Ahh yes forgot about the no rockers, higher shifts power dives.

Todd you'll have to show me all the tricks, I bet you got the wheel sensors down in 15 seconds a side now with the tire on. I'll try the ELC pump up too, first time for both,

good thing I'll have a resident gearhead hanging around, speaking of
oh ya 1200 post! L67 baby!!!!!!!

Poping the wheel sensors off is easy, turn to one direction, reach around, turn to other direction, reach around.

I can confirm the talk of launching the 2K with how it distributes weight with power. I had a 2.12 60' with my pulley and cam at Norwalk but it felt like a boat taking off waiting to plane off haha.

With the PCM now and extra timing, etc, it'* worse. 21 degrees of timing and no knock is making some good power.

I owned a 92 SSEi back in the day... that car was lighter and tighter than my 2K is, however, my 2K is a much more smooth vehicle that can become 'violent' when need be..

From my timeslips (I ran driverjohn'* 1992 SSEi twice, and each of the 2000'* once), the 60' times are this:

My 1993 SSEi:
2.239
2.344
2.298
2.360

driverjohn'* 1992 SSEi (K&N drop-in filter, Flowmaster Exhaust):
2.404
2.412

PontiacDad/PontiacMom'* 2000 SSEi (Bone-Evil, 3.3" pulley, gutted airbox w/ K&N, INTENSE PCM, TOG headers, good rubber, etc):
2.247

2000SilverBullet'* 2000 SSEi (similar mods to Bone-Evil, but 3.4" pulley and a straight-in cone intake, DHP PCM, TOG headers, and other significant exhaust work):
2.360

Keep in mind this is just from my own slips. All cars may have had better times. If all these, my 93 had the best 60', and was accomplished with simple bolt-on mods. I'm 1.1 seconds quicker in the 1/4 than a 92 with intake and exhaust, which I think is significant. Without the weight distribution problem on the 2000'*, this would be a different story, but remember that the 92 and 93 reach their tq and hp peaks quicker, which is also having an effect on this. Someone needs to invent a stiffener/brace/dampener or something for the rear of the 2000'* that can quickly pin in and out Beats the hell out of wheelie bars.

Id be intretested to see some 1/8 times mph and 1/4 mph as well,. Gives an indiciacation of where the car is making or not making power.

The TCS systems have me curious. When I had the 2000 GTP we would remove fuse #28 from the Junction Box under the hood. This completely disables the TCS as well as the Magnasteer.

Now that I have the 97 SSEi all I have done at the track is to turn off the TCS via the swith. That said, my best 60' time is 2.10 seconds. On the GTP, even with Potenza RE730 tires and TCS disabled, I never got as good a 60' time

Interesting...

Cheers,

Cheers,
The TCS switch on the 00'* do not disable tq mgmt, they disable the tire slip timing pull briefly but not entirely. My guess is (and I'm going to test this out at the track this weekend) that TQ MGMT is actually helping with your launch as its not allowing the tires to spin as much but your not getting full power at the launch.

To back this up ive noticed that my tires spin a lot more on the street before I hook my VSS back up after a day at the track. As soon as I put them back on, even after turning off TCS I notice the tires will no longer slip as much.

Next time at the track pull your VSS and see what kind of difference it makes on the launch (and trap speeds).

I'll try that this Sunday. Be curious to see, the TCS on the 97s is not as advanced as the 2000+, I can still lay good rubber even with TCS enabled, it just takes a couple of seconds for the system to react.

I assume the 2000+ Bonneville and the 1998 to 2003 GTP TCS are pretty similar, if not the same. I understand the Bonneville has Torque Management and only the 2004 GTP does.

A fellow nearby with a 2004 GTP has almost the same mods as TaylerD and Rogue and his best ET is 14.14. No doubt there is still a bit to be uncovered with TM, lightweight front ends and larger diameter wheels.

Cheers,

Yeah Foghorn I was gonna say, my 98 still can leave its mark with TC on. Why do you think Bonneville was late to get the updated TCS?
