Does anyone here have an edelbrock intake?

Post #1 by clintonvillian » Fri Dec 07, 2012 8:56 pm

I would like some dimensions off of it to model a sheet metal intake off of....

I am going to do a DXF drawing of it, so it can be laser cut. Some of you could benefit from it as well.

I would be interested to see what you come up with. I was thinking about making an intake but would like a proven design before committing a bunch of time to it.

Thanks, that is what I was looking for. I don't know how I missed it.

Only question I have is how will rectangular runners with perfect 90 degree corners in the compare with a casting with filleted corners. Any thoughts on what It would do to airflow....Or if it would matter.

:hmmm: Airflow is affected by the length, port size (there dose not seem to be much difference in flow between a round or rectangle port of the same size), and is also affected the number of and sharpness of the bends. So yes a perfect 90 degree (short bend) corner will flow less than a gradual (longer bend) 90 degree. To know how much though you would need to do the math or set it up on a flow bench. The sheet metal intakes have been out performing cast intakes for many years in drag racing (since the 1970's) but would it mater on a 1V intake for street and economy use? My guess is that it probably would not, even so if you kept the port sizes down some from the stock size and made the bends free flowing might be a fun project to try out. If you look at those pictures of the Edelbrock 1V intake as compared to the two stock intakes before it, the Edelbrock has the longer gradual type of bends. Over the years I missed out on getting one of the Edel's SP2P a couple different times, the design looks very good to me for a stock or very mild street truck but that's just my opine. :nod:

I didn't mean a 90 in the runner, but in the crossection of the runner........If that makes sense. Like where the ports of the head have filleted corners....the castings have filleted corners you can see them when looking at the edge that mates to the ports on the head.

Looking from the top mine will mimmick the edelbrock, EXCEPT I am designing mine for a four barrel intake.......for future options. Its is easy to adapt it down..not up. Plus I plan to run a holley 390 or throttle body efi........maybe.

:hmmm: OK I got you. In that case yes a radius in the port corners would be much better flowing than a square 90 corner. Flow would be more turbulent next to a straight butted corner but it may still work. On the heads intake ports flow is the best (or fastest) at the top of the port and the port floor is the slowest. Since you are going to a 4V design take a look at the top Holman Moody intake too maybe a cross between the two designs. Round tubing might be easier to work with also. Or if you don't mind a lot of welding slice the tubing to use for the corners. Good luck on the intake project its an interesting idea :nod:

The intake ports are roughly 1-3/8" x 1-5/8"
Assuming you're doing some port work, consider using 1-1/4" Sch 10 SS pipe to fab the manifold. At 1.66 OD x.109 wall it has an ID of 1.44 and it's thin enough that you can heat and form the ends of it into a shape to match the ports while leaving the majority of the x-section round for optimum flow. As an added plus you can get 45° and 90° ells already made, just add TIG. If you can't get Sch 10, Sch 40 is readily available everywhere but its .140 wall going to give smaller runners than you might like and would be a bit harder to hot work

Another possibility would be round mechanical tubing. 1-3/4 OD x 12 ga. has an ID of 1.53, almost perfect but there are no pre-made elbows, you'd be bending your own sections. If you're doing significant porting on the head, 1-3/4 x 16 ga. has an ID of 1.62" and would be much easier to work :hmmm:

I had originally thought about using square tube, but now thinking maybe round 1 3/4 exhaust tube might be easier.
Pre-made bends are readily available. I was also thinking about setting it up for 2 2 barrel carbs equal distance apart.

Are intake manifold flanges available anywhere? Maybe someone has a pattern?

Yeah search ebay....... a couple gues make them on there. I am going to design my own so I have the design available. Most of the thickness's sold from the guy on ebay doesn't match my header flange thickness of 5/16".

I'll post pics of my plans on here when I get them. I will be doing mine like FTF did his aluminum intake, I just think welding the square corners is easier and less HAND fab work than getting all the tubing to fit. Just my preference.

Not really related to the original question, but still interesting to look at as far as manifold design goes. A while back people were playing with the stock EFI intake manifolds (uppes and lowers) to make custom carburator intake systems..
EFI CARB frankenstien (2 pages, be sure to look at both)

I am still waiting for somebody to make a single large chamber design with a front mounted throttle body to be used for turbo applications...

Do you all think that edelbrock intake would work with a boosted system?? Assume it had a 4 barrel opening on it though...

For a blow-through, you don't really need a 4V carb.
The Eddy would work as would any other manifold. It all depends on how much air you're trying to stuff through it.

Well I want to run 6-10 psi. I just want something that if the super charger becomes to much of a hastle I can unbolt the stuff and just run a stand alone carb and still have a peppy motor.

A blow thru set up with a remote mounted supercharger would be easier to do that on. I'm laying out my set up so I can just pull the belt off the supercharger, cap off the outlet of the intercooler, swap carbs and throw on some air cleaners and re-time it to go back to a NA set up. On my truck I'm doing so I can run E85 spring thru fall and swap back to 87 octane NA for the winter. Or if I ever have an issue getting E85.

Tuning the carb on a blow through setup worries me some. Of course I will have a AFR sensor. Is there any difference tuning a blow through vs draw through?

I thought there was a big difference in jetting. Something to do with the density of the air and that it is being pushed rather than sucked...

A draw thru set up requires a much larger carb then a blow thru set up does.

There are some modifications that need to be done on a blow thru set up. Here is a website with a lot of good info on it.
