They were for a nitrous motor though. Are you planning on spraying or boost? Maybe just N/A seems like. I never had a problem. Just depends on what you are wanting to do. Apparently you are going N/A just looking at the RPM's you want to run. I would think that you would almost want to setup for a solid roller if you are that serious. If you are wanting it to just be safe then 7,200 is more than enough.
