what exactly do you mean by 'could be master cylinder'?
im positive that it is adequate, since my jeep is a 97+ which come with the same master as disk brake GCs. so bigger heavier rig with 4wd and four wheel disk use the same master, so Im sure its more than enough for mine. since mine is even lighter than stock, and still on small (relative) tires

thats at the limiter, which is about 120...(117ish)
I cant wait to get the new computer to take care of all my hiccups.
the little orange just likes me to get out and check to make sure the engine is still there....Im running a manual shifter in Jeep so the TCU gets all upset at me.

Good friend of mine is on 35's and changed out his gearing from 4.10 to 4.56 and says he is getting 17 mpg's. His is a 97 with no modifications for better mpg's. Mine on the other hand will get a 99 intake, new headers and exhaust, new gears to 4.56 running 33's. It already had a tune up, oil changed, new cooling and cold air intake. I am running 15 mpg's and am hoping for near 20, but we will see.

yea, as you guys can see from my last pic, its hard for me to drive 'efficiently' the only time im able to 26-27 mpgs is if im just cruising at about 55 with the converter locked in OD. The last time I did this I had a pregnant chick with me, so I had to behave the entire day. (Dont worry, her BF doesnt 'think' its mine)
with normal driving Im at about 24-25, which includes some shenanigans, with a little aggressive and/or city driving im at 20-22. and when I spend the day picking on ricers Im at 20. If Im hard on her like she likes it, then Im down in the 15-17 range, and if I got a play date, Ill get as low as 5-8.
so I got a nice little range of 5-27mpgs...but my average day to day number is consistently 22-24 which is a nice mix of everything.

LOL, Im a CAR guy, so I appreciate all cars. Everybody has made some good ones, and everyone has made some bad ones. I just like having things that are a bit different and people dont expect
I used the ZJ rear cables, and ran them to the factory XJ 'junction'. The little box on the frame rail where the 2 join together. then I just joined them to the stock xj cable.

before you jump the gun, there is probably a discrepancy in your communication.
Im betting he is running 11 in the 1/8th while you run 11s in the 1/4
