You cannot compare dyno graphs done that were pulled in different gears.

 

i just did. . .depends on the type of dyno. . .in my case, it doesn't matter much whether its 3rd or 4th gear. If anything, perhaps a few 3-5 horsepower at most. ur trq will still pull sthe same, especially since my last run proved the trq curved increased at such a steady rate (constant slope) throughout all rpm range

 

I'm confused. Your base line of 242rwhp seems accurate. So your saying SAE corrected on a Dynojet, your final hp number after the MREV install is 281rwhp? How can this be if your peak number on your MREV dyno is lower than stock? Granted, we all know the MREV increases midrange, not peak. How did you come up with that graph?

Just for the record, I did pulls in both 3rd and 4th which resulted in the same numbers. The difference was 1 hp and tq which could have been a result of anything.

 

The 242rwhp was what i got on the sustained-load chassis dyno at engine logics. 281rwhp is approx what i woulda gotten on a acceleration chassis dyno, whcih is what is mostly used at the majority of places you dyno your car at, and is what magazines and car manufacturers use to market cars and their horsepower rating. . .this is according to engine logics, 18% difference. . .so they literally multiplied 18% of 242 and added that to 242, than printed me another graph cause i was asking them questions about the difference between differerent types of dynos. THeir answer to me was 18%, whcih seems a little extreme, but i said hey, what the hell, nice to have incase i dyno my car on a accelration type dyno in the future to see if it is true. Remember, this is a comparison, so the graph with the past and present runs are the important ones. the one with 281 rwhp is a mere theoretical calculation of what i could have possibly pulled on a acceleration dyno. If it could never be duplicated on a accleration dyno, then no biggie, 281rwhp still does look nice though for entertainment. ALso, understand, sustained-load chassis dynos will always output lower numbers than a accleration dyno, because they measure true power to the ground. . .as i said before, look up their website for a much better explanation. . .cause my experience with dynos is minimal.

 

Thanks for the explanation. I think the "sustained-load chassis dyno" is actually more comparable to Dynojet numbers than their leading you to believe. 281rwhp is a great number but a little unrealistic for your mods if you ask me. Just my opinion.... The before and after graph shows great numbers for the MREV in the midrange band. Thanks for posting.
