Difference: MM Engine & Mach1 Engine

[Rider90]

Does anyone know the differences between our engine and an engine from the Mach1? They are at over 300 rwhp with just a K&N drop in and some exhaust work.

One thing I know is the air intake faces left in the Mustang, and to the right on ours.

..also,.. I'm not sure if the Mustang has an aluminum block like ours.

I'm sure someone will shed more light on this...

Yes, they do have aluminum blocks. The mach I's also have the alternators mounted in the middle like our Marauders do. They also have the same compression ratio, but that's all I know. I'm not sure about piston type. But the cranks are the same too. This is a good question this thread brought up. Anyone else have more info?

They've got a big ass intake on top of the HOOD!

It's a big help I'm sure.

I believe the manual transmission has a steel crank, and the auto is cast.

I believe the manual transmission has a steel crank, and the auto is cast.

AND, It has a manual.

I guess Mach 1's are pretty cool then.

I don't mean to sound like an ass.

Okay, thanks for that correction Merc.

Yes but they also have an air intake tube just like we do. I was just informed they believe it is the drivetrain loss with an automatic, since their autos come in around the same power as ours but their manuals are usually 40-50 rwhp better.

Are you saying that there aren't any Mach I's equipped with an automatic?

Another dfference is the Mach1's engine is hand assembled. Maybe it's balanced better??

But not as cool as my Bullitt. . .

or Mackensie. . .

They both have tin foil blocks... Cast iron what it's all about.

Are you saying that only because they're aluminum?

An Iron block is a good practical design for strength and durability. On the down side of that it has the extra weight and heat dissipation problems. In other words.. its heavy and doesn’t get rid of heat fast enough. For applications with superchargers you need a good bottom end if you desire to force a lot of air into the system to achieve grunt horse power, an Iron block is ideal if you want it to stay together. But an Iron block is not always better. Aluminum blocks are lighter in weight and dissipate heat quicker, which should allow the engine to work more thus freeing up extra horse and torque. In applications of racing sometime a cooler running engine can be ideal for consistent 1/4 mile times with out having a heat soaked engine, besides the fact that it doesn’t have the weight where as the Iron block would have to work harder. We all know that weight and heat effect 1/4-mile times and the aluminum block provides another option to achieve better times. There are advantages and disadvantages to both designs however. It really comes down to what application you desire and personal preference
