Many thanks, NACW.

Although there are eight 6-letter possibilities, all bar one wouldn't fit 'faster' as they contain either a given letter or a duplicate.

After. Faster minus the F

[emmie]

its def faster...

[Waffoorn]

I have completed the puzzle , answer 20,19,16,23, 6 = aster

[bobbinwales]

wordplay suggested ASTER to me. definition is this flower. Am not as keen on FASTER as speeds up doesnt quite mean faster. IMHO but am often wrong!

[Waffoorn]

Answer is 5 letters not 6. Aster

[Neveracrossword]

I knew it would be F Aster or Aster, so made my answer do both!

[Jackdaw33]

F aster

Aster .. 20,19,16,23,6 and Q is 8. No 6 letter possibilities for faster, leaving the 5 letter to be found. Stay safe.
