Mainly diesel with 10/15% petrol to get some volatiles into the mix, helps to prevent "smoking" at idle .................diesel with kero mix not used as much

This might help with your afterburner.... just run EFI pump full open, none of us before have ran any inline restriction, no need, if its is a little rich.... if it ever can be with an afterburner, over rich runs cooler and stop you or helps stop you melting it,
You will no when its running right, you will hear it, se video below for example, look how much more it moves when it screechers, also check out fireforce, or many big jet car, you can hear the screeches as the go down the track

In that case max consume is 12,5 gph and whit afterburn even 50 gph, is that all 37,5 gph going to afterburner or can I spray more to flametube when I use afterburner, example 20 to flametube and rest 30 to afterburner? I know it was quite an old post but still may help if relevant... You're better of using two separate fuel systems, one for the engine itself and one for the afterburner, it makes controlling flows etc much easier. Also, when using a single system for both, when you open the afterburner to main engine fuel pressure will drop and cause rather large rpm changes....not always ideal when trying to get the best out of an afterburner. I have 4 fuel pumps on my go kart....the first is a "real" helicopter turbine engine fuel pump for the Garrett GT6041 powered engine and 3 x bosch 044 pumps for the afterburner...one of the three pumps is used for the hot streak, the other two feed the afterburner itself. I use the spray ring and "falme holder" method for mine...but the "Step pipe" method also works well. My little 1/4 scale jet dragster also uses separate pumps for the A/B and also uses a hot streak method of A/B ignition. John will verify all here as he's seen them both in action in person. www.youtube.com/watch?v=1XqoYhSxKCgwww.youtube.com/watch?v=rd_m9fItlN0And here is the little car doing a run during an "RC speed meet" at my now local drag strip several thousand years ago...clocked at just shy of 235kmh..! www.youtube.com/watch?v=jzYxMccS66cSmithy. |

I love how its basically a flamethrower until the rpm is high another then it almost flies off the table 😂 |
