This motor is built and next step is turbo pipe fabrication. Original plan was Ignite E90 and a Chiseled ATA 1500hp intercooler. Thinking was this might be a dragweek car, but that won't happen. So now debating setting it up for methanol without intercooler. When I put info in the calculator, looks like I need ~400 injectors instead of the 220's I own. Or I could pay to have my Hiram modified to 16 and put another set of 220's in. New to turbos and not sure whether making the switch makes sense as I already own the ATA intercooler, but was going for simplicity in turbo routing Opinions? Do I need that much injector? Full Specs of motor, plan is to cap boost at 30 psi as it is not o-ringed.

Running a mechanic fuel pump you could pulley it for 95-100psi fuel pressure which would extend those injectors a long way

2x sounds right, many injector's struggle over 75 psi of pressure difference. ymmv
