was up guys, havent asked questions lately but i wanted to know what will be the smallest gears or stall i can run on a procharger set up, i want a street beast and i am trying to get as much mph as i can, and i heard with the smaller the gear the higher mph ill get but then again i want a gear that will stay on the power band and not go all the way down, right now it has 410 gears, and a 4200 stall it pushed 761rwhp thru that and a 4l80 on a 6.0 with the F1a and 16psi, now its gonna be a 6.2 forged, ported heads, custom grind cam, the smallest gears i can get, the smallest stall i can get to my benifit, and e85 o and also 4.0 pulley to the 4.5 it had when it made 16psi, i want to be up there in the mph, lmk what should i do thanks in advance

 

Put whatever gear you need for the mph you want. And lock the converter.

 

There should be a gear calculater on here somewhere but I imagine the 4.10s should be pretty close to wat u need. Depending on how high u rev your motor and how tall your tires are.

 

3.42's 3600 stall and lock up the converter at WOT.

 

Im currently using 4.56 and a 3600-3700 rpm torque converter. I may end up going to 4.10s once I drop my truck and go with a smaller tire.

 

you think itll still work with the procharger.? since they say prochargers love loose stall and big gears

 

well you want the mph for the street or for the track? with those 20's i dont see how your going to do anything with all that power. if i were you i would leave it exactly the way it is, log your passes and see what RPM you go thru the traps at and how much if any your converter is slipping and then adjust your converter and gears with the data you get.

 

your willing to help me out with that.? i mean with the old set up before i would cross the traps it would "sound" like it was running out of gear, but if the stall will lock up at 100 it wouldnt run out of gear, and i really want the MPH for the street

 

bump, for a street machine!!
