What's your RPM at 70mph in 5th gear with the 4.44s, if you don't mind me asking?

Do you know what it'll be with 4.78s?

Siraniko 07-11-06 10:47 AM

above 5K. RPM was dropping as I let off the gas to take pix during the rotary fest caravan. Keep in mind that I used 46 venturies in the 48 IDA. Otherwise, I would be cruisng @ 5500 at 85 mph.

How have you corrected the speedo?

yes except I let off the gas so I can take that picture. It was after Doc and I were hitting around 140. How do I know its accurate? My bro (GSL-SE) and I drove side by side on prior run to confirm that my speedo is correct.
