Wow...that's pretty funny!!! I guess I misread the part in Banshee-Man's post that said it'll work that way on every single bike/motor combo you put it on....not just his own personal experience with his own bike...

 

Oh, my bad...he didn't say that....

 

Since you mentioned the PS drags....why don't you scope out what they're running. The average Joe's will have Dynas...I'd bet on it. The more exotic bikes with ALL the bells and whistles will probably have PVLs....

 

:notworthy:

lol beat me to it... just because i had that big of a gain from my bike dosent mean your going to. i have a realitivly small motor. 4mil with stock bore on fmf fattys... i dought your going to get as big of gain off a 421 but i will say that you will make noticable gains.

Wes and I talked it over and he's gonna let me borrow his dyna for the PS drags next yr. If it does indeed provide the 6 bike gain that you guys say, I should run somewhere in the 3.6 sec range and will no doubt clean house in my class.

 

I guess theres really no point in building a motor any bigger than a 4mil after installing the dyna either, cause I run with most 10mils as it is, so anything short of building a triple will prolly just be pissing in the wind.

 

Can't wait to collect my winnings, thanks for this awesome tip guys!

Nitrous is the lazy mans way of making big hp. I believe it should only be used when you are completely out of options as far as motor and it is being used by every other competitor in your class.

 

I could put nitrous on my bike now and win every local race I enter, but that would only prove that I dont have the resources or patience to build and tune a competitive, normally aspirated motor.

On that, reded...I completely agree 100%.

 

I love watching guys run stock stroke, stock bore OEM Cylinder drag bikes down the track trying to extract every last little bit out, a tenth here, tenth there.

 

Nitrous if fun...don't get me wrong, but....building a naturally aspirated bike that runs well is a thrill as well, and...a lot less to worry about. NOS in the wrong hands can be bad....:)

We're getting off the subject.

 

As far as CDI, I'm running the stocker. I haven't seen any hard proof that spending alot of money on an ignition will improve my times, unless its something exotic i.e. Wilburn or Motec.

 

Likewise for the Nology coil. My brother has one and our motors run identical. It's a toss up as to who will win on any given pass. Mine starts just as easily as his, idles the same as his and throttle response is really no concern of ours. The throttle is wide open from yellow light till the end of the run. Letting off is not an option!

 

I was contemplating the Dave Moore TNT ignition but it is no longer available unless Dave himself is building your motor and he is allowed to tune it. Too many people bought it, installed it and proceeded to go out and burn up their motors, then blamed the ignition.

True Dat.

 

Honestly, I bought my ignition because my stockers were 10 years old. I knew I planned on going alky, and I think you'll agree a good hot spark is necessary to get an alky bike running good.

 

I'm not saying stock components can't deliver that...many still use 'em.

 

However, I wasn't taking any chances. Yeah, I wish I had the $$ for a Wilburn....I don't think you get any better than that.

 

I'm going to get some dyno time in a few months, once my build is done (again) and pull 2 runs on each of the pre-set curves on the dyna, and I'll put my plate at 0 to be fair.

 

Then, I'll spend some time mapping curves, and post those dyno pulls as well....
