Interesting regarding the no lsd. Sub 11 sec is very fast.
Usually real dragracers have a solid rear axle. they call it a spool diff but its a lightweight straight lock. Either that or clutch plate (salisbury/ramp style, not speed differential like an M diff).
The thing is that there is no such thing as equal grip. there is always one wheel with more grip than the other, so if you have the power, locking up the rear is always the best thing. And as you're going just in a straight line, there is no need for different rotational speeds, so diffs that lock up are best.
But obviously getting the best tyres is the most important thing, because in the end its the traction (grip between tyre and road) that gets you going...
Who knows what time he can put down with an lsd or spool (but that would ruin his road capabilities

)I had a go at this at Santa Pod yesterday. Never been before and I went as a bit of laugh with an old mate who's just bought an M135i Auto. I did three runs in all, with mechanical sympathy at the forefront of my mind off the line, but even so I was rubbish getting the car away cleanly, and my reaction times were rubbish on the first two. My best 60ft time was 2.47s and my best 330ft was 6.23 so it shows you how slow I was getting away. Nevertheless, I did manage 13.8 at 106.92 mph which wasn't bad. My mate beat me on all three runs but it was all down to him getting away cleaner and the auto was a big advantage too. He did a 13.4 at 107mph. I was catching him up on 2 of the three runs though so if it had been a standing km or 1/2 mile I reckon I would've done him, even with the crap starts.
We saw what was reputedly the fastest road legal Nissan GTR in the UK record an 8.5 at 171mph and that was with him giving the heavily modded Civic he was up against a deliberate head start. It went off like a scolded cat, it was incredible. It must have been very low 2's to 60mph and probably high 3's or low 4's to 100mph.
