Thanks for the info. I'm not trying to compare twins to a single as to which is better. More or Less does a single like this come close enough to what I want to avoid the time building the twins and money spent on them. Even being budget twins an using the stock charger the piping and second charger costs would prob be more than this single turbo setup. So with the timing and using the wide bowl Pistons there isn't a worry running that much advance. My motor is all stock never been opened. So I guess I might run the risk of spraying the walls? I'm trying to understand why I see most dd stay 16-17 degrees advance an no higher.

Bowl size doesn't change the cylinder wall width so it won't have an effect on when/where fuel can directly spray on the cylinder walls.
With stock bowls on a 12 valve and 145* pattern injectors, you usually can get away with 24* timing and still be inside the bowl when using thin 020" copper sealing washers. There is a difference between being in the bowl on the upper lip and in the bowl down where the fuel was designed to be sprayed. This truck got excellent fuel mileage before the bottom end rebuild and wider pistons, when it was running stock pistons, 5x014" VCO Budget Builder Injectors, thin washers, and 24* timing.

I've ran my 180 pump at a hair over 19 for 2 Alaska winters. Mpgs are in the low 20s on the highway - could be better if I was babying it. You can tell its trying a little harder when it's 5* outside and when it's constantly cold and dipping into the negatives I just plug it in with a timer set for 2-3 hours before I plan on starting it. Stock head gasket and I haven't tightened the head bolts down more. I like 19* more than I did when it was at 16*. 24* will be next

On the good fuel economy setup, the customer was running a Tater-Built hotrod HX35, I think it had the big 64mm HX40 turbine wheel and a 62 or 63mm compressor wheel.

Un corrected it was a mobile dyno I'm mot sure who's blue dyno pulled by a van I've only seen it 100 times. And I'm not sure of the boost it never cleared up and I'm 90% sure it has a boost leak at the intake. That power was made at 3500 rpm it's way out of air. S467 and 5x16s are going on this week.

I put the truck together to be fun on the street and that it is. The s467 is going to be a dog even with the .90 but i just want to see what the truck will do. I should also say the truck has another 30cc of fuel left.
