Question Edelbrock Single Plane...

Question...? I have this intake and 90 degree elbow for my next project. Looking at the runners and comparing the plenum "volume" of the intake compared to my FAST, it just looks awfully SMALL. Does that really matter?

We have, it seems, all this volume and short runners in the FAST intake, or any LSX for that matter, but very little volume in the plenum and longer runners in the Edelbrock...I'm not a guru when it comes to VE of intakes so I need help in someone explaining the benifits of either for our FI applications or am I over thinking this as I usually do.

So, question is which intake does everyone feel is a better performing intake for a FI application? Even Edelbrocks web site says the intakes are good for 600HP...well, thats just not enough.

Whats everyone's opinion or should I just get a custom one built...but by whom?

From what ive seen/heard its the way to go for a "big boy" setup where your turning higher rpm, have alot of cubes and shooting for big big numbers. For reference all the big hp guys seem to be using the single plane i.e. ohioboys,harlen, and some soon to be big hp guys kyle (nastyta). i say if its for the car in your sig which it probably is then i say deffinately keep the single plane.

A lot more.

Question is, when does it become a real benefit over an LSx style intake ?
And what, if any losses are seen at lower rpm's.

Yep, I knew that number was N/A...but just curious how much would be too much for that type of intake if there is such as thing as "too much". Or does everyone think the air induction qualities are just fine for our FI application?

It does have some pretty small runners compared to my FAST. I realize some port work can be done but would all that work really be that beneficial for our FI set ups? N/A yes I can see that being a slight improvement but not FI. Am I wrong here?

Not that plenum volume is significant (in my opinion), remember to take the intake elbow's volume (for total plenum volume) into account also.....

I agree with Dynedta, single plane all the way.....

Aaron, your right...I didn't think about the elbow's volume...

Thanks for helpin' me out this morning. I really like those valve covers your doing also! Very nice work...

I'm going to be running Aaron's elbow with an Edelbrock intake, just waiting on some parts. I got Aaron's elbow, it's worth the price for sure.

If you measured the pressure in each runner under boost you'll notice a difference between the back cylinders and the front.You normally have to tune a car off the lean cylinder's which are ussually the rear ones when ussing a LS6/FAST intake.Ussing a Carb intake can even out the cylinders which could result in a better tune/more volume and a more even running engine under boost.

I have a few Carb intakes going on Turbo cars,so I should have some info soon. Also I use the 90's from intakeelbows. I'm hoping the bend's are not too tight,but if I have to we will wled in a diverter plate into the elbow.They fit under the hoods without lowering the engine which is good for the street cars

Thanks, that was my 1st understanding of the Edelbrock intake which made me purchase it along with Aarons 90 degree elbow awhile back. A better, more evenly distributed air/fuel mixture over the LSx style. Guess I was just over thinking things as usual. I want to have the best combination available for what I'm doing...

Another option perhaps ??

Has anyone considered going down this route ??

4 barrel TB ( not using their 4 x injector holes though )


And an inlet to the intake/4bbl like this procharger item ?

I looked at those, but the cost maybe more than the elbow I saw they were close in price, but they haven't taken into account the cost of the blower hat.

I was thinking they might offer better throttle response for a road driven car ( non automatic ).

No idea if it would flow as much air though.

We've done a few BBC Procharger setup's like that. The drivability is alot better with injector's than the carb.I would think the 4 barrel FI would be a restriction compared to a 90mm or 100mm TB.

On a carb intake, would you see the std TB being a restriction at all ? if using one of Aaron's stylke intake elbows ?

Ive ordered an edelbrock intake, but if and when I even fit it, was intending using the std TB again, to keep costs down. Need to fit the intake first, to see how much clearance I will have for an elbow first though. I think I should have decent space, certainly more than your Camaros anyway.
If I ever make close to 800rwhp, I'll be more than happy. inf act, Id be jumpin up n down lol
