5.7 hemi supercharger
The previous thread reminded me. I'm kicking myself for not doing the 6.4 so looking to beef up the power a bit.
Putting a D60 in it now (the original issue with the 6.4 was that I didn't want to spend money upgrading the axle. Sooo.... any recommendations on superchargers?

Your fuel pump is designed to feed enough fuel for a 3.8 or 3.6 depending on your model year. Upgrading to a 5.7 requires more fuel and adding forced induction on top of that requires even more.
Obviously your current fuel pump has some bandwidth to support a 5.7 but it wont support a 5.7 with a blower.

For those of us in the world who can't get e85 look at the Snow methanol injection kit . You can a lot for times add an inline booster pump. I can't give you specifics on your application but people do it in other vehicles all the time.

Well I know I fed a 2500 HP engine for 12 hours on the dyno with a little Mallory 140. Worked like a champ and we were burning real close to 2 GPM testing. They are a little pricy, around $250 or so is what I remember paying. I definitely would recommend one of these, bulletproof and ready to run all day and all night.
It will supply the volume, and a 6.4 won't eat enough fuel to worry about pressure.
