Brake Boosting...how to pull this trick off?

[Wagonbacker9]

my vac is around 24 at idle.. normal?

I've ventured out of my domain here... so honestly, I have no idea. lol. sounds about right though.

24in.Hg at idle? I've never seen a vacuum that high at idle...

 

[Wagonbacker9]

the general rule is as long as its not too low, everything is fine... too low = boost/vac leak...

 

[mattj3636]

yeah, when i cold start it, its like 16-18-20 but when the cars warm, 24...

sometimes its 22.. but recently 24

+1

 

[Wagonbacker9]

having it be higher when cold makes sense. Idk if your cars crack the throttle or have an IAC or what... but usually the car idles higher (under less vac) until it warms up..

 

[HOBDisease]

Ms3's idle control is incorporated into its drive-by-wire system. I believe it does crack the throttle. I don't believe IACVs are used with drive by wire systems.

ya learn something new every day... wouldn't have guessed that on a long work day the thing I would learn would be about an MS3.. but hey, whatever!

 

[HOBDisease]

Haha yah, I'm still against brake boosting unless I'm rich or desperate.

 

[Wagonbacker9]

i'd have to agree... don't think I've ever needed to win so badly that it was worth hammering on basically everything in the car that spins....

This thread is ******* painful. I can't believe there are 4 pages worth of posting bulls*** about "brake boosting".

You hit the brake, and hit the gas, and build full boost while staying at the same speed.

If you pussys are to scared of "breaking something" then why even bother racing. Or actually, heres a thought, sell your cars to someone that will actually push a MS3 to its limit, buy a Kia and continue to play it safe.

Unlike others, some people actually take care of and appreciate what they invested in with their hard earned money. And what do you consider taking it to the limits? Autocrossing everyday/Drag racing everyday/Dumping the clutch @ 6000rpm everyday/no-lift-shift every time/top out the car everytime you go on the highway/and what else? I need your definition of pushing it to the limit, you "hardcore driver". I hope you really don't treat every car you drive like you talk.

 

[mattj3636]

he also sleeps in his car with it running while he holds it at redline all night too

 

[HOBDisease]

Haha that would not surprise me considering that he takes his ms3 or whatever he drives to the "limits".

Please s*** talk me in your 105 mph cars.


Push the limits of a car......? I'm talking about the MS3 guys that have an intake and drag radials and run high 12's. Not the MS3 guys that have full exhaust, intake, boost controller, Cobb tuning, etc etc and still run in the 14's. I put my "hard earned money" into my cars and push them at the track, or don't hold back when a heads/cam LS1 wants to go from a 40 bump.

I drive slow on the highway and my car doesn't see full boost/redline unless its at the track or when I'm tuning it.

im pretty sure the point he is trying to make is that there is no reason to have a post about brake boosting...per the name brake boost there isnt much to understand...use the brake while you are at a roll and hit the gas then let off the brake when you build boost...not hard...no "trick" involved...and no reason to be scared of breaking something...

Exactly!

Its so ******* simple. And anybody that says they are to afraid of breaking something then just needs to sell their cars and log off.

Umm...so what you're saying is...MS3 owners in the 12's that bought an intake and a set of stickies are people that take their cars to their limits, but on the contrary, MS3 owners that didn't buy a set of stickies knowing that it wouldn't be cost effective for them because they only see the strip occasionally but instead went for mods that they don't have to take off just to drive home are people that don't deserve to own any type of decently quick car and should just shoot themselves in the head because they're wasting the car..... Umm.... Okay, I understand now.
