few questions I am building a second motor to run pro star s/c. Right now I am leaning towards putting some spray to it to be able to dial it in at 8.90.
My question is, what size should I make the motor to start with using a stock head that is ported, what cams to use(just figured I would ask,not expecting a response to that one), and what is the best set up for valve seats etc with nos.
BTW: Kawasaki KZ 1000 motor
Spend the $ on head work, NOS is a pain in the ass for brackets, top gas maybe but not S/C.
Just my $.02
JSK, Everyone has theirowncombinations. ButI like to keep it simple=cubic inch and compression.I run a 1428 with 13.5:1 wiseco pistons, Z9-Z10 cams, head ported with the biggest valves you can put on stock seats, 40 Lectrons. I agree with Danno, have torn up too many parts with nitrous. A lighter rider could get by with less.[img]smileys/smiley2.gif[/img]

As you can probably guess my motor is almost the same spec (Or soon will be) and i'm intrested to know what kind of times to expect.
Rich, 1.30 60f- 3.70 330f- 5.70 660f - 124mph bike 380lbs me 250lbs. Cams or Cam Motion z-9 z-10 465lift and 485lift. The only 1/4 miles time I have was without gone into5 gear an run 9.48, have not ran 1/4 since I fix tran.
1327cc, 14:1 CR, #109 webcams, GPz head with stock valves and S/S port job...8.60@150mph...plenty for S/C...
stock motor with a set of studs and valve springs, and a ray-jay ef60 turbo.
I runa NO2combo in S/C. I like the idea ofhaving adjustable horse power to run the number where ever I go. It requires more work. You need to fill bottles all the time , deal with the temperature and pressure fall-offs and the need for better electronics. It is NOT cheaper.It's just what I prefer at this moment. I also need all the HP I can get because bike and rider is at 720Lbs. I run 1428 13.5-1 with 480/465 cams, 38.5/31 Z-1 head,40 Lectrons , 1-2 GpZ auto and car tire. ( with button start).
I estimate I would need 1500 motor with Ward or Killer GpZ head and big 500+ cams. 44 trons, to make it on all motor and be able to run 8.70's. (250hp)
With that said If I could it on all motor and a throttle stop I would prefer it.Just run and gun with little or no maintenance
CNC dude, that is pretty much my idea with the nitrous, adjustable horsepower. I was also wondering though, what is the smallest shot I can put to a motor.
Lets say I have a motor that goes 9.00-9.05 on motor all day long. Is it possible to make that system give a small enough shot to take it to 8.90.
Put a 40 horse shot on a timer- spray it at 8 seconds into the run or so...
