With temperatures having settled down a bit, I scheduled some dyno time on AutoTalent's dynapack in Carson, CA. I know a lot of members here have run their cars on dynojets, and a lot of numbers have been published from that machine but I don't think I've seen any results from a dynapack yet.

Anyhow, here it is. Modifications include the 168mm pulley / Kleemann headers / AMG TB (80mm). The rest of the mods can be found in my signature. Car has a base tune from Kleemann and was running 91 octane pump gas.

I do have a "before" dyno on a dynojet. It's on another drive so I will add that here when I find it.

Air temperature was ~ 70F

Did not log IAT's, but I do have a AFR meter. At WOT the car was running 10.5.

A second run resulted in a higher tq figure: 534tq vs 528tq, but the hp was down slightly (446hp)

EDIT: I have added my dyno from OETuning's Dyno Dynamics Dyno of my car taken about 2 years ago. Running 91 pump gas and having performed no modifications at all.

TL;DR:

Stock: (avg of the two runs): 327.15hp/377.35tq
With Kleemann mods: (avg of the two runs): 450.8hp/531.8tq

Difference: 123.65hp/154.45tq

Again, as stated below, the two dyno readings have a variance in the way they read the power (also--calibrations) so take that into consideration when reading the numbers. Thanks.

How much does a dyno session run and was it a pleasant experience at the Carson facility?

Toadster

you're putting down the same HP (446) that I logged with my S/C pulley & Tune on a Dynojet - but torque is > than mine at 487

What do stock E55's put down on that same dyno?

AMG E Power

Wow that's super low for those mods. A Member on this forum with kleeman pulley and headers put down over 480 HP and his TQ was over 600 on dyno jet.
He's the one with the bad a$$ alpha gt-r, maybe he will chime in

Diff dynos will give diff readings, but you can go to an AFR of 11.0

TheOtherDodge

Agree with above. 10.5 is way too fat!

@Prada: I paid $100 for three pulls. The tech even waited for the car to cool down a bit between pulls as he saw that the car started to exhibit heatsoak. They were familiar with putting the car into dyno mode (something that I didn't even know had to be done on the MB). The facility is huge as well, so I was very happy. I've been taking my car there to have all my mods as well as maintenance performed as well.

My intentions will be to run the car on a dynojet in a few weeks once the facility that has it available has it back up and running. I think at that point it'll be a good comparison between the two dynos.

u might have a dead pump so log your intake temps and see how they look.The dyno you used reads hi,higher than a dynojet even and your car should of broke 500 on this dyno with your mods.

kleeman tunes for 11.8 top end and you are in the 10s with a dyno that dosnt even use the wheels on the car so it has less load than just spinning the car on a lift.

Just out of curiousity how much difference is there between dynojet #s and mustang dyno #s?

Hulk

5-10%

Nice HP up top, kleeman tunes hold the power nicely on the big end.
