[Dr. Dyno]

Welcome to the board. If you're thinking about performance upgrades, take a look around my site:

Once you get started you won't know when to stop. My mod fever's incurable.

OOOH men , i saw all the MODS that you made for your cherokee i also saw the difference in the 1/4 mile , 15.1 i believe it was that of a 16.3 stock, well men , thank you

 

[Andru_PR]

Its not a sig. he just pasted his sig from JU in.

 

[Dr. Dyno]

Its not a sig. he just pasted his sig from JU in.

That's right. I cheated by copying and pasting my sig. from the JU forum.
I hope I'll be able to improve on my 14.61 ET pretty soon and get down into the low 14's. I'm nearing 4000 miles on my stroker and it seems to be stronger since I converted from 20W-50 dino oil to Mobil 1 0W-40 synthetic at the last oil change.
I'm also on the lookout for an NP242 transfer case to swap into my XJ. It has a full-time 4WD mode so I'll be able to launch hard without getting time-robbing wheelspin.

you XJ is 4WD ? what ET you did with stock motor ?

 

[Dr. Dyno]

I have the NP231 transfer case so it's part-time 4WD. To launch from a standing start on dry pavement, I have to keep it in 2WD otherwise my TC will be reduced to shrapnel.
When my Jeep was bone stock some 9 years ago, my 1/4 mile ET was 16.31 @ 84.9 so I've gained 1.7secs and 10mph.

 

[Andru_PR]

ooh ok hehe

 

[Andru_PR]

My XJ is 4 speed automatic , how recommend me to run it in the 1/4 in Drive or starting in 1st gear ?

 

[PstrKd4BrthCntrll]

I just kept mine[93 4dr 4.0L] in drive and let it shift thru the gears it self. It shifted into second just before redline[6K?]. Kept it floored, that basically all ya can do with a auto... Ran 16.6 was me fastest time...

 

[Andru_PR]

ooh man that was a good time 16.6 in D , ok i will test my baby in the 2 ways , thanks for the tip

 

[Andru_PR]

Dr.Dyno wich is the measure of your intake ? please tell me in inches

 

[Dr. Dyno]

I have a cone filter mounted on a 3" diameter PVC airpipe. From there I have 3" diameter corrugated rubber tubing to the TB. The TB itself is a heavily modified '86-'93 Mustang 65mm unit that's mounted to the intake manifold with a 62mm bored TB spacer sandwiched in between.
The throttle response is fantastic. With less than 1/4 throttle the Jeep just flies and accelerates to 110mph with ridiculous ease.

ooh ok
