What are your thoughts on this ebay item? http://cgi.ebay.com/ebaymotors/ws/eBayISAP...sspagename=WDVW
I wasn't about to buy it, just wanted to know if 6PSI is enough to really double your horsepower. Normal atmospheric pressure is ~14.7PSI at sea level, so let's say about 15PSI. 6PSI boost would be a 40% increase. After factoring in the inefficienty of a turbo, (~75% efficient,) it would be more like a 30% increase in total power. That is a very different figure than the 56% increase the auction says.
Other than that, does this look like a good setup?
If you got an E36 turbo manifold, could you put any turbo on it?
Are there any special electrical things you would have to do on a BMW when installing a turbo?
