Jeffko, Straight axle does dominate drag racing (primarily due to KISS design and ruggedness), but I know of many IRS cars in the 9s, so until we're talking about 9s, I do not think there is the difference in performance (maybe breakage) that is purported. When our cars are running 9s, then we can have the IRS is no good for drags debate...

I suppose there are many things to consider as well as ways to put things into perspective.
As to drive line endurance I have most always started from a bit above idle to be easy on the drive line, but once tried to launch from about 3000 rpm with the Superformance half shafts. The inner splines, driver side shattered with in the differential. I picked up stronger complete half shaft assemblies from
The Drive Shaft Shop, but don't intend to launch the car again. Well, I'll try not to.
The Drive Shaft Shop did say the new parts would stay together none the less.
The trap speed and
DA (density altitude) pretty much tells the story of what a car could do relative to sea level if it hooked and the drive line didn't blow apart on hard launch. In my view I don't really want to thrash the car to get a time, so I just theoretically apply a bunch of coulda what ifs. You won't break parts that way. Theoretically same DA(2100-2200ft) and HP for my pass above with all together drive line hard launch would be a 10.55 if a
drag racing calculatorwas used to estimate working off trap speed HP. If the time and speed is evaluated in perspective to
sea level corrected It's a 10.28 @132 mph.
Time and speed corrected to sea level, and with the addition of 42 HP and perfect hard launch run(wet shot NOS and solid engine mounts tempting to install), the car has potential for a 9.99 @ 136.5 . The problem there's always another guy's car that's faster.
I know, I think way too much and have too many dreams.
