^^ traction looks nice i wouldn't know anything about it

TonyGXP

I pulled 1.76 60's on the stock tires.. all about weight transfer and the RIGHT set of wheels driving the power home

had a FWD GP GXP went 13.6 stock.. with a 2.01 60', could barely leave at 1/3 throttle in that car..

How much did you pay for the TBSS? ^^

TVS_SS

I drove one around for a while.. Tons of fun! but lots of gas $$

I couldnt imagine funding that fuel bill, especially with my lead foot.

i did not know gxp's were that fast stock what was the trap speed?

TonyGXP

$30.5k it's an LT II, loaded exc for Nav/DVD


102+, they are all trapping around same (100-102+) what hurts them is the final drive ratio (2.93) you go through the traps at the top of 2nd gear.

SS4ME

I'm having a hard time believing this. How in the hell do I dust GXP's in my Cobalt which runs a measely 14.4? I've beaten GXP's at the track or on the street, stock and slightly modified! Unless you are talking about the GXP with the displacement on demand V8, then I totally believe you. If your speaking the last generation with the SC/V6, I have to call BS! Do they call the new Grand Prix with the V8 a GXP?

ParkedCarChaser

Yep.

The SC/V6s were GTPs

SS4ME

Didn't they make a GXP also? I thought they had a ram-air hood and that was what made them different then the GTP. I could be wrong?

3fo893013L

2004-05 GP GTP = 3800 V6 Series Supercharged
2006+ GP GXP = 5.3L V8

GXP = SS/SC in 1/4 mile stock for stock.

ParkedCarChaser

Apparently not. He said he ran a 13.6 stock... so that means GXP>>>SS/SC in 1/4 mile stock for stock.

3fo893013L

Maybe with Drags. It's only a 14.3 1/4 mile car w/good driver.

Another independent study has this

Engine : V8, DOHC, front engine FWD
Displacement : 4,565 cc
Valve : 32 valves, 4 valves per cylinder
Transmission : 4-spd automatic
Fuel economy : city - 17 mpg
highway - 24 mpg

Suspension : F - Independent MacPherson strut
R - Independent MacPherson strut
Brakes : F - Vented discs
R - Solid discs

Horsepower : 275 hp @ 5600 rpm
Torque : 300 lb-ft @ 4000 rpm
Redline : 6500 rpm

Top speed : 138 mph
0-60 mph : 6.6 sec.
0-ź mile : 14.8 sec @ 95.0 mph
60-0 braking distance : 126 ft
200 ft skidpad : 0.81 g

Curb Weight : 3790 lbs
Overall length : 202.6 in.
Wheelbase : 112.2 in.
Overall Width : 74.2 in.
Height : 56.6 in.

It's also a heavy car. but I've seen them at my track run low 14's. Something fishy with a 13.6 time. That car had to have a hella 60'fter.

ParkedCarChaser

Ummm... I don't know what car those stats are from, but the new GXPs have 303hp.

What kind of 60' does it take to get the new mustangs in the mid-13s???? Exactly.

Tomtwtwtw

Those are numbers from a Bonneville GXP. The Grand Prix is lighter, and of course, has the 303 hp pushrod engine, not the Northstar.

ParkedCarChaser

PWNT!

TonyGXP

C&D and MT mags don't or I should say "didn't" take the time to perfect the 1/4 times as I have, and most other GP GXP driver's.. spinning the tires out to the 60' will net you a mid 14 and you haveto hold 2nd gear until 100mph, the computer makes it shift at WOT at about 88mph, waaay short of redline.. First time out I let it shift auto and went 14.3 @98, form then on out I used the TapShift and never ran a 14 again, ran a dozen or more 13.7-13.8's with a best of 13.6 @102.. IMO the order of the SS's is like this stock for stock, average driver.... from what I've seen at the track I am sure there are differing opinions, just how I've seen it play out so far..

1)2WD TBSS
2)AWD TBSS
3)ImpalaSS (LS4 5.3)
4)SC/SS

2-4 can be interchangable depending on driver, especially 3 & 4..

here's the slip from the 13.6 run..







here's a couple 1st time outs with my BONESTOCK at the time TBSS...





the TBSS has NEVER made a 14 second pass... which still amazes me till this day..

articzap

Why would it make a 14 second pass? Is it that hard to put your foot to floor and hold it there till its done?

TonyGXP

when you're 2wd AND HAVE 400ft tq and the trans short shifts at WOT? yeah actually it is. I've picked up .2+ by altering my launch and shift points. when you learn to get your car to run 1.6 60's on street tires, come talk to me..
go do some resaarch and see how many guys couldn't break into the 13's stock with their SS's... it's just pretty funny how every Magazine list the truck as a 14.2-14.3 @98 or so and my first ever run was a 13.55 @102 and an AWD went 13.9 @100.. goes to show you NOT to believe what they write about, go out and run your own car, guessing does nothing, or going by other's times... you need your own to know what the deal is..

agreed TBSS is no joke 102 traps stock is sick in a heavy truck

TonyGXP

new stock Vettes are running between 112-115 stock, that weight and aero drag is HUGE... even with 4.10 gears look at the drop in MPH... I wasn't satisfied with my truck until I can firmly take on a new C6 at the track (w/o losing any DD characteristics)

SStud

I think you're thinking GTX. SLP's version of the Grand prix of the 97-2003 generation.
