How come Turbo G's aren't as fast as they should be?

Thanks. Here is a picture.
And this was the engine bay taken by my cel phone...lol.
The GP could not do a single thing better than my G so no regrets here...except be easier to mod. Hopefully when I start getting my new pay checks ( I just got a promotion..weee ) I can fix the only thing I don't fully enjoy about my G.

Fast drag runs aren't all about power, there's also traction, weight, gearing, and the shape of the power curve that contribute. As others have said, G's don't get good traction due to wheel hop, they're heavy and who knows that the power curve looks like on these 600HP cars. The transmission is geared for maximum acceleration at about 300HP, and when you add more power, I bet that 1st and 2nd gears will be too short to get good times since you'll probably be shifting sooner than cars built for drag racing.
The G isn't a drag racer. It's a high performance, luxury cruiser. Other cars will kick its *** on the drag strip and on the track very easily.

11's is a sad time.......? Anyways I believe most G owners build their cars to be fast but still be able to drive in the streets. Anytime faster than 10sec is not even drivable in the streets. In my opinion, if people want a REALLY fast car, they would not fix up G's in the first place, they would fix up something like a honda civic which is much cheaper and can get them under 11 second much quicker with less cost.
Also anything faster than 10 second I would consider funny cars, and G's are more of a sport/luxurious car hence their heavy weight like BMWs and Lexus..

11's is hella fast don't get me wrong...but 11's is a sad time imo for the potential I see in these cars.
Most of the 10 second GP's are daily drivers ( some even rack up over 20K miles a year ). Just put some slicks on and race gas and bam...you're in the 10's. I've seen a lot of STI's and EVO's that can do the same.
Another funny thing is that there is a 350Z down here in Puerto Rico that ran a 9.7@144mph. While 350Z are lighter than G's...it's not by a huge amount ( about 300lbs ). I see no reason G's shouldnt be able to be in the high 9's or at least knocking on 9's door.

Have you never seen a Z06, Terminator, or Supra?? Granted, it takes engine work, but go youtube or streetfire these cars and you will see them hit 10's and that they are completely streetable. Not to mention all the exotics out there.......

I don't know if that many G's are running drag slicks or if those who are are properly geared to run w/ their hp levels. Additionally you were running an auto which lets you build boost off the line. Look at their trap speeds and you'll see the cars likely have plenty power but a hell of a time off the light. The 4spd auto of the GTP might actually be a benefit since it must have had tall gears to allow the car to have any kind of highway fuel mileage. Coupled w/ the stock torque from a 3.8L meant for a supercharger and you've got a pretty potent combination. G's for the most part only have 3.5L and a fairly narrow N/A torque band. Depending on the turbo setup, trying to launch a 3500lb+ car(prob closer to 3650 w/ turbo) that can't build boost till its moving off the line on ~260lb-ft of torque isn't going to be great. A more apt comparison would be someone w/ a built auto or a turbo400 when you're talking about a straight drag setup.
What were your 60ft times when you ran your fastest time? My brother had a '97 Maxima that I built the turbo setup for and got a 13.7@106mph out of when he was dynoing 306whp/317tq. It was auto and we were running on 215/19's(show wheels) at the time. The car had a 2.5 sec 60' and was a good bit slower to 60' than even a stock 5spd. Car weighed 3300lb w/ driver at the time. If every G is clearing 60' ~2 second range, then it's all about the launch.
Most of the Supra's I've seen have one hell of a time launching on the 6spd to get into the 9's and lower. Throw a turbo400 in and 8's are possible w/ ~900+whp and drag radials. Probably need another 200-300whp +one hell of a driver to do the same w/ a stick.

As a matter of fact...I know of a red Evo 9 that runs 9's full interior on street tires and it's the guys daily driver ( he actually goes to work in it ). 1/2 of all Evos/STi's down here run 10's or less...lol. It's not even fun anymore.

I agree with everything you said...I wonder why the auto isn't more popular with high power G's. It seems to be ultra sturdy with minimal mods and with a high stall converter it should allow a G to launch with sick 60' times. My GP did 1.9 60ft times on 400TW street tires but I have to admit that GP's tend to launch pretty good for a FWD car.
I figure that a VQ35 with smallish turbos ( maybe dual GT2860R's on .64 T25 housings? ) that max out at 600whp ( quick spool and big power IS possible ) with a highish stall converter should do great times.
Who's first?
The fact is that the G is not built for drag. Not only the G, but most Japanese cars, except for those fully built *** cars. Let's try the G on a track and see how it works. Anyways, Z is much better than G. But i still love the G because of the looks.

GP's, EVO's nor STI's are built for drag...especially the GP which isn't built for anything but to be a grocery getter. Heck, they even have Pontiac Bonnevilles in the 10's and Hyundai accents in the 8's. Non of these cars are built for drag racing...but at least the G35 comes with a pretty awesome drivetrain.
I wonder if the lack of caring is the reason why they aren't so fast?
Well, the G is more like a luxury car than a sport car. If you wanna go for a drag, get some Muscles. Muscle cars are more likely built for drag. But i'll stick to *** cars anyways (because im Asian 
); especially the G and the Z, no matter theyr not fast or else.

True...but buying a muscle car for drag racing is no fun at all...it's almost not fair even. lol.
I may be ignorant but from what I have been able to see, the fastest G is only in the 11's. IMO that's pretty sad for the amazing drivetrain these cars have ( at least that's how I see it ).
I come from a 2000 Pontiac Grand Prix and the car ran 12.6@111mph with 357whp. This was full interior, everything nearly stock except for the fact that I removed the supercharger and turbocharged it ( what I mean is that the entire drivetrain was stock except for what is needed to turbocharge it and add the proper fueling. ). Heck, it was even on the stock exhaust.
Now keep in mind that this car weighs 3400+lbs and is FWD with a 4 speed auto tranny and a 3.8L V6 with 2 valves per cylinder that produce 200hp when N/A and 240hp when supercharged ( yes, it makes less hp that a VQ even though it's got more displacement and a supercharger to boot ).
In the GP forums you have mildly modded GP's doing 11's to heavily modded GP's doing 8's ( The quickest being 8.6@159mph ).
So my question is...why are't their any G's in the 8's, or 9's, or even 10's for that matter? I see people with 600+whp so the power is there...but where are the times?

Plus, the gearing isn't great plus no real LSD, along with stiff suspension (even stock) and these are your results.

The biggest problem with any FI system is weight coupled with the stock weight. Expect with any setup you will be adding 100 lbs or greater to the car.

I think the reason I gave before of people just not caring enough is the best one so far...gives me something to shoot for.
