Competition Proof SAE Correcton Factor is BS for Turbo Diesels??

[Dockboy]

Most of you know my opinion of SAE Correction Factors when it comes to Turbo diesels. Especially when it comes to running nitrous.



Well, I had the oppurtunity to put my theory to the test in the past couple weeks. Two weeks ago I dynoed on David Dunbars Dynojet 248C in Tenn. The CF that day was 1. 04. Dynoed 574 #2 only and 758 w/nitrous corrected. Uncorrected actual power put to the dyno was 551 #2 only and 727 w/nitrous.



This weekend I dynoed on Kauffmans Dynojet 248C. The CF was 1. 00, or in other words, nothing. Take a guess what I put down in the same settings?? 552 #2 only and 729 w/nitrous!!!!



So you tell me... ... ... . did I mysteriously loose 22 hp on #2 and 30 hp on nitrous as the corrected numbers would indicate?? Or is it that the CF designed for naturally asspirated gas motors is not valid for forced induction diesels given the fact I put the nearly exact same hp to the ground at both locations despite the difference in alltitude and correction factor????



Lets hear what you think!!

I think your points are valid.

I think you know my answer Greg.

I have been saying this for years..... Greg, lloyd, and I were talking again about this subject this weekend and all were looking at the results of Greg's dyno sheets. The CF that run in the software just doesn't apply correctly to our turbocharged engines.

You guys are only saying that because you don't live in the mountains :-laf
