Japan 3.5? Didn't know they exported to japan.
When you guys build cars to be exported do you do a big run of them in one day?

YB Normyl · Apr 30, 2003

Yes, usually with the 300M's, they try to keep them together. Mexican, Arabian and others (Treps or Concordes) the will mix with the others. A big run might be like, 20 to 30 in a day, not everyday though.

Hi ,so what's the best way to get rid of governor, swap ECU from R/T. I'm looking for some chip, but I can't find anythink what will help with gov..
BTW 98ES 3.2

That would be your best bet, unless you can get a dealer to flash your ECU to an R/T's etc. If you do a search in this board abot engine controllers and performance chips there should be a couple of options nut I don't know if the govenor is removed as well.

UHUHHUH? What be this uh "governer"?

Yeah i know it was, just speculating on how they govern the speed. I'm not that stupid

Hey guys, just a note on this issue.

On a recent trip to New Orleans, couldn't pass 118mph. Called a auto recycler here in Houston upon return and purchased a ECU for a 1995 Eagle Vision(3.5L) for $150 and swapped out. Now car will easily pass 130, but shifts at redline only, even at part throttle. When I put the orig. ECU back in it shifts fine. I will be taking this ECU out tomorrow and swapping it for a 1995 Intrepid ES model.

Did the Eagle Vision have Autostick in 1995? Could the ECU be causing the TCM to do this? Just wondering.

Rapping it out to Redline

Are You thinking you can sweep ECU between 3.5 and 3.2, I don't think so, but will love it.
BTW "YB Normyl" there is no chip , looks like nobody cares about speed limit, WHY!!!! It sucks!!!

Right, there is no changeable chip in the ECU, I was refering to companies that claim you can add a chip that overrides certain values. A bad example would be the ones on ebay, most of which are only resistors.

Some 95 Eagles came with autostick but that shouldn't make a difference because it's the TCM that's different. Was the comparison you made under the exact same circumstances?

Tiregod1 · May 3, 2003

YB,

The conditions were the same, Hot As Hell. Got the ECU for the Intrepid today and it works just fine so far, I will check the top end this weekend.

See Ya'll Later

The first gen 3.3 was drag limited to 115-it could max out 3rd gear for 115, and then hold that 115 in 4th
The first gen 3.5 could do 135, maxing out 3rd gear (the most efficient gear in the transmission), but could not hold that 135 in 3rd gear, they would drop down to 130.
Before Black94ES goes crazy, you said that the tach was 4200 rpms, that equates to 128 mph, you need to get the better dyno picture from the March 1997 MotorTrend it compares the 1st gen and 2nd gen engines.

The second gen 2.7 can do 130 flat out.
The short lived 3.2 could do 135 (or 140 in 3rd at 6650)
The 3.5's can do 140 [or 145 if you wanted (or could) rev to 6900 in 3rd]

Hey guys, I just returned from a short run to check out the new ECU.

I-10 heading west towards San Antonio from Katy is straight and flat, with a concrete divider. Perfect for testing top speed. I really only needed a short run to get it to over 135mph.

I have a good friend who is a state trooper here and he paced me up to 135, then he passed me!!:crazy: :crazy: :crazy:

BTW, he drives a 2002 Intrepid, unmarked of course. He didn't say just how fast he was going, but I would guess that he passed me at about a 10-15mph difference.

Driving that fast is not something I condone or do on a regular basis. I used to autocross,I've attended several driving schools and held a competition license for several years. I've never heard of any instructor condoning this type of behavior. But given the right conditions(time,traffic,weather,line of sight,road condition and the need for backup) it can be done with a certain modicum of safety. I still fit into my nomex, and I was wearing my helmet.

This little trip reinforced the need for those new struts(KYBs maybe?) and brakes(still looking for a kit for this car).

i have an intrepid 2000 2.7 and i went 115 on 3rd gear (very easy, plus i was with a friend, so thats an extra weight) and on 115 the car shifted to 4th gear. the rpm was between 6 and 6.5, i didnt notice the exact rpm because i was looking at the road! the red line of the rpm starts from 6.5 to 7 so i dont think i harmed the engine (i hope).

after that i didnt go faster because i had to exit.

but if the 3rd gear goes to 115 then the fourth should push till 130 at least!

hahaha, it was 4200rpms in 4th gear with torque converter disengaged

You're right about 3rd gear though, it shifted to fourth but didn't go much faster then o/d kicked in. So 130-140 is a good estimate.

I guess the speedo could be off.

You can checkout my dyno in the Performance 1st gen section, but it cuts at 5000rpms. (apparently 5000rpms is = 100mph in 3rd)

1998inferno · Jul 29, 2003

my 98 es 3.2 goes about 118 or so before the limiter kicks in... still in 3rd gear... dammit!!!!!!

Avenger · Jul 29, 2003

I'm too scared to try for 150, though I've hit 130 easily a couple of times.

alderran · Jul 29, 2003

Your car is not going to go 150... where are you getting that from?.. I have seen 139 posted in magazine articles

That 139 is drag limited. So, given the right atmospheric conditions and such, the car could potentially go 150mph.
