Technical Plenum size for Flathead blower intake

As Bored&stroked said Tom Roberts intake. Take a look at historien web Page.
The hard way is to make something out of some aluminium ;-)

 

Still a work of art Kjell

 

Blower purchased... next will be intake creation.

How tall is the TR Design blower intake?

 

The manifold base (without an inter-cooler top) is 4" tall. The plenum is about 17" long, 6" wide and 2" deep - though the raised "port section" sticks up in the middle. I have not CC'ed it.

 

I am using the Roadrunner manifold with a Weiand 142 blower. about 4-5 lbs boost. 2 engines built the same dynoed at 278 H.P. 4.25 stroker modified Edelbrock heads,ported and relieved. One had Holley 650 Avenger the other MSD fuel injection. Dyno sheets were identical. With race gas and more boost they would go 300 H.P.

 

Would love to see the dyno sheets to review the torque/hp curve and O2 sensors . . . what type of cams were you running?

Maybe you can read these. Best I could do.
