first 408 dyno report

q trim .96 ar.
there are lots of things for me to try. the new header/downpipe will have a 3.5" downpipe. my next mod will probably be tires so that will help on the dyno numbers too.
before any of that i think i will go make a couple of runs on a dynojet just to see what it says.

here are some interesting numbers. when i went to kc on the dynojet the max maf freq i saw was about 12700 at 16psi on the 6.0. today i saw a max of about 12800 at 14psi. that sugests i am making more power at 14psi than i was at 16psi before. it sure feels that way and would make sence.
then, some creative math based on that freq sugests i am around 76lb's of air. 76lb's x 10hp per lb = 760 fwhp x .8 = 608rwhp.
all these numbers and my seat of the pants dyno sure make it look like that 519hp number isn't correct.
i am told the track in kc is open weekends in about a month if it is nice. thats not too far away. i hope to be there.

Keep in mind that you cant compare numbers from a dynojet to a mustang dyno. You can have as much as a 15% difference. Add 15% to your 519 and you almost get 600 or so. Something to think about.

here is one of my other charts overlayed on the one decent looking 408chart. you can see some nice tq numbers coming on before the wheel slip kicks in.

i think the only run that was correct at all was the very 1st part of the 13psi run. it was looking prety good there.
i am going to go put in a gtech run today. i found out the local dyno jet is geting moved to a new location so it wont be running for a few weeks .

I think you are correct on the wheel slip. Like I said, a set of sticky tires can help but I forgot to mention, due to being so late at night, that you might want to load the back of the bed with sand bags or cinder blocks. I know up here in the snow with the measly stock 6.0l hp I slip slide around in the rain or snow without any load in the back.
Like you said, new tires, at this point, would probably help quite a bit. It is easily seen by the numbers you are initially producing. You are making GOBS of torque!
