Hi Guys
Time to start a DIY engine build using the reman. GT60 turbo thats been sitting in my shed gathering dust for the past couple of years whilst I've been developing the "micro" engines .
Info on the GT6041 turbo here....... www.turbobygarrett.com/turbobygarrett/catelog/Turbochargers/GT60/GT6041_731377_1.htm
with its ~106mm comp inducer, its a big bugger , mainly used on huge gen sets and mining dump trucks , often in multiples on >1,000 hp diesel engines ..............and large IC engined drag cars .
Compressor wheel is bore less, so ultra strong , compressor map has the uppermost line at a tip speed of ~1,800 ft/sec , though best power from the DIY engine will probably be developed at somewhere between 1,600 and 1,700 ft/sec , leaving plenty of buffer zone for any unexpected flameouts with the afterburner that could normally overspeed a turbo .
Expected thrust near 140 lbs "dry" and 190 lbs "wet" .
Evaporative fuelling will be used in the ~7.5"- 190 mm dia flame tube , six evaps similar to those in my 2 shaft kart build , it only had 4 evaps for its 1.8 lbs/sec mass flow , so 6 for the GT60 should be just about right . ..............it looks good on the drawing anyway :-)
Currently machining up a steel die to hammer out the flame tube's 2 mm thick stainless end cap over .
Build should take most of this year so will add pics as the construction progresses
Cheers
John
