Hehe, just yanking your chain there Knutz.

 

No Worries

 

I can assure that the Custom X pipe was on way before the CDI unit from Team Pami. The instrument pack is something that I made up from a couple of Datel LED panel meters, a sensortech pressure transducer and an AD656 temperature transducer.

It gives good accurate readings, better than a light on the dash.

how does the Pami box compare to the Woods box w/out rev limit? is the timing curve the same?

 

I have not had the opportunity to see the actual mapping chart of the Ron Woods ignition box.

 

Knutz,

xray's post seems to imply that the CDI box does add performance in various areas. I recall in another thread that you stated using a box with even an 8500 RPM limit it would be advisable to change up to heavier valve springs. Does this still seem to hold true or what would you say the requirement for the 8500 - unlimited CDI box is.

Also, what is the difference in the curve that the CDI box provides? Does this change then require race fuel? I think for myself and many others, the cost of race fuel is very inhibitive.

 

The specifications of the cam shaft determine were in the rev range a motor makes it's power[as a general rule]. The ignition box recurves the timing to help make the most of the power within the parameters of the mechanics of the motor. To use the motor outside of the rev range is possible with a raised or eliminated rev limiter, but not recomended unless other steps have been taken to make power at a different rev range. If you use the motor in the recomended rev range[or slightly above]there is not a need to change valve springs. If you wish to run the motor to the rev limiter on a constant basis, I do recomend a stronger valve spring. Just because the limiter is raised or eliminated, does not mean the motor should be revved as high as possible without making other changes in the motor.

Just as another ignition box has been described, ours advances the curve in the lower range and eliminates the retard in timing that restricts upper RPM use.

An ignition box would not require the use of race fuel. I don't believe that I ever said our box required race fuel. When I first started bringing these motors to the U.S. the compresion ratio [12:1] did require race fuel, but due to the interest in a lower compresion ratio piston for the use of pump gas, we now carry 11.2:1 ratio pistons.

 

Thanks, that makes sense. No, you never said that your rev box needed race fuel, I just wanted to clarify that (some other companies just assume this sort of thing.) I do recall you mentioning that the compression was changed from 12:1 to 11.2:1 to allow the use of pump gas, which makes owning a high performance machine easier on the wallet. This is the kind of attention to customer choices that every company should display. Whoever wants to run race gas on the 12:1 piston can, and those who don't want to, can still get what they want and run pump gas, choices are great. Thanks for good info and quick responses.

 

Xray, what kidn of power gains were there? I'm really thinking about buying a cdi from pami. Can you tell there is an extra 1400 rpm to rev or does it just rev out as quick as stock? What about the differnce in the "feel"? Thanks alot

Count me in. I'll have a money order in the mail, priority, on Monday. Nobody has the raised limiter CDI, and Knutz has the best price. Ahhh, electronically unimpeded jet runs....[img]i/expressions/face-icon-small-cool.gif[/img]Count me in.
