Where is the injection nozzle going to be located?

sorry, easy target... ;) :lol:

 

You're aiming to get between 10 and 15% water to fuel ratio (mild to wild) at WOT...

 

Work out what flow rate your fuel injectors are at max flow, work out what that is per hour, divide that by 100 and multiply by between 10 and 15 to get what your injector size should be... 8)

beavis about 6 inches after the CO pot.

 

I've got Red Top Injectors so whatever the fuel flow is on them!

Red tops are 30Lb/Hr MAX

[Blue_Joe 0]

well (30/100)x15% = 0.345

 

But I got 0.5, 0.6, 0.7mm injectors with my kit so does that mean that they are all too big??

I would think you'd need to convert #/hr to CC/min and then multiply by %. Should be (30*10.50)=315cc/min (315/100)x15=47.25cc or 4.725mm jet.

Cool Thanks bshell So using the nearest jet size I should use the 0.5mm jet??!!
