What single turbo (s) you guys running?

guys, this is just a quick experiment to see if my calculations are anywhere near correct for mine! basicaly, if you could tell me what turbo you are running and at what pressure I\'ll work things back on the compressor maps & see what BHP you should be pushing. as long as I can find the maps for your blower

Please don\'t state your BHP as I want to post the figure the calculations come out with for you guys to look at & see if they are prety close or miles out

. basicaly I want to check to see if I\'m working things out correct for my set up

Cheers
Jono

GT35r 1.06, ported shroud, T4 divided inlet. Plan to run 1.3bar ish.

Sweet, I\'ll have a play with these later aslong as I can find the maps for each turbo

I presume that you all know the actual BHP of your cars?? No need for the hot side sizes... just working on turbo air flow rates at the mo

MX1311: the turbo maps are exactly the same... it\'s just the number you punch in are slightly diff with a rotary... slightly less bhp per Lb of air flowed than a piston, hence why we need bigger tubbys

Cheers guys

The T88 should be making about 650 probably, to get nearer to the 900 mark with a 13b you need a GT45...and 36psi of boost

lee mills · February 25, 2010, 10:43:18 PM

Cant see it making 650@1.2bar

rbs14a · February 25, 2010, 10:43:46 PM
