Jed,

I think you and I are saying the same thing here, but its good to get a different perspective. I always recomend 4 pts of octane higher than your piston recomends. So, you octane will naturally be higher for higher piston compressions. However, what throws a wrench into the mix is, as you said, the CDI box. N20 does not like advanced timing CDIs. What is does is narrow your window of "safe" nitrous with regards to the danger of pre-ignition. I have not heard of any problems with the Vortex because I believe its not that advanced. But I can tell you that I have had problems with my one of my CDI's I use on my EX.

As blackhawk pointed out, we like to run advance timing on our quads under normal riding conditions, but when running N20, especially at levels above 25hp or more, you want to retard the timing if possible. The Vortex is a great way to do that.

I currently run my stock CDI on my ex, but am saving up for the Vortex.

 

Most aftermarket cdi's offer up to +7 over the stock maximum of +25. As I recall the Vortex, Procom, Ron Wood are all +7 at peak advance. Now the curve coming on earlier in the rpm range where there is more load (slower moving bike weighs more to the engine) might make a difference.

If you guys were running the same plug temperature, carb settings, compression and fuel and the cdi was the only difference, you must be right on the edge of what you can handle........unless you were running the N2O timing curve available with the Vortex which includes lower advance settings and possibly a couple degrees of retard at the top of the rpm range.........

Hmmmm......

 

Nut, ya I dont know the numbers. I tried a Ron Woods setup on my bike, no nitrous and it wouldnt run, just spit and sputtered like she was lean.
And of course we run it on the edge, is there any other way?[img]i/expressions/face-icon-small-happy.gif[/img]

 

Got a chance to do a bit of research on the weekend regarding boss noss, found there website and there is a lot of good reading and pics for those that have not seen it before. I just typed in Boss Noss in google and went to there website, I think it was bossseat.com ?

Marky, previously you mentioned the tank required drilling, I notice on the website they say just to tee into the fuel line to the carb for the fuel dump, is there a reason that can not be done on the DS?

I will be fitting the 60% clutch springs.

The website is out of date, all ATV kits require a separate fuel line to the tank. This change was to make sure there was never a fuel starvation issue to the carb.

 

marky wheres my stupid magazine at ? i need something to read

 

Do you mean catalog? Want me to send ya one?

 

yes and yes thankyou

 

The web guy has a way to request them at this address: http://www.bossseats.com/Catalog/index.asp
