this is not a general question about compressor maps or how to read them. i need some very specific numbers. does anyone know where i can find volumetric efficiency and BSFC for b-series honda engines? anyone know where i can find the same info for the k-series? i did some calcualtions based off of this site http://www.turbobygarrett.com/....html .

according to the calculations i did, i found that a gt35r won't flow enough air for 500 horsepower (at the engine) on a b16. i know this is not true. i think that the parts of my math that were wrong was the volumetric efficiency and the BSFC (brake specific fuel consumption in case you didn't know). any help would be appreciated. thakns.

 

bump for info

 

Man your smarter then me I couldn't even do the math on Garret but i found this turbo calculator on stealthmode.com here's the link

haven't done that in a while.. but read through my replies in this thread: https://honda-tech.com/zerothread?id=1025485.. might help you if you're trying to calculate your own setup.. do pay attention to dyno graphs and overall experience from others with same setup.. its good to compare between whats on paper and in real life

 

thanks man. your just provided me with TONS of info. THANK YOU!

 

VE for Honda motors are pretty high. An H22 has a VE% of 102% at 7000 RPM's while an F20C has a VE of 112% at a little over 8000 RPM's. So a K20 is probably way up there too, with the peak VE happening at peak HP rpm.
