what makes the new hemi cars so fast - 01/15/14 09:18 PM

I have an srt8 challenger and my mom has a hemi 300 and i am just amazed how fast they are for a stock vehicle. I remember back when my 68 383 roadrunner was basically stock and this heavier car with smaller engine would eat it alive. every time i drive it i keep saying this thing cant be stock and i was curious is it the head flow they have now or is it the efficiency of new engines now or is it just a comination of many things

This pretty much sums it up. An engine is only an air pump. Pump MORE air, do it MORE efficiently, you make MORE power. Pretty basic.

Transmissions are also much better... Research the DCT transmissions. Automatics are now faster than standards!

Sometime in the 90's an issue of Hot Rod magazine I have was talking about fuel injection and computer control and what was about to happen next.

They went on to say that FI and elaborate engine control will open more doors for horsepower.

They also added that the old hp tricks like high compression and better flowing heads were soon to be used by the manufacturers.

Hot Rod was right.

Go ahead, have a look at the compression ratio on your SRT or the Three Hundred. Guys complain about getting these old girls to run on 9.5 to 1 and some of the new engines are 11 to 1.

I have a 5.7 in a Ram and I know what you are talking about. You wouldn't think a pick-up truck would be fast, but it is. I used my 1/8th mile time and it converts to 14.98 in the 1/4. A 4700 pound four-wheel drive brick.

Exactly...

Its like just the other day, I drove a friend of mine's late model AWD Infiniti G35.. Got it out on the highway and nailed it..WOW..the thing pulled like a freight train ..8K plus redline...Only 3.5 puny naturally aspirated litres pushing a loaded down 4000+ lb sedan.

Simply amazing this new stuff is..

My wifes 3.5 liter V6 Ford Edge "station wagon crossover thing" has 275HP and shifts at 6500, moves pretty good for a wagon SUV thing as well. It shifts at 6500 and the tach only goes to 7000. Makes you feel like your really hammering on it when you almost peg the tach.

Uh uh, 9's baby!

I have an SRT-8 too. I believe it is a combination of things, not just one. Ignition and fuel systems are light years ahead of the old stuff, add in variable cam timing, lightweight components, more gears in the trans, and the list goes on.

The one thing missing that the old big block cars had is TORQUE! You just don't have it like the big motors.

However, you can go to the track and rip off 12 and 13 second passes all day, then pull out the gate, turn on the A/C, set the cruise at 80, and knock down 20+ MPG in pretty comfy surroundings.

That is one of the things that appealed to me about my srt8 was the ability to go to the track and put down some decent numbers then just turn on the a/c and head home while getting 20 mpg. dont get me wrong i love my racecar but theres times i just enjoy going to the track without all the hassle of the race day stuff.

" Wallace shows 431 RWHP and 479 FHP. 112 mph @ 4257 curb weight. "

I remember reading an article when the gen3 came out. they dug out an old dyno sheet from 64/65 on the 426, and it made 476hp. they stripped a 5.7 to the old specs(no WP,PSP, etc) and it made 476hp at the same RPM. I want to say it was at 6800, but I may be off on that one.

Nothing that can't be done with the older stuff if your willing to start over and use EFI in the process.

Better flowing heads
Higher Static Compression
EFI
Better Cam Profiles
RPMs

All the same stuff that the imports have been doing for years Making 1.0-4.0L 4&6 bangers that fly and sip on gas doing it.

Those 5 are your primary factors. Several others as well but to a lesser extent.

Far as Racing them. Call Ray Barton and ask him. His brother is flying in Stock Class Racing.

I agree. I added EFI, gear vendors over drive and alterkation suspension to make my hemi car more like a modern car and it's so much more enjoyable then the old 60's tech.

Re: what makes the new hemi cars so fast - 01/17/14 01:11 AM

Another thing is how all the newer engines all run the same almost all the time. I mean with the the electronics if one SRT8 2013 car runs 12.90's almost all of the same model do. Back in the day the et's were all over the place. Car Craft claimed 13.10 @ 107 from a 70 Hemi Cuda but some mags could not get out of the 14's with them as they ran from a best of mid to low 13's to high 14's depending on the tune which was so important back then. I would say the average 1970 Hemi Cuda or Roadrunner ran high 13's to low 14's. But its embarrasing when some person restores one and has it so far out of tune it runs 15's. Put a new Hemi in the 70 Cuda and everyone of them most likey would run high 12's. But hey Hot Rod ran 12.60's in 63 with a 63 Max Wedge car and cheater slicks. Ron

Yup, Technology!
Take a look at the factory G3 heads. Very little short turn and incredible port speed! These factory heads will outperform ALL factory heads off of yesterday!
I will even say they outperform most small block casting that were offered by Mopar, don't know about the big block stuff.
They lack in the transmissions department. They still require a lot of hp to turn. If this new 8 speed ZF trans is as good as they say, 95% efficient, then the MPG gains should be substantial.
I love the New G3. 700 HP from 417 cid and a hydraulic with 11.5 comp. what's not to like. Matt

I think that's why I like the GT500's. A positive-displacement supercharger really wakes up the lower end of the torque curve. They feel as stout as a 440 down low. I've driven a Boss as well and didn't care for it... no torque whatsoever.

