How much will stock injector support?

[NWroten]

Curious to know how much hp/tq the stock injectors will support using stock CP3 and a good 'pusher' pump(fass or walbro). I plan on upgrading to twins and a good transmission in the near future and was wondering when larger injectors are needed. Thanks for the info. Love the site.

I know Luken made 650+ with stock injectors and CP3.

I've heard of alot of cracked stock injectors when trying to produce high hp, which is why most ppl upgrade. 2 benefits, horsepower and better materials. Also everything I read says that aftermarket injectors are better flow matched than the stock injectors.
