Holley accelerator tube vs regulator squirter

A while back, I read somewhere that the tube type squirters provide a little better atomization of the accellerator pump squirt by helping keep the stream more solid before it hits the booster and spatters. Kinda like the adjustable nozzles on a garden hose set on a narrower stream.

The regular type allows the airflow through the venturi to start tearing it apart before it hits. Because the stream isn't as "solid", it doesn't spatter/atomize as well when it finally does hit the booster.

The tube type is suppose to provide a very slight and very brief torque increase over the standard squirters because of the better atomizaion.

However, you can probably get better performance by fine-tuning the squirter size and pump cams so the brief accellerator pump action isn't too rich/lean and/or too short/long in duration. Once you get the squirter sizes and pump cam sizes/settings figured out, it might be worth getting the corresponding (but more expensive) tube-type squirters.

Squirter size and pump cams for 60' and jetting for MPH.
You may have to go back & forth several times to find the best #'s a both ends.

Gotta do EVERYTHING else EXACTLY the same way and watch the weather (temps/humidity/ wind, etc. as well as rpms, water temp,traction etc.) in order to get valid results from any changes you make.
