The Sniper that has been out for a couple of years only is good up to 650 hp. We've tested them on 700+ hp engines and they work, but they do kill a bit of power. There wasn't a good solution for guys with 700+ hp engines but now Holley has introduced a new version of the Sniper with a larger throttle body and larger injectors. This one is supposed to be good for 800+ hp. I have one on order and will get pictures of it on the dyno once I get the test scheduled. We have a 700+ hp BB Mopar with Trick Flow 270 heads that has been looking for a solution. The owner wants EFI but none of the existing single throttle body kits could support the power.
