A few questions concerning preTurbo water injection

[mrx79]

Hi,
i'am reading here for a long time, but never had the time to install/test my WI system in my car. Today i made some first testruns.

As a background: Engine is a Honda B16A1 turbocharged with a GTX2860 .48ar T3 Turbine, running stable boost of around 1.1bar on pumpgas (98 ROZ).

based on RICE RACINGs threads i decided to go pre-turbo injection.
Currently installed is a 350ccm nozzle. I run my 550ccm fuel injectors at around 80%dc at redline and at activation boost of 0,6bar they have aprox. 23%dc.

I run normaly rich mixtures (i know propably too rich for pure water) of lambda 0,8 under boost. Timing is normaly retarted. Aprox. 0,5?/psi as a rough guideline of how much retard i'am running.

My first tests where without meth, but i will try later.

Maybe someone can say something about my experiences:
- i lost aprox. 35hp with my setup. no advance or lambda changes. Just add water.
- with water activated at 0,6bar, my spoolup is delayed by about 500rpm later then without water.
- the overall boost i lowered (with same WG and boost controller settings) by 0,1-0,15bar
