Can Chevy or Ford beat the Hellcat monster

[willhe64]

Pro stock is highly regulated, the parts are pretty much identical between makers, and they are nothing like the parts in a production engine.

3" cam lobes. 2.5:1 rockers. 4.7" bore and only 3.4" stroke to make 500 cubes.

Where I was going and I guess it wasn't clearly stated is the hemi in the hellcat is new and I'm wondering if that motor is more formidable than the
Coyote, the LS3, LT4 Etc.

Does it have the capability to put out more per cubic inch?

I mean theoretically Dodge could put it in a lighter chassis ala the Camaro and mustang and give us fits.

Well the hellcat motor uses a much larger 2.4L blower and a much stronger cast iron block, so, yes, its limits are higher for those two reasons. It is also heavier for those two reasons. Not to say you can't pull a lot of power out of the Ford or GM aluminum blocks but there is definitely more margin for error with a cast iron block.

Horsepower wise I don't see a F body getting that high. Gm doesn't like to step on Vette toes and GM is fine with the LT4's power as of now. I remember when they were testing the Z06 they said that more power was doable but 650 was on the edge of being controllable on a road course so they left it there. I think Ford's next GT500 will at least match the Hell Cats power. I think the next GT500 will be faster and if the 6th Gen hits its weight target a LT4 powered car will be just as fast or faster. Difference with the next GT500 and ZL1 is they will perform well in all measures of performance.

Not that it matters though since the Mustang and Camaro are pony cars vs the Challenger muscle car. Personally I look at them as being in a kinda different class. JMO though.

Camaro is more geared for the road course than drag strip. I don't see too many kitties on road courses beating the z/28 or zl1 stock vs. stock. Hellcat, if it can put the power down, is a drag strip monster and I would most certainly buy one...but the 6th gen is what I'm waiting for. We'll see what Chevy does...

Oh, and rayhawk, I like the way Al Bundy thinks, but not necessarily the dumb part though ;o)

Chevy could borrow the CTS-V's 640-hp setup for the ZL1 and narrow the gap considerably. 640-hp in a lighter platform could surprise. This is all considering Dodge doesn't turn the wick up a bit more.

Agreed, but the smart ones are a lot more work for sure.

Were all F'in spoiled at this point when it comes to HP/TQ..........LMAO

Stolen from FB , pulley and tune Hellcat.

Geez, my concerns or elation, depends on how you look at it. Lots of power for pulley change and tune.

Now there are two ways to look at it. The Hemi engine just is a monster or
Chrysler has put a fully modded monster on the street from the factory and engineered to last.

Man I wish Chevy would do that.

As I said before in the NHRA the GM factory motors seem to compete well with the Hemi no problem, so maybe its not the basic hemi design but the level of awesomeness the Chrysler engineers were allowed to put in the Hellcat monster.

I question that last part. Is it durable? Sure, it can handle the blast here and there, but will it be reliable with continued beatings?

The issue isn't with a warranty claim or warranty length. The jury is still out on the reliability of this beast. Warranty means nothing to me if I'm stranded out on the highway somewhere. If it does prove its worth, then Chrysler is on to something big and bad...and GM isn't going to chase it.

Hot Rod really was impressed with the Hellcat Engine

First off it seems to dyno around 650 to the wheels. That just an 8% loss from the cranks certified HP of 707. So the engine is probably putting out a lot more than 707 or Chrysler has found a way to make a more efficient power train.

Second I have now seen the Hennessy package for 800 hp and they don't do much to get it. Yeah I know, Hennessy always talks crank power, but another 100 HP with an ECU reprogram and a different throttle body. Seems like a lot.

Is the Hemi that much of a monster? Can we keep up with that thing?

Don't get me wrong I love all the muscle cars but I am running scared. I am soon getting ready to mod my baby but feel like I cant keep up.

Jim

For $60k turn-key off the showroom floor with a 5yr/100k warranty....is this a real question?

The answer is no.

Thanks for the article, very informative. A must read.

AS I said from the beginning, a supercharged Hemi combustion chamber is hard to beat, and after reading the article by 'Hot Rod' magazine (who did a wonderful job of explaining the engineering) Chevy and Ford have a tough challenge ahead of them.

Wow that blower flows 40% more air than the Z06 and with dual cooling loops actually retains the power lap after lap.

The cam is not that aggressive and much more power is available in that engine.

All this and 100,000 mile warrantee and for racing as well. That's confidence.

Now they didn't speak to weight and bulk, or I missed it, so it may be a bulkier, less compact design than GM's LS and LT engines. Time will tell on that one.


PS: Ford has always been known to pick up a challenge, but not sure the GM engineering team will be allowed to.
