GT500 - Power or Weight?

[Nameless]

The DCT alone is 86lbs or so heavier that the 3160 lightweight model in the 350.

Wheels, brakes, tires, rear axles, thicker antiroll bars, potentially strengthened steel differential pumpkin cover. I’d say another 50-60 pounds there.

Blower, coolers, fluids, plumbing. Add another 125-150.

I believe the cross plane 5.2 is also slightly heavier than the FPC equivalent.

Larger diameter exhaust, manifolds. Add another 10 pounds.

Not sure if they had to add additional chassis reinforcement or not. Guess no.

All in all I can see 300+ pounds over and above a track pack 350. 4100# at least.

Hopefully an R at 3950-4000, but that’s the best we’ll likely see. I hope I’m wrong :(

Edit: add another 10-15 lbs for the emergency brake calipers, pads and linkages. Secondary calipers the 350 doesn’t have.

You just killed the vibe but you're right, it would make sense that the GT500 weighs around 4100lb.

Can I have a 650hp & 3,500 lb car ?

You can...unfortunately it only has 2 seats and sits about 3 inches off the ground. it goes by the name Corvette.

I don't think the CPC will weigh more than the FPC engine. I am thinking the CPC will have a lighter crankshaft. The FPC has balance shafts that add weight. The super charger weight will add to the total weight of the CPC, but we don't know how much the SC weighs. So, the CPC with the SC may weigh only 20 more pounds than a FPC.

Haha my base weighs 3500#'s now.. still looks 100% stock, haven't even went to lighter wheel/tire combo yet. But i sit a lil higher then 3" lol

Why would the CPC crankshaft be lighter? Didn't Ford engineers say that the Voodoo crankshaft is lighter than the Coyote's because the Coyote is a CPC and they tend to be heavier? Do you think that a crank designed for a supercharger belt might need to be stronger, hence heavier than a crank for an NA engine? Do you think a crank for a higher HP engine might have to be stronger?

Balance shafts? What engine has balance shafts?

Don't you think a car with boost will tend to have heavier pistons than a car with an 8,250 rpm redline?

I disagree with everything in your post, but please educate me if I have something incorrect here.

I don’t agree here either.

Voodoo 13lbs lighter.

:shrug:

Don't you all think Ford engineers will use all the knowledge they have gained in building the FPC and previous CPC engines to make the GT500 CPC V8 as light as possible ? I do.

Nope

Of course they will, but that doesn't translate into the GT500 CPC V8 being lighter than the Voodoo.

Maybe they will make the GT500 another FPC to keep the crank light, but my belief is that the GT500 will have a CPC, which requires larger counterweights. I also believe the GT500 will have a blower, which will require a stronger, heavier crank (given similar material construction). I also believe the GT500 pistons will be heavier than the GT350's.

Nah! I don't think ford is out to redesign this whole car for an outgoing platform. They are going to use what they already know and have and make it work. Example, the headlights they didn't want to create a new support so they just used the one in the GT350 and thus we get the old style lights. I get it.

It doesn’t actually work like that. If the ‘base’ design is a cpc coyote then it won’t have lightweighting. So I heard the block will be gen 3 coyote and the valve train and heads, top end etc will be gen 2. It sounds like a Frankenstein engine. It won’t be the newest DI/PI either from what I know. Just port injection.

More new technology omitted from the halo car lol. :hail:

They need to save it for later :lol:

Also, maybe the budged didn't let them (right now).

This is completely inaccurate. The FPC Voodoo does not use a balance shaft. The FPC 5.2 crank is lighter than the 5.0 crank.

As I recall, Ford uses the term torsional dampers to reduce the vibration associated with the FPC.
