Anyone on this site have a competitive pro touring charger???

[suntech]

Don´t get a headache here buddy, this is supposed to be fun!!! 

Honestly i believe that it is doable to get a charger to handle pretty damn good, using the right parts and setup !

[Mike DC]

                              
You can make almost anything handle tolerably well if you hack up enough parts and replace it with enough aftermarket parts.  I think it becomes a question of how much of the original car you want to retain in the process.  

By the time you've got a Charger that handles like a modern Corvette, it's probably gonna have a whole pile of modern Corvette components in it.  





If you're really ONLY after the looks of the old car and nothing else, then IMHO you might as well do one of these coversions we're seeing lately.  Get a modern 2006-2010 Charger undercarriage reskinned with a vintage Charger's outer body.  It's a lot fewer steps than trying to do it one piece at a time with a Pro Touring project.  

For my money it's no fun once the car is taken that far from its roots though.  Maybe understanable for a daily driver but not for a weekend cruiser. 

[suntech]

These conversions is nothing for me. It might sound kinda stupid to some, since you know that i am pretty much as far as you can get from a purist, but imo it kinda looses it´s soul, and to me it is not a 68 Charger anymore.......it is a 08 or whatever that is made to LOOK like a 68 Charger.
However i do like the aftermarket suspentions that are available, and whatever a creative mind can come up with on modifications, as long as it´s "tasteful" !

How much Corvette parts that is needed to make it handle like a Corvette?? Hmmmmm don´t know, but i will limit my corvette parts to LCA. Uprights will be custom billet ( ok........made for the C5), to lower the XV setup 1 inch, and still have correct UCA / LCA angles.

[thedodgeboys]

It's pretty much all been said already except service after the sale ( or during if your working with xv) is it in stock for example. A lot of xv's stuff is always on backorder, some of the quality is reduced on the cheaper on sale setups that the are offering I have seen an upper control arm fail with their stuff, the new solid arm is the one you want.
They don't make all the parts in house.

Lots of great info over at http://www.pro-touring.com/forum/

The altercation to my knowledge has had no failures   Bill makes all of his stuff and stands behind it.
www.bigblockdart.com

Bill will work with you as well if you want to buy it in sections as your budget allows so you can build as you go

I think the Xv stiffing stuff is the way to go or you can make your own I don't think anyone else offers a kit fo that
Yet.
That's what I did anyway on my challenger, good luck

I've decided not to go with a modern power plant.  It will loose too much of the character that I like.  I can't help smiling every time I turn the key and fire it up.  This would be completely lost on a modern engine.  I may fuel inject the motor, but we will see.  At the moment I am thinking alter-k-tion, or whatever it's called.  I like the easy adjustability of the suspension.  I'm not completely removing the idea of the hotchkis stuff, but I really don't liek the idea of messing with t-bars to dial in a setting.  However, once it is set up, it is solid.  I'm getting excited.  This uber expensive project is getting less expensive. 

I looked at the weight savings of going to an aluminum block.  150lbs.  Unfortunately for me it is not worth the 5k.  Especially when I already have a .030 over 440 in the car.  Aluminum heads will go on.

If you look at suspension in the same way as you do the engine, then the performance per dollar value of modified stock set ups is far and above what any aftermarket companies are offering.

Using the stock layout, it is entirely possible to create a car capable of handling to a degree to cover the capability of 98% over the drivers out there. So at that point, is it worth another $3-4k to get the car to the 99% level, or another $5k on top of that to get to the 99.5% level? I guess that depends. If you are a good enough driver and familiar enough with your car to notice the difference half a tank of gas can make, and use it an areas where changes need to be made quickly adn easily, then maybe you would benefit from a coil over set up. If not, then the stock stuff will work just fine. Now is the stock stuff perfect, no. Can it be tweaked to get pretty darn good, yes. And you don't have to buy $3000 worth of stuff from a supplier to get there if you know how to analyse the info and change it to get improvements.

Are AlterK and XV nice, yes. Are they lightweight, do they improve ride, handling, and provide adjustability,  yes. However, based on what I have seen and read on multiple sights that have been applied to multiple cars, the biggest amount of improvement these systems offer does not necessarily come from just the fact that they are lighter and more adjustable so much as they fact that their designers have already done all the research to know what springs rates complement what shock rates that are benefited by what sway bar rates. If you apply the same amount of analysis and research to the stock set up to optimize its rates, you can create the same level of performance. Lets be honest, a tire's contact patch could care less if it is a t-bar, coil spring, or leaf spring that is applying rate. It simply reacts to force, period.  Knowing the formula to optimize these rates combined with understanding the impact of changes to the geometric points within the system and balancing this all against a specific car's weight distribution and layout and how it will be for good or ill allows you to know what mods are beneficial and which are bunk.

