Hi all! We have been experiencing an issue on site where threads have been missing the latest postings. The platform host Vanilla are working on this issue. A workaround that has been used by some is to navigate back from 1 to 10+ pages to re-sync the thread and this will then show the latest posts. Thanks, Mike.

Boy Racers Air Actuated Clutches?
-
24-06-2008 11:50pm#1I guess I'm illustrating my lack of knowledge now but what the hell is the story with the air brake sound that the toy racers (sorry..boy racers
) seem to have on their Starlets (sorry......Glanza's) every time they use the clutch. I assume its some kind of air actuated clutch? If it is an air actuated clutch what is the advantage over a regular clutch? 0

that's called a dump valve or blow off valve

Nothing wrong with asking a question, just funny to see the smart assed answers AFTER the question has already been answered by Colm Mcm :rolleyes:0 -

Thanks Tuxy. At least now I dont feel as stupid!
Funny thing is that there are probably other people out there who didn't know what caused the sound either. Or maybe not......................:o0 -

Thanks :rolleyes:No seriously I couldn't resist..
In fairness, it wasn't a bad question, it was quite a good one. It was just a very funny way of calling it.. seriously it made me laugh.. No offence!!
Just out of curiosity, how did you come up with that name ? :eek: It sounds so clever..0 -

Guys we are all forgetting the point here
A dump valve makes your car go faster (at least 1000bhp) and makes your cool looking car... sound cool too! LOL
Yeah I hate them to be honest It's not even a good solution to the problem. Recirculation or waste gate is better and its not as noisey
Also I don't like em as it gives the "impression" that the car is going faster than it actually is... and the "curtain twitchers" will be going Joe 90!0 -

How do you mean?DemonOfTheFall wrote: »Wouldn't hold anything against a boy racer for having a dump valve...
Would hold a lot against the 90% of cars that make dump valve noises that are just fake dump valves though
Do you mean that some guys buy some kind of "system" that just gives off the noises without actually doing anything?
Thats pretty sad alright!0 -

You'd get more pleasure fitting out of fitting something like this, but it would probably get you in alot of trouble

Dont forget graham that your evo is a recirculating system, but some cars do vent to atmosphere, so recirculating wont be the best option for them such as Glanza's or Sti imprezas.
i had one on my evo for a week but it didnt take to it well, kept cutting out when you let off the gas, wasnt worth the hassle of fitting a stabilising set to control the thing so i settled for reversing the standard plastic recirculating valve.0 -

Yeah, my engine was designed for a recirculating diverter valve also and the use of an atmospheric valve will cause a rich fuel mixture due to the loss of already metered air which the ECU is expecting to remain in the system. When the air is vented, the ECU dumps fuel into the system expecting the air to be there, and it's not. This rich fuel condition can sometimes be severe enough that the ECU cannot compensate for the condition and the car will run rough or not idle properly 0 -

Pass no heed of them hornet, shower of big bullies. I can see where you are coming from with the clutch thing. Obviously you heard the pisssst sound when the car was changing gear and assumed it was to do with the clutch. I hadn't a clue what the hell it was either for a long time and used to stare at the Glanza making it as it tore off up the street, all aerials and blue luminous under lighting with the standard skobie looking fecker behind the wheel. Just like everyone else on here i had to ask/learn/look it up to find out what it was and like most on here i looked stoopid when i asked.0 -
Yep. That was it Fossie. Assumed it was to do with the clutch because it coincided with the gear change.Fozzie Bear wrote: »Pass no heed of them hornet, shower of big bullies.
