Re: Injecting prior to turbo comp' impellers
Ok I'll take a look without the pre-turbo jet then with.

Is the weather still cold in New Jersey?

Re: Injecting prior to turbo comp' impellers
Not today, a beautiful sunny 45 degree day. This thread got me pumped up to finish the install, just mounted the tank and pump, connected the level sensor connector, fluid lines and pump connector. Moved the jumper to DHB and turned the gauge on, the entire system is alive again! Time to go out for a ride a little later today!

Re: Injecting prior to turbo comp' impellers
Found this dyno at this location A 315 cc nozzle pre turbo and a 130 cc nozzle post ic. Nothing else was done. His spool was later, but his torque extended more. Is this the SHIFT of the compressor map that is talked about? Last edited by jmlegacy; 29-03-2015 at 01:25 PM. |

Re: Injecting prior to turbo comp' impellers
If anything, the nozzles position should be reversed. Also to make it a fair comparison, we would need more data like boost pressure to even make a call...

Re: Injecting prior to turbo comp' impellers
Man I can't wait to get on the dyno and even run some data logs around my .3mm pre-turbo setup. Just got a new clutch installed, need to break it in before I can really run 3rd gear full throttle logs. 450 miles to go.

I sorted out the data into an excel file and removed the insignificant data. Between 4250RPM and 5250RPM Post turbo map had more boost compared to Pre-Turbo and continues like that till redline but after 5250RPM PRE-Turbo makes more power and torque Could be turbo efficiency ? |

Re: Injecting prior to turbo comp' impellers
so, just activate injection past 5200 rpm...
I found .3mm pr compressor (Rotrex) having little effect. .7 mm worked well. I use 4x 0.3mm direct port now. In genera found the more water methanol I injected the more power I was able to extract. Sweet spot seem to be around 300 ml/min for my engine flowing about 1.5l of fuel per minute. injecting more adds not enough to justify the extra consumption. |

Re: Injecting prior to turbo comp' impellers
I'll be testing a .3mm jet post MAF (3 feed from turbo compressor), boost activated at 5psi.

That's my thinking too. I'm actually thinking of doing a two stage with a ~50cc nozzle pre turbo @4psi and second stage @18psi (190cc). Maybe 50cc not enough? I just need it to help me launch my autobox better. |
