Intake/Exhaust New Dyno Results
No one asked for them, but here they are https://www.thegalantcenter.org/styl...ault/laugh.gif I had 3 dynos done, completely stock, stock muffler but no air inlet duct, and no air inlet duct but with the Magnaflow muffler.
Stock vs No funnel/stock muffler:

As you can see, the factory intake produces more power at drivable RPMs, but once you hit the 4k range it evens out, and without the restriction of the inlet duct it completely overwhelms the factory by the time you reach fuel cut-off. About a 11 whp 10 tq over the stock at the top end, and you really don't sacrifice that much low end, and peak values are gain of about 4 whp loss of 5 wtq. Still convinced of the short ram being plagued by "hot engine air" (or the value of a short ram at all for that matter)?

Are you guys seeing this? The graphs look about the same. The green line is the stock muffler, and the red/blue lines are 2 different Magnaflow runs. I'm seeing about the same power curve give or take only 1 to 2 whp/wtq throughout the entire power band. So is the a straight through muffler really worth it, and is the stock muffler really that restrictive after all? It's up to you to decide.
Well there you have it folks...my dyno results. I tried to get a printout of stock plotted against stock muffler against MagnaFlow muffler but alas, we ran out of paper https://www.thegalantcenter.org/styl...ault/laugh.gif Shoulda printed it first. This was done with the hood closed, back to back runs, air temperature of 78 degrees and humidity of 72%. Different people will interpret these results differently, you must interpret this for yourself. But it sheds a great deal of light on where the restrictions are don't it.
I also walked away with a free Boxster S exhaust :laugh: They were going to throw it away but I said I'll give you 5 bucks for it, but they said that I could have it for free since it was going to be trashed anyway. Now if I can just find a way to fit that massive thing somewhere...maybe I'll put it in my trunk and drill holes out to the bottom of the bumper https://www.thegalantcenter.org/styl...ault/laugh.gif
