I see the 4 barrel style is very popular, what about the big monoblade's? What in theory would ultimately be better? TB at the end of the elbow, or sitting on the manifold?

I am wanting to run something that I can stuff under a hardwood cowl and not have to hack too much of the car up. kinda like a lid feeding the singleplane. what are you opinions having done a certain set up, would you change anything?

i tend to steer towards not using an elbow on a nitrous car if you can avoid it. its just one more turn the air has to make before it enters the intake manifold. but, certain installs may need an elbow. i dont think its a huge gain or loss either way. my setup is in a 3rd gen, and i run a 3" harwood cowl.

thanks vtec, been really throwing ideas around seeing what sticks... wouldnt think the elbow would effect the airflow much, but I guess if the stock shortblock master says so I will heed his advice... whenever I get everything put together and in the car I will have a sure answer, but most likely will mimic yours and wither use a carb style filter or the elbow style for the street.. whatever fits better really. using a 3 inch harwood as well.

the difference is probably negligible.... 5-10hp or some junk. unless you plan on racing the car frequently, i would probably just run whatever made the best looking/functioning installation.

alrighty, car is going to do a little bit of both. at least until it get's to be a bit of a hand full... Guess I will figure something out whenever I have it sitting there in front of me. you know how it is...

Also if anyone is doing this conversion and wants to use an elbow I have a new Nitrous Outlet 860 elbow for sale.

That looks pretty good. What valve covers are those?

The gains are debatable, but it all depends on your setup.

Some have switched and gained huge numbers, like 30+ HP over an elbow. Straight shot of air without sharp turns, but that sounds very optimistic to me.

Others have lost power, since a monoblade actually flows more then most 4bbl tbs and an elbow, in essence, adds Plenum volume...which is very important on a high revving engine.

I think it was Ed who tested on an engine stand and with a rediculous 7" of spacers the motor was still picking up power on the top end.

another thing to consider is packaging.... a 4bbl style may pick up power over an elbow, but if your hood is 1/2" above the 4bbl tb, you may kill those gains and actually be worse off than the elbow. another thing to remember is how the air enters the tb.... it does not flow straight in, but rather up and around all sides of the inlet. (think of how water goes down a drain.) just some more to think about.

Thanks FlyinZ, the valve covers are the tall centerbolt polished ones you can get most anywhere and the shop that built my engine also had them engraved with their logo and milled down the supports on the inside to clear the roller rockers.

FlyinZ car's not done yet I'm in the process right now, my car is a a buddies shop on the lift we just removed the engine/trans/kframe last night. We have to transfer everything over to my UMI tubular kframe & tubular upper/lower a-arms and rebuild my t56 then we'll be reinstalling everything. But I'll post pics and numbers once everything is back together and running.

Mike, never noticed you never had to hack up your cowl! looks like a good solution to me. You got any takes on the 4barrel or monoblade differences, looking for any experience if you have run both or not... If I can ever get out of this country I can do a lot more footwork and see what certain places can do for me, like N20 outlet, they do a lot of custom intakes and may be able to work with me on something. Regardless, I am trying to do it right the first time rather than have to redo it 3 times and blow my already bloated budget.

I can't believe some of these intakes are clearing the stock hoods!

Is there any possiblility of being able to use a composite SBC intake then?
