thottle control

have a co2 thottle control for staging car;;never used one so it's all greek to me as to how it exacly works;;i understand that i can adjust it to say hold butterflies at certain opening and can hold pedel to floor but butterflies only open to what have adjusted to;when release trans brake then air slams butterflies wide open;;
now what i'm wondering is if i don't turn on co2 bottle while i'm doing my burn out will my butterflies only open to where i have them adjusted for staging?why asking is trying to see if someway i can use same system to control my burnout rpm also;;since new to all this and having never drove car i'm concern that i'll have a habit to try do full thottle burn outs as use to do with street/strip door cars..i understand that is a no-no with a blown/alcohol car so don't want to damage car.

 

I was thinking about this also. Except I would use a switch to deactivate the cylinder in the burnout.

 

throttle

yes you will be able to open to your pre-set.
if you put a on/off switch between trans brake. you can just press the throttle control button during the burn out.

 

so leaving co2 bottle off [so no air to thottle control]then i can floor my pedel but thottle blades only open to my preset opening i use for staging car;;correct???OR do i have to us a on/off switch between trans brake??

 

Yes to question. No co2 from closed bottle, means no air to cylinder same as dumping pressure with switch, only goes to preset opening. But... I highly doubt you will be able to do a burnout with the minimal throttle opening. The problem isn't really lack of "power" with reduced throttle, it's about impossible to "whack the throttle" to get wheel speed up quick and then pull back to a minimum throttle to maintain a good rolling burnout. You can sure try it but all the ones I've set up, have driver whack throttle in high after rolling through water and then let off to maintain a comfortable rpm. You'll pick it up quick plus every track seems to wet the water box differently, if you go to smaller local tracks that are not used to rolling burnouts, a lot of time they don't put down enough water and you'll need the ability to get after throttle to get you're burnout.

 

very good point John..never thought of that..sure sounded good on paper when i thought of it..lol..guess just going have to trust myself not to get carried away on the thottle then..i was thinking a few times to do away with the thottle control and just do a simple cable hook up and get the thottle stop that good vibrations sells sells that pins onto cable for the burn outs and pit crew removes before staging;;trying to figure best safest way;;being my first blown car got lot to learn;

 

I hear ya. When I made my first passes ('93) in our first blown door car, we tried all kinds of stuff to limit burnout and be consistent including the throttle stop that pins on. After my "crew" forgot to pull it off after burnout the first day, it's been laying in my tool box for damn near twenty years, lol. Really, just take your time, keep it simple, you'll pick it up quick. Good luck
