Intake flow numbers For SBM

[MRL Performance]

And ported out the Victor 340 flows good. 600+HP N/A is not an issue. But I have found the Victor 340 kills the most bottom end torque of any single plane intake I have ever run. Also handy to know when designing a race car. Sometimes you want to soften up the bottom end to get traction.

To those of you who worry about what appears to be a lack of flow from the 340 Victor manifold.........OOTB it has 318 port sizes. Very, very handy at times.

And watch it put the smack down on some of the higher flowing intakes.

That's the reason I commented a "little disappointing". In stock form, it looks to me like a better intake for a 4/5spd combo, that can tolerate a more narrow band. Might have some left over characteristics from the early Torker/Tarantula's from my day.

Thank you for sharing mike. I enjoy seeing information like this on FABO.

Mike, were there any other mods to the gasket matched M1 (LA)
Also, have you ever tested the intake with the "tip" MoPar gives, to install a dam on the floor?

 

[MRL Performance]

I have run "turtles" on the floor. They don't make it flow more per-say, but help even the flow out from runner to runner. The best results I got using one was on a Indy big single plane for a 360-1 setup. The flow spread was around 50cfm from inners to outers. After the turtle was installed and massaged a little, we got the spread down to 20cfm.

Like to see what a gasket matched AirGap would do , compared to a crosswind , see if there really is a difference , or the Edelbrock is just more expensive .
And turtle , is that just something that goes in the intake that splits it into 4 chambers ?

The Edelbrock will be better.

A turtle is best described as the turtles she'll only miniaturized to be placed on the plenum a floor. They came in various sizes and shapes. They can be modified as well. They are not to split the chamber up. There not that large. The idea of the turtle is to help direct air and fuel flow. You can see the same type of idea on the underside of some carb spacers and the newer Holley carbs with contoured openings.

On the carb, top side, you can see the smoothed out entrance. On the spacer, underside, you can see the carved out 4 hole spacer. All this carving proves airflow. Same idea with the turtle.

Have you ever flowed a LD 340?

 

[rumblefish360]

Your welcome Jerry.

Dave, do you have a bone stock LD340?
I have one with the center divider milled down.

I'd send that to da-man for testing.

That would be a very interesting comparison, a stock LD340 and one with the divider milled out.

its got to be better on top end, the FAST guys do it to the stock 71 340 intake i did it to mine!

 

[rumblefish360]

I did notice that on the before and after with the intake. It was even noticeably sweeter all around with the big TQ on top. If your thinking about doing this, space the TQ up if you can.

That's right out of the MP Power book. I did that to a 340 about 20 years ago.
