Are you sure your not hitting the speed limiter? Mopar PCM gets rid of the limit.

The current chip installed by dodge makes the speed limit 110 mph. Jet chips have also said they can not change this limit. I would likt know what needs to be done to bypass this 110 mph limit.

As far as I know the Mopar Performance Chip (aftermarket thru dodge) has no limit. Members of another club have tested this to be true

YOu must have the same year Mopar PCM with the same year truck. Late models require VIN and mileage encoding by a DiamlerChrysler franchised dealer. The motors do vary slighty year to year. Guranteed the Mopar PCM will remove the speed limiter but I dont see a stock durango doing much over 110. Your problem might be the truck is drag limited ( not enough hp to push it through the air anymore)

Thumbs down

The limiter was put on because of the speed restriction of the tires supplied with the truck. I called Mopar Performance and they agreed that the PCM removes the limiter. As for going beyond 110 mph, drag is certainly a factor. Honestly though, going faster than that with stock suspension and tires would be suicidal.

110 is dang fast in an SUV. Just think of the fastest production SUV...Mercedes ML55 AMG, two magazines have tested it to 141mph! Not as "quick" as a Typhoon but certainly more top end.

Thumbs up

R/T Eater - you're right. I have driven an ML55 (rich friend's), unbelievably fast and nice too (although it's too small and can't tow my boat). That truck (Typhoon too) is engineered to go fast, it has the tires suspension and has been dropped. It's much lighter than the Durango too. I've taken my SUV to 170 Kms/hr (about 106 Mph), and that's plenty. Really smooth with the R/T suspension and bigger tires, but still, when I need to go real fast I'll take the sportscar.

all this seems to be true. but I have also changed the intake to cold air. i changed the headers, and i also added a flowmaster 40 catback system, The suspension on the R/T is not the same as the the SLT and sport durango, With the R/T you get very limeted body roll. If you have driven you will understand, I talked to a performance shop at the LV motor speedway they seem to think if i add a turbo it will push 450 hp at 500 fp of torque, also the drive shaft might not be strong enough to hanlde the pwr. But the R/T tike the Typhon is all wheel drive. I am not looking to get much past 110 mph but i want to get to the end of the 1/4 mile faster, and in doing that you need to be going faster then 110 mph....

Actually the durango is 4WD not AWD. There is a difference. The syclone/typhoon AWD system came from the Astro Safari AWD. I used to have a 91 Syclone, it was the best truck i've ever owned and hope to get another one someday, but it always has 25% of the power to each wheel at all times. The % of power to each wheel varies in full time 4WD. Not sure on the magagzine but one in Europe tested a stock one at 13.6 bone stock. Car and driver ran one against a Ferrari 348ts and it put it to shame by like 3 tenths in the 1/4. After 10 years its still the most respected truck around. Even a new lightning can't touch one in the 1/8 and if i'm not mistaken i'd put my money on a syclone in the 1/4 too.

don't ever confuse the durango with the durango R/T, the R/T has the same awd system as the Jeep charokee has in it and comes standard on the R/T only go to this site for all the information on the R/Thttp://caranddriver.com/xp/Caranddriver/roadtests/2000/September/200009_roadtest_dodge_durangort.xml

but unless you are already aware of it the only difference between an SLT and an R/T is suspension, wheels, and badges. The engine and drive system are identical. Chrysler wouldn't reengineer the entire drivetrain just to put an AWD system in it without raising the price a lot more than it is. It would be like Chevy producing the syclone and putting in an awd system without puttin on a mitsubishi turbo, differenent fuel injection set up and lowering the compression. Plus the Syclone and Typhoon have the same tranny as the 91 corvettes. Granted the R/T look better and handle better but under the hood and drivetrain are the same as an 4WD SLT

If i'm not mistaken I was led to believe your truck has 3.92's not 3.91's. For 50hp I would guess a very mild blower or a ton of bolt ons...50hp is quite a bit. Not something you can get from just intake, PCM, and exhaust. I know cat back's dont do much for R/T's cause dynomax is the contracted muffler supplier for R/T's. I'm not doubting you just curious what all you got done, how did you get that horsepower figure?

your right my bad its a 3.92. I do not have Dynomax Exhaust I have a flowmaster system, with K&N intake. you cant put the R/T on a dyno....k&n gives you 4% increase and 4% of 250 is 10 hp increase, now we have 260 now, tubular headers gives you on avg: 27 hp & adding the cat back system another 25 hp. there is your 50 hp increase..... you can go here to test a beta version of there online dyno you tell them what you got and they give you an estimate http://www.martelbros.com/

JET Computer Chips (+6%) + 14.7 hp
Edelbrock Cat-Back Exhaust (+9%) + 20.8 hp
Edelbrock Tubular Headers (+9%) + 22.1 hp
K&N Air Filters (+8%) + 19.6 hp

Total HP increase over stock + 77.2 hp
Total HP after modifications 322.2 hp

i can tell all those figures are from the manufacturer. I dont' think 19hp from a K&N is reasonable. If 77hp was that easy I'm doin it all wrong. You can't go by what the manufacturer says. For one thing I bet the factory muffler you had on provided just as exhaust flow as the edlebrock you replaced it with. And computer chips dont usually increase hp much. A mopar PCm will cause it is more than just a chip. A chip will maybe give you 5-10hp at the most but should incease your tranny oil line pressure to give you better shifts. I'd say all the mods would give you around an additional 30-35hp. Stock R/Ts dyno around 190-195 rear wheel hp. I bet you are putting around 215 to the wheels.

were did they Dyno the r/t @ all the places around here can not test on the real Dyno due to the awd system, I did not put the edle brock exhust i instaled all flowmaster but the site did not have flowmaster as and option so i went with what they had as a refrence, chips on avg give 10 to 20 hp you get most hp increase by changing engine parts, letting the engine breathe will greatly change that number.

Dude its like this...R/T dakota's dyno 190-195. Your truck has more drivetrain so it will loose more on the dyno. ALL R/T's (dakota and durango) from the factory have dynomax mufflers, so they already have a good system. I guarantee you, you won't get 77hp from those mods. You just can't say oh well this one gives me 6%...that is what the manufacturer will tell you. Trust me my brother works for Mopar and tests thier performance product line. If you want 77hp increase the only way to go is either a supercharger or a little shot of nitrous

besides there is no way to test your "300" crank shaft horsepower.

one other thing...77hp is roughly 1/3 the hp of the motor. Your not gonna get 1/3 the power the motor makes with just "makin it breath better".

300-315hp is achievable with the 5.9L 360. However,it takes the Mopar Performance camshaft,intake manifold,cold air intake,pcm,heads,headers. A really good aftermarket dual exhaust system, underdrive pulleys,and a bored throttle body from Flowmetrics,etc.

Default Dyno?

You may be able to remove the front driveshaft to run on a dyno.

On the manufacture subject>
They tend to advertise "peak power" in their claims.
A better compairson would be if the were to advertise an average gain over the usable power range of the motor.

And at what expense is their HP if it loses lowend torque? None! But they would advetise that? No.
A gain of 20 HP at 4500RPM would not be as good as an investment at a gain of 6-10lbs/ft of torque from 1500-3000RPM especially as heavy as the Durango is with full time 4WD.

My mods the cold air made the biggest difference and the TB helped only from 3500 up to 4800. The muffler made no difference at all and that was done last. Butt dyno of course. Hope to get back to the track this year. I have a base line and want to know what my mods gave me. I thought after opening up the intake with the cold air and TB that the stock "restrictive" muffler I got rid of would have also made a difference. Boy was I wrong. Anyways it sounds better.

Just my .02
