I think his 1/8 et and 60'' are quiet good considering the mph. Nothing to be sneezed at for a heavy 4x4. No doubt the sticky track helps a lot here.
Just needs more horsepower for the second half of the track to really get it going. Where does it end though?
At some point you need to ask yourself if you are building a pure drag car... or a tough streeter. The more you start digging in to the engine to find those neddies for the track, the more drivability suffers on those nice Sunday drives.
It's quick enough now to beat almost any normal car off the lights...(except for my lux,lol)
How far are you going to go with this car?
Unfortunately, I think to get much more out of it in the top end of the track, your going to need more hp, either nitrous and a separate fuel system or bigger injectors, lower comp forged pistons, some head and cam work, and more boost.
That's when the rest of the car starts falling off.... Some days I wish i still had the old 2.8 diesel under the hood and then others I wish I had a nitrous fed blown big block.
