88 REPU

I'm setting up a street engine (no porting) in a B2200, it has an RB header, Road Race exhaust (RB) an RB complete Holley intake, 12A distributor and other minor mods. I have a complete spay setup and was wondering if anyone has done this (I'm sure there are tons who have). I have set up NOS systems on many piston cars and have seen a few hatch pretty hard. Anyone blown up a rotary on spray?
Any limits - like a 50 HP shot or a 75 shot etc? How much juice can one of these babies take? The engine has about 60K on it and ran super in the 7 it came out of. I am planning on installing an RB oil pressure bypass valve (80 psi), a remote oil filter, a pulley set, and other typical mods.
I saw a video of an RX2 drag car from PR grenade really hard - they said that nitrous caused the problem. I mean the hood on this car blew open - pretty intense.
Thanks for any info anyone can provide.
