Could you please tell about how much it cost you to do this mod? I've been dieing to supercharge my mach and I've seen a few local eatons for sale, but I'm not sure how much everything else costs that I'll need.

@SilverbackGorilla69 With the tune and all the parts (gauges and such), it came to just over $3000 for everything. Some people have done it all for as little as $2000. Just depends on what kind of deals you can get on the parts. If you want it cheap, you have to be patient.

@reloaded183 I dont under stand how 99 , 01 cobras and mach 1's can run these eatons on stock internals. Back in 2000 when svt was testing supercharged engines for the 03 cobra they weren't making it past 8 - 10 hours on the dyno, they were throwing rods through the block all directions. u got me

@IDontHateOnCars Well a lot comes down to the tune and making sure that you aren't running too high of a PSI. I suppose that if you ran the engine flat out for a long period of time, you'd probably have more failures than on a street-driven car that doesn't see max psi for long periods of time and high RPM runs. Some people have helped their engine last longer by shifting at 5800-6500 instead of all the way to 6800

What do you think about a eaton swap? Im considering it..

[reloaded183]

@SIKMACH1 It's an awesome swap. It's still very streetable, as long as you don't go flooring it in first or second. The sound of that Eaton never gets old. And if you can find the right parts at the right prices, it can be done fairly cheap.

@TheHydrocortisone Haha yeah, a 2.76" upper and larger lower would definitely not be good on a stock Mach 1 block. The smallest I ran on the stock block was a 3.4" upper, and that put it right at 9 PSI.

[TheHydrocortisone]

cancel the last response i just realized it has a cobra long block :)

[TheHydrocortisone]

is the stock mach 1 bottom end safe for a pulley eaton?

[reloaded183]

It is tuned, and the light has since been cleared.
