Is this a 4wd or 2wd class. I have been pulling for over 20 years and have not seen nitrous used on any pullers. Probly because it is outlawed. There are a few twin turbo 2wd's around the country. It works but they don't seam to do as well as the blower motors. A blown motor is just more controlable coming out of the hole. What do you have for driveline? What are the trucks in .the open class running now?The best bet in my book would be to see if you could sell your motor and and buy a good blown veney headed hemi. It will be more money but in the long run you will have something that is competive in not only that class but other also. I have been where you are. If I can help message me. I use to run a blown indy weadge head in a 2wd several years ago. Now we run a veney headed hemi. If you want look it up on facebook. chad haggerty
