NateZ Posted January 5, 2005 Report Posted January 5, 2005 How come My buddy can boost like 15 lbs or alittle more of boost on his eaton supercharger on his cobra, but magnachargers kinda fall short around 10lbs? Just curious Nate
Dylan06SS Posted January 5, 2005 Report Posted January 5, 2005 i don't think it really matters... with the compression being as high as it is the SS couldn't handle 15lbs of boost could it?
zippy Posted January 5, 2005 Report Posted January 5, 2005 cubic inches to start with. i don't believe they are the same blower though.

The cobra's can only do it on stock internals for a short while.
NateZ Posted January 5, 2005 Author Report Posted January 5, 2005 Im not at all sayin i want to do it on the SS, i'm content with my 6lbs. I was just wonderin. Even the 5.3 guys on ls1tech say there eatons start belt slipping around 10lbs? Nate
ctrow Posted January 5, 2005 Report Posted January 5, 2005 Keep in mind the new Cobras have forged bottom ends from the factory along with obvious lower compression. My buddy that has an 03' is always showing me stuff that's available for them. They're a pretty stout motor.
misterp Posted January 5, 2005 Report Posted January 5, 2005 I am also a fan of the Mod motor - they really are impressive. Just not big enough! Mr. P.

styleandspeed Posted January 6, 2005 Report Posted January 6, 2005 Cobras also have composite rotors in their eaton blowers which allows them to spin faster and create a bit less heat. Also on the cobras you change the lower pulley which doesn't decrease the surface area of the belt on the blower pulley therefore you can spin it faster w/o belt slippage because more of the belt is actually in contact with the blower(upper) pulley. Also a change in the lower pulley size makes more of a difference in how fast the blower will spin than a change in the upper pulley will. Cobras also have a bigger intercooler under the blower which allows them to dissipate more heat so you can run more boost safely. Also as zippy said they are only 4.6L which is easier to fill than 6.0L Aaron
