Maybe they'll mandate we have to buy MSD's to go with it.
I suspect the fact that there has been 4 accidents (Radford, LeDuc, Smith and Burgess) at recent events has probably got the NHRA's attention too. I know you could argue that the shut off would not have prevented these accidents but a sanctioning body would not be doing its job if it didn't look into the recent spate of accidents.Maybe they'll mandate we have to buy MSD's to go with it.

this was actuly RB who wanted this one after leDuc's crash he fitted them in all his cars and said there and then he would press the NHRA to make it mandatoryBennettRacing said:
I actually agree with this one. 5.7's at 260mph (ok fastest and quickest) is TAFC speed
this equipment is mandatory in TMFC TMD and TF AFC ect ect in the US its not even used in TF in europe so why would you require it on PM i expect it will be a rule that the powers that be choose to ignore

But again more £££ this is why we have put the TMFC deal on hold, plus we are liking PM ;-)

Just so you know, the electrimotion shut off, ie. the shut off system controlled by the burst panel blowing has be a rule in european TF since the beginning of last year, and is mandatory in FC this year.i expect it will be a rule that the powers that be choose to ignore
The remote device (RF box) is supposed to be in next year but only when the track or speedgroup buy the system.
i do know that
but some teams refuse to fit them as the tracks dont have the transmitters
untill they do they cant enforce the rule for any class,
if speedgroup buy their own what happens at the non fia events when TF and funny car run, easter thunderball ect???
the tracks need to have their own,
its needed at Fia events but not at national events wold be a farce
tf is tf whatever sanctioning body it runs under FIA or MSA

How does the shutoff work when the burst panel blows.
As i read it,It sends a signal to a transmitter located somewhere at the track,which then transmits a signal to the car to shut off the ignition/fuel and pull the chutes.In the rules it says no signals transmitted to cars from the outside,unless they've been changed recently.
It sounds like a can of worms to me,but what do i know...
I can see the merit in the shut offs to be honest, it's better than the knee jerk 100ft racing fuellers have to endure. A remote shuttoff, or device that kills the car and pulls the chutes if the car is under power past a certain point categorically would have saved Scott Kalitta's life. With Pro Mods in the States topping 250mph I can't see why you wouldn't. Yes its money, but its your life and on a £100,000+ car how much of a hit is it really?
hello all,
we have been running the electromotion shutoff system on shockwave since easter this year, there is a plug that straps across the blow out panel on a dragster but on the F/C it is fastened across the deflector shroud that protects the blower belt. if the burst panels lets go the the plug (although not obviously to the eye) is broken this sends a signal to the box provided by electromotion (on the car) which then turns of the ignition and fires two air rams (also from electromtoin) which shut the fuel off and then deploy the chutes. this is not in any way conected to the R/F reciever box, and like what has already been mentioned above, there is not much point in running R/F until the tracks / speedgroup sort out who is going to be controlling this.
i would just like to add that when we first were told we had to use the system we were very dubious about it and had listened to lots of horror stories about aborted runs and chutes deploying for no reason on the start line, however we have had no trouble whatsoever with it, it has fired once when we cough the blower on a 5.80 at the main event. the system without the R/F box is about a $1000 so in reality £1000 by the time you get it back here. i know its another £1000 but on this one i have to say that if you were in trouble at the top end i would much prefer to have it than not.

How???? His explosion occured before 1000ft, which in turn launched the body and deployed the 'chutes. I'm pretty sure that as the crank was hanging out the bottom the engine wasn't really knocking out much grunt either. What part of the automatic shutoff would've saved him? I'm pretty sure no amount of electronics can prevent obstacles in the shutdown area.fgr said:

you are talking about the engine failier part of the system which the NHRA have said is not nessacary in pro mod basicaly as its geared towards blower cars and they dont know yet how to make it shut down turbo and N20 cars Its all burst panel related and although the others have them its not always the first thing to go if in fact it goes at allwe have been running the electromotion shutoff system on shockwave since easter this year, there is a plug that straps across the blow out panel on a dragster but on the F/C it is fastened across the deflector shroud that protects the blower belt. if the burst panels lets go the the plug (although not obviously to the eye) is broken this sends a signal to the box provided by electromotion (on the car) which then turns of the ignition and fires two air rams (also from electromtoin) which shut the fuel off and then deploy the chutes. this is not in any way conected to the R/F reciever box, and like what has already been mentioned above, there is not much point in running R/F until the tracks / speedgroup sort out who is going to be controlling this.

its the rf part of the system that relies on a trackside transmitter that is the problem as no track has one (that i know of)
