The only thing I have as far as a GTech goes is an iPhone app that uses the phones accelerometer. Probably not the most accurate. Maybe this spring I'll go to the drag strip and see what she'll do. The only problem is the local track is 1/8 mile.

As far as "tight", one of the Northstar'ss attributes is it'* taking forever to get tight, worn in. And the reason some many resort to the "Italian tuneup" LOL. Ya an 1/8 mile I imagine is going to show somewhat slow to it'* 1/4 time. The engine would just start breathing. As the GXP gets a little older I am sure we will see more times posted. It'* easy for someone with a say 90'* Bonneville to quip in the forum, "well why haven't you taken the car to the track" back in the flame war days....."Maybe because I just paid pennies under $40,000 for it???" I think was on most owners mind.

i doubt i'll ever track mine, its not even worth the embarrassment.
6:15:00 PM Track update:
"Oh look at that V8 on the 1/4 mile! it just took off like a bat!!!"
9:16:15 PM Track update:
"WOW! that was a new 1/4 mile world record!!!! "


but you guys had it lucky back in 04 & 05 for the GXP being high 30s
here in Canada they were going for high high 40s if not few pennies over 50k

its fine, theres lots of slow cars at the track. i took my 88 olds cutlass coupe with a 2.8 down one night cause there was something wrong with my bird and there was actually a woman with a 4dr early 90'* cs and we ended up racing a few times. at the places ive gone theres usually trucks and ricers, the gxp would be faster than all those normal cars.

whats an Italian tuneup?

i'd take the MC...

with all 160HP/180TQ and 3300 lbs of heft plus me, it should pull a high 16 assuming i don't kill the tires.

it'* about fun, not ETs.

essentially, beating on the car just a little bit...

generally, WOT throughout all of second gear should do it, preferably where it is legal and somewhat acceptable to do so(freeway on-ramp is a good one, especially if it'* uphill).

depending on your shift points, that should net you somewhere between 70-90MPH at the end of second.

thats actually kind of funny because there is a guy who drives like that at work takes on ramps at speeds where the 4 tires are howlin, and hes very Italian. its funny to me cause he thinks hes a displaced racecar driver and hes had a intrepid and now hes got a vibe.

"The Italian Tuneup"
When it was first mentioned years ago (after it became apparent it worked) was to take the car our on the highway and drop it back into second, put the throttle to the floor until nearing the rev limiter (or recommended RPM max) NorthStars have a reputation (more so in older days) of the rings having taking an extended time of seating, and the combustion chamber carbon fouling when driven around like a granny. To me that'* a bit hard on a car/transmission. The alternative (my choice) is just find places to start from a standstill and WOT through the gears a couple times. And feel it "breath" a little better afterwards.

ive only owned my 05' gxp for about a month and a half, but i have to tell you i think its a sexy, sleek, fast full-sized car. and after putting on a pair of flow masters the BEST sounding car ive heard in awhile.
