And What Partizan Said Is True.... With A Maf Based Fi System If The Meter Is Before The Bov And Then The Valve Is Vented To The Atmosphere The Meter Has Already Adjusted For Airflow And When The Charge Reaches The Cc If Its Less Than What Was Metered The Car Has No Way Of Knowing So It Still Pumps In The Same Amount Of Fuel And Runs Rich For A Few Cycles (until Your Back On Throttle).

As For Race Cars.... Most Turbo Race Cars Use A Map Based System Which Is More Precise And Better Because It Monitors Plenum Pressure So Even If The System Is Vented Atmospherically It Can Still Adjust According To Plenum Pressure. High-end Systems Use Both Or Dual Mafs For Correction Factoring.

Once agian, 14.7:1 A/F is teh roxor 4 teh tubros!!!



They run rich because its safer than running even a 13:1 id rather have a touch less power than a hole in my piston


There is no spoone -teh matricks.

Maybe i should clarify what i mean, i mean with a map that is (as i understand the term "rich" to mean) using too much fuel for the turbo to match with boost.

Argh. anyway the Mars Volta is AWESOME, man. Chek out de-loused at the comatorium if you want a great concept album

running rich is a map where too much fuel is fed to the engine, the turbo really has nothing to do with it besides feeding more air (hence more fuel yada yada). your original statment was something along the lines of " [running rich with a turbo is Dumb]" followed by "do you honestly believe that someone with a turbo that is set up CORRECTLY is going to run rich" thats really a pretty stupid or vauge comment. Running rich is really no big deal for the turbo system, technically it would take some heat out of the exhaust which could lower the energy getting into the turbine but thats a long shot. (prolly last longer anyhoo) If your talking about a fuel map so shitty its about 9:1 or something redicilus like that. thats common knowledge, and any tuner wouldnt do that regaurdless if the car is turbo or not . now as for backfires and flames while decelerating - where this all started. backfires are caused by an over-lean condition where theres not enough fuel for the plugs to light off fuel goes out the exhaust - gets hot - boom. flames are caused by either being too rich (caused by shitty tune) or lots of misfires (shitty sparkplugs) RedFC has both... hence the rotary potato style 15 second flame.

The only real thing I can think of thats bad for a Turbo fuel wise is if you have a WRC stlye anti-lag system. but really thats something completely different

well all the cars in my vids that blow out flame dont seem to be "shitty tuned" so yea......or any race cars i see on tv, all styles of racing. so i guess there all just shitty tuned since they blow out flames. I THINK NOT

[S13wanabe]

Most race cars only shoot a flame for a split second though. If there is a flame there for an extended period of time, like a couple seconds, there probably is something wrong with the tuning or the motor. I'm no expert at all, but I autox and drag, and watch racing a lot. All I know is that the RX7 I saw on the freeway that held a flame for a while when decelerating was fast as hell. Since he passed me at least at 150mph, I'm sure something was right with his motor.

[kcap122]

it COULD be because people have their fuel map so that if they go WOT from 1k rpms, they mix starts getting more gas, and because the engine isnt movin fast enuf to use it yet, it just shoots the stuff out the back.....

eh w/e im just talkin out of my ass

[Ace$nyper]

*stiffler voice*
What the fuck is going on?

[musicsurfman]

The Reason Race Cars Shoot Flames Is Because Going From A Wot To A Off Throttle Environment The Fuel System Has To Catch Up To The Motors Decent Rate.... Hence A Rich Condition, Mixed With The Super High Octane Fuel And 1000 Degree Exhaust Pipes, There Is A Flash Point That The Fuel Reachs And Burns Out Before Completely Exiting The Exhaust System. Blue Flames Turn To Yellow As The Fuel Burns Off Cooling Down. My Rb20det Used To Do The Same Thing Upon Deceleration, So Did My 2 Cycle Go-kart, My Formula Ford And My Formula Mazda Back In The Day.

[AWDSR20]

OK OK OK my car "Back Fiers" when i down shift, or keep the gas at high trpm then let go of the gas.
a blue flame and loud pop happens. i like it !
and my car is not shitty tuned!!! it caust me $500 to tune with the HKS f-com!!!
but then i saw a beat up mini van the other day that backed fierd, (no flames just a liud pop!)

[logik23]

Probably cause it's so old and crappy that the timing is off and the exhaust valve opens to soon, ignition happens when valve is opening.
