Ah though they were side feed darren_c??

[robbie@tdp.ie]

WTF man!!!! im trying to get these for that reason alone
and they will go nicely in the rb25 im building +2 more at about 120 a peice

not gonna argue wit said tuner but that would be my logic???

As I have explained to Darren the 550's will be fine up to 400 bhp. He only wants 350 bhp so 720's which are good for 575 bhp are overkill. Also it's not the duty cycle that the problem it's the atomisation of the injectors. The smaller the injector the better the atomisation of the rule the better the cleaner the bur of the file for a given power. 720 cc will work and can be mapped but in our opinion on a STD engine there is no need for more than 550 cc.

When it comes to RB engines the rules change allot. On a RB 6 cylinder engine 550ccc will do 520 bhp safe so unless it's a real serious drag motor then we would not go near 720 as they are too big. Also RB engines are way more sensitive to the Injector atomisation. This is why the cheap reworked STD injectors are so shit in them.

Are you serious about the Intake ? Probably one of the worst mods you can do to RB20 or 25. The real one is designed for drag only. It will kill all midrange torque a drive ability of the setup. Never mind the shit Chinese bad copy.

The injectors are very good and cheap but dont kill the car with an E-bay fake inlet..

Is it true Robbie that the standard up and over manifold on the RB20/25 is actually pretty good for its application?
