Hello everyone!
Start the buildup of the "76/86 Turbojet"
It originates from a Holset HX60W
Turbocharger out of a Scania V8 truck
Its technical features are: 76mm comp inducer
86mm turbine exducer
It Will use jetfuel and high pressure nozzle instead of vapourizers
Updates Will follow with pics.
Cheers!!

Hi Stephan
I was only able to 50kgs from the TV84 with its 89mm inducer , some 36% bigger , so on a proportional basis you can only expect 36kgs if you flog the turbo using excessive rpm and temps , with an afterburning max of ~50 kgs
Cheers
John

FREE POWER !!!! STRAIGHT THRUST! is the only way to go. When you mount a transmission, that only means you do not have enough power.

hmmm.....im thinking about using 12v electric hydraulic unit for the needed high pressure fuel,i read it somewere here where that was discussed and i thought that it could be implemented into my engine build...any thoughts or recommendations of fuel nozzles etc, i was thinking about using HAGO stainless nozzles together with the high pressure hydraulic unit for good atomization of the fuel droplets in order to minimize the length of combustor, any thoughts of how short the combustor can be?, the flametube will be 150mm diameter stainless, outer combustor can will be 8" stainless, thinking of using between 1-3 fuel nozzles,it depends on what setup is needed.

You'll only be needing a single spray nozzle, flametube length maybe 300mm if you have good atomisation

what would the recommended max speed be on my engine?, i read somewere on the internet(CABOTURBO) THAT THE MAX SPEED FOR THE holset HX60 was 98000 rpm,that sound a bit too much to me, it is a modern turbo but anyway comp inducer is 76mm turb exducer is 86mm |

With a 76 mm inducer the comps exducer is probably ~100mm , so maybe ~85,000 rpm to begin with
