That seems like a good bet -- it's probably Teflon, I'm guessing. [/b][/quote]
Teflon is highly unlikely. Teflon melts at 325 F. Most coatings are a ceramic type for thermal and anti-wear.

 

At what point did we start talking about casting two metals together? Im lost. The whole point of this thread was to bring out the issue that Ford has decided to once again move the ringlands closer to the top of the piston. Something that anybody with two performance braincells to rub together will recognize as counterproductive to any type of power-adder.

Oh and BTW; 16lbs of boost on a Stock 93 Cobra Shortblock. (yep, thats right. Hypercast pistons and all) 520hp/530tq. 130k+ miles. Somebody please argue with this, please.

 

A couple of months ago I called Kenne Bell and spoke with them about S/Cing the Stang.

They said they did not have any physical testing done of the 05 yet, but they expected it to be similar to the 04 in terms of the amount of boost it could take.

Their kit for a Stang with stock pistons is 8 lbs., I believe. If I can run 8 lbs. on my 05, I'll be happy. From what I've read on this thread, that is doable. If I decide to go nuts and prep the engine for major boost (12 lbs. or more) then I understand that I'll have to spend some major dough.

So far as I know, Ford has always designed for naturally aspirated moddability, not forced induction. So they aren't really screwing us modders, they just didn't design for superchargers or the bottle.

 

Why keep changing the subject. No one said it would ever take huge boost. No one is comparing it to a 93 cobra. We were comparing it to previous 4.6's. Has anyone said it would take 16 lbs of boost? Has any 4.6 gt been able to take 16 lbs of boost for long?

Bottom line you started out by saying you COULD NOT supercharge the 2005 (not take moderate amounts just like every other 4.6 gt), you have since modified your posts because you were proved wrong and everyone called BS on you.

The fact remains thousands of people have supercharged 96-2004 stang and people will continue to do so with the 2005+ models. This is a far cry from not being able to supercharge a car. Whats so hard about admitting that? You jumped the gun. You got some bad info and presented it in a way that misinformed everyone who read it.

Post all the snide and defensive remarks and references to cars that have nothing to do with this topic that you want. If it makes you feel better go for it. Most of the people posting to this topic appear to know the truth by raising all the B.S. flags.

We arent against you personally, so dont take it that way. There are just a bunch of guys here that know a thing or two about cars and supercharging. People think more of a person on a message board when they admit their mistake, but often times they keep arguing until they have buried themselves.

I give you a big hug.

 

I sent Kenne Bell a note about the '05 a week or so ago, and they implied that they were planning one. From the rest of the note, which I don't have now, it sounded like they didn't have a car to begin with. I would take "soon" to mean eventually not soon.

 

Nobody changed the subject. We are still talking about hypercast pistons in Ford engines. Problem?

This statement right here tells me you did not truely read and understand the quote that I posted. You only read the "misleading" title, which I did admit was a little misleading, but changed it to reflect the real purpose of the thread.

You have yet to address the real issue of this thread, which further proves your lack of reading comprehension. I encourage you to re-read the original post and pay attention the words used in the statement, they have meaning.

You can supercharge a Go-ped too. So what is your point? I am still waiting for anyone to show me where in that original post were it specifically states "YOU CANNOT SUPERCHARGE A 2005 GT".

Snide and defensive remarks? Heck, you haven't even address the real issues. None of you are Ford Engineers Powertrain and/or a tuner that has access to a 2005 GT engine, don't try to play youself out to be. Unless you are one of these people all the "BS" or "thats a lie" comments just show the true ignorance based on "what makes sense". But yet, only one person has really addressed the real purpose of this thread, to discuss the engineering implications of shortening the ringlands on the hypercast pistons.

Admit what, that you did not understand the post? I'll admit that. You missed it not once, twice, but three times. Sure, you may know supercharging to the point of air in air out, but you obviously do not understand the engineering aspects behind it. Please quit talking above your means, people don't think highly of it. Don't say you weren't because you have yet to bring any tech to the thread, only "comments".

351 Stang is just about the only person that truely understands the post and its content, and he approached the issue with the same feelings I had. (But thats because he's a fellow engineer.)

Hug declined. Trying to be cute scores no brownie points with me. You called ME out and have yet to address the original issue except to beat the dead horse of "you said you cannot supercharge a 05 GT". how about that? I even said thats not what I meant, but you continued on down that road. Refer to my comment above about reading comprehension.

FYI; unoficially Roush is building a non-working supercharged 2005 GT to be unvielded on Nov 18th. The rumors behind why its a non-working model was due to required "internal engine modifications". Sure is drastic measure for 8psi or less positive boost pressures considering past Roush GT's did not have such modifications on base supercharged GT's.

As far as I am concerned, this thread is done. It is obvious that some have grasped the technical data in this thread and will research it before modifying their GT. This is/was my original intent. As for the others, sorry it was so confusing, but maybe you should ask questions first before spouting off answers.
