AutoDyn reads WAY lower than Dynojet.



Seriously, I believe these results were "corrected" by the software to mimic Dynojet readings. See the graph title.

Wicked #'s and it peaks around 6k so you don't have to spin it to the moon

Oldsstroker is correct, these numbers are corrected to read as dyno jet nubmers.

The corrected numbers read with in 3-5hp, we have tested 4 cars btwn TSP dynojet and Dream Chaser's Superflow, but on different days to the are really close.


DC dynoed a c5 vette with full exhaust and k&N at 250rwhp!! after the correction with dynojet it went to 323rwhp, when the same c5 went to TSP two weeks later the car dynoed 326rwhp


The LE3 cam peak lower than the LE4, depending on how we set the A/F the car peaked btwn 6100-6200 vs 6000

I am trying to remeber but I am abouyt 95% sure these were the 561 castings. These 561's end up a lil smaller than the 643/374 castings in a few critical areas and will make the engine peak 100-200 RPM lower than the thicker castings mentioned.

Very nice numbers, congratulations. I noticed that you used the ZO6 MAF. Do you think that using the ZO6 MAF at this power level helped as opposed to using the stocker? Most tuners seem not to like using anything but the stocker, but I will be going for a dyno tune soon, and would like to use the larger MAF. What are your thoughts on it?

Not sure if its needed at this hp level, but i didn't want to leave any power on the table with a old , descreened stock maf.. We plan on putting a ls1 lid on this car as well, and i think with that a the 85mm maf, and the straight threw effect, that will yeld more hp. We were just planning ahead.

I feel the same way, I try to plan ahead. I think I will at least use a set of billet MAF ends when I go for my dyno tune. I also have a Monoblade sitting on my workbench that will go on as well, that will take the place of the AS&M 58 I’m running now. What does the LE3 spec out to, or abouts?

Sweet, now let's see some track numbers

Got any track numbers for any of those builds? That's what I like to see really

Pretty much in the same boat not sure what to do about the MAF as I've always used the larger billet changing the MAF frequency tables by about 10%. Just installed a stock MAF (no screen) for grins with stock MAF tables to see what it would do.

Off to a meeting in San Diego this weekend but going to drop off the car to A&S for a dyno session just to play with MAF's and sort out issues.

Also......picked up nothing from the Monoblade so far over a 58mm tb so far.

Once the car is dynoed please post the results just to see if there is any difference. Usually Dynojets are pretty consistent unless the operator is playing dyno games.