Aside from a few drag racers, I'd be willing to bet that the vast majority of AlterK and XV buyers rarely go back and alter spring rates, shock rates, and ride settings once it is all dialed in. They set it and forget it. IMO,  the biggest advantages to using a coil over system is its ability to quickly change settings. If you aren't competing when your on different tracks under different conditions, is there any practical reason to actually use coil overs? Not that I can see.

[MedPhys]

Good point, and it's starting to push me towards the hotchkis setup.  I would be new to tracking this car,a dn thus the learnign curve would take a while.  I wouldn't be driving the car to the limit fo rsome time, thus negating the need for the high end stuff.  I could go the hotchkis route and decide if I really enjoy tracking this over a miata.  If I dedicde to pull the charger from track duty I would still have a nice street setup without the expense. 

How do the cars with stock geometry tweaked for the track feel on the street?  This was another reason for wanting an easily adjusable suspension; It can happily do duel duty with quick change to springs and shock adjsutment.

[MedPhys]

Just to add a little to the hotchkis setup.  I mentioned stewart development for revalved bilsteins earlier iirc.  Custom valved shocks to the setup would be  agood compliment.  Weigh the car, ride height, sway bar size, torsion bar, etc and get shocks custom valve to your setup.  bernie stewart builds custom penske stuff for the truck series.  Revalving the bilstiens is only $80/shock.

[Mike DC]

     
I wish we had more aluminum block options for Mopar V8s.  The 440 blocks are $5000 a pop and they don't even make a streetable alloy version of the LA-series smallblock.   

[motorcitydak]

If you cannot do any serious fab work, Id suggest that you get the Hotchkis stuff. I dunno about a Charger with their stuff, but check out the E Max Challenger they built. Get one of those tubular crossmembers and a better steering box. Add some big brakes and better wheels/tires then see what you come up with. Also, the new Hemi's are awesome motors. You can buy wiring harnesses and ECM's to get it runnin and im sure there are motor mounts out there too if you cannot fab up your own. That is pretty much the direction I was going to go until I decided on a Corvette C6 front end. They involve quite a bit more work but will be worth it in the end

[MedPhys]

Any big brake kits come recommended?  I want to do the 14"F and 13"R. Basically the biggest that I can get.

Well said. I truly believe the expensive aftermarket suspension stuff's most useful purpose is to impress others or make owners happy that they have "the" set up. A high percentage of drivers can achieve what they think they need much more inexpensively with just stock-style upgrades and better brakes. But, we all chart our own course.... that's what's so cool about this hobby.

[MedPhys]

Anyone make a kit cheaper that the wilwood kit for 14" rotors?  I think will be doing hotchkis suspension,chassis bracing, stewart development revalved bilsteins.

I'm from this school of thought too.  The aftermarket K's are good stuff but I think they are over the level of most people buying them.  The car owners are usually trying to fix problems that could have been done with less drastic work.  

IMHO the majority of guys complaining about wanting their front end tightened up would be content with some increased caster and a tighter power steering box.    

   

[HPP]

That's why I believe a vast amount of the improvement that is realized from the aftermarket kits is the improvement and matching of spring, sway, and shock rates. To calculate all of this for the stock suspension takes a pretty fair amount of calculations and more than a casual understanding of weight distribution and roll couple percentages.  However, you can get the stock stuff pretty darn close and optimized for the majority of most applications.

IMO, the biggest drawback to the stock t-bar set up is the lack of available rates to really dial things in to the gnats azz level. There are only 3 (4 if you search hard) possible handling t-bars rates that are easily available. Compare that to a coil spring that can be found from 400-1500# sets, and is available in 50 increments, and it is easy to see why a t-bar suspension would loose its edge in a serious competitive environment. However, very few of these cars in their stock form are being used in any serious sanctioned competition any more, so the point is probably moot.

[suntech]

I am not saying that you NEED the latest greatest most expansive stuff to get it good ride, but imo there is no doubt that a 3 or 4 link setup, with spiral springs gives a smoother better ride than leaf springs.
Front suspention same thing........... the T bars are hooked up way underneath the car, with the LCA tie in, and is way harder to dial in than a spiral spring setup. With spirals you have the opportunity to go with progressive springs, so you have a smooth ride on everyday gentle driving, and stiff enaugh for better handeling when you start to drive harder, and really compress them. I think maybe the biggest thing to do to increase handeling, is to loose noseweight...
I think the difference in the different suspention systems gets more noticable when you go with lower profile wheels.

