i think this whole thing is too much hype and BS, whatever stuff. all this fuel system hype is a bunch of crap. i bet is something as simple as what everyone has been doing. the 10sec passes was done out of time,practice and lots of nitrous. look at many cars that are doing 10sec passes and check out their fuels systems, they're gonna be similar to what HRC is doing. Mr. Hahn is just a good tuner and if you look at his mods, it's almost as equal to a stage 3 system. he's got lots of experience on the track and lots of techniques which got him there. especially with 150shot. i'll just stick to learning on my own. eventually, one of us, can be at that level and do 10's without nitrous. don't get me wrong, you have to have adequte fuel to run that much power, but still i consider it as too much hype. if he has a way to make bigger injectors work with our stock computers, and i'm tallking about 600cc plus injectors and not having a timing issue, then i'll be impressed. other than that, i think it's pretty much what others here have. we'll see.
