Hi,

My workshop has been running a fully stripped out, drag FC with a Peripheral Ported 13bt engine and 3mm race seals, they had been using a 35/40 turbo with 1.5bar for the races, but have chipped off the fins recently. Anyway, they have justy matched a new turbo with an a/r of .84 for the compressor side, and have yet to find a suitable one for the exhaust side. Does anyone here got any recommendations on the a/r size for the exhaust side? Based on the above mentioned setup?


Thanks,
Francis
