Fuel Injectors??

[Ghostnotes]

I finally see some time in the near future to put my C7 back under the knife. Been running my YSi-V7 on stock size pullies wayyyy too long. So its time to add bigger injectors LP/HPFP etc. The cam I have only has a +10% fuel lobe. With that being said, will I even be able to utilize +30% injectors or should I stick to the LT4's. I plan to go with 2 sizes below the standard upper pully size, and 1 size above the stock crank size. Also, as of now which injector would you recommend?

If I had to do it all over again I would have went right to port injection. Check out TooHighPSI’s website. That eliminates the cam lobe sizing and expensive DI injector/HPFP nonsense. Your cam lobe only being +10% will severely limit what you can do otherwise. The port injection system will let you rock and roll. You’ll still need your low side beefed up. LT4 in-tank with JMS voltage booster is a pretty solid setup that will take you to 750-800 WHP before running out of steam.

Agreed!
