lol yep, beer.. me likes beer.. Joe

heres a pic of some other lunatic ruunning a homemade gas turbine engine (out of a turbo) http://home3.inet.tele.dk/kennethm/comb2p.gif Joe

oh and Ben my m8... check yer mail.. you have a surprise delivery of a nice excel spread sheet to play with... Joe

we used to make bombs when I was younger lol.. a group of us.. a Cisco Specialist, me and a local policeman.. Photographic flash powder, strontium nitrate and a hot wire fire in a close container JEEZUS CRIZE !!! also, Sodium Chlorate and Sugar (Before they added burn inhibitors to the...

and, if ya turbo the 172.. then.....

Ben, do a search on turbocharger gas turbine on google.com there are quite a fe wlinks with pics.. and some download sound files.. hee hee there are several pics with different methods of mounting the injectors.. YES... stand back when you add parafin LOL... oil feeds are discussed...

Oh Ben.. lol.. Let me tell you how to make your own gas turbine too... You HAVE to try this, its entertaining... get an old turbo of something... any... the intake for the compressor stage (air) is left open to air... the output of this stage goes to the exhaust inlet on the...

Chavvy, just to clarify a wee bit more what the guys have said. the turbo is 2 propellers to all intents, connected on a common shaft.. exhaust out the engine is fed to one side and turns the propeller or turbine. the other end of the shaft turns turbine completely seperate from the...

Yes, the dump valve is for the following reason.. you are bobbing along at 6000 rpm with 22psi of boost pressure Suddenly, you lift off the throttle.. the turbo is still spinning at maybe 150 - 200,000 rpm (yes hundred thousand rpm !!) and generating pressure.. where does it go ...

Hey dood, dont sweat, you do fine.. dont forget I have been at this for 25 years lol Joe. Each bit of work on the turbo mod I will produce the data and how to calculate it.

overall inefficiencies at WOT can be deduced by calculating a theoreticall torque curve for an engine of same cc as yours and same rpm assuming a VE of 100%. then transpose this over your torque plot and the difference from the theoretical line to the max torque peak is the inefficiency of...

oh Ben, I forgot to mention. a good ve plot from a torque curve will enable an accuare assesment of WHERE in the engine the inefficiencies lie.. by looking at the change in torque after a mod, you can see where you have improved it and that will point to the next area of work.. ie.. induction...

Mathew, just recalced the theoretical run with hardly any fuel, no spare wheel , and a lot lighter driver than me lol.. weight plotted total 2550 pounds. bhp 135 @ wheels. 87.865 mph terminal time= 15.513 s. There ya go.. Joe... but.. to bring it DOWN by 1 second (to 14.513...

Hi all.. Ben, the ve can never excede 100 - ie - the cylinder is competely filled. it is simply the fact that the charge is now twice as dense - twice as much fuel (presuming a 2:1 boost ratio after inneficiencies) and twice as much power. the ve can be caluclated from a plotted torque...

oooooooops missed the standard bit and figures used. here ya go ! Joe estimated weight = 2464 pounds.. (172 mk2) driver=200 fuel= 100 total for calculations = 2765 .. call it 2800 lbs BHP at wheels, estimated standing quarter mile time, terminal velocity (speed at end of...

Hi guys n gals. as part of the turbo conversion I am in the process of calculating the math to show performance gains on mk2 172. Later parts will calculate ideal turbine characteristics for this engine (to be overlayed on compressor maps available from the manufacturer of the turbo...
