What about this intake. Since is already made to fit an lt1 wouldn't this cut the cost of some of the fab work on a super vic? Opinions??

 

A Super Victor will outflow that intake severely.Just depends on your flow needs.

 

24502592 is a dual plane manifold, not a single plane. Think Edelbrock Performer, not SuperVic. Big difference.You still have to put in injector bungs if you want to go EFI.

My $.02

 

Yeah I know you'd still have to put injector bungs in it, but could you not port it to flow as well as the vic?

 

Ported to ported the Victor still kick's ***.Ported to out of box Victor the Victor still win's.Depends on what ya need for flow and how much ya can stand to loose on your head flow.

 

That intake is basically a sheetmetal intake in cast aluminum form. That intake has a straight shot into the port, a Victor has to turn many times to make it TO the intake port. IMO it will outperform a Victor conversion by a longshot, Pops and I are building a normally aspirated 383 with very high goals horsepower wise, we did not cut corners ANYWHERE on this car. Depends on what you want vs dollars to spend. A Victor or carb conversion( I dont know why no one has done an RPM airgap manifold, that is the best of both worlds) is the best Hp per dollar.

Nope.

If you get the chance, compare a Performer (not even an Air Gap) side by side with a Super Vic. Think of yourself as a bunch of air trying to get from the carb/TB flange to the head. I think you'll see the difference. Also think about how you'd get porting tools into the entire length of the dual plane runners.

Even if you could port the dual plane, you'd end up spending at least as much money as for the SuperVic, and have less power. Remember the SuperVic conversion is for when you've maxed out what a ported LT1 or LT4 manifold can do, and need/want more runner length. You aren't putting a Vic on lightly ported stock heads, you're putting it on "Stage 3" AFRs or "Summit Flows"...err Trick Flows or heavily ported LT heads, at least at the LE2 level. There's a lot more work than just butchering....err converting the manifold. This is not a low-buck undertaking.

Edelbrock could step up with an EFI SuperVic for LT1s, but I don't think the market is there. That's bad for the average buyer, but good for the converter , and Vic gets to sell a manifold either way. The quality of Edelbrock manifold castings is good enough that Vic may be doing some GMPP aftermarket manifolds.

 

I see now. I was hoping this would be a viable alternative since I could pick one up for cheap from work.

This would going on a motor with aftermarket lt1 heads. not sure of flow numbers yet but they should be into the 280's+ on the intake

 

280 will make about 575FWHP. If ya loose 10%(sheet metal) its 518FWHP if ya loose 15%(stock)489FWHP that 15% cost ya 86FWHP.This is with everything else(intake,cam,ect.) being spot on. That's just about average for the builds on the board.

 

How would a super vic comparte to an lt1 or lt1 manifold as far as driveability. I know that it will make more power and torque , but I was wondering about low end tourqe or driveability.

The reason I ask, is because I know the super vic has longer runners which would help contribute to torque, but don't the runners have larger volume also?, and If so would the length make up for this in the low end throttle response and tourqe department.

Basically, I know the super victor will make more power and torque, but how do you think that a super victor and a ported lt1 intake would compare on a daily driver with heads and cam in a 355, under about 3000 rpm. Would the super victor be low on torque down low because of the single plane and larger runners or would the length and "ram tunning " effect make up for this.......... Or would the lt1 make more low end with it's smaller runner volume even though it has shorter runners.

Is the super vic's greater runner volume mainly because of length ,kinda like why some 15*, 18* etc heads, can be more streetable with a larger port because part of the greater port volume is in length an not just port height and width.

 

280 will make about 575FWHP. If ya loose 10%(sheet metal) its 518FWHP if ya loose 15%(stock)489FWHP that 15% cost ya 86FWHP.This is with everything else(intake,cam,ect.) being spot on. That's just about average for the builds on the board.

Ya want longer runners on an LT-1 and as long as the intake don't choke it or is one for a BB it won't change the drivabality much at all.Ya need to have the intake flow enough to get under the magical 10% loss as to what the piston see's. Now that's not saying to put BB port size on there to do it.

 

I wasn't even thinking about getting an intake, and now I'm set on it. I didn't realize I was losing that much power.

How good of a chance do you guys think I would have finding someone who wants to get rid of their victor setup?

 

Ya probably got two chances and ya know what they are.
Everybody that has them likes them but ya never know. Look around but I haven't seen any. Intrested in a set of Hilborn's? Complete set up except lines to tank.. 8 ram tubes through the hood-- bad ***--.Ya sure.

 

What is a hilborn?

 

Mechanical fuel injection same as on sprint car's.
