i was up at island dragway in nj last night for test and tune and ran a best time of 10.89 @ 132 on my 99 996sps. mods are full arrow exhaust, pistal high comp pistons and a few others. i was pretty consistent 11.00's but was having a hard time keeping the front end on the ground in 1st and 2nd gear. next time i am going to strap the front end down for better launches. here some numbers. i guess they are pretty typical, maybe even slower than average but its my first time running this bike.

60' 1.957
330 4.953
1/8 7.234
mph 108.00
1000 9.196
1/4 10.890
mph 132.41

Any idea what kind of HP you have with the engine mods?

it dyno'd at 128.8whp

I think that's good for high 9's...

factory gives a HP number of 124HP at the crank so thats pretty good for rear WHP!!

I´m guessing that your dyno is very conservative. 1/4 in 10.89 is respectable.. Especially givven that the dryclutch isn´t exactly made for quick starts. What gearing where you running? Any pics?
Thanks for the info! Now i know what i should expect of mine..

This is my SPS that only has its cams retimed and a mapping.
EDIT: Blue is stock and red is retimed cams 109/109 centerlines and a remapping by Hypertrick. 50mm Termignoniexhaust is the only other engine mod

I did not realize those made that much torque!

They don't. His dyno is reading Newton-meters. If converted to ft-lbs....

1 newton meter = 0.737562149 foot pounds

He's making about 75 ft-lbs of torque.

M90, your times are actually very good. Your ET/mph is excellent for what you got.

Your focus, is that 60 foot. You want to try and get down into the low 1.7's, high 1.6's if you can. A strap (try the universal once from Schnitz Racing) would definately help.

Dry clutches do NOT like to be slipped, so you're just going to have to drop it at a low rpm (start around 4k) and nail that throttle. The idea, is that you want to be WOT *before* you pass the tree.

Times are very good, I like to see people drag race Ducs (I've drag-raced Hayabusa's for 8 years). Will eventually take mine down there to see what it can do.

Whoops!

Almost identical power to my 999S with half system, ECU, filters and dyno map.

thanks! i am 150lbs soaking wet so that explains the bad 60' w/ high trap speed. i was having real issues w/ the front end in the air until about 60mph. next time i hit the track i am strapping this thing down in the front 2-3 inches and see if that helps. a 1.7 60' should bring me close to 10.5...

on a side note my trap speed was almost identical in all 5 runs. it was between 131.5 and 132.5 every time.

i dont think to many 128hp bikes are hitting 9's...

Nope...just the perfect drag bike with the perfect ET. Just calculated, that's all.

That's about what my 996 makes with similar engine mods. You might get more with tweaks and other mods, but pretty soon you've built a grenade.
