Just wanted to know how high of a boost I can go with the 450cc injectors. I'm currently thinking about going 750cc or higher. Right now I have the deltagate wastegate, thinking of going tial soon too, but for now, I'm just wondering if any of you would know how high of a boost I can go with the 450cc injectors and the deltagate wastegate?

deltagates are rated to be able to control boost on vehicles that develop 300-400 hp, according to their website. It's a very small valve, something like 25mm, so you are going to get boost creep at higher hp levels. Get a nice big wastegate that can flow a lot more for better control without the creep.

450's are maxxed out around 300whp or so.
