Here is a few of pics of my modified atomizers and how well they do that job, this is a customers jet undergoing some calibration and general testing. Can be set from 100cc to 850cc per minute @ 1.5 bar pressure.
Data logged air pressure and water pressure, testing flow modifications Works form 7psi to 100psi boost pressures < yes I have tested it this high http://www.youtube.com/watch?v=8Lizxy3XIY8 <video

I should have responded earlier, I was too pre-occupied with our new system launch.
Again, great set of pictires. You system will go far with such a good dynamic rangem, putting all the PPS (progressive pump speed) system maker to shame. Thay struggle to give a dynamic range of 2x. Linearily and atomisation are terrible. It is the right season to play?

Well Finally ! Tested & Finished *taken from another forum I posted up details, for reference this is a list of other cars at bottom of this page that I test to give relative performance in mild state of tune. Could will go even faster on same boost as at end of third gear it (last 5kph) got into higher EGT and the ECU increased the fueling (making engine too rich 10.6:1) to cool the EGT down (cost ~20rwkw in upper revs power), I have since redone the table to allow a higher EGT setting before automatic fuel enrichment will occur.
http://www.riceracing.com.au/vbox-ii...ing-tuning.htm Logged the SP this morning and did some back pressure testing for SMB on the mid section street exhaust. 3rd gear 90-140 time of 3.11 seconds on 14.1psi boost pressure RR Water Injected, Turbine speed 91068rpm 132kph = 0.443G < (10% more acceleration at same speed as ONE58 when I logged it at 12.2sec @ 118mph on street on 1.1bar boost on twins FMIC etc, driver only in car) Turbine inlet pressure 12.0psi Exhaust back pressure 2.63psi 6681rpm 11.36AFR EGT 985deg C Fuel pressure 64.98psi Full boost = 3700rpm Ambient temp 10.6deg C Inlet manifold air temp on fast acting sensor = 32 deg C need to do up the graphs, exhaust back pressure at 240rwkw on VBOX was 3.0psi @ 7500rpm (which I would class as quite good for 2 mufflers and a catalytic converter & plumb back waste gate set up).

Hey beautiful build, very well thought out and well documnted
So at 14psi boost your only seeing 2.63psi exh back pressure, thats very good. You also have a turbo inlet pressure reading as well (12psi) that'll be interesting to compare as I'm going to be running one to with a sealed ram air inlet to the turbo. This is on a landspeed bike so I'm hoping I may start to see positive atmoshere figures at top speed. Good luck with the car, it looks great. Ian |

Thanks for nice words I too have a ram air sealed air box for my turbo inlet, there is a carbon duct going down into the nose cone main entry that feeds the air box, I should fit up a pressure sensor there and do some high speed tests. The post turbine pressure I thought as you was pretty low considering it is fitted with a catalyst, plumb back waste gate, and two mufflers. Being 3.5" internal diameter probably helps that. Also at this low pressure ratio the turbine inlet pressure is lower than inlet manifold pressure which is beneficial for the engine. I did a brief test to 1.2 bar or about 18psi boost and this relationship held true there also. Look to do up some graphical form of the data and post up so people can have a look. At the moment I will be trialing a batch of 50/50 by weight methanol and water mixture (at a higher injection flow rate) to gain a bit more power and also have a mixture that is easier to ignite without loosing the amount of cooling I have at the moment. When I do the tests will update on that too. Here is a bit of other online resource of a good dyno test done on the topic (if equalized back to even boost pressures) there was a 6% gain in power from the blended mixture. Post number #1225 http://forums.nasioc.com/forums/show...934903&page=49 details follow on after this post.

I like your thinking
Sorry to use your thread but here's a couple of pics showing the ram air inlet (RHside leading edge of fairing) which is sealed when the bellypan is in place. Thats a GT35R behind the green ducting. The under sump exhaust has yet to be finished, hense nothing leading into the silencer!! |

Looks unreal no way I would get on that though :lol: serious lack of skill on two wheels :lol:

Last time out I toasted a motor at 230mph, luckily it didn't seize just ate itself very quickly !

Thanks Richard :smile:
I really have my heart set on it sitting on a steady 1.2 bar or 17.5psi inlet manifold pressure and when the weather cools down here maybe try 1.4bar ~20psi, I will update the VBOX3i testing figures once I get my hands on the methanol and mix up a batch. All levels I have run before in my old cars and in customers ones........ just being too cautious in this one for some reason. Tested the compression of the engine after 1800km and its good for a rotary at around ~122psi @ 250rpm (front and rear rotor same) cranking speed. Will keep an eye over this long term. I changed the porting specification to give the engine much more mid range power and not concentrate on top end power so much, it is quite fast on road despite relative low levels of peak power. I am projecting it will have a honest 480bhp to 500bhp (at the higher 1.4 boost setting) but will see what happens when I get around to testing this.
