When everyone dyno's thier trucks, do you load them up on the dyno? In other words, do you hold the brake some to get the boost up or do most just put it to WOT? :confused013:
Yeah, thats what the normal dyno operator will do, but think about this, if you are on the street, you have more of a load on the truck than you would on the dyno, therefore it would spool faster on the street. At a dyno I went to at Garmons Diesel Performance, the normal dyno guy drove a truck in its first round and it made 495 HP, on its next run, Jeff Garmon drove the truck and loaded it up and it made 608 HP! :blues:Whenever my truck was on the dyno you do nothing more than stand and watch. The dyno operator operates your truck.
But, in answer to part of your question the way they go about it is: run it up in speed gradually shifting to high gear (if auto letting it get to OD) then as they hit the dyno switch they hit the go pedal and after it peaks on the dyno screen they release the dyno switch as they reduce go pedal slowly coasting down.
At least that's what I've observed at the 4 - 5 dyno events I've been to.
Yeah I know that lol Im not dynoing my truck, I just wondered if the numbers everyone posts are loaded or unloaded... :S:with your setup, you arent gonna have to worry about loading it up yourself (holding the brakes)...the guys who hold their brakes are usually those who run big singles, and need to load to get their turbo spooled up...and chances are you WILL NOT be driving your truck on the rollers...just the way it is:confused013:
Yeah I agree with you fully on that! But it will be a while before I dyno my junk :rofyou might be able to grab a little more power out of it, but without a large charger, your numbers should be pretty accurate assuming the dyno is set up correctly. im not very fond of dynos though...they are so hit or miss (operators run differently, varying dyno setups)...comparing numbers between two units is very difficult...numbers are nice, but in the end, how far you pull the sled or how fast you run down the track are true measures of how your truck is running...good luck, post up when you get some numbers:thumbsup:
