Hello people!! Been a busy weekend for us...we went and "dyno'd" the engine this weekend to make sure it didn't get wounded in the carnage we had a few weeks ago that took ou the rearend, the driveshaft, and the transmission......and to see how much HorsePower we were making and figure out some tuning decisions. Here's the rundown:
570 Hp and 486 Tq.....
Now I was hoping for 600 horses but it was still enough to run in the 10.30's at just over 130 mph this season, so I guess it is was it is. We should have used a less octane fuel for my compression ratio and the guy running the dyno says that could have affected the outcome. We have the engine up at the machine shop (Midnight Maching) where we'll have the heads milled a touch to gain some compression/power for next season. My goal with this combo is still to run in the 10's but I'd like to be in the 10 teens to 10 twenty's instead of the 10.30 to 10.50 range....after that we'll get REAL aggresive with the camshaft again. We're still running a CompCans Extreme Street grind cam in this combo. It was fun and we learned alot!! The timing affects this combo WAY more than jets did (varying the timing by four degrees either way kills the power and torque) and running it warmer than normal KILLS the power too...If we're on a greasy track we can keep the launch working well by dropping the launch rpm down to the low 4000 range where the torque is slightly less that the high 4000 to low 5000 range we normally launch at. Running the engine on the dyno reaffirmed alot of things we thought we new about the car/combo...Now if only all the other stuff wasn't in pieces we'd be set!! Thanks for all the help and support here folks!!!!!!! Gene
