1997 GTP vs 2004 HEMI Ram

[MoshimoGTP]

Today i've smoked a 2004 HEMI RAM on the highway. We started from 0 mph. At 90 or 95mph i smoked the RAM by a two cars distance. How many HP the Hemi makes?. My car has stock SC pulley, removed TB Screen, removed U-Bend, autolite 104's and Custom Air Intake.

Thanks

Unless i'm mistaken, i believe the 5.7L HEMI put out 345 hp.

I tried to take one in my probe... that wasn't happening.. haha.

Well remember that that makes the car great is not only the hp is the hp/torque mix. HP basically measures how quick you can get there. Torque means how much you can get there.
Check the jap imports. A lot of them have a great hp rating but really small torque. Meaning that these cars are really subject to weight. Anything that changes inside the car would make it behave differently. On the other hand a car that has a massive torque would be less prone to behavioural changes when different loads are applied to it.

To be honest, the Hemi did not had a good driver. The thing has too much torque and too much hp for you to beat it. That is my humble understanding.

They weigh 4850 pounds without driver and gas, they are heavy beasts and thats the regular cab shortbox. Well over 5000 pounds fully loaded, they run low to mid 15's in the quarter mile.

Easily beatable by a stock GP.

[kilroypr]

Yes, but he was talking about high speed. Not racing from light to light. What is the RAM final gear ratio? If the Grand Prix has 2.93 stock and the RAM has higher than that then is easy to beat but if not then we have to check . Packrat by anychance do you have the final gear ratio?
Because at above 90mph the momentum would help the RAM get better acceleration than the GP because of it's massive weight and the RAM has good torque and good HP. THe only thing above 90 stoping would be a really high end gear ratio or a really really bad driver.
Is like normal big cars, they tend to be slower from 0-60 than smaller cars but if the have the correct final gear ratio and good torque/hp mix on high gear is a complete different story.

[packrat68]

Weight at high speed dosent change... it still has to make all that weight go faster. The gears ratios vary truck to truck but I do beleive that my buddys is a 3.55 ratio (four door rams have different ones than the regular cab) but with the weight the ram has to pull and the brick like arodynamics of the ram, the gp still has an advantage.

[kilroypr]

Well aerodynamic wise you are correct, the GP has an advantage(Dont get me wrong, I drive one) but the grater the momentum the easier to move a body. Momentum=Weightxspeed. So the higher the speed or the weight the higher the momentum. So the aerodinamics play a role but at that speed it is a heck lot easier for the HEMI to push the truck forwards with the torque/hp that it packs.
355 is rather high gear ratio. That could be the reason that at 95 our friend here smoked it good. The higher the gear ratio the lower the top speed

[QuiksilverGT]

my old man's got a chevy silverado SS that puts out 345 & 380 and my slightly mod'd GT burned his ass on the line but by time I hit 100 he was right next to me. the thing you have to look at is HP/LB my gt gets .0588 hp/lb where my dads pickup gets .0539 though they seem evenly matched heres where aerodynamics comes into play ( as stated by kilroypr) I dont have the stats but I can guarentee that the ram or in this case my dads silverado creates twice as much drag as our grand prix's

kilroypr I believe you are mistaken on this one. To sustain a constant speed once it gets there you are correct - the object with more mass would require less power to maintain that speed (momentum) given frictional forces are the same. In this case we are accelerating an object (wether 0-60 or 60-100 you are still accelerating), so the formula Force=Mass x Acceleration would apply. So the more massive object (HEMI Ram) would require more force to accelerate at the same rate as the lesser mass object (GTP) - again given frictional forces are equal.

FWIW

[i3o2Matt]

actually...if u think about it...the HEMI might probably has more friction because it probably has wider tires...but that'z prolly not that much more, therefore not that noticeable...just a couple centz from me...

[titleist312]

this 1 is easy.. im a truck driver and have a freightliner with 600hp and close to 2000ftlbs of torque and beleive me it has no chance against my measily 260hp 04 ws6 i dont care at what speed. Plain and simple weight is an issue at any speed, sorry kilro.

[titleist312]

by the way mopar is using the word hemi as a sales gimmick. the 5.7 is no where near a hemispherical(is that spelled right?) design.

[Ripn12s]

Titleist, you take the 04 to the track yet

april 18th. There was suppose to be a gtp car club clash that weekend but noticed it is no longer on the schedule but in october it will be the gtps against the t-bird sc. thing. when my car was bone stock we ran my buddys g-tech pro on a 45 deg. night and ran 3 consecutive 14.50s @ 97mph. 0-60 6.4 to 6.6. i now have custom exaust on the car and actually did notice a difference as the car now keeps pulling after shifting into 2nd gear.

04 ws6? sorry but they haven't made a ws6 since 02. Do you mean GTP? Because the hp you gave sounds about right for teh comp G/GTP.
