Hey all, first post but I've been lurking for a couple months. A lot of really cool info on the site. I've searched though a most of the NOS threads and haven't seen anything that answers my questions. Basically I'm needing some suggestions for a small system to hit an index in a flat bottom drag boat.
I ran nitrous in the late 80's-early 90's... we used a NOS cheater system with a spray bar through the tunnel ram plenum. The motor was a 850 hp BBC and we only needed about 50-75 HP of nitrous to hit the 8.0 second index. We'd vary the n/f jet sizes based air/track factors and it worked really well.
Fast forward to today and we are back in boats, basically doing the same thing. We have a 588 BBC and based on what it ran on the motor, I'm guessing we'll need another 80-125 HP to hit the index.
Seems even a sportsman fogger is overkill for that small a HP. So what do you guys suggest, a small plate or what?
Does anyone still use the old school plenum spray bars? I don't seem them discussed at all. Back in the day, I liked the plenum bar set up. It was clean and jet changes were quick and easy.
Sorry for the long post and I appreciate any help.
