12R injectors
I want to upgrade my stock injectors because they are running close to maximum on the dyno and I want to be able to add some more gas next season. At the moment I've only tried a 60hp shot. Anybody got any info on alternatine injectors. Thanks, Keith

60hp dry? How much power are you making? Stock injectors are fine to 300+ rwhp.

call Wayne at RC Engr. They has several sets, you stock injectors is 30lbs(310cc)
They have some 330 / 440 and larger injectors. 330 should be fine, but the 440 are only a buck or two more

justoyz,
good to meet you at Memphis!
do the 330/440 fit without mod to the frame??? pretty close fit even for the stockers, eh?

Someone enlighten me a little on injectors.I know they are either open or closed and just regulated by time but will the size influence the atomizing effect by having more holes?Or is the smallest size to fit needs the best?

With a given fuel pressure the size of the injectors will influence spray pattern and the ability to control it effeciently. Small injectors are duty cycle limited on the top end.
Large injector tend to have some idle and drive issues.
To a degree smaller is better as long as you have enough. I think 85% duty cycle is the max recommended hp but many exceed that.
