The Holley mid rise dual quad was tested by Super Chevy on their 5.3l build, I can't find any dyno numbers on the injected version. I had an article on the same intake I have in on the engine now, it came in with similar performance as the LS1 intake and they suggest it's better suited for turbo or supercharged applications.
I also have an LS6 intake but I love the look of this thing. Maybe I will be the first to dyno it in turbocharged form.
This mid rise was released not too long ago as well.
This is from the release:
"Bowling Green, KY--Holley is proud to introduce the newest product in their modular intake Manifold line
Introducing the Holley cast aluminum Modular Mid-Rise™ Intake System. The Modular Mid-Rise intake utilizes the popular Holley LS1/LS2/LS6 cathedral port Mid-Rise 2 x 4 intake Manifold along with a purpose built plenum base Adapter and a Holley 92MM EFI plenum top which converts it into a Mid-Rise EFI intake manifold. With a max overall height of only 10.44”, the Mid-Rise Manifold is an excellent choice for street and performance street/strip applications with a powerband from 1,500-6,500 RPM and limited hood clearance. It’s perfect for a blow-thru or turbocharged application.
Being part of the Holley modular intake line means that this intake is not only available as a complete kit with intake, adapter, 92MM top and fuel rails, but all parts can also be purchased separately for a custom intake build. The plenum Adapter (PN 300-231) will accept all of the popular Holley Hi-Ram plenum tops as a foundation for custom induction systems."
I am hoping it helps retain some of the low/mid end torque and I haven't really built a rev happy engine so the compromise should work out.
Does anyone else have one of these?
