Not that I care, the car has run the number....

But I am curious now to see how much of a diff there is.

edit. you ran 124 with 469rwhp, not the 481.

Spellbound

Correct.

There is some video, but it's shot from the end of the track and it shows my girlfriend kicking my ***, LOL

I will definately have some for the n2o run. With the way the weather is here it looks like at least a week from this Saturday.

exactly....aren't most dyno pulls done from forth gear, or taken to the closest 1:1 ratio????

You could always dyno it in first gear and be really impressed with numbers, RIGHT????

waSStock

Actually, you are both wrong. A real dynamometer has user entered inertial compensation for the engine/drivetrain. This dramatic difference in HP vs. gear selected is just one of the short falls of DJet software.

J-Rod

Yes, you'd be extremely unimpressed. Dyno in 5th or 6th and you look alike a super-hero... Lower gears dyno lower... Higher gears dyno higher.

you are kidding , right?

an accelerometer with a good guess at engine RPM?

Ok, we had some decent weather so I was able to get an appointment today for some pulls on a dyno jet....
The differences between this run and my last runs were about 10 gallons of 100 octane on top of about 4 gallons of 91. A/F was done at the tail pipe instead of the o2 bung on the collector.

I had them do a 3rd gear pull also which is in red.

For those who may think I am unhappy, I am not...the car runs good at the track!

so the 455/409 runs were in 4th gear? how did the car go from 481rwhp down to 455? was this the same dyno that you dyno'd 481 at?

Spellbound

This was a completely different dyno, a dynojet, the two 455 runs were done in fourth, the run in red was in third gear. The other numbers were prolly close to uncorrected or std.

I dynoed 427 on Synergy's Dyno Dynamics. Three months later after injectors, ported throttle body and tuning for the changes I dynoed 407 on a dynojet.

They actually have a dynapack 4000. I typically see lower numbers than thiers on my dynojet, but who really cares, its more about the gain I suppose, but it is nice to be able to compare and know where you stand, the dynojet has been reputable in this department for me.

Don, does FFP's dyno do SAE correction factoring at all? that is something I never see mentioned, if you will look at your numbers they are corrected 3% down, which would be 469 uncorrected, which is still not 481, but what was the weather like that day? If it was really cold the day you did 481, I could see a 10-11 hp swing. either way your car runs, that is what really matters

Great #'s man & thanks for pulling 3rd & 4th gears on the dyno to clear things here

Your right Nick. My baseline dyno was done by Keith on a dyno dynamics. Those numbers were lousy. Rick's dyno numbers were high. I think he had just bought the dynopac.

If you look at the column graph the air temp on the 48x pull it was 57.9 *
