Injector size and towing

[MikeGenova]

Have 50 HP injectors now and was looking to go bigger but was not sure on which size to go with and still be able to keep egts in check while towing. The most I tow is about 10,000 pounds and thats not very often. Have the Industrial Injection Towing Twins. Do you think I would be able to run 120 HP Injectors?

I have DDP 90's and a BD Special and tow a moderate amount. I think they would work well with twins. I struggled with the t/h not being able to lock out o/d. I now have the BD o/d lock out. I ripped up the grape vine with trailer in tow running about 1100 with a new cam. I did tow a heavy boat before the lockout and had a hard time keeping cool. Had to force down shifts. When the rpms where up temps are fine.

bad idea you already have the best size for maximum mpg and for towing. you show hamilton springs but you do not show cam. if you did not change cam this is a must. for towing and average use the pdr or colt is a little better than the hamilton, the hamilton is more suited to play. we think the reason the 50 may work best is because it shortened duration in the average driving load range. our test showed a 2. 2 mpg gain at 50 and back to stock at about 90, we think the drop is because it does not atomise the fuel as well

Sorry guys, I was out of town for a funeral. But no I have not done a cam yet. I picked up a set of 90s a buddy found me so I am going to see how it works out.
