SS #670 Dyno

SS #670 Dyno

I took SS #670 to Terry at the Dyno Room located in the Mustang Ranch in Santa Clara to get some baseline measurements of my car. He has a Dynojet 248C.

Corrected	Actual

308.8 HP / 321.6 ft-lbs	320.5 HP / 333.8 ft-lbs

These runs were made at 4955 miles with a stock engine, intake and SLP dual-dual SS exhaust. I ran with Mobil 1 5W-30 synthetic oil and on Union 76 92 octane fuel.

The graphs show my final two runs which were made after we started using a fan to push air past the radiator. I captured the water temperature numbers with Autotap; the 25° F increase in temperature appears to equate to loss of 4 HP between my two best pulls.

Here are the stats for the two pulls:
