Bypass fuel to the fuel tank with a tee in the line to the nozzle. Use a gate valve in the line between the tee and fuel tank to control flow to the nozzle....
It was just a figure. My turbo is rated for 350 k something.. I forget the measurement. but somoene told me that converts to around 60 psi. Its a big turbo...
Ball valves are horrible at throttling - you need a needle valve or a globe valve. Use the ball valve as a parking brake, to stop flow entirely. If you use a...
I had the tee in the line, the problem i have is that the pump wont pump at all untill it has some backpressure. When the valve was closed, letting fuel go to...
If it's an AC induction motor (like from a fan or something) use a fan speed controller to throttle the thing instead of a dimmer controller....

Hi Bret Please measure your compressor wheel and use one of the available calculating programs to get your max rpm , if its a decent sized truck turbo then max...
Measure the hole thing or just what I can get at with out taking off the housing? b/c I really don't want to do that.. Its Bran spaken new... Never even bolted...
The McMaster.com nozzles are of the 80 degree, full cone style. I located the first row of holes in the flame tube at a point where the edge of the cone of...
Then neither a fan speed control nor a dimmer control will work :(...

Hi Bret You'll have to remove the compressor housing to be able to measure the tip diameter of the compressor wheel, no use just measuring the inducer , as...
Hello everyone, I have recently got an Air Force APU with a Garrett engine in it. I have never experimented with a gas turbine before and I am looking for some...
if your jetpipe is not welded just heated into place, when it gets hot isnt there a chance it might come flying out ? is this kind of thing called a friction...
if two pieces are sized so they don't feally fit together, but can be pressed together, that's called a press fit. If you either freeze the inside piece, or...
- the pipe i fitted was taperd so even if i did not heat the flange ,it would of nipped up by leaving a 1mm ring prududing on the flange to turbo .and the act...
Denny, the GTP30-67 is one of the most easiest to operate small gas turbine engines I know of. It's really a plug-and-play unit. Yet they sometimes suffer from...
Hi all, I've having alot of trouble with the 555 timer ignition. Does anyone know a site to get the printed circuit board for the ignition circuitry. It will...
It's got so little circuitry that a piece of veroboard would be okay. I haven't even used any board - I've wired my circuit direct to the pins of the power...
do you think there would be a way to find one of these engines in australia? are they suitable for jet-thrust purposes, maybe with some small modifications? ...

hi, I sent a message to the group about 10 days ago explaining how I was having difficulty getting my engine to self sustain. My flame tube was extremely...
Hi Ben Congratulations :-)) Your "idle" pressure seems a little "high", but with small turbo's the losses are proportionally higher than with larger turbo's ,...
hehehehehehe.......just scooped a nice new turbo off ebay for peanuts. if anyone wants to make me an offer....otherwise i'll bring it along to the bov meet. ...

Congratulations. Kinda scary the first time it really runs. My T04 turbo idles at 5 psi, which is 50,000 rpm. It will sustain at lower pressure and speed,...
