I was just commenting at this level as that’s what he mentioned. It sounds like he wants to keep the factory pistons. Here he can achieve his goal pretty cheap. I don’t doubt the ability of a magnacharger to run cooler when tasked to make a lot more power than the OP is inquiring about

Yep. I am talking about overheating the car. I don’t believe I ever said that. If you are interested in a dyno number that means nothing that is one thing. If you are interested in the performance of a 600whp car, that is another. Take the 600whp car with the LT4 blower and go run the quarter mile. You will not achieve the same performance as another 600whp car with a different option because IaT’s Will be higher with the LT4 blower. On paper, the LT4 blower will show a similar torque curve, similar boost, and similar power numbers. Almost identical when you only pull in 5th gear for 5 seconds. I am also saying that is deceptive.
I am not saying the car will overheat. By heat problems, I am suggesting the LT4 blower will result in increased IaTs that will not allow for performance you would expect from a 600whp car. If you are only interested in a dyno number for bragging rights and you are never going to expect performance to match that number, then the cheapest way to get there is the LT4 blower. Sorry, I am not saying anything controversial here. Just pointing out that spinning a blower harder creates more heat and results in higher iat’s. The guys on this forum who have posted good dyno results with the LT4 blower have generally been running close to 10psi on the LT1. You will see on many of the threads when they post the results, I have specifically asked what boost level they were seeing.
