What airframe is it? Glastar 2 place
What is the cruise speed? I think he said 130 knts\ 60% power
What is the fuel burn at that speed? About 7 per hour. He also said he had plenty of engine left but the plane would not fly
any faster.
7galx6lb per gal=42 lb/hr
at .45 lb per hp/hr, 42/.45=93.3 hp (BSFC might not be that good)
If the 60% is real, that's 155.5 max hp
Thanks,
Charlie

I visited with a local NSI subi builder here in Austin on Monday. This
guy has the most hours on a NSI conversion. About 735 hours in the last two years. He has had a couple of failure due to assembly errors by NSI in their last days. His engine is a modified 4 cylinder turning
about 200 HP. The package uses a single radiator with 735ci core and a
small oil to water cooler. He has closed the space between the two air
duct feeds to the radiator and attempted to radius the bends in the lower cowl ducts. I am amazed he is cooling as well as he is. He reports climb temps around 195-200 and cruise at 180 on hot days.

There might be a simple explanation for his ability to cool.
What airframe is it? What is the cruise speed? faster. What is the fuel burn at that speed? Thanks,
Charlie
