I have a 90' f250 with a 4spd that i put a 6.9 in last year, i have turned the pump up 1.5 flats and have straightpiped it from the y pipe back, what else should i do to improve pulling power? I pull horses and campers a lot so any help would be greatly appreciated

 

Turbo it. This will improve your power significantly.

 

Figured that would come up quick, we just had baby 2 months ago so were a little tight in the financial department, i don't wanna spend a couple grand on a turbo just yet, hopefully this summer it will happen though.

 

i just looked at a post about a hypermax intake kit and it looks like u can easily make this urself and cheap. u can just reroute your intake tube cut a hole in ur firewall so it can draw air threw ur cowl. look at the hypermax cowl post on the site.

 

i found used kit for about 500 and less throw in a few of a rebuild is a good deal

 

Have you removed the soupbowl.
did you keep the stock y and run one pipe and what size is it.
Did you install a cold air intake. these can be fabbed way better than factory.
I don't know about the 90 models but the older ones the firewall is already a weekspot that we have to reinforce, so I would be hesitant to cut a hole in it.
I belive Dave S. and cheeper jeeper has pictures in their gallery of the cold air intake they built. I think cheeper built a Y pipe way better than stock. breathing is these things most important thing you can do.

 

Horsinround,
Welcome to FTE and the IDI diesel forum.

Air is the most important thing for diesels.

And that is why adding a turbo is the biggest single HP gain you can make.

 

what trans/gears/tire combo are you running?
careful with the fuel,once you see black,your wasting money out the tail pipe.

 

its not wasting momeny when u smoke out a hippy comvertable and a tail gater price less so worth it

 

hahaha.hey,not all us hippies like to smoke.

 

damn i cant wait for friday!!!. True duals! woot!

 

How much are you paying for yours? I got a price on having that done and they want $250.

Please post a sound clip too.
