so i drove the bird to work today, and this guy with a gxp saw it and started askin everyone who's it was....finally he found out it was me and immediately said we NEED to race...now just from talkin to the guy, he has no knowledge about his own car except that its fast....my only mods are poly mounts, Lt's and ory....no tune, no lid, ....even with a bad driver, does he still stand a chance of winning?
I believe the g8 gxp is listed at 13.2, with that in mind I believe with ur mods u should take him but its gonna be close depending on both partys driving skills and traction.
I agreeQuote:

I assume a g8 gxp we are talking about? There is like 4 gxp models
Yes it is a g8 gxp....either 2009 or 2010..im not sure
Spend the extra hundred for a lid b4 the track it makes a difference. My car ran 13.2 with terrible traction and no longtubes so you should have him if he's stock. And if u lose,I'm sure that will only make u wanna mod ur car.....defeat leaves a very bitter taste in your mouth.
you're gonna want a tune......
wont be able to get a tune before friday....but at least ill have some kind of baseline even though i already have headers...if he beats me, then it wont be long lived....i can promise that...the ol lady wont stand for it...
Does she have a sister?
Bad driver statement means you're a M6? It might come down to your shifting if so...
He will probably get you out of the gate.
Yes, if g8 gxp it Was only out for 2009.
My friend ran 12.9x stock, but has been practicing. This guys sounds like a bonehead. Do you know if he has an a6 or m6? Driver error may screw him if a m6, either way the have some traction issues from a dig unless he's practiced.
He has the advantage.
headers with no tune is gonna hurt you....I don't think the question is "does he have a chance" as much as it is "do you have a chance?"
actually, 5 that I know of off the top of my head.Quote:

I corrected it as soon as I typed it as I erred. Cell phone was slow. You beat me. Thx buddy :)Quote:

I thought all the G8 GXPs were manuals? I might be wrong about the transmissions,but being that the T/A is probably lighter than the G8 that might also help
The G8 GXP was available with a manual. Not all are so equipped.
right......I believe it was available in the GXP but wasn't available in the GT if my memory serves me correctly.Quote:

I'm kinda curious to know how this turns out now. Let us know how you do (good or bad)..
Ok, now that I've read up on this GXP creature, you'd better have your sh** together. Good luck.
gxp has the edge
well, dude has been out of the office for a bit, so im still waiting on him....but as soon as it happens, ill post the video for sure.
Jive ass! I'm waiting.
me too!!!Quote:

no way! im ready win or lose...i wont feel bad if i lose...hes got a better car...but the main hold up is that he is an engineer that works at our headquarters, and i work at our research lab...he only pops in if hes got a project happenin. im waiting....
I think you have him!!! Keep the tank near empty and get rid of everything in the car that you don't need (CD's included/spare tire/jack/washer fluid/etc..) Drop some pounds in the rear tires (Not too much) and waste his ass!!!!
:woo::woo::woo:
Also fill ur car up with Helium balloons! Put a net to hold them back so one won't get in your line of sight.
Definitely make sure your ashtray is empty too!!! :lmao:
you guys got jokes, eh? in all seriousness, i think i can take him at the track, or at least run neck and neck..
Hopefully and if you lose well....suck that helium and Tell him to fuck off.
I was serious :true:
Why have shit sitting in your car that you don't need while you race :dunno:
I always take out everything and stay low on gas ;)
i usually keep around a quarter tank and remove the spare when goin to the track...
I run about an 1/8th tank. A gallon of gas weighs about 6.1lbs!Quote:

Unless my math is wrong.....or if you get the gas in the early morning it could be more dense! lol
Or someones way of additional weight to hook
From my understanding Gas weighs less then water. Your math is right but liquid weight and dry weight are measured differentlyQuote:

Gas station is about 5 miles from the track. Little do people know (I found out by accident) but our gas gauges will go about a centimeter below E before its truely empty. Try not to run it that low because its hard on the fuel pump but it has happened so I don't sweat it :shrug:Quote:

Actually liquid weight and dry weight are measured the same way. The math is right but it's based on volume so the ounce to pound conversion won't work. You are correct gas weighs around 6.1 lbs per gallon.Quote:

:thumbup: Exactly. I learned that stuff early on pure stock racing on little F70-14 bias plys. More weight in the trunk....Quote:

I would never run my car low on fuel. Especially when going wot. Guess I'm just weird.
40 psi is fairly high for street tires IMHO :dunno:Quote:

I know I cut my one of my best 60' with 28lbs in my street tires :dunno:
I know the launch is key but a full tank is a lot of weight to get moving once you get off the line. I'll try anything once though :lol:
:yup: I didn't say I would ever do that...Someone else in this thread did :)Quote:

Start with a full tank and go from there. That's about 95 lbs. give or take.Quote:

Light in the center means it needs more air pressure. When it's even,,,it's a good starting point for the track when you get there. I found 40 psi to work exceptionally well on the 275/40-17's. Even the old bias plys I use like alot of air as well. From there it's all weight bias and sneaky suspension tricks. We weren't allowed any obvious weight bias, so we would put water in the spare tire. Sometimes even a larger spare tire than what the car was actually running to hold more water, or run the spare with a 7" rim instead of the 6" rims on the car, again more room for water. That's about as far as I ever went with weight bias in the stock class. Got me a best of 1.87 60 foot times on F70-14 bias plys :rotfl:
But when running a 4th gen on test and tune, no rules apply. I'd have all kinds of crap in the trunk for weight bias, my laptop for tuning, the cooler packed with drinks, even had a bag of stuff from the store after shopping earlier that day. :) I've never had the spare out of the car either. Mainly also because I'd drive the cars to the track, and I didn't want my junk laying in the pits, probably wouldn't be there when I got back.
Sticky tires are a completely different ballgame however.
Good infoQuote:

I have added weight with amp's and a sub in the back. The Hoosier's here do not like much air in them, 15 to 20 pounds. You can run so low that a bead lock will be needed. I drive to the track with the slicks on. While they are not street legal I have never had an issue. They also come out on the street from time to time. You just have to watch the weather. But if you do get caught in rain just park it.Quote:

That will be a close run but it really does depend on the driver.:burnout:
Yeah, I was that way once.....:brick:Quote:

He's another suggestion.... run C16 race fuel!! Should bump up your hp quite a bit. he wouldn't know, doesn't even have to be C16 i'd just do a quick search and see whatever octane is around 101 or 103. u'd be good.
ALso, some people claim the G8 GXPs run 13.2s stock. That is with a pro driver on a good day im sure. You also have an auto so get a good launch, i'd say at around 2,000rpm only and power to weight difference you should have him no problem!
And whats taking so long tell this guy to quit hidin in the bushes and come out and play. Lock it up or store it where it belongs.....
he came in last week but didnt really say anything to me...he got in his car and i happened to be outside in the parkin lot...i expected him to get on it hard but he just eased on out like normal.
Really? Because everything I've ever read says that your car has to be tuned to run that high of grade to even see the effects and without a tune, it actually doesn't do anything.Quote:

The difference in how fast the fuel burns could suggest u need to dump slightly more fuel, maybe not. Hope someone who tested it out on a LS series car could chime in.
pretty sure they do.
I think 13.2 is pretty common. local htown guy was doing 12.98 stock with m6, but he had some practice.Quote:

I like to take white shoe polish and write 13.2 on the back window then partially wipe it off. Some figure they can roll over me and take the bait. Some give a look like "yea right!". Either way your doin what you like.
