something with a short piece of tubing leading to a nipple on the elbow.

If you want it closer you could probably make a super simple bracket coming off of a fuel rail bolt.

I've got some nice clear pic's of the double welded 860 Elbow that i sold a while back(Pictured in my first post). It is 4" high from flange to top and leaves the TB fairly close to its stock location. Great for people who want a simpler switch to a single plane.

Has anyone done a single plane/LS style throttle body? That was my plan, but I haven't seen it done. I was planning on getting the 24x kit and using the LSx throttle body and the vic e intake. I'd also probably use an LS style MAF but I haven't really looked into everything yet, I'm completely redoing my suspension this winter and am planning on building a new motor next summer and installing it next winter if my job situation goes to plan

Otherwise the 860 + vic E + 58mm TB would be my second choice.
