Im gonna get in shit
 

My car has been away all winter and now we got some good weather. I finaly got my car to rev past 2200 rpm and its the first time in 2 mounths and in that time I also installed the bulk of my hmt kit. No charge pipes. iv redone a lot of my body work on the car.
the weather was so nice i had to take it for a rip. the turbo sound is sweeter then listening to a bus go by. it was an awsome 3 minutes. but i havent finished the body work yet........
i have no drv door, drv fender, hood, front bumper on it right now
i guess weight reduction is a good thing. i miss my car so much im going to drive from toronto to B.C. when i pull it out.

Re: Im gonna get in shit
 

you let your turbo spool with no charge pipes :1

Re: Im gonna get in shit
 

thats bad?

Re: Im gonna get in shit
 

hahaha what we have here, is a grade "A" dumbass.

Re: Im gonna get in shit
 

explain my consiquences

Re: Im gonna get in shit
 

Re: Im gonna get in shit
 

how fast do you think a turbo will spin with ---- all to hold it back?

Re: Im gonna get in shit
 

well thats not good, its still ok though i think, wont be doing that again. :3

Re: Im gonna get in shit
 

Turbos feed off of themselves.

+ boost = + exhaust volume
+ exhaust volume = + boost
+ boost = + exhaust volume
etc......
....until wastegate opens to reduce the actual volume of exhaust flow reaching the turbine.

Increased turbine speed is dependant more on exhaust volume than it is on engine speed.

Driving a turbo engined car with disconnected charge piping would be the same as revving a turbo engine car (with charge piping connected) in neutral. No boost :3 ..... or very little......

Re: Im gonna get in shit
 

ummm.... :1


that quote made my day. its gonna be a new line at work.

Re: Im gonna get in shit
 

blown turbo if you overspun it.

Re: Im gonna get in shit
 

:3

Re: Im gonna get in shit
 

um what?" boost is positive pressure in the intake manifold wtf you gotta complicate ---- with your retard theoreys

Re: Im gonna get in shit
 

were not talking about boost you ------- pile of goose ----, boost doesnt hurt it, do you think we'd say it does knowing the charge pipes are not hooked up? with no booooooost holding the wheel to certain speeds it simply over revs the turbo, and they already spin hella fast, no need to over rev them a few x's past what they are designd for, as long as you werent makn full throttle passes, which would be hilarious in a car with no door and ----, haha pics right there :), but yea your turbo is prob fine, i just wouldnt reccomend doing it.

Re: Im gonna get in shit
 

of coarse there is going to be no boost unless the turbo is big enough to boost to whole ------- atmosphere, but yes the turbo will spin wildly. Take your "I'm preety sure you are all wrong even though I know ---- all" piece of ---- ass the ---- out of this thread.

Re: Im gonna get in shit
 

This is completely wrong. An engine during WOT under load does not act the same as a an engine that is revved in neutral. :-\

Re: Im gonna get in shit
 

Well if you're not getting any positive pressure at the manifold, and because of that, you're not getting any increase in exhaust volume (above and beyond NA engine against load exhaust volume) - how is the turbo going to reach dangerous speeds? It's not able to feed itself, right?

I was just saying that without the extra exhaust volume created by positive manifold pressure, the turbo can't reach dangerous/harmful speeds.

An engine under load may not act like an engine revved in neutral, but the difference beween how a turbo engine acts in neutral vs. how it acts against a load is MUCH different in comparison to how an NA engine acts revved in neutral vs. how it acts against a load.

In an NA engine, the load on the engine changes - atmosphere remains constant.

In a turbo engine, teh load on the engine changes - atmospheric pressure continually increases.

Re: Im gonna get in shit
 

no. i turbo needs a wasregate to reguate how fast it spins by regulating how much exhaust gas actually gets INTO the turbine. without a wastegate (which he doesnt have because wastegates work off vac/boost), the turbo is going to be spinning as fast as the exhaust gasses will allow it to spin, causing it to overspin and explode.

easy enough for you mrnoobs?

Re: Im gonna get in shit
 

Not really.

I thought a wastegate was used to regulate boost pressure by diverting exhaust away from the turbine, independant of how fast the turbine spins.

According to you, what he did would have caused his turbo to overspin and explode. So, why didn't his turbo explode?

Re: Im gonna get in shit
 

The main point in this thread so far that I have gathered is....

DO NOT DRIVE YOUR CAR WITHOUT CHARGE PIPES. EVEN IF YOU DON'T DO ANY DAMAGE IT IS STILL COMPLETELY POINTLESS SO JUST DON'T ------- DO IT!

No need to argue over a poinless point (if that makes sense?!?)

Re: Im gonna get in shit
 

or just open the wastegate. ??? unless the turbo is super tiny it shouldn't spool

Re: Im gonna get in shit
 

yeah, your right. the wastegate does route exhaust gas around the turbine wheel. but how is the wastegate gonna open when it doesn't see any boost?? it's not. so, exhaust gas is still going to go through the turbo and will keep spinning the turbo faster and faster. how hard is this to understand?

Re: Im gonna get in shit
 

i will send a pic in here for u guys
i think i just had a bit of winter beater feaver

Re: Im gonna get in shit
 

so your saying that a na engine wont spin a turbo thats free to spin as fast as it like with no restriction because it doesnt make enough exhaust volume? If this was true then how the ---- would you ever get it to spool up when the charge pipes are hooked up and has a restriction ? You my friend is one dumb ass ------.

Re: Im gonna get in shit
 

Yeah man, I'm actually only half black. So, you're only half right with that completely relevant point.

Last point for me in this thread.

The turbo, like any other fan, is free to spin as fast as the air/exhaust directed at it propels it. It's not free to spin as fast as it wants. A fixed amount of exhaust will only spin a turbo up to a certain speed. A turbo won't just keep spinning faster and faster with a fixed volume of exhaust propelling it. It always requires more exhaust to increase it's speed.

If you rev a turbo engine in neutral, you'll see 1 to 2 psi on a guage. If you put the car in gear and drive, you increase the load and start building boost pressure - the engine is moving slower and the compressor has more time to pressurize the intake. Then the cycle of +boost/+exhuast volume begins.

The NA engine will spin the turbo, but only to a fixed speed since NA exhuast volume (even at WOT load) is fixed. I'm saying that even at high NA engine loads, without boost to help increase the amount of exhaust available to spin the turbo, the turbo will never reach dangerous or harmful speeds. It might spin faster than it would if charge pipes were connected and you were revving in neutral (1 -2 psi), because of the higher load when you were actually driving. I don't think it would harm the turbo, though.

That guy was right, It really isn't worth arguing about and we obviously don't agree.....so............connect the charge pipes and go.

Re: Im gonna get in shit
 

I like how you generalize the whole thing, a t25 on a 350 v8 would be alot different the a t3 super 60 on a lawn mower. what you think and what I and the other turbo educated guys know are two different things princess.

Re: Im gonna get in shit
 

No man, I completely agree with you on that point. :y