That's why I bought a GT500. Plenty of torque and efficient enough to make that much power and not get charged a gas guzzler tax.

This is why I put the ProCharger on my 6.1 HEMI. Now my SRT Challenger drives like a hot big block.

Nice! What year? I'm insanely jealous, especially if it's a '13 or '14.

Back to the original topic, the main advancement is in the cylinder heads. A 5.7 Hemi head, or a 5.4 4v Ford head, will flow over 300cfm on the intake, and the Ford will also flow 240+ on the exhaust, dead stock with no porting. They also have modern combustion chamber designs with a reasonable quench area and are made of aluminum to allow higher CR's without detonation on pump gas, which is where they have an advantage over something like the original 426 hemi head.

300/240 is better than the first tier of unported aftermarket aluminum heads for a BB Mopar, and completely blows away any set of stock 906's/452's/915's.

You know, I had just talked myself into the idea that a regular 300C was a good idea for my next car and that an SRT-8 wasn't necessary, so damn you.

Is it a 6.1 or 6.4?

aerodynamics also helps to get a better mpg and a higher mph.
would be interesting what you could get out of an old block like a 400
if you put heads with 4 or 5 valves on combined with a fuel injection.
never understood why the 4 valve hemi heads from covalt never made it.
that was "technology" for our old engines!

Re: what makes the new hemi cars so fast - 01/17/14 09:50 AM

You also have to consider that the new Challenger/Charger has at least 2-300 pounds on an older one.

My Challenger isn't much to write home about in 1st and 2nd gear, but hit 3rd you best be hanging on. It pulls like a freight train then.

If I can figure out how to finesse it of the starting line, I'm pretty sure it would run 105-108 easy enough. I've been 103 with it pointing the nose to the wall on the 3rd gear shift. Kinda makes you poop when you haven't even made the first payment yet.

I do kinda wish I would have gotten an auto/6.4. It would be a more pleasant experience at the track.

There has been a whole lot learned about how to present the fuel air mix to the combustion chamber. Swirl, tumble, fuel droplet size, crevice volume reduction, quench, plug placement. Add to that better valvetrain, big reduction in friction (narrow rings, windage ) more accurate machining(ring seal, head flow) better intake tuning and better exhaust systems. To add to the list, more rpms and narrower rpm range(more gears)

A friend of mine has got a 07 'cuda that used to have a 426 Hemi. I think it run 13's. A couple of years ago he switched it in to a 5.7 Hemi nad it run 12.6's. Now it has got a bone stock 6.1 SRT 8 with headers and has run 11.1 with 9" slicks.

There is also overall quality that has changed dramatically. Basically all todays production engines are "blueprinted" at the factory. The quality and tolerances of the muscle car era was pretty horrible.

I'm guessing his times are for a stock car, guys are even running low 12's with stock SRT's

I don't know which SRT's your referring to running low 14's, but even a stock 6.1 SRT is a low 13/high 12 car in good air.

Re: what makes the new hemi cars so fast - 01/18/14 03:37 PM

These are the forums I like to read. There is so much information just in the talking and sharing of what some think is general information but it’s not. This is the outcome of research and development, trial and error. The best part it was all done on Chrysler, Ford and GM’s dime. We are now lucky enough to get the opportunity to take all this put it in our older cars and really enjoy them. I know this all comes with a big price tag, if I get the opportunity to sell my 415 Indy small block I will most defiantly be purchasing a 6.1 or 6.4 motor and Trans and put it in my dart sport. How can you not want to do that? To be able to drive the car on a 40 degree day would be awesome. And not spend $8 dollars a gallon. I like it and please don’t hate the fact that a new Gen Hemi doesn’t look awesome between the frame rails of our older cars.

The 6 speed SRT's are a handful to launch. I was told on the Challenger board I would be lucky to get a mid-14 out of mine. I put it in the 13's on the second pass. It will literally go sideways in 3rd gear. 1st and 2nd will wheelhop like crazy too. Mine weighs 4540 w/me in it.

I have seen bone stock automatic 6.1's run low 13's all day long.

You can get a brand new 5.0 Mustang for under $30k, and it will run circles around that lard butted, over priced and underpowered Challenger all day... On any form of track racing.

It might as well be a 300C.

I'll keep my overweight '12 Challenger R/T. Bang for the buck is the Mustang.Look at the fit and finish on a Mustang.Cheaply made and the Interiors stink.I couldn't get comfortable in one.The Camaro is not any better.I could never get my left arm in a comfortable position no matter how I sat in it.Camaro is the worst of the 3 when it comes to blind spots.My best is 13.79@105 best bone stock 6 spd I'll keep it.

