Injecting prior to turbo comp' impellers

[snoroost]

I read a fair amount of this thread but I have a question is injecting pre turbo very good at stoping the deto???

Not sure on the effect on det.

People are more interested on extend the useful range of a small turbo charger.

You really need a fine atomized spray (~5 microns) to do the job 100% without damage to the wheel and even better if your intake system can be configured to shoot this into or near the center of the compressor wheel. Here is what I have fitted to my own car (my own WI system) but I have seen others use other vendors product with much less atomization and if its targeted to the right spot no wheel damage will result ever.

Another good use for pre-compressor injection, is the sustained high load, trailer towing. The CAC for these vehicles is in front of the radiator. The heat of compression is so overwhelming, T2 can easily be over 500 F (250 C) at higher altitudes. This heat load rejected in front of the radiator is enormous, calculated at times, over 300,000 BTU/HR. In short, the radiator can no longer function well enough to serve the cooling needs. It is possible to absorb 150,000 BTU/HR in latent evaporation across the compressor, and this is a large burden removed from the CAC, and hence radiator can perform adequately and keep coolant under the BP.

Here is a one application. An 8 nozzle unit. I did this article to show how diesel application differs from a gas application

I kept trying to tell people to use air assisted nozzle or direct the spray towards the centre of the compressor wheel. This simple message never seen to get through.

Excellent article. The advantage of pre-turbo injection idea will eventually come throught, but not soon enough.

Rice, interested in more pics of your airwater nozzle setup

Here is the completed RR air box adapter with RR WI nozzle mounted in it. < Before I made the retainer to hold the air/water atomizer in place. To these I fit my bespoke flow control valves and do the machining to the delivery side of the jet so they have the flow rate I require and also a bit better atomization. My one jet works is variable from 100cc/min to 850cc/min @ 1.5bar pressure.

The key is a large area to discharge into, and also to have a bit of pre swirl of inlet air, this combined with low particle size for your droplets and you will have excellent performance (at very high water flow rates as I and my customers use) and non visible long term effects on the compressor wheel.

You can see the RX2 in this video http://www.riceracing.com.au/Videos/...-injection.wmv and you will see one of my jets located on the back of the compressor cover pointing into the air filter void and against the oncoming air stream. This 13B engined car makes 600+rwhp (over 750bhp) on Optimax 98 Ron pump petrol and uses around 600cc/minute water flow rate. It has consumed well over 200lt of water and the compressor wheel looks just like a new one
