Going to schedule a dyno run


Testtube

Recommended Posts

Well i just did a dyno search and to my surprise there is a place located only 5 minutes away from me that has a dyno. Iam going to set a appointment to have the truck do a run.

 

Anyone have any dyno graphs of stock VHO and what i should expect? And also what would be a reasonable price to pay to have the truck dynoed.

I had mine dyno tuned. These are the graphs:

After the PCM tune.

I think it's getting a little more than that now. It had about 850 miles on it when I had this done.

Just a little info on track times. I went and ran one run at the track 10 days after I got the truck on July 27 and ran a 15.562 @ 88.29 MPH with a 60' 2.349. (Also this was the very first time I've ever been so a little inexperienced).

I then went and ran it the same night I got it tuned on Aug 06. 60' was 2.48 (spun a lot more) ran a 15.457 @ 91.22 MPH.

 

Went and ran it again on Sept 7. Made 2 runs this night.

1st run 60' was 2.294 ran a 15.147 @ 91.66 MPH

2nd run 60' was 2.314 ran a 14.946 @ 92.93 MPH

 

I then added a K & N 77 series intake and dumped the exhaust. Went back on April 1 of this year.

1st run 60' was 2.273 ran a 14.721 @ 93.86 MPH

2nd run 60' was 2.312 ran a 14.671 @ 94.35 MPH

3rd run 60' was 2.310 ran a 14.717 @ 93.86 MPH

 

So far it keeps getting quicker as I get more miles on the truck. I'm probably going to run it again here within the next month to see what it will do now.

Your graphs are not accurate. Your numbers could either be really low or really high. On any dyno chart the Hp and Tq lines should cross at 5252 rpm's. The reason for that is motors don't actually make hp, hp is a calculation based off of the torque the motor produces. I'd call the shop you got dyno'd at and tell them they need to recalibrate their dyno.

You are partly right in that HP and Torque should cross at 5250, but his graphs have seperate rules on either side of the grpah for HP and Torque. If they were both on the same scale, then they would cross at 5250, but because the torque measure is more condensed on the graph than the HP, they won't cross at the normal place. If you expanded the torque rule up on the left side so that the 325 mark matched the 325 of the HP on the right, the HP and Troque curves would most likely cross at 5250.
