Which Head

[Bansh-eman]

Are you using the Chariot right now? If so whats your opion on the three? Pros, cons, any performance or temp differences?

the pro desing and noss where the same thing, only differance was you have to change studs for the pro design and Noss you dont. I am currently getting my bike all back together so i havent got a chance to run my motor with the chariot head yet.

while the pro-design and noss head shells might be the same, the actual domes are not, and this is where any difference in power and reliability is made.

 

from my experience noss domes have a far superior combustion chamber design. they have been designed in 2 stroke simulation software, specifically for the banshee, and have the proper squish depth, width and angle to achieve optimum MSV, and the bowl is a perfect hemisphere, where as on the pro design ones you can see that the bowl flattens out alot more around the spark plug.

 

2 of my buddies have nearly identical set up banshees, only difference was one had a PD head with 19cc domes, and the other a noss head with 19cc domes. both ran on the same pump gas, same oil:fuel ratio, and jetted fairly similar too. the PD headed bike had constant issues with over heating and detonation. he swapped the 19s for PD 20s and it cured the problem. once he found out about my mates bike with noss 19s and how reliable it was, he put noss 19s back in his PD head, and it never deto'd or blew up again.
