I recently got my 2018 Challenger Hellcat. I want to change out the supercharger pulley with the Hellraiser 2.72". I believe I will need to upgrade the fuel injectors. I will be doing the work myself and take it somewhere to get tuned afterwards. My questions are which fuel injectors would be best. Do I need to change the stock fuel pump with a double fuel pump. I am new to this so don't be brutal if I have something wrong. I appreciate any advice given.

2.85 hellraiser, 1050 injectors, fore triple, ported supercharger and snout, kong TB, SC blanket/spacers and FI interchiller This way you keep SC rpms down as well as heat generated. 18 psi. Proper tune.

I almost forgot the billet bearing support.

I'll also say most of this is overkill for an IHI super supercharger but I learned from a member here blkout that you don't want to spin these things too fast or they're gonna go boom.

I put a 2.72 on my Hellcat. I used ID1000 injectors and stock fuel pump. Depending on weather conditions (negative DA) I would max out the fuel pump. This was 93 octane gasoline. I went to dual pumps and it solved the issue.

Videos and data log are on my YT channel if you're interested.

thanks. I wish I could do all of that work.

Do you see a difference in gas consumption running that set up?

What's gas consumption? It's a 6 2L supercharged V8 😎
