Yeah I was looking at that yesterday. ive done a few calculations which I have attached. Im not sure how good they are. let me know what you think. Was gonna do the 2871R but havent had a chance yet.
Ive been fairly conservative on some of the figures though.Attached FilesGreg

Good to see my trusty old calculator is still being exercised !
I was hoping to find some time soon to revisit the old 'turbology' paper and spruce up the calculator. Anybody got anything special they would like covered ?
I was planning on adding a section on injector sizing, and the related maths behind all that stuff.

Its a top notch setup made just for high performace cars. 10 ultra fast gas injectors and 2 vapourisors. Can get you details if you want. I will be installing it in the next few weeks. Its om my urs4. Car will come back on the road with new Konis + EBachs, bushes, HP2 brakes, New carbon clutch, metal gasket, Rs2 manifold and petrol injectors, proper intercooler etc And the gas. Should be a bit of a upgrade

You can use the 0.82 but the benefits are not worth it on the turbo range until you get to size of GT30R ( 3076 )

Must catch up with you sometime and you can educate me in the ways of LPG - it seems to have come a long way since the early days. I know a guy running it on a Beemer 740 and he raves about it... But the big gas bottle in the boot still freaks me out !
