Dyno Charts Have Been Added
I recently went thru an upgrade of my stock exhaust to a set of Vance and Hines Straghtshots and had a stage 1 jet kit installed. The following are the dyno results.
Keep in mind that the baseline numbers are a tad bit off because it was run with the new pipes not the stock pipes. Also, i have not yet put in the K&N air filter, I'm awaiting the big brown truck before I can. I was told I could expect these numbers to increase slightly with better air flow in. HP I was told shoud increase 1 to 1.5 HP. Not sure about the torque number.
HP before 48.16 hp
after 51.88 hp
Net change 4.63 hp or 9.6% increase
Torque Before 60.07
After 67.87
Net Change 7.66 or 12.75% increase
The numbers themselves don't tell the full story. The torque curve is most impressive. Where the baseline curve goes up slow and eventually max's out at 60.07, the new curve shoots straight up to 60 or so and where it begins to level off to its full potential it is already12 ft. lbs ahead. If I can get the numbers scanned, I will include the charts here too.
