Would like some thoughts about improving the power in my truck.
Hello:
I have a 1997 Suburban 2500 4X4, L-29 Vortec 7.4, 4L80e, 4:10 posi. "Banks" complete truck kit with headers, 3 inch exhaust muffler, high flow air intake.
It has very heavy steel bumpers on it for wenching, holding extra fuel cans, or pushing another car or truck out of the way, 34 inch tires, 4 inch lift, Spring Helpers/Cheater in the rear. Nerf bars with steps under the doors. Nice rack mounted to the top with 2 wide beam and 2 spot,"Daylighters". Compressor on board 30 ft of Air line and assorted air tools, invertor and on and on.
This is my farm and roadtrip vehicle and has 210,000 miles on it. I have got the box to re-program the engine and the tranny depending on what I'm doing or where I'm going. I also tow a 22 ft trailor to haul my Tractor with a front loader and backhoe or mower.
I think you get the picture.
With the drive train set up I have it is a real struggle to get the truck moving under load, or to get the truck moving at high altitudes.
Should I be loolking for a Eaton style SC, they don't make them anymore that I know of but maybe find a used roots with a intercooler, Procharger, STS Twin Turbo's, or a cam, intake and heads?
Or?
Truck stock was 290hp/410tq I'm guessing now with the improvemnts maybe 380-400hp/525-550tq.
Would like to get torque up to 650-700 ft pounds. HP really doesn't matter. What is the best bang for the buck, given this information?
I look forward to hearing from you.
Thanks in advance,
Ty O'Neal
