No , not making any excuse's at all.
Both cars were made for Bathurst, both cars in their day were incredibly fast.
One was slightly faster at a certain point when the other one would show it's strengths.
The Charger certainly was potent up to 100mph after that the GTHO would take over. The Chargers top speed at around 6500rpm(1000revs past it's redline) was around 130mph.
A stock GTHO Phase 3 at its recommended redline of 6150rpm(rev limited) would top 141mph. Disconnected some would reach 7500rpm in top or nearly 160mph. They revved them to 6500rpm at Bathurst and 7000rpm on Conrod straight.
The E49 with it's 3.5 diff ratio certainly pulled harder than the GTHO Phase 3 with it's 3.25 diff ratio through the lower gears and up to around the 100mph mark after that it's was the GTHO's domain.
When people think of GTHO peformance times nobody ever talks about the factory diffs that were available.
When you ordered your PHase3 you were asked what you wanted with it.
The following is an extract from an Australian Sports Car World magazine i have from September 1971.
"Another important development in the Phase 3 is the availiblity of of close and wide ratio gearboxes and three diffs -- 3:25, 3:5, and 3:9 to one.(the bathurst cars will run the 3:25 ratio)"
Taken from the same magazine. 1/4 mile for a 1969 GTHO Phase 1. = 14.4
So it matches the E49 Charger.
Unfortunately the only Phase 3's ever tested were all the wide ratio gearbox with the 3:25 diff.
Car's fitted with the 3:5 diff recorded times around the 14 flat and cars fitted with close ratio gearboxes and 3:9 diffs ran mid 13 second quarter miles on street rubber.
I personally know of a stock standard GTHO with close ratio gearbox and a 3:9 diff that runs high 12's to low 13's 1/4 mile times on modern rubber.
Not taking anything away from the E49. It was certainly more than a match at times for the GTHO Phase 3. The GTHO's strength is it was made for one reason and that was to win Bathurst which it did easily in 1971 filling 5 of the first 6 positions and getting a 1 2 3 podium.
The only thing that stopped it 1972 was a wet track and a guy that was arguably the best touring car driver in Australia's history. Not to mention a spin while leading comfortably by John French in the GTHO.
Heres a good read.
