well took the truck on a 130 mile round trip today and i am dam surprised
filled up before i left set the cruise control at 82mph and cruised the whole way, stoped did my grocery shopping and filled the tank back up with 64 miles on the odo, took 3.3 gallons.
did the same thing on the way home but with alot of truck traffic i set the cruise control to 75 got home with 67 miles since i filled up and it only took 3.1 gallons.
so the truck is averaging about 19.2 mpg on the highway which is alot better then i thought it would do
hell the only reason i checked though is to figure out how far i could go on a tank of gas since the fuel gauge is no were near accurate.
anyways i ordered a gt45 turbocharger, 50 mm wastegate and some ex tubing to start a turbo setup on it. i just need to figure out how to fit a decent sized intercooler up in front of the radiator but it dont look like theres a whole lot of room.
the plan fo rnow is going to be to replace the engine driven fan with an electric unit to clear up some room infront of the motor, then im going to flip the stock cast iron manifolds and build a merge pipe off of those to the turbocharger
im going to have to watch the boost level carefully as the stock tbi injectors wont handle much power over stock but im just looking to increase mileage just a tad and pick up some tq for towing, the first 4 psi will bring me back to stock powerlevels at sealevel , and im prolly going to set it up for 7-8 psi total
