larger injectors help stock high rpm??

[19b]

Hey guys, Would larger injectors help a stock DE that runs at high RPMs?? High rpms meaning constantly going from 4800 to 6000, back to 4800, and up again to 6000 or so, several times. If not what would help? I have K&N, crank pulley, & electric fans. Not on street. Thanks.

No, you don't need larger injectors for an N/A application. That is, unless you have a completely built N/A engine, then you might be on the verge of needing new injectors. Other than that, forced induction is the only reason you will need bigger injectors on a KA. As far as making more power in the 4800-6000 rpm range, a KA is no different than any other engine. If you want to stay N/A, intake, header, exhaust, cams, etc. However, the KA responds best to forced induction, I don't think I've ever seen any KA make more than about 175 hp to the wheels without it. Good luck.

Thank you, ziggy. I didn't think so, but I thought I'd take a chance here. Any other suggestions???

Keep the 270's until you need the 370's

I dirt track 4 cylinders, we can't turbo, I'm assuming that's what the 370's are for.
