I have the 825 Race Demon and I love it, just bolted it on and adjusted the idle mixture and it works perfect right out of the box. It is the drag race version too. Better top end power than the 850 Holley DP

Been very impressed and pleased with my 750 Mighty Demon

I did take it apart and blew everything out with compressed air before installing it

No, I ended up selling the EFI stuff when I decided to go back to school, which prompted me to get the Mighty Demon instead

I put a mech Speed Demon 575 on my warmed over 327. I ran the car over 1800 miles this summer just on the Hot Rod Power Tour. WOW-whatt a difference over the Holley 600- Just adjusted the "idle-ease" and it has been running great-not to mention over 18mpg.

I am using the 650 mighty demon on my 383. Like Mike, I disassembled and cleaned out the carb prior to installation. I ran great right away, but I went and did a vacuum tune on the idle anyways and spent some time playing with the jets.

I've got a 750 Speed Demon for sale if anyone is interested.
