I'm going to disagree with you on that one. When set up properly, you're not going to grenade your motor at any greater risk than you would with a blower. If an injector/pump craps out on you, you're going to do the same amount of damage if you were running boost levels comparable to that of the nitrous, not to mention the fact that you shouldn't have had an inadequate fuel setup to begin with. You can't immediately stop boost with a blower setup, whereas you can with a cutoff/microswitch with nitrous. You're also going to have a much cooler intake charge with spray than you would a blower. Not to mention that he already bought flat tops, which is going to make his compression kind of high to be able and run any decent boost without one hell of an intercooler.
I'm more than happy to spray a 175 shot on my 12:1 sbc without forged internals, and I've been doing so for the past two years, without a single failure to date. Am I pushing the envelope? Probably, but I'm confident that when something goes, its not because of a nitrous issue because I took the time to set it up properly. Same reason I'll be more than happy hitting the $10k 434 with a 400 fog every weekend
