How do you figure the whole hp/weight thing when some cars like ss/tc's can be making 50wtq over their whp? Like how does that play out in that whole process? Or do we just ignore those numbers? I know its ricey but just always wondered.

Like say a ss/tc and a civic weighed the same but the ss was making 330hp/370tq and the civic was making 380hp/280tq. Who would/should be faster from a dig and roll??

 

I never have compared the Mercedes AMG sedans and diesel cars when it comes to power to weight ratio so I can't comment on that.

The reason power/weight ratio can be used as a decent starting point from a roll is because we are comparing a FWD car to a RWD car in this case and racing from a dig obviously the RWD is better off (usually). And your comment regarding the disadvantage of weight from a roll that would apply more so to to a race with cars with the same power/weight ratio with one car being light with less horespower and the other being heavier with more horsepower.


Didn't mean to come across as cocky with the "I'm an Engineer Comment" however when you tell me basically that my prior post was garbage I will defend it. And for your information I am graduated and my background is in Structural Engineering & Petroleum Engineering but I am currently working Mechanical so I actually do know a thing or two about "power to weight, inertia, rolling mass, ect" probably more so than an engineering drop out (or someone who chanegd their major).

Thank you and please come again

 

^ all things being equal (mainly the actuall power curves are similar at their respective levels) i think the cobalt would win because horsepower is a figure of torque drawn out over time. to make things easy, torque is for getting off the line and horsepower is for pulling up at high mph. torque is how far you drag the wall when you hit it and horsepower is how fast you hit that wall.

If an idiot is pushing BS then I will say something which happens quite often here...

But I do agree 60-100 times would be awesome now that cars these days are much more comfortable and capable of 100+ mph!

Oh so I am owned now huh? I like how you say drop out, it is entirely different when you change majors. I just figured I want a good return on my investment long term and although Engineer salaries are great when you first graduate they level off where as an MBA from a good college can get you alot further (potentially, it's up to the person). It was simple mathmatics...

Of course that statement above becomes null and void if you start your own company as that just applies to someone who wants to work up through a large company. I do think though the two best combinations of people to start a business would be a Engineer and a Business graduate!

I don't think I will come again Ahmed, did you work a 7/11 while in school?

Being a Chrysler mechanic and a Mopar Fanatic, let me help you guys out. This race is going to be a drivers race. with that being said, it all depends on if the SRT driver knows how to race the car without wheelspin. even with the ESP on, you will still burn the tires on an SRT. It also depends on the year of the SRT because in 2008 they started puting LSDs in them and in 09 started puting 3.92 gears over the 3.06 gears, if this is a 3.92 car, you dont stand a chance from a dig. These cars are consistant in running 13.4 in the quarter, just consider yourself lucky it isnt an SRT Cherokee, youd loose bad.

You guys better enjoy beating SRTs now, cuz in 2011 when the 6.4L comes out, it wont be happening.

And also, you can only get a manual SRT in the Challenger.

 

First of all I never said your an idiot, and again you must of not read what I said "drop out (or someone who changed their major)" no matter how you look at it you dropped out of engineering and took soemthing else, not doubting that you have a post secondary education. And when did this turn into a salary debate? Also I don't know what makes you think my name is Ahmed, does my user name "tom.g" sort of not give it away that my name is Tom?

Next time just read someone’s entire post before automatically assuming it's worthless.

 

second time today, but ibtl i hope a vid gets posted of this. I'd like to see it.

 

Putting that "someone who changed their major" after dropped out in parenthesis shows sarcasm, and if you didn't mean it that way then don't put it in there. Remember it is really hard to show emotion behind a keyboard.

Never said I was an idiot, not sure where that came from.

Dropped out and changing majors are two different things, take it how you want but dropping out because you can't do something or changing it because it doesn't interest you is not the same. I was doing just fine when I changed.

The thank you come again statement is why I was asking if your name is Ahmed, ever see the Simpson's and Apu? Or half the other gas station marts in america, the saying kind of speaks for it self...

Not trying to make it a salary debate, just telling you why I changed and part of the reasoning behind it.

Again, not sure where you got worthless but never said that.

Are we clear on everything now?

Tyler

 

They are all auto, FAIL!

