that’s cool. everyone likes something different. I can see why you would definitely not want a blower on your car. and like I said before, I really hope that they come out with a really strong motor that is NA.

as for the autocross, I don’t think I could ever get into it. I like road racing more than anything because you can really push a car to its limits in every aspect. I don’t actually road race. I have been a few times to the track (buttonwillow raceway) with green flag driving assoc. they hold "open track" days and they are divided up into 3 classes. it is cool because you can really push it without worrying too much about guys bumping and grinding. its also cool to have guys in expensive sports cars (vettes, Acura nsx's, porches, etc) come over after a session and tell you how surprised they were to see how quick that old red camaro is. and that was when it was bone stock.

I have raced the pony express 100 (a timed road rally) in Nevada a couple of times and done pretty well.

well, cheers.

 

 

Since I am the one that threw the 100lbs of weight out there and several people got a little upset over it I will explain myself a little better. That number is a worst case scenario ball park figure. Most of the other posters on here are actually more correct. Since I didn't have a scale handy when we were swapping out blowers I would guess that the supercharger/aftercooler assy. weighed somewhere between 40 and 50 lbs. Then there's the plumbing, waterpump, heat exchanger, fluid, etc. So I just gave it a ballpark worst case additional 50 lbs for all that. I bet the real difference between these two hypothetical (sp?) cars would probably more like an LT 4th gen and an LS 4th gen. BTW, out of curiosity, do the LT cars handle worse than the LS cars? I actually am curious about this.
And to the poster who for some reason got offended when I said that 99.99% of people won't see the handling limits of their car, I still stand by that. While there are a few of these types on this board their numbers are far, far fewer than those who explore the accleration limits of the car. A top of the line car full of luxuries is not going to a wise choice if you want to go SCCA racing. And please don't think that I have never put my car to the test on more than one occasion thru some twisties. I just think that the difference in handling between these two cars wouldn't be great enough to justify the loss in potential with an N/A motor.

Really I think this is all moot anyway. I do believe that we are both going to get our wish in the end. Probably sooner for the N/A guys lol.

 

Has anyone considered how much weight got added to the GT500 compared to the regular Mustang GT, just by the simple addition of a supercharger???

Now, have we considered WHY that much weight got added??



Shall we continue to debate this ~100 lbs or less, and how detrimental it supposedly "won't" be??

 

Yeah, because you just can't make a well balanced, efficient FI car.......now where's my 335i brochure.

 

The primary reason I want a factory installed supercharger is I like the idea of a simple pulley swap to improve performance rather than spending hundreds if not thousands of dollars on a naturally aspirated engine trying to achieve the same performance increases.

The factory warranty doesn't hurt either.

Let me also say, I don't drag race, I don't street race, but I want to be able to say I have the baddest *** ponycar on the planet.

 

 

You do realize the engine is a 5.4L iron block vs. a 4.6 AL block, right? It wasn't just a simple blower bolt-on.

 

Which begs the question that was discussed above: Would GM use an iron block or aluminum block with a blower?

 

What material are they going to use for the next ZR1?

 

You'd think aluminum, but haven't there been issues with Al block reliability after 600 hp or so?

 

To be honest, NO, I didn't know that!! But it's completely relevant to my point ..... in Ford's effort to build a "super" Mustang, they beefed up other aspects of the car to handle the power from the supercharger. I didn't know that the block was an iron block (although it doesn't surprise me), but I do believe that the actual structure of the car has been beefed up as well, to strengthen the car for the extra power? Otherwise, why the ~400 lbs weight difference between the GT500 and GT??

 

Another question would be;
What kinda street manners would each have?

Where would the bulk of the power be in the rpm band?

What about the reliability of each?

I wouldn't want to have to trip the rev limiter to get my 500th HP...

 

With GM blocks...I have no clue. Ford used that as the reason for putting an iron 4.6 in the 03/04 Cobra, though to this day, I still believe (perhaps incorrectly) that cost was another issue.

A better case for cost being an issue could be made with the 5.4, as the only OEM 5.4 blocks are those from the Ford GT, which would make them rather rare and quite expensive.

But man does it make for a heavy motor...especially when blown.

it is probably only a difference of 5-10 pounds, but the 5.4 liter motor has a larger displacement blower (eaton M122) on it than the 4.6 FI cobras (eaton M112)....

OH! and i was bored last night and looked up the weight of a low profile blower from weiand. it was 63 pounds total. just thought id throw that out for what its worth....probably not much
