Hi
You won't produce 10 kgs of thrust unless you use afterburn .
If you must use liquid fuel , then a simple, suitably sized oil burner spray nozzle and automotive EFI fuel pump will do the job

I need more info/specs of your turbo to give you more specific details

Hey guys,
What do you use for tachometers? Cant get any that reads our rpm
Also, any gauges with reasonable price?...running out of budget

Tach , you'll find hard to find .
As for gauges , maybe cut back to just oil pressure , P2 pressure which can be used in place of tach , and TOT K type thermometer

Thankx you are a great help
I m flooding here with questions excuse me, hope after this build i can help others,
What do use for ignition system to ignite the spark plug?

Ebay , High Voltage Generators
or make up a spark unit using automotive bits , coil , condensor and flasher unit

I need more info/specs of your turbo to give you more specific details Displacement 3.9L, 3900 ccm KW 81/110 HP Angle α (compressor housing) 201° Angle β (turbine housing) 0° Compressor Wheel Ind: 40.1 mm, Exd: 67.97 mm, 6+6 Blades Turbine Wheel Ind: 65 mm, Exd: 52 mm, Trim 5.01, 12 Blades Pressure Actuator 1.800 bar Turbine housing A/R 6 Compressor housing 0.6 SDT Turbocharger HX30W, Model 3592015 It would be helpful if i get to understand these calculations and the theoretical concept behind it, many formulas seems to me that are based on experiments. |

Hi Thanks for the wheel sizes . Your turbine stage appears to be "oversized" with the turb exducer being 68% greater in area than the comp inducer, so your compressor might flow further into the high flow region of its map with lower efficiency , but without a turbine map its impossible to know what your 0.6 A/R turb scroll will flow ..............trial and error testing of the engine is the only option as theres virtually no maps available for Holset turbos and theres a lot of HX30W variants www.turbomaster.info/catalogos/modelo.php?base=holset&pagina=HX30W. You'll need to lock the wastegate shut Cheers John |

Hey guys,
Whats the arrangement is like for a fiber optic sensor like omron, how does it work, what are the components involved?

Looking to produce thrust more than 10kgf With a tiny 40mm inducer you'll struggle to get 10kgf of thrust....also, there's not much difference between LPG and kerosene with regards thrust. Smithy. |
