Subpar quality parts? lol

I would definatly say the Accufab peices is nicer then the NW.

And splicing the sensor takes 5 minutes, you reuse your IAC.

Here is a more pics of our elbow...it clears my suncoast ram-air hood
It requires no cutting on the cowl and mounts the TB in the OEM position so you can reuse a standard CAI and throttle cable

Standard Pricing is $300 and will accept any style LT1 TB...52-58-mono-etc






these were temp. mock up pics on my car....I am in the process of cleaning and repainting the engine bay. I will be powdercoating the manifold black....anodizing the elbow black...and laser etching our logo in the top of the elbow.

 

I had the Accufab initially, but wasn't impressed with the amount of side to side play in the bearings, and overall quality. If you compare it to a CNC machined NW 90mm, you'll see why the LS1 guys run it and why cut wires that don't need to be cut? It just makes for one more possible gremlin down the road.

Not trying to belittle anyones setup as I'm sure the Accufab will work, but as far as I know, I'm the only one running a super vic that is actually on a street/strip car and running with NO idle tip in problems, etc. Just sharing what has worked for me.

The real question is...should you do the single plane in the first place??

 

I wonder if the lt1 trans am's have more hood clearance the camaro's stock for stock? It would be nice to fit that elbow under a stock bird hood

 

ray and turbo6, nice setups, turbo6 you have any pics of your car, looks nice

 

This is true especially with the ported lt1 heads not exactly being known for there great flow characteristics. I wonder at what point is there a gain to be had with a single plane? That is also a good question.

 

I think the single plane conversion comes down to do you have heads and cam that allow you to make power past the 6400-6600 RPM's that most LT1 castings will support power up to... If you have even LT1 castings that will make power at .700 lift and your cam is decently sized solid roller and can take advantage of the higher RPM power then you are a candidate for the single plane. The manifold acts as the throat and the heads are the lungs. The LT1 manifold doesn't have enough plenum volume to support large port heads or heads that have been ported thoroughly.... match that with a big cam that can safely make power at 7K+ and you need a single plane manifold...

If you're still messing with hydraulic roller cams, stud mounted rockers, and 6400 rpm shift points then you can probably keep the ltx piece....

 

I still like this if you mill off the water neck and use a nitrous plate.

 

I LIKE!

 

excellent input and dead on.

 

speed density talks about the elbow as playing a key roll in the intake system. How would the wilson elbow compair to rays@ nitrous outlet?

Also what wilson elbow are you guys using?

speed density questions for ya. Back when you had your intakeelbows with holly t body. If you had a mono blade t body at the time instead of a 58mm would you still have made the switch to a wilson elbow and 90mm?

Do you have any pics of that engine showing it from the driver's side? I wanna see what it looks like around the throttle body linkage area. Cobra TB's are slightly wider than LT1's so I'm wondering if they had to notch or grind down that side so the linkage would clear. It's obvious they've cut the original TB mating flange off the elbow because it's shorter than the one in this pic:

 

That is a picture that someone else posted on a different forum I just saved it because i"m considering going that route with a acufab oval TB.

For my car I just fabbed up an elbow to run 58mm TB for now.

 

Here is what I'm running for an intake.







I just bought a wilson elbow so I may not run this one.

Nothing is cleaned up yet but you get the idea. I will take a light face cut off the front of that elbow. I also have to trim the height of the fuel injector bungs and ream the holes to size.

 

Is the super vic a 4150 flange?

Because that elbow you were looking at is a dominator flange.

Tony.

 

Well if your right I will have to resale it. If the part number he gave is right then it is a 4150 flange turned sideways. If that is what it is I'm going to turn it and redrill the flange.

This is a brodix hvh intake with a 4150 flange.

 

This is all very interesting. I’m planning a short block during the winter. I would consider an upgrade from my stock manifold but the only LT1 manifold on the market is from Edelbrock and it offers no significant improvement. It’s just not worth the money for the few horsepower it may make. Being that any SBC manifold will bolt on the LT1, how do you guys think these manifolds will do?

There are a few "Ram Air" type manifolds out there similar to this:



Or, Wilson has a two piece composite modular manifold, they claim some pretty good numbers, I have no reason to dis-believe them, they have a very good reputation:

 

I was under the impression that dominators are ment to be turned in any direction. The 4150's are either front or backwards.

I could be wrong though.

When I ordered my wilson elbow they sent me a dominator flanged one by mistake.

Tony.

 

Keep this alive

 

I will let you know in a couple days when i get it. But I think this is an older one that was not machined around the outside like most 4150 flanges.
