SRX 780 clutching for top end?

[77-SRX]

Any suggestions on clutching an SRX BB for big top end? Hope to hit 120+ in a long lake run. Using 8bu00 now which go like hell in a drag race but run out of steam around 110mph. Thanks in advance....

8DN-10's or 20's with a lot of tip weight

8bu-oo will get good top end. You need a helix with a low finish angle, lots of tip weight & a green secondary spring at about 80 degree wrap.

Thanks for your replies, Guess I'll load up the tips on both those sets of weights and give it a shot.
