So the new Drag pak is a efi supercharged engine with what sounds like a very large cam. I was always told that rowdy cams and efi don't play nice. How do they do this, and can it be replicated by us common folk?

Radical cams are fine with EFI as long as you don't rely on self tuning at idle. And new engines that have variable cam timing can make up for the problem at low RPMs.

I understand about the tuning. I don't think the drag pak cars have vvt but I could be wrong.

Look over on Yellow Bullet, there are tons of guys running various radical forced induction combos with EFI. Most are chevy LS based or ford but lots of it going on, and on VERY fast cars. You just don't see a lot of the mopar crowd on there. My drag week build plan for my 71 is to utilize that exact drag pack Whipple blower with it's larger intercooler on a stroked 6.1 block and utilize the Holley Dominator EFI to run the whole thing. The Holley is just one choice, there are several EFI systems out there capable of working in radical blown situations.

I run a pretty rowdy cam (NA) and EFI... for about 15 years. Some tuning required and with that works pretty well. No "self tune" with my combo.

Use alpha N tuning with map compensation.
