this is a superb topic with excellent info.I have some questions.Firstly i will introduce myself.
I have been running a 1550hp nitrous 600ci V8 in a class called Street Eliminator.Best time and speed in the 1/4 was 8.2 at 177mph in a 3000lb street legal car.Bearing in mind we have to use Optimax(with a commercial booster) and block treaded tyres. We have used the ERL system on the car but found after a while we didn't need it with the nitrous as detonation wasn't a problem(even with 600+ nitrous injected in 2 stages). I am now putting on 2 x 88mm turbos on a 572ci V8 that has to be run in the same class. We will be shooting for 2000+hp on Optimax and tetraboost. I am also going to use an air to air cooler because of events like the king of europe which has a 20min turn around and it would be impossible to use ice water in an air to water system. I will be removing the port WI system and moving the nozzles around.i also have a plate under the throttle body with 4 nozzles in that i will keep.these are .8mm. the nozzle system uses .4mm x 8.I will also inject a couple of .4 nozzles after the intercooler.Now,the pre turbo injection seems like a fine idea but what nozzle size would i need,and how many? How far away from the compressor are you injecting from? straight shot at it or against the tube wall?Also has anyone injected WI just inside the intake pressure port of the turbo? I know from previous experience that a 50/50 mix of water/methanol works great injecting with an rpm switch,and a sureflo pump and solenoid(which i still have). Also bear in mind that the water injection system would only be on for about 10seconds max in the burnout and low 8 to high 7 sec in the run.
Your input and info would be highly appreciated on this one.
BTW,a piccy of one of the turbos for the install...and yes,Holset have sized the turbo for the application,and are giving me their valuable input...

PS,could someone post a pic of a pre turbo nozzle placement?
