Well..that is basically my plan. I wanna bend a rod in half. That would be the shit.


As for the 1:1 regulator. I think you need that with the accel and 625's because the bell or even the super FMU doesn't adjust that low. I think i have read the lowest they go is 3:1 ... I would imagine that if you got 550's and used like a 3:1 ratio you could theoretically run that..but what i was thinking, is with something like a 3:1 ratio, and 20 lbs. of boost, you will be pushing close to 100 PSI through your injectors still. 47 base plus 60 in additional pressure. And why i wouldn't want to run that is because it is still not 100% reliable...not that anything really is. At least with 625's and a 1:1...fuel pressure is not as important as with our setups now and even with a 3:1. This just basically gives all the controll to the injector pulse width. Which is the way a car is supposed to run. Pushing higher pressure through injectors works, but it can't be good for them. I have read how they can be stuck open.

And as for worse gas mileage with 625's...that might not be the case. As long as the accel could shorten the pulse width enough, the car will still run in closed loop, bouncing back and forth between rich and lean. So, i don't see how larger injectors will make a difference. a larger injector would just use a shorter pulse width and a smaller one would need a slightly longer one, but it would still be delivering the same amount of fuel.
