Rumor - The GT500 thread

The aluminator 5.2 makes 570 hp. Subtract 40 for good measure, of what the OEM will provide. 530 hp and NA engines can double HP with 15 psi on average. That’s 1060hp and the 2650 supercharged can make 15 psi. Probably won’t pass regulations there but it’s what it’s capable of. What we get will probably be in the 800 range, give or take. Maybe 760 on 91 and close to 800 on 93. Maybe we see a specific fuel tune for e85.
EPA, it plays a large role.

I don’t know that much about it, Its the way J explained it to me. ;)

Serious questions: A Demon makes a supercharged 808hp (non race fuel) with 376 cubic inches of displacement; a 5.2L engine (315 cu.in.) with the same specific HP would make 677 HP. With the HP numbers being talked about (>700), what about the anticipated GT500 engine would make it have this level of specific power? The Demon uses it's A/C circuit to assist in cooling the intake charge. Is it anticipated that the GT500 will use similar tricks?

Only need something like that for a drag car. GT500 will do drag but that's not its sole focus like demon.

Thanks for the input.

If you look at the N/A engines in a specific torque comparison, the 4 valve (1.39 lb-ft/CI) does have ~15% advantage over the 2 valve (1.21 lb-ft/CI). The 4V is obviously a higher performance engine. The specific HP advantage comes from the higher revs and improved flow at high revs of the 4V. I would think that this would not be as big a factor on a FI engine.

Will adding a supercharger reduce the redline from the current 7500? I suppose we will see when the GT500 is introduced.

And Ti-VCT.

The ZL1 engine has variable intake and exhaust valve timing?

Any concerns whether the 5.2l spray bore block can handle the combustion pressure that would be generated by the level of boost necessary to produce such HP?

The Trinity motor did it fine to 662hp, and GT350 blocks seem to be handling it well.

I was told that cylinder wall thickness was something that needed to be addressed for this application. No doubt the block for this application has been gone through and been beefed up appropriately. It'll be interesting to see how they went about it.

I was referring to the Ford engines.

The new 5.0 block looks very stout. I would assume the 5.2 is also based off of this architecture. Not sure if [MENTION=10281]BmacIL[/MENTION] would have info on this or not.

I would concur that it's based off the Gen 3 Coyote architecture.

Conflicting info. Didn’t the leaked CAD images show a port injection only engine?

I truly hope it is Gen three.

The injectors are part of the head, it could still utilize the same block.

your a wealth of info 65T, thank you.


Not a question for you directly, but for all. What are the chances this car could come standard with a roll cage?
