Jeep SRT8 quicker?

[lieu910]

Not trying to split hairs, but my dealer was trying to convince me that a Jeep SRT8 is quicker down the 1/4 than the LX's.

I know they can get out of the hole quicker, but I don't see them being quicker in the 1/4.

Discussion.

[the hurse]

they are..........they are supposedly the quickest SRT-8 model, aside from the viper srt-10.

jeep srt-8 = 5.2 seconds to 60 mph, 13.5 seconds in the quarter-mile.

charger srt-8 = 5.4 0-to-60 time while taking 13.5 seconds to clear the quarter-mile at 105 mph.

"edmunds numbers"

ok well now that i read my own post, it doesnt really prove anything.........{{{sigh}}} ..............i'll just wait for the smarter people here to chime in.

No, your right, 0-60 goes to the Jeep, but not the 1/4 mile. Dont use mag times guys, use reality. All SRT-8s are faster than the mags allow. Ive yet to see any Jeeps tap 12s, while we have a good number of LXs that have.

The same AWD that allows that awesone hole shot creates parasitic losses once you get past 60, which the LX does not have.

Id call avergae times for a Charger SRT-8 about 13.2ish. While the Jeep will be around .4 or .5

Feel free to surface times to disprove this, but thats not likely.

The actual track times of these vehicles show all the LX's are quicker and faster through the 1/4 than the Jeep. The 0-60 runs depend on track prep for the LX's, not AWD, but my Magnum has run a 4.3 0-60 (calculated from a website) on a 1.97 60ft/ 13.15@105 pass.

Couldn't have said it better. Not only does powertrain loss factor in, but so does a heavier vehicle (if you thought the LX was a heavy pig........)

That being said, I think the Jeep is awesome, and I wouldn't want to race it light to light. Quite frankly, I tried to buy one but the markups (only a month ago) were horrendous on the Jeep and I wouldn't pay it. They must be coming off the line slowly, because I've yet to see one in person in the MD/DC/VA area.

They are quicker. SRT Engineers mentioned this during a recent online session. It is due to the gearing. The discussion did not outline 0-60 or 1/4 mile, so take this whichever way you want.

IMO they would be quicker in the 1/4 due to AWD hookup while the LX SRT8's will have trouble gaining traction on a WOT launch.

[glhs837]

That AWD becomes a hinderance after that launch. Once you get to where you can go WOT with no slip, your putting more power down. If you could never go WOT, then the Jeep would get you. But after say 60, the LX SRT-8 puts all 370ish down. The Jeep never puts that down. Before that, the Jeep is putting whatever they do, say 350. But never more. so, once that first push is done, its 350 vs 370.

Trust me, I'm pretty familiar with this, since the stock SRT-4s main competitor is the AWD WRx, same crank power, but 3-4 lower traps and abour .3 or so slower in the 1/4, modded, its the STi and Evo, both AWD cars. AWD cars usually have lower traps than you would expect for this reason.

Not sure what the gearing diff is, but glhs is correct. I currently own an AWD sedan (G35X) and the same concept applies. AWD is great off the line, and awesome in bad weather. Bottom line is RWD usually wins in the 1/4 race, mod for mod, due to the advantages mentioned above. With the G, I'd take any any RWD G light to light, but in the 1/4, they prevail. Same with these cars. The Jeep is very heavy (4800 lbs if I'm not mistaken), and weight is VERY important. Couple that with drivetrain loss, and I'd feel confident running against the Jeep on the dragstrip. I love both these platforms for different reasons, but the LX is faster/quicker with any room..........

Too bad with the Jeep SRT-8 there can't be a magical driver to drop it to 12.5 while everyone else stays in the 13's. Get a Supercharged Jeep man that would be wicked with the AWD.

Not sure at all what you're saying. BTW, I'm in the 10 sec F-body club. What are you running?

Oh about 1 stray Jeep hitting a super low ET while all the others are 4 sec behind while the 1 is "stone stock" like the rest. (poking fun at the super fast 300C SRT-8)

I have only been to the track twice. First time was crappy, I sucked bad... second time was no track prep, spun worse than on the street! Anyways, around Sept I will have new wheels with Drag Radials and I will see what I pull off, if my rear-end don't break. I hope to be putting down 450 rwhp NA next month. I may make it into the 11's if I hook. On street tires w/ no traction till 3rd gear I pulled a 13 @ 113. First run of the night, after that my clutch went and will have a new clutch soon. Is yours a Manual? PM me.

Mine was (sold) an auto with a converter and heads/cam. I only made 415 rwhp, but had it set up right. As a MT, your biggest issue will be the 60'. I was cutting 1.48 to get into the tens. You'll have the power, but MT cars are a lot harder to launch. Borrow some slicks once you get your car set up. And yes, your rear will be in serious danger (I fried mine and put in a Strange 12 bolt). Good luck.
