It pisses me off everytime i race either a cobra or a trans am or something.... they pull on my G in 3rd gear abotu a car length... just a car length. although i am planning on doing these things whether they will put me up to par with these or not, i was just wondering, if i have ztube + p/c, plenum, cats, and exhaust done on my car (19inch volk gt-c's slow it down a little), will i be able to hang with cobra's and trans ams better? How many extra horses over stock will i be running, and what would be my qm times around (assuming that im a really good driver.... even tho im not haha). my car's setup is in my comment at the bottom, but i am adding my volks soon and then i will be in the market for exhaust, plenum, and cats shortly after.....

you're going to need a little more then that to hang with the big V8s. Especially if you run into any SVT cobras or LT1 Trans ams.....

Saw a fairly stock SVT run a 13.17 last night!

I think you are going to need F/I to hang with a cobra

spit a lil nitrous under the hood, then we'll c who's faster.

 

hmmm well the cobras ive raced have all been the older body style (98ish i thnk?) and they werent that much faster than me... until 3rd gear that is... i beat one guy through 1st and 2nd (he may have been driving an auto) but once i got into 3rd he pulled a length or two. Trans Am's arent low 13 cars are they? I mean... one SLOWLY walked on me... but it was really slowly and beat me by a hood length from 50-95 and i had to start at low rpm's in 3rd because of the gearing in the g.... I know that these cars will pull on me at those speeds because of displacement.. but 13.2 GODDAMN! lol

The cobras were not supercharged from the factory until 03 I believe, so anything older a NA G might hang with...

Pre-98 4th gen f-bodys (T/As and Z28s) were high 13 sec cars with traction and good drivers. Post 98's are low 13 even high 12 sec cars from the factory. New '03 and '04 Cobras turn 12s easily with good drivers. Add to this point that all of these cars accept mods VERY easily and cheaply. My mildly modded 96 auto Z28 turned low 13's with <$1000 in mods. Heads/cam package on an LS1 (98+ f-bodys) can put an additional 75-100rwhp and get them into the very high 300's/low 400's rwhp and DEEP into the 12s in the 1/4.

It isn't horsepower that's beating you- it's torque. And one thing good 'ol American Muscle cars do is produce loads of it. My modified '68 Roadrunner produces 520hp and 640ft.lbs.torque and runs in the mid-11's. As the old saying goes, "there's no replacement for displacement." You really can't compare a G35 to a Cobra or Trans Am- two entirely different beasts. My RR will smoke even a FI modded G or 350Z in the quarter, but I sure as hell wouldn't want to race either one on a twisting, turning country road!

 

Hmmmm, not try to say too much, but i have a mildly modded 03 cobra, under 2000.00 in parts. Put it this way, 900 bucks got me 473 hp and 492 lbs of torque, just a pulley, tunner, and an x-pipe. I may be picking up a G35 tomorrow, of course it feels like a slug, but that can always be fixed. There is absolutely no way a g35 unless "heavily modded" would beat an 03 or 04 cobra, especially with a cobra with a few mods. I have had a few cars in the past 2 years so im looking forward to this, i had an 02 s2000 with a custom turbo, STI, 03 cobra and now hopefully a g35... Also many sportbikes.

I have both an 04 G35 and an 03 Cobra and there is no way the G is going to come close! First of all it is hard to find a Cobra that is stock as everyone buys them to mod immediately. These cars respond well to mods. A simple 2.8 supercharger pulley, chip and exhaust will put you in the 450rwhp to 480 rwtq range. Stock the Cobra's average around 360rwhp and 360rwtq and is easily high 12 sec car off the lot. By the way there are no automatic Cobra's as stated earlier. The G35 and the Cobra are two cars with a different purpose. If you bought the G35 for speed, then I think you purchased the wrong car. If you had trouble racing a pre-99 Cobra in 3rd gear, then don't even try an 03 or later, they will hurt your feelings bad.

Yeah I think I hurt the 03 SVT Cobras feelings last night when my little Japan rice burner beat his time buy a whopping 0.01 seconds 13.150 vs 13.160. All it had was an intake on it and he claimed it was putting down 365hp.

Of course I have $11,000 in mods compared to his $279

LOL!! Good thing he didn't have $11,000 in mods!
On a BIG plus side- there is simply no car on the road today (leaving out autos in the $100,000+market) that is more graceful or beautiful than the G. Infiniti did damn good, hands down. Style, performance, and those really nice LONG stares you get while driving the G- not bad for a car under $40 grand.

 

Very impressive times for the g35. Hopefully I will be able to do the same with mine....
365 sounds reasonable with just an intake, and I am talking 365 SAE corrected to the wheels. 03-04 cobras dyno stock about 355-360, I wouldnt doubt if the fella had an intake, he may have been able to dyno slightly higher than that. With an intake, and off road x-pipe, I ran a 12.14@115. with the other mods, plus a mishift, I ran 12.04 obviously spinning tires in 1st and 2nd with a mis shift going into 3rd. However it was consistently in the 121-122 mph, meaning in a roll, the car was pretty quick, not the fastest but quick enough to run with most daily driver street cars. It's going to be an interesting year for my G35 if I manage to keep it long enough.....

01' GSXR1000 - retired
02' S2000 Turbo - retired
04' STI - retired
03' Cobra - maybe reitred 7-10
04 ZX10r - maybe retired 7-10
04' G35 coupe - Maybe 7-10

 

Good Job Kevin, way to humble him. I am surprised you found one with only an intake. I am sure you convinced him to change that pulley sooner.

How well to G35's respond to forced induction because that is what is going to be necessary for a G35 to hold it's own against a Trans am or Cobra? The G35's high compression engine must only allow 6-7 psi, right? I am new to these cars and would like to know more.

The Cobra's internals are forged and it's blower comes stock with 8psi, changing to 2.93 pulley adds 4 psi more and 2.8 adds 4.8 more. The only problem with this mod is more heat is generated causing a loss in efficiency as blower is being overspun 25-30% more than designed.

The G doesn't actually respond too well due in fact to the high compression. I am running 8lbs, and some people will step up to the 10lb pully, but, like the cobra I have heard that due to added heat you really are not increasing power that much. Also, there is talk that the piston sleeves in the block won't hold more then then 10lbs reliably. After that the tranny and rear end will need work to hold much more then 400 rwhp.

Combine all that with extremely high parts costs and higher then normal install prices and this is a VERY expensive car to make fast.
