How well would this intake Work???
http://cgi.ebay.com/ebaymotors/CHEVY...spagenameZWDVW
Was looking at ebay for various things and I seen this intake manifold ( I knew there was one but I haven't heard much about them)
It is a Dual plane design from the looks of it, but wonder how one of these would perform Vs a Single plane setup.
Looks like this intake has been used before to do EFI conversions check it out

Re: How well would this intake Work???
Bret I was hoping to hear from you on this, How does this intake compare to a stock intake manifold. I don't know the specifications on this intake manifold (runner length, plenum volume, etc) but it would almost have to be better than the stock design. I would guess there is a lot of meat on the inside of that intake to be ported, but I don't know. Bret have you seen one of these intake's in person.
Bret as you know I have joined the Forced Induction club and you told me not to worry about a different intake (my LT4 from Ron), but it seem that tuning can be made easier with a dual plane, single plane design since there is better air distribution and there has to be some type of gains surely even in a FI setup. I also feel like my intake is chocking my AFR LE heads that have a big flow increase on my Ported LT4 intake, even though I am FI I would like the intake and heads to be mated well together (does that make since)
Bad95 on here stated his car gained 70RWHP througout the entire RPM range over an LT1 intake on a FI setup, and a Gm high tech car about 4 months ago (I will see if I can get the article) said he gained 50RWHP with his GM Single plane over the Ls6 intake and then gained 90RWHP from from the Ls6 to GM on his d1SC car.
Bret you know I trust you I am just trying to further my knowledge, (aren't we all)

I see here Summit sells this intake, $175 for EFI conversion and $200 for the Elbow to accept a monoblade TB. IT may not have the Potential of a Single plane in the high rev's but a Blower car reving to 6200, this intake I would think would show some gain on the LT1, LT4 intakes.
Has anyone tested this Carb dual plane VS a LT1 intake???? Thats the real question. I would guess a TQ and HP increase going with the Dual Plane Throughout the RPM range.

Re: How well would this intake Work???
I stumbled across this earlier this morning. http://www.popularhotrodding.com/eng...ke/index2.html
Looks like the Performer RPM (LT4 sytle design) did pretty good against the Super Vic and Vic Jr.
I may be completely off on this, but it does some seem like maybe GM's car LT1 nad LT4 intake is what some of the h/c cars need to get the extra amount of Hp and TQ. 465RWHP may be the norm on a LE2 h/c setup with a Ported GM dual intake with a Elbow and 58mm or monoblade TB who knows???
But I may be willing to find out.

Re: How well would this intake Work???
NO NO NO NO NO NO with the dual plane on a EFI setup.... and let me SAY IT AGAIN NOOOOOOOOOOOOOOOOOO!!!!!!!!!!!!!!!!!
The concept of a dual plenum intake manifold is for use with a fuel metering device that requires vacuum to extract it out into the system at low speeds. CARB!!!!! When you have a injector aimed at the back of your intake valve and pushed by 44 lbs of pressure you don't need to worry about that.
The reasoning behind that test and how things performed deals with the intake manifold sizing, the extra lower RPM TQ gain from the small split plenum design of the dual plane, and the power level. Now if you did that test with a preped Super Vic with the right cross sectional area for the motor and ported the plenum the setup would have run much better. Hell up the cubes and RPM range and there would be a different answer as well. The Performer RPM Air Gap intake is a intake that does excellent out of the box with a carb on it. The Super Vic needs prep work, it's actually designed that way so you can make it work with your heads, carb, elbow, spacer ect....
As for Bad95.... not a registered user. I know Sikora tried one of my intakes on his setup, but I never heard how it turned out. I wouldn't doubt that better fuel distributon and more air will help. Anytime you can lower the resistance to air entering the cylinder and in turn lower boost pressure with the same flow power will go up.
Ben you can do a intake that's not a issue, it's just not going to gain from the longer runner length of the Super Vic but it will work in distributon and flow.

Re: How well would this intake Work???
So with Bens setup not seeing above 6200 rpm would a regular vic jr be sufficient or would he actually benefit using a super vic? I know hes considering the Vic E atm, which is basically a vic jr already converted.

Re: How well would this intake Work???
No it's a Victor style, there are about 10 different single plane intakes from Edelbrock for a SBC. Why would you not want to twist the motor any higher if you can make more power doing so?
What's the rest of the package? He still a 383 and AFRs?

Re: How well would this intake Work???
Not to hijak the thread but has anyone had any significant gains on an N/A engine by ditching the stock LT1 intake and going with a Vic Jr and an elbow.Or does this apply like SStrokerace said why spin it higher if not neccisary is what i got out of that call me a dummy but thats what i got out of it just trying to understand

Re: How well would this intake Work???
Im in the process of gathering the parts for that now. Single plane and LE2 heads and cam(unless Bret says change cam). It will be N/A at first and then sprayed after the bugs are worked out.

Fred you nailed it. If the bottom end will hold it, and the blower is still working well up there with the rest of the parts it should work killer.
Yes on a NA motor it works much better.

Re: How well would this intake Work???
Bret I suppose this is Sikora http://www.cardomain.com/ride/827450/2
Bret I have a question about Joe sherman's motor setup
http://www.popularhotrodding.com/eng...man/index.html
How much of a difference if any will a Single plane make on the camshaft requirments for a single plane VS LTx style intake. Joe used a single pattern cam 234/234 around .591 lift on a 108 LSA, I don't know the full specs on the LE2 cam but I bet they COULD be similiar
I suppose this engine master shows people how well a Single plane can work from 2500-6500 RPM most of all the competitors were using Single planes instead of the normal Dual plane intakes, makes you wonder
Bret I just want to keep the revs down on the motor b/c with FI I don't see the need to kill it with RPM. Plus I had ASP make me a Custom 3.2 Blower pulley for my setup, and with the 7.625 crank pulley I am Spinning my D1SC at 60571 of the available 62000. If I rev any higher than 6200 or 6300 I will overspin the blower. I plan on running small cam, small gear, and small stall, I will let the boost and Heads make the power.
As far as cam I am comtemplating on a 224/230 using the 3100 high lift lobes, just wondering if the 918 springs will be adequate .605 intake (1.6rr) .603 exhaust (1.55rr) if not then goes in the 1.52's, Morel's or OEM for lifters??
That cam is real aggresive from what I see and usually runs out of breath around 6200 anyways. The motor is still 383 with LE AFR heads.
