I got my truck Dyno'd. It did what I expected and I am very happy with the results. Please keep in mind im rolling on 35" tires and im a 4x4. The tires caused the "low" numbers and the graph to be wavy the way it was (did not do to much smoothing). Everyone in the dyno bay was kind of scared to be in there while I was dyno'ing At the top of third gear the dyno read I was doing 160mph lol

If was on stock tires the numbers would have probably been over 300/300. Next I am doing some small mods hoping to reach over 280 hp and over 300 ft/lbs. Under drive pulley and ported TB any other suggestions?


combo:

XR265HR 212/218, .522/.529, 114LSA, Pacesetter LT's & ORY, Intake, Gibson catback. Custom tuned by me with the help the mods of hptuners message board, 12secSS, and my buddy.

notice the torque curve

272hp, 295tq

 

Excellent results! AFR is dead on! Did you have time to play with the timing, that is all I need to do with my truck to extract more power out of it. It might not be much, 5hp about. Either way, great results, I love the flat torque curve from 3200-5200 rpms.

 

Not bad for $120 cam shaft and free ls6 springs huh?

Timing was 28* total at WOT.

I was hoping for 280hp+ and 300Tq+. What little modifications do you recommend to get there? I was thinking under drive pulley and ported Tb. What else do you think?

 

Good numbers! I'm surprised you didn't throw a driveshaft...

 

160mph on 35s, with stock driveshaft , no thanks

 

I have mad driveshaft skills.

 

congrats!
the rollers don't care what size tires you're on so they don't matter
pull it in 2nd next time- 3rd is ridiculous- it'll show like 160mph which aint real

damn good lookin truck!

 

Looks good

 

2nd? 0rly?

 

Yup, second. See all that crazy vibration in your graph? Your tires and driveline are being waaayyy over rev'd and shaking while you're pulling. You're seriously lucky you didn't lose your driveshaft.
