Alan Johnson, owner of Alan Johnson Performance Engineering, issued the following statement regarding the current NHRA investigation of AJPE Superchargers provided to NHRA teams during last weekend's NHRA event in Pomona, Ca., and this weekend in Chandler Az:

“All Alan Johnson Performance Engineering parts are manufactured to meet NHRA specifications. NHRA is currently examining an AJPE Supercharger that was used by six teams in Pomona (Calif.) last weekend. Four of the six teams used the same supercharger during the 2009 NHRA Full Throttle Drag season, including the Al-Anabi Racing Top Fuel team."

Alan Johnson, owner of Alan Johnson Performance Engineering, issued the following statement regarding the current NHRA investigation of AJPE Superchargers provided to NHRA teams during last weekend's NHRA event in Pomona, Ca., and this weekend in Chandler Az:

“All Alan Johnson Performance Engineering parts are manufactured to meet NHRA specifications. NHRA is currently examining an AJPE Supercharger that was used by six teams in Pomona (Calif.) last weekend. Four of the six teams used the same supercharger during the 2009 NHRA Full Throttle Drag season, including the Al-Anabi Racing Top Fuel team.

“The new rule NHRA developed over the winter was not intended to exclude existing superchargers, but unfortunately it did. The area affected by the rule is a total of a half square inch.

“All Superchargers supplied to AJPE customers were made to comply with the new NHRA spec Friday morning at Phoenix. The fix did not affect the performance of the Supercharger; the current No. 1 Top Fuel qualifier (Doug Kalitta) is using a compliant AJPE Supercharger. Alan Johnson Performance Engineering is cooperating fully with the NHRA to resolve this matter as quickly as possible.”

Johnson's prepared statement raised several questions. NHRA supplied answers to those questions.

According to Graham Light, NHRA Vice President of Operations, the AJPE Supercharger in question involved two violations. The first was a technical violation involving a rule change dating back to October of 2009 which went into effect at the start of the 2010 season.. The second involved a procedural violation. NHRA requires teams to submit parts which don't meet current specifications to tech prior to use in competition.
