Re: Running on the Dyno with my LS6 on Friday
Hi sorry for the delay...when one plays at the dyno, one pays later on at home and work. Here are the results for my dyno pulls...keep in mind that the car is totally stock, NO HEAD WORK, original exhaust manifolds and stock-type exhaust and mufflers (no resonators) no balance and blue print, with >75K on the motor. Stock carb, no rejetting or optimization. Car is still running points, not HEI or Pertronix. M22. And I've never been to the dyno before. Temp was 96 degrees with 89% humidity. Not a good day to be running a high performance car.
The sound was incredible, it was just amazing to be doing > 90 MPH standing still. [img]/ubbthreads/images/graemlins/shocked.gif[/img] Here are the results of the runs:
Run#1: 305.8 HP, 374 LB Feet of Torque. [img]/ubbthreads/images/graemlins/no.gif[/img]

Run#2: 355 HP, 433 FT/LB of Torque [img]/ubbthreads/images/graemlins/rolleyes.gif[/img]
Go eat lunch, cool car, drink ice coffee, cool car down some more. [img]/ubbthreads/images/graemlins/cool.gif[/img] [img]/ubbthreads/images/graemlins/beers.gif[/img]
Run #3: 356 HP, 515 Ft/LB of torque [img]/ubbthreads/images/graemlins/biggthumpup.gif[/img]
I am happy with these results for now, although I think the car could have done better. I need to do the following:
1. Balance and blueprint the motor. Clearly there was more there. I gave up the ghost at 5500-5700 RPM, and clearly there was more there. Without going over the motor, I couldn't push any harder.
2. Add Pertronix points. No more points bounce and more consistent results.
3. Add 2.5 inch exhaust with 3 chamber flowmasters. Big difference in torque.
4. Carb work.
5. Maybe a multi-angle valve job. Heads are what really makes power.
6. Go back to the dyno on a dry cool day.
I took digital video of the runs and I will post them at a later date (translation: when I figure out how to manipulate the digital camcorder to the computer).
Thanks to everyone for their interest. The Dyno time was the best $70 I ever spent!!
