My 95 5.2 would hit the gov around 105 or 110. After I got the Mopar performance computer there was no gov. I got it up to around 115-120 and I had enough lol. It had headers, exhaust, all the bolt on's.
I really truly want to know what his modifications are and why he seems to think that his 15 year old brick will defy the laws of physics. My friend has a full Dinan M3 that has a confirmed top speed of 163... And it took quite a while to get there. Sorry, but a ZJ just won't do that unless it's purpose built for drag racing, blown, completely stripped, etc.
You are more than welcome to come for a visit . If it doesn't do 150 , I will pay for your flight . I have been there and not exaggerating , I never do !
Was I surprised , yes , but , it is a fact . And no , I'm not going to do it again and take a pic of my speedo which hits 140 and I buried it . Trying my jeep at that speed was crazy enough , but to take a pics or carry a passenger to do so is worse again .
My computer has a custom tune too. To make it a LOT more stable at triple digit speeds I put HD ADDCO Front and Rear Sway Bars on it. I was up to 130 and saw traffic a ways up ahead on a usually clear section of pretty straight interstate and had to back off. It was very stable and I would not hesitate trying for 140 to see if it still wanted more like it did at 130.
On the way home from the dealership after picking up my new T/A I buried the speedo way past the 100 MPH marking, got a 160 speedo in it now. Ive always liked going fast. Did some amatuer racing years ago and some course work at Watkins Glen and learned a real lot from it, especially in the rain at speed was helpful learning how to recover from pushing it a little to hard. This guy I knew who always owned fast Camaros but had never been in a T/A with a beefier suspension. Had him crapping his pants on an entrance ramp to the interstate when we hit 95 at the top of the ramp. Wasnt a real tight curve, but a long slow curve with perfect slope that made the car want to stick like glue. I asked him if he wanted to try again for an even 100 MPH and he turned white. Everyone that owns a T/A has their favorite ramps, that is one of my favorites because you enter the bottom at 55 MPH in third and just put it to the floor. It wants fourth gear right around 100 MPH so your complete focus is the car and the road. Car is a 79 and still has all the factory paint except for the rear spoiler ends and the Wheel Flares. They have been repainted three or four times because they really work and the paint gets sand blasted off them every few years from the dust in the air that flows over them at higher speeds.
How stable is yours at 150 and what suspension mods have you done to keep it stable??
I was about to say "Hey there's a discussion about this going on a tsf.net right now!" Then I realized newfie was the one that started it over there. It's tricky when you use different screen names...

It was on a straight run . Don't think I'd want to be on a turn lol.
It was just fine for stability , was also on a new strip of black top i drive daily . Jen , at that time I had new lower ca's from IRO , new sway bar bushings and end link front and rear , and new monroe reflex shocks . You know what these things can do if you hit 130 . You still had about 1000 rpm left and it showed no sign of letting up at that point .
Nick , walmart has some reading glasses you should look into and yeah , I'm crazy for even trying it but hey , I can admit that lol
I've had my stock 5.2 up to 115, I don't doubt the niner will do 140+, but I need better tires before I try it. I will try it though.
ANd the 5.2 handles fine at 100, when I was getting use to the niner I kept hitting 100 by accident because I was lead footing like it was the 5.2, no stability problems and that was with the PO's ****e shocks.
