We managed to get into the 12:1 range upstairs. Fuel pressure was holding steady at just over 60 psig. I think the pump mods did their trick...now we have to see how long those mods hold out. I see no reason they won't go a long time as it can all be cleaned up and there is nothing to wear out. I still have to do some mapping down low...I have a spot on tip-in at light loads that seems to have me stumped right now, but I think I know how to get rid of it.
I think I have a G-Tech in the car somewhere... I think the better test is the "streak test". That's where each person gets a ride with a fresh pair on and we measure the size of the streak upon completion of the ride. No joke...I built this car and it STILL scares me sometimes when I drop the hammer on a back road. 600 HP will get you in deep very fast. When you drop the hammer at 50 MPH in 2nd and the back end comes out on you, it can get very interesting.
Olson...is it true you made a big streak after riding in the Murphy car last year?
