How fast is a 6.1 conversion?

[autodynamics]

You should become a gold member and take advantage of our specials. We have a heads and cam package that adds 80-85 wheel horsepower and torque with a stock idle, 2-3 mpg improvement on the highway, and no loss of mileage due to idle. You won't know there is a cam in there by listening to it.

As far as mid 12's go, there are lots of variables that go into the ET that you run. If you give me the complete breakdown on your times, I.E 60ft, 1/8 ET & mph, and 1/4 ET & mph I can tell you what to do to improve your car.

What trans is in your car?

80-85 rwhp? Are those real numbers ?
And add 2/3 mpg? I gotta see that!
What are the specs for the cam you recommend ?
And what are done to the heads?
Do you port the intake?
What exhaust? Long tube or shorty headers?


I have no doubt cam and heads increase power but I gotta see it with my eyes,
When I was younger every vendor claims big power until its installed then your on your own.
Are there any cars in the ny tristate area I can see..

I will post my et times
I know my 60 ft was 1,82
My mph at the end was 107.7
And my et was 12.777
And one pass @ 12.6

we pickup 40/50 alone from the cam I am telling you about. That is on a STOCK 6.1 with stock exhaust and airbox. What was the DA on your runs? What does your car weigh? There is probably 1-2 tenths in your 60ft with the right setup. 107.7 is a really low MPH for a car that should be considerably lighter than an LX. I would say you are loosing a lot through the drivetrain. You could benefit from a dyno tune.

Car weighs 4130
Automatic 4l60
3.90 gears
Temp was 60degrees

What Dyno are you using?
Mustang dynos compared to others show different numbers.
I will post my track numbers

The new "hemi" is NOT a wedge combustion chamber. Please, as mentioned before, do some research. While it may not be a true hemi chamber, it actually is a form of a polyspherical type chamber. But it is closer to a hemi configuration than a wedge.

 

[snakeoil24]

LXmodguy sorry but you need to do research I have been running hemis since 1971. The later model motor is very nice don't get me wrong but it is a modified quench chamber for emissions it may have canted valves but it definitely is not what a Real hemi is. Sorry but do your eading and you will find out these two ribs on either side of the valve make it a Emissions legal Quench.

 

[snakeoil24]

I am happy we have what we do have but Chrysler was being run by mercedes and they still brought out a good motor. But a regular Hemi Combustion Chamber is really hard to get fuel efficient.

 

[autodynamics]

Honestly who really gives a **** if it's " real or whatever "
It's what there making now

Anyways let talk engine mods

 

[snakeoil24]

WileErobby I will show you a hemi Head made by Ford come down to Edison and take a look/.

 

[autodynamics]

Ok point noted!!!

Like I said what about power upgrades!!

what they heck did you do to get the car so heavy?

I would say that isn't all that far off from what it should run at 4100#. A converter and traction and you can shave .4 off your 1/4 mile times.

Let's take the mod conversation out of the thread. I am tired of arguing with guys that think their old hemi is the only hemi.

I love the old hemi. It was a great motor that was ahead of its time. It does me no good to sit here and argue with you. Why don't you file a petition with chrysler to have the "hemi" name taken off the new motors? You can argue why you believe its not a "REAL HEMI" for about 30 seconds before their lawyers and engineers shut you down.

 

[autodynamics]

Who cares new Hemi old Hemi whatever
I can't believe the argument or who cares for that matter

I have been researching cam and heads or if the price is close I would swap a 426 mopar all aluminum motor

If I go that route I can sell my 6.1
Recoupe some $$$
Cam and heads there is a lot of stuff out there but it's all in the combination
What cam and head package were you talking about?

My charger is a fat cat full of stereo equiptment a **** load of dynomat a/c
All steel.
One day if they make aluminum bumpers I would do that


Any suggestions
???

 

[snakeoil24]

Lxmodguy the after market should make a head for the motor to take advantage of the hemi Design. Then we would have a motor that would beat everything. The Quench chamber was designed for emissions.

 

[autodynamics]

Snakeoil24> why are you so hung up on the "real Hemi"
It's been noted what you have mentioned about the heads
WE GET IT !!!!!!

Now chill out

On low compression build we open the chamber up for a true hemisphere. The new hemi heads are 58cc. If you can tell me how to get a 2.14 and a 1.72 valve in a 58cc chamber I would be excited to learn. Meanwhile I will keep running my 400 cfm non-hemi heads. The aftermarket hasn't made a new head because with porting the stock casting perform exceptionally well.

That is cool. I wasn't knocking it, was just curious. It will cost you a LOT to build a gen3 426. I can build one for you if you want. Through a 4l60 you are looking at making about 500-525 to the wheels with a street friendly cam.

You can take the 6.1 and port the heads, intake, and put a very street friendly cam in it and make 430-450 at the tire. Do you have another 5000 to make a 426 out of it? You wont be getting money back for selling off your 6.1, You simply cant buy 6.1 blocks and heads as cores yet. blocks are about $1300 shipped and core heads are $1000-1500.

Cams are $500, if you send in your heads its $1900 for a CNC and springs and locators, the tune is $250 and that is an email tune assuming you have a predator to load the tune and you are using the factory ecm. So $2700 roughly if you can swap the parts. You will need a couple hundred in gaskets and such as well. So call it $3000 for 80 wheel horsepower with no change in reliability, idle quality, or driveability

 

[5.7 hemi]

Just to add to the "fire", my stock 5.7 with 6.1 injectors, log tube TTI headers with full exhaust (x pipe and flowmasters) runs like a scalded cat on a hot tin roof. Lxmodguy is gonna do my cam and heads for me this winter with tune and I look forward to having 400 or so hp at the wheels. It should run in the 12's around 105-110, fingers crossed on that. Bottom line is that these engines respond great to the mods that are out there and deliver reliability and docile enough for our grandma's to drive.

 

[lxmodguy]

I forget what magazine it was, but they took a truck motor out of a junk yard and bone stock with a single turbo they made 630 horsepower out of it. The new hemi's are for real. I have a friend with 1200 wheel horsepower out of a 6.1 motor. You can do an awful lot with them.

 

[kb67mopar]

Anybody know what a good cam for a stock 5.7 would be? I want a bit of a lump to it just to give it that evil sound and maybe a few extra ponies. This will be one of those things that I do down the road after I get the car drivable...but while I have all of the minds together?

Oh and for what its worth, I could give a rats a$$ whether or not its a complete hemi-sphere...its made by Mopar, has valves directly across from one another, looks like a hemi, and runs as good as one....seems to have enough characteristics to be worthy.

 

[5.7 hemi]

What kind of budget do you have? Lxmodguy can recommend a good one for ya and do the tuning, send him a pm and see what he has to say.
