yes, this money was spent to help support a stiffer shot of Nitrous. though as i've said, the bottom end would still be just fine (after hundreds of nitrous runs) if i'd NOT pushed the envelope so far. if i'd NOT run with over 1,500 psi of nitrous several times, as opposed to the 875-900 it's jetted to run. if i'd kept my octane higher. if i'd run the correct plugs exclusively.
but if if IF !
mistermike, the purpose of all swine coatings is a more succulent pig.
the purpose of Swaintech thermal coatings is to keep a few btu's out of the head and piston, and the lubricity coatings were just an (alleged) additional insurance policy. more heat kept out of the metal, the more that gets converted to energy, sent to the rear tire. less chance for pinging with a uniform thermal signature within the engine.
as to whether the bottom end is beefy enough, i guess that's the next discovery phase of this ongoing experiment. i'm gambling "yes". i was running a 64 shot last year and everything in the bottom end looks pristine, again, after somewhere around a thousand drag runs and several hundred of them "on the juice". rods, crank, bearings will be stock. i have a lockup clutch installed, as it was slipping with the smaller shot already.
i'm going to use an airshifter this year, and still haven't decided if i am going to undercut the gear dogs. probably not.
if i had a welder, i probably would have closed off the p.a.i.r. ports, but it would have been mostly out of boredom. i don't think they affect flow very much.
