[edit] Chrysler/Dodge VNT material
76.17.61.168, your continued insertion of unsourced, POV original research is not appropriate. My vehicle ownership history is just as irrelevant to this article as yours. It also doesn't make any difference how cool you or I may think the Turbo-IV cars are. Remember, the standard for information in Wikipedia articles is not "truth", but verifiability, and assertions — especially those that can reasonably be challenged — must be supported with citations from reliable sources. It doesn't matter what you or I or anyone else knows or thinks he knows, it matters what we can prove per Wikipedia's requirements. Please try not to take it personally when text you've added to an article is modified as part of an effort to improve the article according to Wikipedia's standards. Please also take a few moments to click the links embedded in this comment to learn more about how to make your contributions more likely to remain part of the article as it evolves and improves with the effort of all who choose to participate. Remember, Wikipedia is a coöperative effort, not a competitive one. If you carry on inserting unencyclopædic text and not engaging on article talk pages, you run the risk of being blocked. Thanks for choosing instead to coöperate. --Scheinwerfermann (talk) 18:16, 30 January 2008 (UTC)
[edit] High revving?
Isn't one of the points of turbochargers that while you can't run the cylinders at high pressure due to pre-ignition, you can *force* the air into the cylinder through the inlet valves, and so rev more quickly, and hence develop more power than the simple boost pressure ratio would suggest? Or at least it seems to me a lot of turbocharged engines rev rather higher than normal aspirated ones, there must be a reason for that. If so, this is missing from the article. If not, not to worry :-)- (User) WolfKeeper (Talk) 02:02, 6 February 2008 (UTC)
- I don't think that the higher revving is due to the turbocharger. I think that because turbos have an incremental increase in power as revs go up, that manufacturers use heavier duty springs, etc., to allow for higher revving on their turbo engines; also of course these are their premium engines so they'll spend more money on them compared to base engines.

- No, I'm pretty sure that the extra pressure of the turbocharger permits the engine to force the air through the inlet valving far faster than it would normally go which is especially critical at high revs; but the actual pressure in the cylinder is limited by the octane of the fuel; but if you rev higher, then the engine produces more power anyway, since there is more total flow of fuel and air through the engine.- (User) WolfKeeper (Talk) 19:54, 10 February 2008 (UTC)
[edit] Power output
In the working principle section it says a turbocharger can increase power output 15-40% if the engine is allowed to run lean. Is this a high number? To achieve a 15-40% increase in power output does that means that 15-40% more energy is being release associated with the lean air/fuel condition? Noah Seidman (talk) 03:45, 26 April 2008 (UTC)
