Im going with 4 720s. rtec 2.x. omp delete. single 3in with down pipe ( just put on) debating on using maincat or not( noise thing) just ordered aem wideband and plan on porting wastegate( new rebuild on s5) should i do before break in or after? stock turbo, intercooler and port. any suggestions?
The real question is brand. Venom vs RC. After some searching it seems the venom are bosch style and RC are Rochester. I guess the spray pattern is different. anyone ?

ha ! going rc . I just read multiple posts about people getting venom injectors not flowing well out of box.

I still have a main cat, and my car is reasonably quiet until I hit boost.

port your wastegate now

RC and Marren are both two brands I've had good experience with.
Also don't forget about Bosch branded injectors

I can't comment on venom injectors since I've never owned a set

Rochester style (GM style) injectors have a ball/socket style mechanism instead of the regular tapered needle and have a very wide spray pattern because of it.

Bosch makes the disk type (basically a standard injector but instead of a single "pintle" opening it has a disk with multiple holes for better spray pattern)

keep them clean and both will perform just fine for your needs.

Although I don't know much about spray patterns mentioned, I can say that I like the RC injectors that came with my 10AE. Since there was some age on them, I pulled them out and sent them back to RC for clean/calibrate. I left the stock primaries alone.
From experience, I'll say they're a good company to deal with. Prompt correspondence and good folks on the phone too. They guy I talked to was very helpful and spent some time on the phone with me concerning sizing and HP expectations.

Anyway, liked them enough that I bought new RC primaries and just installed them this weekend.
just my $0.02
