The rear entry blower on the 2003 cobra? Will this fit on an L?

Also notice there is only ONE belt!
And is the an SVT logo I see on the front plate of the blower??

 

01Lightning, Yes it does appear that it is. Same as the one on my 02 L.

 

Didnt even occur to me! Man. And look how close the lower pulley is to that idler... Theyre trying to make it difficult.. Im sure that there was limited space. It does make for a clean looking install.

Changing the lower pulley would not only speed up the blower, but everything else! I guess if you wanted more boost you would have to change the upper pulley, and there can be problems associated with that!

 

There are two belts: (Photo courtesy of RobG)

 

Yes, but the one that drives the blower is also on the alternator in that pic.... Maybe things will change by production?

Also looks like what I thought was an idler, is the powersteering?? The one just to the right of the blower pulley... they are pretty close together.

i think you would have to use under drives with a set of blower pullies

 

How the heck would you change the belt behind all that stuff?

 

same way you change the belt behind all of our crap. lol

 

Just looking at that engine frightens me...

 

That's a smaller blower than what's on the L isn't it? I believe Saleen, Roush, etc. using the Eaton M90.

 

OK -so it's a 4.6 and has a smaller blower but puts out 10 more HP than the 5.4 L. Have they just used a larger pulley and beefed the internals? Anyone know how they're getting higher numbers?

 

It has to do with the Cobra's 4 valves per cylinder and 7000 rpm redline. The larger pulley is actually to slow the blower speed down on the higher revving 4.6 liter 4 valve. Naturally aspirated the Cobra engine was rated at 320 HP vs. the 260? HP rating on the standard 5.4 liter engine. It is amazing that Ford is only picking up an additional 70 HP from the blower on these engines. Many of the centrifically supercharged Cobra's are well over the 500 HP mark.

P.S. I also have a 70 Mach1 project(for 22 years now) and a 70 Sportsroof project(for 20 years now)

 

The tech said the 4.6L DOHC was majorly detuned. Only 6lbs. of boost is being put out right now.
Just wait until tuners get ahold of that.