[dangina]

if your starting to get into it and don't have alot of money - I'd go with the hotchkis setup, with a big brake kit and maybe a smaller block - stroked to get the weight down. You can do carbon hoods thats great - it will save the weight, you can also:

get aluminum brake master cylinder - claimed shaved 11 lbs.
aluminum big brake kit - shaved 30 lbs front, 20 lbs rear.
any of the aftermarket front independent susension kits - all claim savings of 100-150 lbs.
most guys I know that autoX with mopars that run the bigger brake 4 wheel disc setup run without a brake booster - saved 20 lbs.
go from a big block dodge to a small block (stock - without using aluminum heads or waterpump ect) - saved anywhere from 70-230 lbs depending on which engine you pick
achieving that 50-50 goal shouldn't be too hard to reach there is lots you can do to save weight...

I know from experience from friends that have bought the RMS alterk setup - that when they say bolt in, they mean it - talk about simple with no pain and if you can't weld - then this setup should be for you. I've heard bad things about the CAP setup on moparts, haven't heard anything on the magnumforce yet...

[MedPhys]

It's funny.....I put this car together 14 years ago while I was in high school.  My mother worked for a racing engine shop.  The engine builder tried like hell to get me to build a 400.  Oh no, I had to have a 440.  Imagine that,  a teenager that thinks he has it all figured out.    This isn't the first time I wished I had gone with a 400.  It would have saved some weight,  easily stroked, etc, etc.  I thnk there may be 20k on the motor that is in the car.  I'd hate to start over with a new build, but time will tell.

[NYCMille]

Tom Q is dead on when he says: "If you want a real competition car this is the wrong place and a charger is wayyyyy too big."

I've run my pro-touring Charger for 6 years on racetracks all over the country and while it does handle and stop well, it's simply too big and heavy to be competitive. Now, with that being said you can surprise some people higher dollar machines if you're a good driver. I've also found that you can do quite a bit with a good torsion bar set-up, good shocks, sway-bars and some chassis stiffening mods. The XV set up is nice but uber expensive and you'll see that NOBODY puts up any numbers in regards to what type of handling you're actually going to get for your money.

My - update the car with a few modern amenities like brakes, OD transmission and decent suspension and be done with it. Remember, these are 4000 lbs and 18 feet long... dimensions that are not conducive to road course work.

[bill440rt]

I simply couldn't afford the aftermarket big-buck suspension kits, so I upgraded stock:

Poly bushings, KYB shocks, bigger C-body tie rod sleeves (aluminum) and ends, aluminum strut rods, Hotchkis sway bars, heavy duty rear springs, Keisler auto OD, Steer-n-Gear Stage 2 PS box, and finally the Wilwood big 4-disc system coupled with a Hydroboost unit. Lots of aluminum on the engine too, helped with weight savings. And frame connectors.

There is a very noticeable difference in driving & handling, like night & day. Still spent a small fortune, though.

I totally agree with most of your comments here.  In the big picture the Charger is a pretty well designed production car that's just 20% too big for what we're trying to do with it.    

But to point out one thing, IMHO the XV Motorsports stuff is probably not going to be very suited to measuring the gains.  It seems designed to affect the "feel" of the car at least as much as the lap times or skidpad ratings.  Particularly their bigger deal with the aluminum K-frame and Vette front control arms & spindles, etc.  Another setup that produces comparable track numbers might still be far below what the XV stuff could offer in real world street conditions.  

[Tom Q]

Hey you guys...the B7 Charger in the pic is wearing 16x8 wheels with 255-50-ZR16 tires...do not let looks deceive you. FYI a 16x8 wheel with a 255-50-16 tire is very ideal in size fit and performance.

If you are insulted by the show poodle comment I cannot help you as that's the way it is...

I learned the 4 most important items to have on your handling car are:
16 inch wheels with sticky tires
Real seats & seat belts
Adjustable shocks
Brakes that don't fade away
Everything after that improves on the basics.

Even the stock suspension set up was limited by the tire and shock choice and the overall handling [think lap times] was severely handicapped by not being held firmly in the seat by a 5 pt seat belt.

I can't wait to hear about your first impressions of this thing on the track Tom.

I pretty much did the same!   The drives incredible for a big boat.  I wanted my car to be able to go on a track if need be, and I plan on doing it.  Not talking about racing or such, just seeing how it performs and having some good 'ol fashion fun.   If you want to make the car more competitive for racing, you need to reduce the weight A LOT.  Strip away....

This. The majority of guys are never gonna use the potential these systems offer - most guys would be better off upgrading the brakes, shocks, springs, torsion bars, sway bars and UCA's and a better steering box and putting the rest of their money into something else like engine upgrades ect..
