Maxing out my injectors/maf ?

[zach44102]

Do you think my stock fuel system and MAF can handle a 100 shot with my cams and mods? I have a 155lph fuel pump and plan on installing a LC-1 wideband but im curious if anybody els is doing it without a tune and on fairly stock fuel system.

I researched this a while back when I was considering spraying mine. With the boost in fuel pressure while spraying, your 3.2 injectors should be able to keep up. If you are running stock MAF I would think that it would be maxed out as far as the metering. Not sure exactly how it reacts when this happens.

As far as I know Area91 is still running stock 3.2 injectors and is spraying 100 shot on his cammed 3.2.

All you have to do is change the nozzle to change the shot, right? If so, then why not test it with a 55, then a 75 and then a 100? You can wtch the wideband with each one. Also, if you need to pull timing with the bigger shot (somepeople do and some don't) you can use the octane switch to do so.

The 24 pounders gets maxed out at around 300+ crank hp. at 100% duty cycle.

Anyone who wants to spray or go FI needs a wideband , without one , its only a mater of time before someone melts a piston.

Cheap insurance , plus if you want to go bigger one day , you will have the tools.

And keep the stock maf.

Yeah so I guess the plan is to hook up the wideband and spray the 55, 75, and 100 shot stepping up each time and just keep a eye on the AFR.

Just spray till it blows.
