jgkurz Posted October 16, 2002 Share Posted October 16, 2002 Hi all, I have spent many hours trying to analyze how much flywheel horsepower an L28ET would generate at a given compressor airflow LBS/MIN. I personally believe the L series engines are some of the best ever made, but also believe they are not nearly as efficient as a similar inline with a crossflow 24V head. My discussions with various non-Datsun turbo guru's lead me to believe that the L28 typically will not make 100HP per 10LBS/MIN of air. 100HP per 10LBS/Min of air is a general rule I have been given to size a compressor. My opinion is that if I wanted to make 400HP at the flywheel I would need my turbo to generate between 42 and 44 LBS/MIN. This assumes a properly sized intercooler, EFI, exhaust etc.... Does anyone feel differently or have real world dyno experience? Quote Link to comment Share on other sites More sharing options...
