It absolutly has everything to do with PSI,..PSI has to recert these blowers,..so whether or not DMPE has made these mods before or after the recert and for HOW MANY YEARS NOW, of the blower, the blower still has to come back to PSI for recert eventually, and if they(the blower case) get a new cert with the mods then yes it has everything to do with PSI. Unless you are saying and telling me that DMPE is also authorised to recert PSI blowers too, and pass them regaurdless of what the nhra rule book says,..that makes DMPE a resposible party also for scrutiny....?? So who ALL is cheating,.?? The manufactures that support the NHRA, and or the Nhra that has deemed a sole manufacturer of producing "theirs only" products for the drag racer. I am just saying,....this is not solely a Bartone/Jackson/Boggs issue,..it goes way beyond them, and deep into the red tape and what is ACCUMULATING up under the carpet WITH NHRA`s broom stick. Now Shhhhhhhhhh everybody, be very very quite dont say a word ,..it will pass., All the while the alcohol class is getting the nail in the coffin and sent out to the Goodwill stores around the country, but thats more important than the illegal rule breaking activity within the association and their monopoly manufactures. There is nothing more to say,....NHRA NEEDS A ENIMA,..!!!!!!!
