I just got 4.10 gears installed a couple of weeks ago and now my car will hit the rev-limiter really quick. On the way I have a nos dry nitrous kit. My question is what safety equipment should i get to help save my motor when i accidently bounce off the rev-limiter. I'm planning on getting a wide open throttle switch and fuel safety switch. I have thought about the window switch but it will not shut off until 6,000 rpm's and I think my stock rev-limiter is set before then but i can't remember for sure. Also how bad will it hurt my engine when and if this does happen. I'm planning on running a 75 shot.
