This is not that complicated.
Fact: Since VP has an exclusive contract with NHRA to supply the Nitro, for a hefty fee directly to the NHRA coffers and those big pay checks, Vp has continually raised the price of nitro.
Fact: VP has continually used the HLSecurity as an excuse to raise the price when the HL security themselves have denied this.
Fact: According to Don S. the cost of a barrel of Nitro is about $500+/-.
Fact: According to Don S. NHRA allows him to act as a supplier to VP so that VP can sell directly to the racers and Don S or Pro Nitro can not.
Opinon: It appears that there is something going on behind the scene we are not aware of. A power struggle of sorts.
Of course all this begs the question and that is; How how can Pro Nitro Sell to IHRA, other nitro racers and yes even NHRA racers for testing at a much lower price [while fully following all the HLS guidline] than VP??? So is Pro Nitro Selling the fuel as a loss leader or is VP using it's exclusivity to artifically raise the price of Nitro?
Stay tuned for the next exciting adventure of AS THE NITRO TURNS....
