You can't really compare track times to dyno numbers. Especially if you can't drive like me.
Really.

So x amount of weight makes it from A to B at 119 mph. U dont think using acceleration formula u can't figure out hp?

A dyno is a tool for tuning to measure an increase in hp.

Sounds about right to me...

This summer i took my car to two different tracks about a 100miles away from each other, about a month apart. I had a consistent 5mph difference in mph between the two tracks and only dropped about .15... 60's were within .03 of each other. Car didn't feel 5mph faster, that's for sure
Only change i made to the car was adding a little preload to wga and mayb 15-20* cooler outside temps, still high humidity and roughly same Density Altitude correction from what i calculated.

Adding more preload will cause a higher boost spike more than likely. Did you log either passes?

Just saying they are not identical runs. Cooler and more preload could of played a park in higher trap.

I didnt actually log them.. But it was on boost box, same boost map.. Spikes were same.. Potentially could have held a lil better up top in rpms but boost box does a good job of that already.. Just a lil more part throttle response was all I really noticed.. The lesser trap speed was actually less than car did on pump gas but when the car was night and day difference on corn.. I was diasappointed with the mph and honestly thought I had an issue with the car until I went to different track

Like under said, it's not the whp the dyno tells you. All of them are different. Some high, and some low.

What he is saying is, people who DO have the 430whp are trapping 123-124 mph. Driving crappy will effect ET, trap speed generally will be the same.

You've made your point bud. That still doesn't change my numbers. You can argue it all you want. I only posted this to show people what e85 and an ef1 turbo can do. I didn't do this to boast at all, and its too bad that you guys don't believe me. Like I said I'll post my dyno sheet when I can do so.

It does no good to argue with everyone on here. As long as you are happy with your combination, good job. Keep posting your progress.
As far as mph differences, my car dynoed at an x amount of power yet as I was working on my launch/1st gear, I gained 6 mph from my earlier passes to later when I ran 7.96 1/8 ET. (I started in the 8.20's)
I agree with under about the dyno number itself, the number is not so important. It is a tuning tool to show progress/gains in HP on YOUR car. If my number does not seem close or realistic to his or yours, I doesn't matter. If your happy with your result or ET you run then good job.
BTW, when I posted my results previously, I got the same kind of feedback, yet by HP/weight calculation, my car runs what is should.

That sounds about right... I dynoed 401 and my best was 12.1@120 but I couldn't get the launch or 1/2 shift down. My 3/4 shift is also not perfect. All my logs said I lost mph on the 1/2 and 3/4 shift.. I'm sure if I was to hit those shifts my mph would be +3 or +4 at least.

Pretty much why I think this is bs:

Look man. Don't get wrapped up with numbers. This is the reason I haven dynoed.

Cano dyno 540 trapped 132
Zenkat dyno 450ish trap 131.xx

See my point? Don't get wrapped up. We had this same argument with the BWS. People want to see times if times don't match with dyno then something dont add up.

Look, if your happy seeing those numbers on a dyno sheet, so be it. Just saying, a guy with the same "whp" might just walk you like a little puppy taking its first steps. No nitrous, no meth injection. What is left to assume?
