Dyno session scheduled for tomorrow. (This should get some people's attention.) Race the following day on the 7th.

You think? Looking forward to the results!

Me too. I haven't done any changes to the tuning yet. I know what to expect. Loss of torque <3000 RPM, lots of HP 3000-5500 RPM. I also want to discuss with these guys about the injector voltages to see what the know about the stock Mustang injectors I'm using. I think that will affect my daily drivability more than my WOT performance though. I do plan on adding back some timing <3000rpm though. I'm also curious to my actual vs. dialed-in a/f ratio to see how much more I can push it to ~13:1 ... So post-dyno, I will do some tuning...and eventually another dyno.

Shitty and fragged up. I'll post sometime this week. I have a best of 149 hp and 167 torque which makes no sense and my fuel curve was whacked. Also didn't get to cool my motor, got there and dyno'd it right away. I also lost in the first round to a car I've beaten before due to bogging the launch...I think I need to go back to 16's ...

Post the dyno sheet, I'd like to see your A/F also.

I'll try to take it to work and scan it. What is standard temperature? I think it was 95 and really humid when I went at 11:30am. I don't know if he was showing me corrected or uncorrected #'s but he claimed to be 13% below dynojet dynos. When he showed me 149 the other value was 162.5 and I was confused as to which was which. The first Mustang dyno I went to several years ago was specifically calibrated to Dynojet specs.

I scanned it to PDF. Perhaps tomorrow I'll screen copy the pdf pages as images and upload them.
This dyno shop is definitely not all there. Says I made about 167 ft*lbs of torque. That's about what a 2.8 makes. I think he somehow managed to scale down my power via certain parameters he put in. Even the most basic of 3.4 swaps makes about 200 ft*lbs. This dyno is basically saying I am making 20% less torque than the most basic of 3.4 swaps. This dyno run was bogus. Perhaps he was trying to let me pay him to "tune it"...
Here's me racing a 200hp turbo MX-3 that weighs 2400 lbs with the driver in it according to him. You can really see my launch stumble here that's been holding me back.
I think my oversized wheels are hurting my launches and overall acceleration.
Anyway, there is no way a car weighing 2400 lbs with 200Hp is barely edging a car weighing 2900 lbs with 149 hp. Some simple crtoss multiplication and I should be making well over 200hp myself.

So when will you be taking it to a real dyno to answer all the doubters? Can you take it back to the orignal shop where your other numbers came from, to do a true comparison?

The shop I wanted to take it to was backed up 2 weeks. I'll try again this Saturday.
Looking forward to the results!
