not a truck but it is a truck motor

Wow is all I can say. I wish I had just the fuel system knowledge. That is the greatest idea of 99% of the time regular gas and with the push of the pedal it just flows into alcohol. Awesome just awesome.

right now there are 18 injectors wired up and ready to run. the 4 on the hat might get plumed/wired back in some day.
we made it to the dyno today. working thru the tune with the primary fuel system/injectors was easy. got up to about 5psi on pump gas. dyno was showing 402hp at 5500rpm and 5psi and was still going up fast. not bad for no intercooler and not peeking out yet. timing was at a conservative 15deg.
then trying to do the fuel phase we ran into problems. we could get the 2nd system to come on and the 1st to fade. seemed like it was going to work but once it tried going 100 to the 2nd set up it would start pulsing. i suspect one bank of the injectors were not on at all but it was too late to look into it.
kyle got some vid but i dont know if there was anything exciting enough to mess with. i will post up a pic of the log later.

very fun day at the dyno today. we suspected a problem with our 2nd fuel system and to confirm this we wanted to just tune the car on that system. sure enough it wasn't tuning well. sounded like it was running on 4cylinder once we got off idle. heat gun confirmed this. dynotom busted out his hand held duel trace scope 
and hooked up to one injector on each bank and right away showed we were not geting the "peek" of the peek and hold on one bank. ******* squirt 
this made us very happy since now we know what our problem is.
the phased fuel is going to be easy and work well once we get that fixed.
just to have some fun and to test out the rest of our 2nd fuel system we hooked up the injector harness from our primary fuel system to our 2nd fuel system and made a few runs. this means we were running off of only the 8 injectors that are higher up in the runner and we were running off of the big fuel system and on race gas. even though the car will never idle on these injectors it still idled pretty good and was easy to tune.
numbers... 508rwhp(mustang) at 10psi, no intercooler, 214deg peek iats. this was on race gas. we plan on running on meth, not race gas. meth should be good for AT LEAST 50rwhp more at the same boost level. at 10psi i think we are headed for 560+rwhp.
just for refrence the fairmont with an intercooled 5.3/mp70 and the same cam as we are running now was at 458rwhp@10psi on the same dyno. different tranny and converter but it is fun just to compare.
very fun day and thanks to tom at c@s
