7.3 turbo
tried searching through some other threads but couldnt find much, ive got an 89 f250 with the 7.3 and banks turbo on it. i just recently turned up the fuel pump and noticed a good amount of difference and power off the line. but im looking to see what else can i do to get more power out of the motor but still keeping some cash in my wallet....dont want it to be a drag truck, its gunna be a tow truck.

do u have gauges on it? pyro, boost, engine temp are the three i recomend. dont trust the stock temp gauge.
max psi for boost is around 12, any more and u are just heating the air. do not let pyro temps get about 1250-1300 if the probe is in the manifolds. and u prety much did as much as u can without spending anything. |
BB injectors and ditch the Banks intake and go with K an N

adjust the rpm governer on the ip itll let ur moter rev up to about 3800 wot.
|
how do you adjust the rpm governor and what exactly doed it do?
|
dont do it. no real need, no more power is made up in high rpm land. just harder on parts.
|
i beg to differ, i did it on my last 7.3 idi with the zf5 speed and i saw a difference in my power at the higer then stock rpm range
|
how much more power? is it worth doing? make it easier on the truck when pulling?
|
peak torque is made around 1600 rpm. and after 3000 rpm horsepower curves drop. only felt like more due to engine spinning over speed. i would only turn up gov IF the bottom end was balanced and i had PSD valvesprings. but no need to turn it up other than to abuse more parts.
|
my truck had the zf5 so wen id let the gears wind all the way to max i could run that gear a little more then normal. i noticed it when i pulled my boat (6500lbs) after i turned the gov up i could wind 1st and 2nd out more so wen i switched gears it wouldnt dog out so much. the stock crank on the 7.3l idi is ballanced up to 4000rpm. it was free to do thats y i did it.
