Barry Grant LSx Cross-Ram?
 

If my memory serves me right, there was some hype about BG coming out with a cross-ram style EFI manifold for the LSX motors. Has anyone anything on this? Any news?

Don't know about BG but Beck makes a beautiful cross-ram.
However, all my research into sheet metal manifolds for the LSx has been somewhat disappointing. None have matched the Fast in performance for the LS1/2. And that's a non-ported manifold.
The LS7 can be improved with porting, Tony Mamo @ AFR is doing mine this month.
The sheet metals are all heat sinks as opposed to stock.
Several companies and individuals are working on the problem. See LS1tech.com for updates.

you really don't need/shouldn't use a sheet manifold intake on an LSx unless you are building either a very large motor or running very high boost levels that require the use of a 100+mm throttle body. There are too many other choices that work great. You've got carb style intakes and ported plastic ones. FAST will have a new intake coming out in a few months for the L92/LS3 that should prove to be great. These engines also don't need that much air if you drive it on the street. A 95mm throttle body is the max you want to use for a street car and those are reserved for the stroker motors pushing 420 cu in plus. Anything larger has bad off idle/off throttle characteristics and is sluggish. It'll only like WOT, nothing in between. You size the manifold accordingly and it becomes obvious the flow potential of a sheet metal one is not needed. People often lose track of air velocity in search of pure volume which leads them to believe bigger is better. Velocity must be maintained.

This new FAST manifold is designed to work with either a 90 or 92 to 102 mm throttle body. It should easily support any stroker motor designed for street driving.

Oh and no, I've heard nothing about this BG intake. Sorry to not stay on topic

Anyone got any more information?

WOW that's nice looking

LS-1/2 "Cross Ram"
 

Dynatek Racing is making a "cross ram" for a 1960 Corvette, with their 48IDF EFI throttle bodies.
This is made to fit the LS-1/2 head.
Their TBI's have the electronic injectors hidden inside the casting.

Would like to hear more about it!

Can this really be true : ( found on Dynateks web site )


No programming or dyno tuning required :wow:

Self-learning computer system automatically defines fuel tables :bow:

That Barry Grant unit looks nice

I'd also like to learn more about the Dynatek set up!!!
