Is it the same for everyone???
 
Ever since i put my turbo on about 2 months ago i noticed that every time i pop a charge pipe and car starts to run N/A it pulls like ass... just nothing compare to what it use to pull like back before i put the turbo on... is this ---- the same for everyone? or is it just me...

with the turbo on but not boosting, your exhaust turbine is a huge restriction. That's why your car "runs like ass", and I don't know about everyone, but it definately does that on mine (or did, see other thread ::))

well you have a turbo blocking your exhaust and too much fuel, what would you expect?

yeah too much fuel with no air to mix is bad that whats the boost is for ;)

he wouldn't have too much fuel without the pressure in the manifold. The problem is caused by the exhaust turbine.

which car is he talking about? doesn't he have larger injectors?

Even if he has larger injectors, he also has a way to control them, like a SAFC, either that or he has an fmu. Withouth the positive pressure in the manifold that the turbo creates, whichever fuel control device he is using won't flow the amount of fuel used when in boost--it will be like running in vacuum.

good point

i am running Uberdata, with 450's on a z6 motor running a t25 turbo but i am running beerbongkicksass map for a T3, so yeah it's a tad rich :-\ but aren't i rinning pretty much an OEM map scaled up for 450's while out of boost?

exactly, i drove my car with 450's and an uberdata base map before i was boosted, it ran perfect, it doesn't supply the extra fuel until it sees boost or else you would be rich in vacuum regardless, but there's still a slight restriction in the exhaust.

well yeah but he will be running extremly rich. I dont know whats his setup but the hack is just used for tunning not to make your car go. You can't expect to run with just larger injectors and a hack you need the turbo to do that.

---- maybe i should pull the turbo off and see how well it'll run without any restrictions? ;D

or you should just fix the charge pipe and keep driving with the turbo, it's not a restriction if the boost is reaching your intake manifold ;)

you can use the hack for n/a too...but when a charge pipe blows you will still run richer than you should because even without boost, the wot settings are gonna be too rich for n/a

oh i fix the charge pipe every time... time to get some good hose clamps and toss the home depo crap

what the hell are you talking about? ??? if you have dsm450s and an SAFC, running your car with your charge pipe disconnected is similar to running your car in vacuum. Even if your turbo is connected, most of the time you're running vacuum. The SAFC simply corrects the signal from your map sensor to allow your stock ecu to run the 450cc injectors. This is true whether or not you're in boost. You can take a stock honda, add dsm 450s, an SAFC, and no turbo, and be able to run it perfect. You can make it run rich/lean based on what your SAFC settings are. It isn't until your MAP SENSOR SEES BOOST THAT IT STARTS FLOWING MORE FUEL!

Sheesh. End of story. :P

home depot clamps/couplers own me too :P i blew one off the other day at 13 psi, all i heard was 'pop' and the car fell on it's ass, i thought it was done, so i got back on the gas a little and heard the turbo spooling, but no boost, and no funny noises or anthing, so i knew i was alright.

not necessarily, depending on your settings

that's true, i'm going on the assumption that it was tuned to run the car semi-decently (unlike 80% of the SAFC setups out there :-X)
