Does anybody know if there is an advantage of running one type over the other?

 

a pintle injector provides a better spray pattern from what I understand, but a disk injector can not be locked from pressure..

so, disk is better for fmu setup and pintle is better for lower pressure setups i.e. standalone/hack/etc

 

A pintle type is safe to how many fuel psi..I heard 60psi,think that's right?

 

anyone have more information on this?

I was looking at that site and just want to know if they are **** or if they are as good as pintle injectors.

 

I found this written by a staff member of RC Engineering.

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">Peak and hold injectors are fired at 4 to 6 Amps, through a ballast resistor, and then fold back to 1 - 2 Amps for the duration of the injection event. They are also known as "fold back" Injectors. Peak and hold injectors are faster responding than Saturated injectors by as much as 1 to 1.5 Ms. They are activated with more power at opening than the saturated types (4-6 Amps vs. .75 -1 Amp.). Peak and hold injectors will maintain injection delivery, cycle to cycle, continuity more accurately than the saturated type. This is particularly true and even more important in high-pressure (75 - 100+ PSI) systems. The higher Hydrostatic loading at excitation requires more amperage to initially activate the injector solenoid and properly maintain complete opening. Peak and hold systems are more expensive to manufacture because they require one computer "injector driver" per injector in most applications. This is a design requirement in Sequential Fire Systems where each injector is fired at a very precise, pre determined, time in the 720 degree 4 stroke processes. P&H injectors are also wound with copper wire instead of brass wire. </TD></TR></TABLE>

What do you guys think? Is what he saying biased or true?
