Continue Ignoring Edelbrock Cross Ram Intake Recently LSX Magazine and LS1TECH have been flogging, at Edelbrock's request no doubt, the Edelbrock Cross-Ram LS3 Intake. Continue ignoring it.
As shown in the LSX magazine's dynotest, dual throttle bodies are a major problem:
"we added the second Sniper EFI 92mm cable throttle body to the Edelbrock cross-ram tests, we flipped it upside down. We later learned that an inverted setup could cost you some power."
The author also "forgot" to mention that the Sniper cable throttle body would not fit in the upright position on (readers) right side of the intake, it could only be mounted upside down. This is a failing of Edelbrock to create a dual throttle body solution that actually works with this intake. The lack of development on a drive by wire (DBW) dual throttle body setup by Edelbrock makes this an orphaned part. It looks cool, but the added complexity and cost to create equal flow rates on a dual DBW setup means this part will continue to be ignored by most builders. If Edelbrock ever decides to create a dual DBW throttle body solution that has matched air flow rates and can be controlled from a GM ECU I might consider it for my LS3 swapped porsche. Until then, nothing to see here.
That dyno test of the intake in LSX magazine? With no details on the LS engine provided and no direct comparison to the LS3 intake, the dyno test is useless.

Same apply for NRE and PTR dual TB intakes then. I know NRE did not bring the Xram to the masses but PTR offers one and in fact a member in this section (may bad azzz intake thread) has the PTR however had MUCH bigger issues than worrying about an intake.
I was actually on the fence with the Edelbrock, even bought a Dominator ECU for that fact but. It does baffle me that someone has not come up with a flexible intermediate shaft between the two TB’s, but then again you do not see a lot of people on ls forums running this style intake.

Its hot rodding! Gunna have to get creative. I ve seen a dual dbw setup with a rod connecting both tb s. You could do something similiar with a cable driven set up too. Its trial n error, but it can be done without reinventing the wheel. Theres set ups that link 8 tb s together out there!
And there he is lol. I’d be real curious as to what this leftover horsepower would be, like splitting atoms minor leftover or like 40+. Appears the XR has both TB flanges at the same plane, the Edelbrock actually looks like they are kind of angled inward and not on the same plane which would complicate matters a little.

Mine is the Performance Design Carbon XR.
The PTR is a different intake mani by Performance Design iirc.
Im not 100% sure about the edlebrock set up, but if you have to have it kinda thing, I cant imagine a decent machinist or fab guy with access to a Bridgeport couldnt make it work for ya.
