Ed. Note:  Wady Hamam or Pro Mod Wad as he is known in the sport as drag racing's main nitrous Guru. He has been involved in nitrous oxide injection almost from its inception especially with the Pro Mod division.. He is originally from the Buffalo, New York area and has been involved in all types of racing from flat track motorcycles to fuel dragsters. In his wasted youth he even raced a fuel funny car powered by a blown and injected small block Ford! He and his brother campaigned a front motored Top Fuel dragster and lost a race against Don Garlits at the now closed Niagara Falls Dragway. His advice about nitrous problems is highly sought after but he is hard to get to. He has agreed to answer one question every couple of weeks for Drag Racing Online readers. Email your questions to: promodwad@racingnetsource.com, and he will answer the question he finds most intriguing. (Original caricature Pete Millar)

Dear Mr. Nitrous,

Can you please tell me what is best to use: a dead-head type like the little Holley regulator or a bypass type like a Dave Koehler fuel controller?

Please, if you could, shed some light on this.

Dear Muddy,

Go with the Koehler bypass. You will save yourself so much grief you won't believe it. Dead heading is not terrible, but anytime you can keep the fuel system on the move you are being spot-on as far as nitrous tune-ups, and you are definitely keeping the fuel much cooler.

When you dead-head fuel it absorbs much heat from its surrounding components and burns much less efficiently and with less power.
