Draw through slant six turbo setup
Here is a quick update of this experiment/build. I have been using this setup to haul wood, various car parts, an in bed camper, navigate bad winter roads last winter, and I took it to a couple shows for fun.
Cold winter starts are difficult below around 10 degrees Fahrenheit, though it is better when the block heater is plugged in. Temperatures above freezing it works really well.
Winter driving with warmups, 10-13mpg depending on roads and speed traveled.
Lately with the weather now warmer, I have been averaging around 13.5 mpg, which is not bad for an old 4x4 without overdrive. With a set of worn out 31" tires I picked up off of craigslist on a set of rims I wanted, this turbo slant knocked down 15.98 mpg on my way back from Mopars in the Park in Farmington MN. That got me pretty stoked.
The exhaust with a straight 2.5 going into 3" pipe out the drivers side is pleasant and not to loud, no muffler, just a cummins like sound then smooth turbo spooling noises. I am already planning other turbo projects in my head, though there are a couple improvements this setup will see before going to something different eventually.
