ET Streets, and a grippy surface at Santa Pod make the world of difference. Also...actually committing yourself to try and launch hard is a battle in itself.

I usually back down when launching, for fear of breaking traction. Its amazing how much grip some tyres etc can offer though !!!
That pic is almost a WOT 5000rpm launch. I did let off slightly, to maybe 50-65% throttle though. I didnt keep it 100%

By comparison....at Elvington, Woodbridge, or worse Crail or the road. I can hardly touch the accelerator in 1st or 2nd....and for the latter pair 3rd gear also, and thats with 888's

On normal road tyres....1-4 have traction issues on a good dry road lol