The real question should be from a dig or a 40 Roll, From a dig he is going to get you up to about 110. You might blow past after that.

From a roll you have him on lock for sure. SRT-8's are heavy and only make like 370WHP with those mods, and weigh well over 4K pounds.

From a roll Cobalt wins easy, from a dig, I say SRT-8 wins by a car.

 

UGH, I swear this forum's members think their so intelligent yet know nothing.

THERE IS NO SUCH THING AS A MANUAL SRT 8 300C.

I dont even think dodge has EVER made a manual SRT-8. Charger - Auto only, Challenger - Auto Only, Jeep - Auto Only, 300C - Auto Only, Magnum - Auto Only.

They are all heavy as hell and BIG. They are trying to be luxury muscle.

 

Im gunna say if the SRT is 07 or older, its gunna lose, 08 and up, SRT is going to win. Its a heavy car, but mercedes benz's driveline sure makes the car feel like it weighs half as much. If this thing has 3.92 gears, you dont stand a chance.

 

Are you talking about from a roll or from a dig? From a roll the SRT-8 does not stand a chance, unless its a 20. 40 roll and up the cobalt is going to yank it badly, given pookie can drive.

From a dig I think any SRT-8 300C would pull pookie. Whats the big diff between 06 and 08-10

 

the big diffence is gearing. with any RWD car, the gearing makes a world of diffence. You take a car with 425 hp and you only have 3.06 gear, you are going to have a tough time getting the car going from a roll. With 3.92, which are an option starting in 2008, you add almost a full rotation of the rear wheels, which means you can launch hard and start out hard. For example, a 2008 Dodge Challenger SRT8 with an auto and 3.06 gears had the gears changed to 3.55 gear ratio, the car gained almost a full second in the quarter mile with no other mods.

 

I know how gearing effects cars, I didn't know they changed gears between two years, 3.06 to 3.92 is a huge increase. I am not a big dodge fan and do not follow their stuff.

I would own an Auto GTO before I owned any dodge SRT-8, and I would never own an Auto GTO.

 

Thats fine. Everyone has their own tastes. I hate Mustangs.

 

i hate mustangs also

thats a real nice challenger by the way prnd3l

 

^ I like mustangs, what about the new 5.0? Can you say underrated...

I also agree that is a nice Challenger, is that the Plum Crazy color?

Tyler

 

Yeah, its one of 1200 in Plum Crazy. My buddy has a 68 AMX, they used to make them here in Kenosha, so they are everywhere during the summer. I think Mustangs are over rated. I do like the new 5.0 and their new V6. The new Chrysler V6 is going to be rated at just under 300 hp, now if the Challenger wasnt such a heavy car,it might compete, but they are too damned expensive. If i didnt work at the dealer i bought my Challenger from, id be driving a Camaro SS

 

Yes it would go down.

 

^ thank you cmiller8006 at least we agree on one thing. the mph will definitely go down. example: look at all the fully bolted ss/tc's on drags trapping in the 12's with lower trap speeds than fully bolted ss/tc's with street tires trapping 115mph or whatever and getting a low to mid 13.

 

Pat, did you guys ever race? I'm sort of assuming not seeing as how you didn't come out to the pike this weekend..

 

The fact holds true that the better the 60ft time the better my mph has always been. I have about 300 timeslips ranging from n/a, turbo, supercharged, and nitrous passes.

You may not think so because you're running slicks and getting traction that way. Slicks have been known to drop mph vs radials/drag radials.

 

no we didn't race. it wont happen until mid April. i did run a cts v tuned and intake ls6. took him 2-3 cars. don't know what kinda tune he had, be he said he paid 300. lol. i don't understand why the ls2 gto is so fast?

 

Dig or don't race at all.

 

For those arguing about trap speeds, ever wonder why? I'm thinking rolling resistance... Think how much more resistance a sticky DR has at 18 psi as opposed to a low profile street tire at 35! Want to do an easy test to put it in real terms for you? Take a wheelbarrow, and fill it up. Push it once with the tires filled up properly, how easy it is to push? Now deflated the tires to half that and try again..... Or shoot, just put your car in neutral and do the same test, once at 35 psi and another at 18. Its the same reason cars get so much worse gas mileage when tires are low!
