Isn't the Super Victor for high RPM?

Conventional thinking of a Naturally Aspirated engine is what most of us have including myself. A NA engine will only SUCK or DRAW in so much air at a time. Think of it like this, if you are sucking through a straw you are only going to pull in so much air! Now hook it to your compressor and look out, you will see a dramatic difference in how much air you can PUSH through the straw by FORCE.

Ohh and if you research a SBM Direct Port Injection Manifold the SUPER VICTOR is the ONLY CHOICE you have because it is the only manifold available with EFI Bungs............Remember we are NOT dealing with a Chevy where it would take a month to decide which one to get!:toothy10:

Dont forget that this is a BOOSTED STROKER Build!! I don't know if you have ever had a Stroker Small Block but when you stomp on the throttle it moves Very Quickly through the RPM You will see 3500RPM VERY Quickly. If the Boost kicks in even then which most would say DANG that is High RPM engine, It will take off like a Rocket Ship for Damn sure no doubt... NA Strokers already come on that way WITHOUT Boost! Now Throw 15 PSI at it and frickin AAAA you better be ready for whatever cause you will moving some ground and VERY QUICKLY, I do know that!

It wont behave the same as it does naturally aspirated. Open plenum intakes are the best to use on turbo cars. I run a Holley Pro Dominator tunnel ram with a Hogans sheetmetal top. I would not use a dual plane intake, we had problems getting it to run right. I think it had to do with the way a dual plane flows and its restrictions, especially under boost. A naturally aspirated motor creates a low pressure in the intake port of the head drawing fuel and air toward it. A boosted motor pushes air through and can change the characteristics altogether. I would run the super myself.

I have seen alot of boosted applications and I would say 99% run a single plane. I got the idea to drill the intake from the turbo forums. Most of them were on the mild side though who did it that way. I just don't want the boost to kick in late is all. I guess that's where the torque of the stroker should over come that issue quickly! My 410 in the 70 comes on pretty quick NA, it sees 3500 RPM faster than i can blink it seems so if boost came on then I better be holding on tight and wearing my XXXL Depends when it hits!! Haaa

In my post about drilling the RPM Performer for injection bungs I was still a bit hesitant to do so. I had reservations in the back of my mind that under Boost Conditions the Manufacturer's RPM ZONE of the intake would be out the window like Chris "turbodart68 is saying. The Intake will be FORCED to accept the air. In an NA application it would be totally different as it PULLS the air into the intake in which would make the intake react TOTALLY different. Soooooooo, I will be using the SUPER VICTOR intake manifold and selling off the RPM Performer.

Just purchased the Super Victor Intake with the EFI Bungs.
