With the NX and the Holley, that is exactly what happens when the system is not regulated. Gary did a good job of telling you how to work that system. And I give you credit for acting on that. But you know, Gary will be the first to tell you that it scares the heck out of him to put those systems on most customer motors - because those systems change so much depending on pressure - which is affected by bottle volume & outside temperature. Most customers get complacent, and then squeek a cylinder. That doesnt do the builder or the customer any good.

 

hey i just like the joy of working on the machine reminds me of 2 stroke days[img]i/expressions/face-icon-small-smile.gif[/img]

 

This is the type of situation I worry about and have heard several horror stories of.

Sorry to pick on you Major, lol. I didn't realize you were the precedent on both sides of this discussion, lol.

It is all good because we are all learning! [img]i/expressions/face-icon-small-smile.gif[/img][img]i/expressions/face-icon-small-smile.gif[/img]

 

This is not a nitrous problem. You overrev any motor to vavle float you will have problems. I mean if he had a tm45 on should we blame it on that or the LTE exhaust. NO. You rev a motor out of the range the springs can handle and you will know it NA, nitrous, or supercharged. Next we will have to put warnings on aftermarket cams and light pistons because it makes the engine rev faster if you miss a shift with no rev limiter blame it on the piston and cam grinder.

 

Given the human reaction time, if you are WOT and at the top of the rev range and the tranny pops out of gear, the chances of floating the valves is much greater on NOS than without. You will be at a higher rpm when you realize something is wrong and back off.

Sorry, bud. I'm not changing my mind here. [img]i/expressions/face-icon-small-smile.gif[/img]

 

What is the rev time of a motor under a load at shiftpoint to overrev when its kicked out of gear ? Anything more then .400 i don't think any human can react that fast nitrous or not.

 

This is may be the best reason I have heard to not buy a Woods CDI.......for Nitrous or Motor applications. Always run a rev limiter[img]i/expressions/face-icon-small-wink.gif[/img][img]i/expressions/face-icon-small-smile.gif[/img]

 

I agree if your going to race engines with modified stock parts in them. Your using them far beyond there intended limits.

 

interesting

 

Sorry, rcoop. I missed your post on this one. I didn't mean to ignore it......

Do you think the N/A motor will hit the point of valve floatation with as great of force as it does on the button???[img]i/expressions/face-icon-small-wink.gif[/img][img]i/expressions/face-icon-small-smile.gif[/img] Are you as likely to pop out of gear with the force applied to the dogs N/A as you are with a 30 shot???

A revlimiter is important to have, if you don't think it is even riskier running without one while pushing NOS, that is ok.
