Iv'e only got to get some decent rods, 6000 series ferrea valves and some springs and I can start the machine work. may take a while as budget is somewhat family controlled!
This will endup in an XE Spac with C10 4500 stall and 4.88/1 9in for a bit of 1/8th fun
Any HP/TQ predictions and 1/8-1/4 ets?
There isn't enough information to make any sort of reasonable prediction. A lot of important details are left out, including many environmental conditions, tire type and size, vehicle and driver weight, etc...etc.
MPH Gear Tire RPM Slip%
114.7 4.88 26.0 7678 6.0
Est 60 foot ET: ( 37.0 mph) 1.72
Est 1/8 mile ET: ( 93.3 mph) 7.39
Est 1/4 mile ET: (114.7 mph) 11.88
Optimum stall: 5126
Optimum 1/4 mile Gear: 5.06
Optimum 1/8 mile Gear: 6.23
Gross Horsepower (approx): 515.00
Net Horsepower (estimated): 393.60
Based on a calculation of a track at sea level. Altitude density correction would be required. I also estimated an ambient air temperature of 70*F and a relative humidity of 65%, but there are many more variables that need to be considered.
As you can see, 4.88 is not nearly enough gear for an 1/8th mile ride. Get a 6.14 and feel it launch.
