Freestyle ignition curves

[Superjet3]

Well I have the new WAX ignition and I would liek to play around with some ignition curves.. I have a few I have tried but I was jsut wondering what everyone else is running.
Here is what I have motor wise.
701 62t cases
61x cyl stock porting
180psi comp
Factory b pipe with mod chamber
V-force reeds
spacer plate
riva intake
Dual 44mm taper bore NOVI’s.
prok filters
MSD coil.
Solas concord 13/16 3mm cut back.

Paul can you tell me what rpm your ski is getting at the moment up top
Also what jets are in your carbs
as if you are slightly rich you can bange a couple more degrees in it and get it to hit harder down low

 

[Superjet3]

Wax,
Havent had a chance to get a tach on it yet. I guess I could play with lowering the rev limiter until it starts hitting it. I have it set to 8200 rpm and Im not hitting that.
I have dual 44 novis with a 2.0 n/s 85g spring @ 22 psi popoff
Low screw 3/4 out
125 low jet
115main
1 3/4 out on high screw

ok and you are using the curve i emailed you

 

[Superjet3]

Yes.

 

[Idok]

man, with that setup you need some PORTING!!!!!!!!!!!!

 

[waxhead]

Yeah a good port job would be a great thing

Suprisingly the thing rips as it is... However, I am in the works of building my 5mil lamey powervalve motor.

Are you on race gas? If not, be careful. That's a fair amount of timing around 7000.

[Superjet3]

NO I am not running race gas. 93 octane. Maybe I will bump it down a tad then.

 

[waxhead]

wow thats an interesting curve
i would like to see it at about 17-18 on a b-pipe at 7000 rpm

 

[SUPERJET-113]

Thats cool Wax... someday someday!

 

[waxhead]

yeah maybe if i sold more ignitions i could do it
I was going to try and put it together with my type 9
v force reeds
light weight fly wheel and 48 novis
i have everything ready to go except the light weight flywheel
the ski has a 12 vien i was hoping for something like 64 mph to scare the c@#p out of me

Darren Hedlund mentioned either in a chat or a post on pwctoday that on Yamahas he always ended up around 15-16 degrees final timing.

Here is the curve i run in my type 9 race boat
its work very well
i still want to play with more advance down low but other than that it pulls hard
the boat will pull 7600rpm
