So from my understanding when it comes to the compressor section, an A/R ratio of around .7-1.1 would be ideal with a trim of around .55-.6 when it comes to the turbine section the only thing I know about it is the exducer area should be about 20% larger then the inducer. Is there a specific trim I should be looking for?
As for the fuel, I was wanting to use diesel or kerosene. I was thinking of using the brass oil nozzles on eBay. I was wondering how I should have them orientated in the combustion chamber. Should I just drill holes in the turbo flange and attach the nozzles so they spray directly down the combustion tube? Also should I add as many nozzles so when combined the max flow rate is achieved at the max rpm of the turbo? I believe the ideal fuel mix is around 60:1 is that by weight?

Hi Don't concern yourself with the comp A/R , Trim preferably less than 55 , turb A/R generally as large as can be if an auto sized unit , bit different with a large diesel one. Only 1 spray nozzle centred in the endcap spraying axially. A/F overall ~60:1 , by weight Have you read through this jetandturbineowners.proboards.com/thread/680/diy-turbinesCheers John
