Message I finished with the water injection and finally got all the bugs worked out. I am currently running about 19-20 lbs of boost. I tried to up the boost a little more with no result. I have the boost controller turned up all the way. The best I can get is about 20 lbs. Maybe I should throw in some race gas and see what happens. I need to get on a dyno this month to get a better idea on where I stand. Last time I tried on the dyno this spring with the water injection I was having a few problems. Without water I was getting about 385-395 rwhp @ about 17 lbs of boost, being a little bit on the lean side. I hope I can squeze another 50whp @ 20 lbs of boost and 3 degree bump in timming to about 14-17 degrees with 93 pump gas. I would also like to try mixing my own water methonal mix and see what that does. I'll make a little trip up to a local race shop place up in Wisconsin to get some methanol. I just don't like using windshild washer fluid (25-30% methanol). I am not positive how consistant they mix that stuff.

I am not in the mood to pull the engine again just to swap out some actuators. The next time I do an engine pull it will be with some type of manifolds different turbos, little bigger, maybe 700bb turbos :)