One word..."computer".

I've often wondered what Top Fuel cars could achieve with total computer control.

Exactlly! With out the Computer Controlling timing, and Ignition all the other improvements wouldn't be possible, nor as efficient.

My short list of cars was another GTO, a Mustang, or a Challenger. Goat was the first off the list. I looked at a Challenger sitting next to an'08 GT Mustang. I couldn't even get myself to open the door on the Mustang.

I have an 11 SRT challenger with the 6.4 and an auto. I have gone 12.82 so far @ 113 mph. It has a 3" catback and a cold air intake,nothing more. This car weighs 4175 lbs without driver and 3.06 rear gears. Soo it will not 60ft at all, best I've had is a 1.97. Put in a 3400 stall and a set of 3.92's and it should be a very low 12 second car. I work at a ford dealer and I know the coyote mustangs are quick but they are also 600 lbs. lighter.You decide. Most people that say they don't like the new challenger haven't driven one. :drive
the second video is in car on a 12.84 pass.

I love the looks of a new Challenger until I realize it weighs as much as a 4 door 300 or Charger. At least with a Charger the weight is justified and I would rather have a fast 4 door than an overweight porky Challenger.

2012 Charger SRT8 Super Bee. Bone stock + 275 drag radials (the ones you can actually daily drive with, not M/T's and a canned tune from Diablo)

= 11.92

The day Dodge sheds 500lbs from the Challenger and adds a Whipple to the 392 is the day I buy one.......instantly.

The lady of the household daily drives a 300C SRT8 rain sleet or snow and it rips for what it is. When it comes to value I think a used 300C SRT8 is very hard to beat. That is if you are looking for an American sedan with some bells and whistles. Aka great winter beater...way more comfortable than our old '76 Valiant 4-door with the 408/4-speed combo.

An SRT8 IS trimmed out a little nicer than most A-bodies .

The thing with these "new" muscle cars is they are so refined in how they deliver the performance as in no drama.

A retired GM tech buddy of mine was around when Tri power 427/435Hp 'Vettes were new and was finishing up when the ZO6 came out. He said both cars were capable of 150 MPH. The difference was that in 1967 it was a bellowing, both hands on the wheel, white knuckle, you best be paying attention to what you're doing assault on all your senses ride whereas the ZO6 was a slouched in the seat 1 hand on the wheel and listening to your favorite tunes on the CD cruise. Oh look Martha, we're doing a buck fifty. .

The wonders of modern technology.

Any Mopar guy who likes performance will surely agree with that as it would be a beast. Even an old fart like me knows that. Ron

You do realize a Challenger IS basically a 4 door Charger, right? The trunk is big enough to hold at least 2 dead bodies. LOL!

My '04 GTO was only about 300 or so pounds lighter and was a lot smaller car.

But yes, I do wish the Challenger was about 500# or so lighter. But then it wouldn't be so comfy to drive.

Dunno about the 500lbs though, maybe 150 but the car hasn't come out yet. 600-700 HP from the factory, 6.2L Hemi with a blower...aka "Hellcat"

Could this be a reality???

I might settle for 150lb weight reduction with that power level.

Re: what makes the new hemi cars so fast - 01/19/14 06:17 PM

So Glad I got mine when I did. They look and drive so nice. And with 500HP to the tires at 5psi it is wicked when the boost guage goes from vacume to boost. Plus it's getting better MPG to boot.
Even stock I would out run the junkstangs and junkmarows. Now I embarris them by womping it on them wile there WFO lmao. Even the local CTSV guy had to spend 10 grand to just stay even with my slow, heavy, boat. Lmao. He finally put some ET on my car when he went to 17" drag radials but I still run the same MPH he does. On BFG street T/As.
So everyone that can't afford one can keep bashing the only modern 2 door HEMI MoPars and ill keep showing them the tail lights.

Re: what makes the new hemi cars so fast - 01/19/14 06:39 PM

Prolly not but I would line up next to her to see
I also have a 01 camaro SS too but it don't stand a chance next to either. But it's fun to drive. It's a mid 8 in the 1/8th

Re: what makes the new hemi cars so fast - 01/19/14 06:42 PM

I really tried to get her to buy a Challenger. She almost bought an SRT8 Charger with all the bells and whistles. But in the end she loves her German stuff. An honestly the car impresses the heck out of me for a 5500lb luxury car.

It's reality, car will be shown in 2 or 3 months. For 2015 the Challenger is getting a new interior, new suspension, more power and refreshed exterior front and back, LED lighting.

Guys in this forum know about the Hellcat engine but aren't allowed to talk about it

That's what I am talking about! I considered one before I bought my AMG but when it was said and done, the Mercedes is a much better car all around!
