blown turbo if you overspun it.

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

mycrx

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.

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 ---- *** the ---- out of this thread.

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

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.

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?

mrnubs1

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?

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?!?)
