Question Nitrous...Edelbrock? Others?

Has anyone installed or seen this installed on a G/Z? I have seen the magazine articles and it looks like a nice install and effective system - seems to combine a simple dry nitrous system with a piece similar to the Emange concept. NOS has always been my system of choice but I am looking into all of the options for the new G. I guess another question would be how are other dry systems enhancing the fuel flow pressure in a "no return line" system? In the past I have done it with regulated (nitrous) flow to the regulator but I don't see that working here...
Thanks for your feedback.

look atthe power curves in the article. Look how the power drops off about 1000 rpms earlier than a stock setup!!!! Something is not right there. Nitrous usually shifts the power curve down a bit, but not 1000 RPMS!

I am talking about the curve for the 100 octane, hi HP shot.

Also, didn't the engine not even break the 300 rwhp mark with a 75 HP shot?

Dry sounds nice, but people are getting great results with the ZEX or NX systems.

I agree that there seems to be something odd happening at higher RPM but, not having seen an actual dyno sheet for an NX or other wet system (any help here?) ! can't say if that is related to the system or to other intake or exhaust considerations.

My last nitrous system had similar characteristics - NA it would make peak HP at 7200 but on the bottle it lost about 750 RPM at peak. The majority of this was related to the efficiency of the headers and exhaust but ultimately, allowed me to shift a bit lower and reduce the likelyhood of having the system cut out at high rpm (the window switch was set just below the rev limiter).

Any real world information would be apprecieated - dyno charts before and after, time slips with and without, etc.

Thanks again

The G is limited by how much fuel the injectors and fuel pump will provide at WOT before going lean. I have a Venom dry system and it only makes 290 RWHP with a 75 shot. I'm thinking of upgrading the fuel pump to see if I can increase the shot size.
