A Swamps modded idm, 1.0 exhaust housing, and beans custom tunes. I'm thinking these things combined will put me at 300-320whp or so, and 600-650ft-lbs maybe? I think these mods will help me off the line and spool much quicker, and I think towing in higher rpms will be even easier than it is now.
Unless you are planning on installing an intercooler (which you said you were not), I'd stay FAR away from the 1.0 housing if you are towing (obviously you are based on the thread title). The 1.0 housing will increase the EGT's because the exhaust can't get out of the engine as fast as with the 1.15 housing since the 1.0 housing is smaller. It is like trying to blow the same amount of air through a smaller straw, it will take longer.
Thoes mods will deff. Help towing but i dont think u will be at 300hp.. no matter what tune u get you cant really get any more then 80hp out of a tune even on the 140hp setting with stock sticks in a non cali. Truck
300HP at the crank is pretty accurate with just a TS chip on the 80HP setting. You have to remember, he has the '97 version 7.3 which is rated at 225HP at the crank from the factory. If you add 80HP to it with a chip, that would be 305HP at the crank.
Will he get 300HP to the wheels, hell no. There will be a lot lost in the drivetrain, especially with the automatic transmission.
I've heard from a reputable person that my 300-320whp estimate is gonna be pretty accuraute...
I prolly won't ever do sticks or an ic on this truck, no.
So you think that with a tune alone my truck will move out from a stop way easier with a load?
You must have missunderstood the "reputable" person. I would guarantee if they are a "reputable" person, they didn't say Rear Wheel Power at the 300 number. They more than likely said crank HP. The engine from the factory is rated at 225HP at the crank. By just adding a TS chip and running the 80HP setting will bump that to 305HP at the crank.
You should consider an intercooler if you are towing a lot.
The tune alone will help. The 1.0 housing will help get you going, but hurt you in the long run as the EGT's will be higher.
If you want help getting going, consider swapping in 4.10 gears.
REMEMBER, there is always a negative side to every modification you do. More HP means more heat from the engine; a smaller exhaust housing means more heat as well. You have to decide what is practical to your use.
Also, these trucks are rated at towing up to 18,000# from the factory in a dual wheel setup. I have seen what an OBS 7.3 can tow. If you are towing more than the truck is rated for, you need to reconsider.
