Then fix your sig... which says your cherokee is your daily driver.

GF's car looks pretty nice, but seems like an opposite sleeper if it's pushing to only get into the 14's.


+1 on what S14unimog said as well. A 4k dump in those cars is just going to bog and stutter.... even slipping at 4k is a little low. Like he said, drop the 4wd and beef up the rear... you'd be fine with some nice tires at the right psi.

 

This thread is getting better.

And that vid of the XJ racing, I call BS. You never get a clear shot of the launch or start. Its a quick truck, I just think the cars are setups.

 

I have no idea how they launch, I'm a RWD guy and know RWD would work best.

wouldnt want to convert to 2wd bc its a 4x4 my girl and I share when there is salt on the roads and dont want to go out in the snow salt and ice with stangs.

Idea was to make the run, in 4x4. Cause the strap clamps, leafs and rusty shackles won't hold.

I'm probably going to scrap the idea, It's getting too serious. I got cars to go fast in. I wanted to pull it off in an XJ with just a few bolt ons and weight mods. Something completely not designed for what I intended to use it for...

Sounded good. But if its not possible to dump a launch in 4hi and drop it to 2wheel at 60 foot gear shift. I probably won't do it. Its not doing anything in 2 wheel without breaking something or getting traction.

I forsee wheel spin anyway. I got 2 open diffs. If i'm spinning lightly, I may not break TC

 

For Drag racing I honestly would go with an Automatic with manual shifter and a trans brake.
Nothing launches and shifts faster IMHO.

 

you should still fix your jeep, if it is really in the condition you say it is, then it should not be on the road at all. fix it right, before you hurt somebody.

 

an automatic with a transbrake is a joke to me in anything thats not running in the sub 9's.... imo

 

Brakes can be overpowered when just doing a brake stand launch... a trans brake allows you to hold the rpms right in the powerband with out worrying about creeping past the sensors.

However in a 4.0 the power is pretty much off idle so a trans brake shouldn't be necessary.

 

A higher stall torque converter will do just fine. No need for a trans brake on a street car/ part time racer.

 

I don't understand your statement... A high stall torque converter doesn't hold you at the line... A trans brake and torque converter has 2 different functions.

 

He is saying you don't need a trans brake with a high stall TC because the brakes should be able to hold it since it's not putting out a lot of tq yet. At least that's what I got from it

 

X2

It still kills me how some guy comes in stating hebuilt his girls stang, and his DD is some beast of a car.....

...yet he can't figure out how to launch his Jeep.

 

thats what i was wondering and i was also wondering why a "detune" on the gf's stang and have a intake and full exhaust just to take the power back out

 

put slicks in the rear in 2hi ive seen 500 hp cars dead hook. i can deadhook my 5 speed jeep on 31s like its my job, and yes its posi

 

I don't think i follow you.

I can launch my jeep. just fine. I'm not dumping money into new leafs, shackles, u joint swap. Would be ideal. but not practical. Would rather just launch in 4 wheel, as every other guy racing a truck does especially diesel.

Either way, I got other issues now, my top end power is gone, I never changed the fuel filter, plugs, or wires so I gotta see if I can get it back. Are crank sensors adjustable?

 

I think the main thing you are missing here is that taking a jeep to the track or even driving on the street with the problems you are stating it has, is irresponsible and unsafe.

Replace with junkyard parts if you can't afford new. Or just park it till you can fix it right.

And no, crank sensor is not adjustable
