I wanna do a twin set up. I'm currently running a single hx40. The hx40 doesn't have much lag at all now. I was considering doing a set up with the hx40 up top and maybe a ht3b on the bottom. I know people running that making 80 lbs of boost. Is that the best way to go oe should I do something a little bigger like adam cornell with a s362 and a s480 which makes 100 lbs. I just don't know how much lag that will have. I was maybe thinking of using a hx50 up top with something else on the bottom but I just don't know. Its a street truck that I drag race sometimes . I don't mind some lag but I don't wanna have to sit and wait awhile for it to light either. Any help would be great. Thanks for your input.
