how much will GT500 hold up to?

Ho_Edge · May 13th, 2010, 06:06 PM

just curious....i've looked around and havent found it. What will the stock internals/block hold up b4 going poof?

not that i'm gonna be buying a new car anytime soon, but when it does come time, i'm thinking of going with used 06-07 gt500 instead of a 2011 GT. i'm sure the GT isnt gonna hold up to much more than 500 rwp safely. just curious what the gt500 tops out at safely

How much power are you looking to make?

Doc8224 · May 13th, 2010, 06:16 PM

They will hold 700+ Do you really need more than that? LOL

Ho_Edge · May 13th, 2010, 06:18 PM

My shop has an 07 GT500, just installed the new KB Mammoth - laid down 797 on stock guts

Thumbie · June 5th, 2010, 06:14 PM

holy hell that's a lot of power. But teh stock internals are all forged, right? So I guess that makes sense.

weems · June 6th, 2010, 09:35 PM

Yep, all forged.

V6 Pony Car · June 6th, 2010, 10:59 PM

I think like all recent motors from any manufacterer the pistons are the weakest link.

RC04SVT · June 6th, 2010, 11:24 PM

Just keep a good tune on it, ull be set

The Internals are infact Forged, but the gt500 use's the powered coated rod's one's similar to the ones found in mach 1's there's has been an estimated limit of at least 700 + hp at the crank on stock internals.

97mustanggt · June 8th, 2010, 02:01 PM

for the gt500 just get some sticky tires and youll be satisfied for a while...and you can pretty much get one pretty cheap

The rods found in the Mach 1's are the same weak powdered metal rods found in all 4.6 liter motor's sans the 03/04 cobra. The GT500 rods are stronger than that. Plus the the rods in the 4.6's will never hold 700+

F8L 500 · June 9th, 2010, 09:35 PM

Alot of gt500's have over 700rwhp. I only hear about rods breaking when they have 800+ rwhp and it's usually due to tune. I have over 600 so we'll see how well she holds up when I get back

You do know the Mach1s and 03 04 Cobras come with Manely rods that are rated at 700hp and there has been allot of Cobras with 700 to 1000hp running these stock rods for more than a year and have never broken or have had any problems. The Shelbys Gt500s are running Mahle rods which are stronger and could easily hold 800hp to 1000hp all day long with the right tune.

You do know that you have wrong info right? The termi's have the manley forged H-beam rods but the mach's have the same powdered rods as the gt's and pre-termi cobra's as I said in my previous post. Do some more research before you dog people who are right. As for the I-beams not H-beams in the Shelby's they are good but not as good as the termi forged H-beams.

Proof positive as you can see here in a picture of my stock rod/piston combo out of my Mach 1 when I tore it down. notice the powdered gt type rods not forged H-beams.
