Engine Oil Underbody Protection?

The 2020 gt500 injectors are available for around $235 a set and will be easy on your tuner. Assuming 760 ish HP is enough on pump gas that will get you there. If you want E85 you will need to go bigger, what are your power goals for the truck?

if youre gonna go, go big I guess!

I would buy parts from MMR but I wouldn't trust them to assemble anything based on past threads - you'll either have no problems or a freaking nightmare.

Pictures remind my of my 02 Lightning rods let go. On my 2010 Whipple Rap , I run JMS Fuel Max pump booster plug and play. At WOT I run 11.0 to 11.2 AF ratios. I have the 47# pound injectors and run 3.125 pulley . JMS Link below it stabilizes voltage to pump at idle to 14.5v and under full boost it running about 16.6 volts to Pump PWM module. Made a big difference in throttle response and normal driving as well.

I believe the OP is running the 60 lbs. like I am.
Going down to 50 lbs. is the wrong direction.
Only JDM uses the 47 lbs. for their Tune but will use the ID 75 lbs. if you have the right mods.

I bookmarked this. I think I prefer it over the boost a pump solution. Either seems very simple and would get me to my goals as long as I stay on 93.

I am running the stage 2 60lbs injectors.

Blacktor what pulley size are you running? Do you know what your A/F was on this last run?

Thanks for confirming.
I believe between the ATI 12% OD, 3.125 pulley and the new Gen 4 compressor you definitely pushed the lower.
The new Gen 4 compressor is just so much more efficient.
In hind site, I have seen some post where going up in pulley size when upping to the Gen 4,
a larger SC pulley is a wise choice unless you have a built engine.
Doing the ATI 12% OD and 3.125 is OK on a Gen 2 compressor.

This kit shipped with the 3.250 upper

I would be interested to know when you pull the motor apart if the Boundary Billet Oil Pump Gears are still good.

I ask because there are three companies that sell Raptor Oil Pump Gears but only the TSS designed from L & M Motors actually use a special chromoly compound to increase vibration and shock tolerances, the others just claim heat treated chromoly.

My bad, I had 3.125 on my mind, I guess that stuck from when I read 1bad45ssv2's post

I've been wanting to do the ATI 12% for quite some time now, just to get the accessories to spin faster but probably, I might go up to the 3.375 from 3.250 if I do.

I have and used 3.650, 3.500, 3.375 and staying with the 3.250 for now.
I've also used the 63 lbs., 47 lbs. and staying with the 60 lbs.
The 47 lbs where a joke, IMHO
