This weekend at the track we will be baselining my car for some intake tests that we will be performing for a manufacturer of a single plane intake that contacted me and wanted to try out the intake on my setup.

The intake flows well over 300 CFM is expected to greatly increase the upper end power, while also maintaining the low end torque.

He tested his first one out on a solid roller 396 motor and went into the 10s with it. He thinks this will even turn out better on our motors. I agreed to test the intake after some tuning and whatnot was done on it. Here is the intake:













In addition to that testing. I thought it would be neat after responding to another post regarding the MAF meters limits. To conduct another test this coming Saturday. I will take the stock ungutted MAF meter off my fathers Vette and replace my gutted MAF meter with it. After making some runs as a baseline, see just how much difference the gutted MAF on a heavily modded motor will make.

What are your thoughts on these tests. Would love to hear what most have to say about the gutted/ungutted MAF. Guesses are welcome.

Lets see who gets closest.:lala:

 

It looks like my old Holley Strip Dominator manifold with injector bungs welded on it. It pulled nice all the way up to near 6500 RPM on my old 420 cu in stroker '70 vette. Made 510 to the wheels with a .610' solid cam, AFR ported 2.02 heads, headers, and a close ratio 4 speed running to a 4.10 rear gear. I'll bet the fuel injection gets better mileage than the 800 CFM Double Pumper did though!!!

EDIT: I notice you have the 190 AFRs. Are they ported? I had mine pushed out to 215 to be able to breathe with the larger cam and large volume single plane intake. Top end was much improved.

 

Bnoon,

Yeah that is exactly what it basically is. We think it will be the best of both worlds. A cross between the Super Ram and the Mini Ram.

We suspect the peak power will move from the Super Ram's 5150RPM to about 6000 RPM with the Edelbrock Victor Jr.

Definately we expect the results to be VERY positive. Even if we loose some low-end, which for us...might not be a bad thing. Hell I have a hard time hookin ET Drags, pulling the front off, and spinning through the 60' with a 1.52 sec 60' time.

Even if its a wash, the other benifits of easy to work on, all one piece, nitrous friendly setup will be enough for me to keep it.

Plus I think its a perfect blend of new technology, blended with old school.:hail:

 

Bnoon, forgot to ask you about your heads. But see you did include it.

Mine are 190 out of the box currently. So that we know will hold us back a little. But growth possibilities are definately available then if we know the heads are the bottleneck.

Right now both the 190s and the SR both flow in the neighborhood of 260 CFM. Taking the SR out of the picture and replacing it with the SP 300+ CFM intake will take that variable out of the picture and maybe force the 190s to breath a little more.

I should add there will be an adapter on top the manifold that will mount the TB. All factory plumbing will work fine with it. Direct Bolt in.

 

Heheheheh, I know what you mean about torque! Though I never ran any sort of cheater slick or anything on my vette, and even with the "torquelessness" of the Holley Strip Dominator, I had trouble breaking the 2 second 60 foot barrier on 255/60/15 Goodyear Eagle ST radials! Those suckers would pretty much spin the entire quarter mile. Wasn't good for ET's, but MAN! What a ride!!! Usually ran mid to low 12's (depending on how it did get out of the hole) at right around 120!!!

I think you're about right on the redline expectation until the heads get opened up. Before the winter porting job on my heads, we'd pull to a 5800 shift point on a close ratio 4 speed. The dyno had such a flat top to it starting at around 5500 RPM, we knew something was the bottle kneck. After the head porting, it ran up to 6400 shift point and a still fairly flat plane between 6000-6500. At which point the size of the valves, the headers I was running, and the carb all became a restriction.

 

Yeah I really think this intake is going to make the rest of the motor really crank. I am expecting about 10.8 out of it right off the bat.

My car hauls the first 1/8 like you would not believe, then it sorta tops off, but still pulling much harder than my other setups ever did. Christ its pulling better 60' than many of the other guys I know running juice on larger cube motors out of the hole and running 9s.

This intake is going to be the ticket I believe, or I am going to be very disappointed. One of the two.

Some say I will need more gear, but the manufacturer says they are wrong. He claims just as much torque as the SR. Guess he should know, he went from a 396/SR/AFR setup to it and that is what he experienced. So if that is the case, lookout.

His exactly words were, It gonna scare ya! *** I certainly hope so!

 

Yeah, with your good 60 times you shouldn't have any problems, even losing a little torque. Especially since you said it's having trouble hokking them up. If it bogs a little, just add a little pressure to the rear tires and I'll bet you see around the same short times. If you try a bigger slick, shorter gear combo, you might have to start worrying about dogbones!

So, any guess as to if this would work on my 305?

 

That's the Edelbrock Super Victor. Been out a year or two. Bigger and better than a Victor jr. Aimed at bigger cube engines. Why they have one for Vortec heads I haven't figured out yet.

You know that big torque spike at 3400 you have. Say good bye too it. Typicallly you loose 30-50ftlbs w/o the SR. Your loosing about 8" of runner. You should pick up a guess of 50 HP though. Did you go to bigger injectors too? I hope...
To optomize it, you may need a higher stall. You probably know this already. Just for the people lurking.

 

Scott,

yeah I think we might loose a little 60's although I am not so sure yet. I have mixed opinions. This weekend Corky and I both got new 60' times with a little anchient chinese secret tweaking. lol.

I nailed a 1.49sec and Corky after leaning his setup out. Ran 37psi with vac gage off, I was stuck at 42-43 psi as my regulator screw comes out at that point. Ran 11.7-11.9 all day. That is history on this swap of intakes. Anyways Corky got a bunch of new bests. 1.46sec 60 times, 11.02sec 1/4. DA about mid 2000s to low 2000s.

We were greatly pleased as I added 100+ lbs to my car with the new 3" full exhaust+ mufflers+ a roll bar/harness

Not too shabby. We are going to have to see how it goes with the SP swap. Going to be setup with 36# injectors, but eventually we plan on going back to 24#s. Just because. well see how it goes and then go from there.

Corky have more stall than I do, 3800RPM. I have to call Vigilante and see how/when they can up my converter stall speed. So we plan on running the intake on my car first, then Corky's. I might even go with more stall if the intake seems to perform well.

 

What's the lash and what is the duration rated at on your 242 cam? .015 .020?
I'd think your HP peak would be higher with that cam. The new intake will tell.
Good luck
