So I was picking up food at the local curbside Outback a few days ago. I pull up and the guy who comes out to give me my order seems interested in the Jeep. He says that he goes to some local street races where there is a guy with the same car and a "50 shot" that runs mid 9's according to him.
I said wow my car is nowhere near that, it has a few mods but nothing like that!
But later I thought about what he said and that would make that guys car very very fast right? I think I remember a few threads that talk about 10 seconds being pretty much the wall right?
Was just wondeing if anybody has really ran a sub 10, or was that guy just talking or maybe he was just repeating what the guy with the Jeep claimed.

Maybe in the 1/8 in Las Vegas with a 50 shot.

^^ haha thats what i was thinking it is probably 1/8 but a 9.0 converts to a 14.0

its probably a poser with a 4.7 or something :)

I am thinking someone this year will get into the 9 sec club... but if they are not on here, nor has it been posted about... It hasn't happened.

Typically I need to see the driver, the car, the timeslip AND a video for me to believe anyone's 1/4 mile claims. :rolleyes:

I dont see 9's being a reality until some major issues are either overcome or just aborted with stand-alone tuning and non-standard drivetrain parts. I also dont think a 9-second jeep would lend itself to being a streetable daily driver either.

hmmm, IMO there surely are some obstacles/variables out there currently, but i can assure you these obstacles WILL be overcome...and as for it still being a DD, i think this CAN be a reality...hoping time wont prove me wrong tho. lol

I think that the aerodynamics of the vehicle are the biggest obstacle to that, really. I haven't seen it yet tho I would love to, but hard to get past the fact that the Jeep is built like a brick :)

All thoses SSTB that do it are all 2WD DRIVE AND MODDED BIG TIME WITH LOWER GEARING AND SLICKS. There 4 wh drive like ours are 550 lbs lighter so you can imagin what the 2 wh drives are.

:worried::mecry:sorry....

I'm just saying it's not out of the realm of reality. Several member are already trying 2wd mods and weight reduction is not crazy out of the question. The brick factor shouldn't be the factor because the silouettes are very simular. The goal is obtainable. Just need the stamps to make it happen. :cool: So I won't be doing it but some other guys here can.

9's are possible and still have a daily driver. My Jeep is a daily driver and drives like a stock Jeep until I go into boost. Thats the big advantage of having turbos. I posted a run we made on a test and tune night a few weeks ago. The facts HP around 800 AWD on 13pds and a 75 shot of NOS to get out of the hole. We broke the input shaft on the trans just after the 1/8. The 60 ft was 1.59, 1/8 6.5@111 and the 1/4 mile time of 10.7@103. So if one of you guys with the ET calculator can run those numbers, I believe it would have been a low 10 or high 9. We were only testing so we did not run on high boost and did not have as good a 60ft as Bradenton (1.48).

The TBSS is completely different... all the 9-second passes are essentially LS-X blocked stand-alones with a myriad of tried-and-tested transmissions and rear ends behind them. They don't have nearly the issues we have, and the software to perfectly tune them as well as support alternative systmes like fuel and spark have been out for decades. They put an already-proven 9-second powertrain from either a vette/camaro/etc into the TBSS and now you've got a 9-second TBSS. If Chrysler had the GEN III Hemi and all of its predesessors for the last 30 years for aftermarket tuners to play with, we'd have a lot more options too.

The 4700lb weight of the SRT8 and the stock wimpy drivetrain that was originally designed to handle 425hp makes me think that 9-second ride is a pipedream that, although achievable, isn't something that will be consistent with "streetable" vehicles. You just can't stuff 1200-1500 horsepower through a transfer case like that, you NEED viable alternatives... the same could be said for the 5-speed, its only a matter of time before the limits of the NAG-1 in its current iteration of aftermarket beef-up is met. The front and rear ends are a sad joke when it comes to big 9-second horsepower numbers. The 20" wheels are a stupid idea to try and get into the 9's, and so are the low-profile tires. This isn't a Supra...1000hp doesn't get us 9.50's @ 149mph. What is needed to consistently achieve 9's is the same thing the TBSS's have... and thats very strong parts, big fat slicks, and perfect tuning with no interfearence from other players on the BUS.

everything would definitely have to be perfect for sustainable 9 second runs... drop every ounce you can...

there is a big difference between a 850-1000 horsepower supra or GT500 and a jeep... weight and aerodynamics alone are going to be half of a second... not alone (as stated above) the drivetrain problems...

If I'm correct, the TBSS in the 9's are purpose built. I have seen photos of them and they are gutted, modded and built only for the 1/4. We are still trying to run ours with full trim and be a DD. Maybe its time to find a wrecked one and build one like the TBSS guys have done.

think i have to agree with what Chris is saying here...with a proper TT set up, assuming the driveline components are built to handle 1100+ hp/tq, 9's are definitely possible at the same time maintaining DD status. Really comes down to controlling the boost. Once you have the boost under control and a SOLID driveline, it's time to slide into the 9's ;)

Its less of a car and its easier to convert to raceish set up. Less electronic workaround too. You could make an 8 second car out of it and I still wouldn't want an friggin ENVOY. The lowerered and race set up cars look mean, but its still an Envoy...

supabusa
04-27-2010, 04:53 PM
I don't disagree that alot of things have to be changed to run 9's consistantly. Maybe even change the driveline to 2wd. However, I've never seen a single 9 sec. car that keeps all of the factory componants. There maybe a hand full of course but not the norm. There are some Dodge cars that have been tested and proven 9 sec. rides. Maybe utilize there driveline. The Hemi platform will make the required power but, like said before, getting it to the ground is the issue.
It wouldn't hurt my feelings to see someone back a Jeep off the trailer and run 9's, never seeing the highway. I just want to see one of our beasts break that barrier.

Chris@LPM
04-27-2010, 06:01 PM
I believe 9's can be had with 850 to 900 AWD HP. The big help comes from the new wheel and tire combo. 1.4X 60' will make it easier to obtain the lower ET without needing more power.

I think we just need to take the front axel out of the equation and go with a true racing rear-end setup... either get rid of the t-case and run a LX-style rear housing on the NAG-1, or figure out a way to make the output shaft handle the power required to hook big slicks in the back and turn off every stinking function that the FDCM does. If you can put every ounce of 1000hp to the ground, its certainly possible... the sad thing is that it becomes less and less of a "jeep" every time you make a fundamental change. A 9-second car is certainly a wheel-stander, you're not in "typical street vehicle" territory anymore when it comes to the raw power being made, or the danger you have in losing control of something that picks the two front wheels up for half a second.

NA will be quite the accomplishment. Obviously your going about it the right way. IMO Starting with planting the power to the ground and eliminating some of the driveline power loss. Then it's simply weight and power.

as weird as it sounds you could go shorter like maybe a 26" slick and it would simulate having roughly 4.16's instead of 3.73's... and since the 5th gear in the jeep is so close to 4th you could actually hit it...

just a thought... but you wouldn't want to hit 5th within 200 or so feet of the traps

I have 28 1/2 305 Mickey Thompsons. I also have 4 245's on 18" winter
rims which calculate to about 4.20 gear ratio. They are alittle narrow but
will give them a shot sinse I already have them. I wouldnt hit 5th with my current

They have been having the most success with 3.92's from what I have seen.
They come 3.06 stock so they really need the smaller rear tire.
