Throttle stops ?
Discussion
We run a Deadenbear control panel and it is not as easy as a lot of people make it look!
Our car runs 8.50's without the Throttlestop yet we only put in between .43-.47 of a second when conditions allow. The other time (for 8.90) is made up further in the pass and will always run 150-151mph. With a Weatherstation (the handheld device you see the teams with, which we don't have.) you can choose your best setting by the humidity, temprature, sea level etc making the Throttlestop a lot more accurate. The hardest bit is actually learning what the stop does to the car and now we are on course with it (run 6 8.9X somthings at the Euro Finals) we will have a setting to go back to for most conditions hopefully.
There is also a lot of different ways and times in the run to activate the Throttlestop. For example we activate ours after .90 of a second so it has activated by the time we pass the 60ft beams and this is with the throttle 100% off and then the momentum of the car lets it hook back up the track. If you watch people like Jon Morton or Pete Cresswell though, you will see at about half track there car will go into half throttle for about 1-2 seconds allowing it to slow just enough. It's all about preference and what you and your car would prefer.
The throttle stop we use is a blade type as we cannot run the plate system under the injection system we use. This consists of an air bottle with a line leading to the throttle blade with a solenoid in it and when the system activates it throws air into the line jamming the throttle of for the programmed time before realeasing the air and accelerating off.
If you want to know anymore just ask, I am going to hide in the corner from the Throttlestop haters now...

I have to say, I don't like throttle stops. Especially taking a 7 second car and waking in a huge throttle stop to run in Super Gas.
I have huge respect however for people who run in the x.90 classes by the seat of their pants - thinking of the Swedish Volvo with a blown Donovan here, and I think I am right in saying Dave Cherrett runs his gorgeous Dark Revenger van without a throttle stop.

Ft, cheers for the reply.
I see from that there is more than one style then ?
Im not sure if Im a fan or nor, but the fact is .90 classes exist, and if you want to win, then I guess running a car that exceeds the index with a stop is the way forward.
Im a fan of any techy stuff in d/r, particularly throttle stops or N2o stuff, just find it really interesting.
Respect to anyone who runs an index without stops.I used to run 10.90 bike, but wasnt quite onb the index, so never had the problem.

Fury,
Have a look here, it gives you the list of different types of stops available.

We use the blade system as out Flying Toilet Injection system cannot accept the plate as it would clash blades with the Toilets Butterfly.

Have to admit im not a throttle stop fan myself but being a bracket racer i have a lot of respect for the guys who read the weather/track conditions correct and get it right. not an easy feat
I Agree! We have just started to use a Stop in Super Gas, we did struggle to compete with the other teams, and I think we were the last ones not to use one.
I'm not one for shouting off on forums, but if thats how you need to win (in the super classes) then throttle stops is the way to go!! )'Flying toilet', will know what i mean but end of the day its what you like and how you want to run realy?!
But a reply to 'time machine' if you want to run a MPH car (malcolm francis running 170+ with 632) then you have to take a 7 sec car! Then the over bloke/woman doesnt know when your coming, look in america they all running 165-175!!
But at the end of the day if you want to win in the 90 classes then a stop is what you need Good luck to all at national finals!

sorry, but a throttle stop is not "needed" to win in the super classes; they're now much more useful becuase everyone uses them, yea it makes life easier but you can build a car to run 8.90/9.90/10.90 without one
plus look when Al O'Connor comes out in Super Gas, no delay box, no throttle stop and hes on the 9.90 numbers

It's an argument which has been around for ages, and there is no right answer.
Some people like throttle stops, some don't. Much like some people will love a rat rod and be bored of billet while others don't see the point in rat rods and adore the latest high dollar billet roadsters (I'm in the rat rod camp here for reference).
Personally throttle stops are not my thing - I find the racing slightly tedious when the cars don't run to their full potential and appear to stumble mid-run, even if it does make for close races at the stripe. It is simply not what makes me tick - it doesn't mean I hold low opinions of people who use them and I am sure there is more to them than just telling the car to run an 8.90.
The important things to me in drag racing are to have fun, to chase your PB, and to enjoy what you do. I like winning - I am sure everyone does - but it is not the be-all and end all to me. I derive greater pleasure from knowing I helped get the car down the track, from learning which tuning tricks work, and from getting things right. If all this comes together in a winning run then fantastic, if not then so be it. I'd rather break out and run a p.b. than run a throttle stop, but that is just me.
After all, this is why there are different classes.

When was the last time you saw Al O'Connor in the final? yea hes still the main bloke but when was the last time you saw him in the final round, throttle stops rule the .90's classes end of!
And exactly what 'time machine' said sums it up: 'After all, this is why there are different classes.'
I think you are misreading throttle stops Collin. The current Super Comp champion does not use a throttle stop. So now your calling Al O' Connor cause he hasn't been in a final for a while? The thing to remember is that he is adjusting to his new engine and that takes time. Especially when you slow or speed the car up by adjusting the carb. Throttle stops are very useful tools and when setup are definatley a major part of todays Super Classes. This debate will run and run...
As for speeds in Super Classes, it's not essential!

I'm not good with technical stuff but... Spencer ran for two years in Super Gas with no throttle stop. The car certainly did not run 9.90 each run. He coasted from 1000ft and gained entry into more finals than i can remember.
Putting a throttle stop on it this year has not caused a headache but certainly not as many finals as he used to be in. I blame the jelly belly. There are so many worthy and excellent drivers these days, its not the throttle stop but the judgement used on crossing the line and of course those startline reactions.
I'm sure this was on DW sometime or other!... *scratch's head*
