when choosing a cam what determines how lopey it will be at idle. what is the lopies cam you can put in a sd car>

mjr46

duration /valve overlap determines how agressive the lope will be

crueheadstang87

so the higher the duration and valve over lap the more aggressive?

mjr46

usually works that way!!

yea but with speed density we need alot of separation to get them to work well... sd cars w. cams arent lopey, end of story

well said dimebag

pimpinstang1

so no lopey?????? that sucks. hows on performance?

mjr46

probably squeeze with the right combo 270 to 280 rwhp out of a sd car......cause at the range you'll be pushin the 19 lb injectors close to their max duty cycle and for more hp after that you'll most likely need a sd tunner to alter tune for larger injectors

pimpinstang1

so if i want to drop 24lb injectors on my sd setupid have to get a custom tune?

you will have to lose the stock ecu and go with an aftermarket like megasquirt or xfi.
