flycutting and boost?

I did a search and can see that people generally say not to flycut with boost or nitrous. Has anyone actually done it and what were the results? I can't see how I can get away with not notching my pistons on my combo. Lq9 with lsa heads. Waiting on an adjustable pushrod to verify how much needs to be cut, but I believe it is going to be about .060 on the intake side. Exhaust is fine. I thought about custom pistons, but between the machine work and pistons, its about $2000. So looking for some real answers about flycutting first. Thanks

Of course you can do it and it, but any material you remove will weaken the piston. Generally not a good ideal with big power boost setups. You didn't provide much information about your setup to give a better answer.

What kind of power goals did you have in mind? What pistons are you wanting to cut? What fuel are you running? Compression? Cam specs?...etc.

My pistons were flycut, but nothing major. I'm running the Brute Speed blower cam and around 11# with the F1A. I've been using 93 octane w/ 100 meth. So far, so good!
