This guy boasts about 60.6WHP gains with NA modifications......is this possible for our G's as well....ur thoughts are more than welcome. Below is the link:

that sounds about right. with just intake/headers/cats/plenum/exhaust + tuning, you gain about 40whp. with cams - about 20 more.

 

Slightly skeptical but I guess it's possible. The problem is that he never did his own baseline and doesn't seem to know a whole bunch about tuning himself. The tuner *could have* changed a few parameters on the dyno just to make it spit out higher numbers to make the guy happy. I hope this wouldn't happen but it is possible.

I'd wait until the cams are defined and a few others follow this set up before I went and dropped that kind of money on NA mods.

 

although i have to agree that w/o valid baseline dyno and one after all his mods were done that i am skeptical on the gains....this other guy 'alberto' on that same forum ran a 13.13 @ 107 with all bolt ons, NO headers NO cams....

thats pretty damn impressive...

I call BS on the 13.13. It must have been done at one of the "fast" tracks like Alamo.

 

ya sounds 2 good 2 be true, but his sig includes a video, timeslip and a bunch of other 'evidence' of his run. he's in MD so im gonna guess he ran at MIR (maryland inter. raceway)?? i dont think anyone the Z board doubts him...

 

He dynoed on a Dastek (brake) dyno, which will typically show higher numbers than a Dynojet. It doesn't means it's any better or worse than other dynos, it just spits out different numbers. Numbers are all relative to the dyno model and make.

I don't think there's anything to call BS about. The truth is the Z crowd, as a whole, is a lot more drag/road race experienced than G crowd. Alberto Z's is far from stock. His mods are JWT Pop-charger, Crawford Plenum, Test-pipes, Crank Pulley, Injen Exhaust, Technosquare ECU, and most importantly....SLICKS. A 5000rpm launch in a 3100lb car with 260whp can result in a 13.1@107mph. His 60 foots are low 1.9s and high 1.8s. That's why his ET is so good. I've been preaching this for nearly a year, a G35 6MT is more than capable of 13.4-13.6 with slicks and minimal bolt-ons. The problem is most G owners couldn't fathom the idea of buying a $400 set of slicks and wheels for drag racing. Any car capable of 98mph in the 1/4 mile, is more than capable of 13.8s with a 1.9 60 foot. Alberto also runs at Atco and his best passes were in the cool spring air. Atco is a pretty fast track and he admits it. Regardless, you run what you run. This is the same track where a stock 350Z auto pulled a 13.6@101mph with a 1.9 60 foot (street tires).

 

This is SOOOO true. When I had my Mustang, it was purely a drag crowd and the things they did to improve 1/4mi times wouldn't necessarily be considered street friendly. Hell, some of them pulled the engine belt off completely so that no accessories would be running and thus gave them the most hp to the wheels possible. Other tricks like icing down the intake, running shorter slicks, taking out seats and other accessories greatly improved 1/4mi times.

So just because our cars don't normally run 13s doesn't mean that it can't. We're just not willing to go to the extremes that others are doing to get that ET.

 

Have you had a chance to dyno your car or run the quarter mile after all of these mods?

 

Yep, I've been reamed pretty hard when I said a lightly modified 6MT could probably hit a 13.3. When I mention things like removing passenger seats (-60lbs), spare tire (-25lbs), floor mats (-10lbs), skinny light rims and tires in the front (-40lbs), slicks on light rims in the back (-40lbs), lightweight battery (-28lbs) and 4-5 gallons of 100 octane (good for 6-8whp on these cars, -110lbs), you've shed nearly 320lbs in curb weight and freed up 80lbs in rotational weight. That's really significant. Then factor in about 20whp/wtq in simple bolt-ons and you've taken a 6MT sedan from a power to weight ratio (not including drive) of ~14.5:1 to a ~12.5:1.

Slicks will make all the difference in the world.

If a 205whp/195wtq 2,700lb 95-97 Maxima 5MTs on slicks can do 13.4-13.5@102mph, there's no doubt in my mind that a 250whp/245wtq 3,100 G35 6MT sedan could do a 13.3-13.4. It's just a matter of if someone is willing to go to the lengths to do it. Don't say it can't be done.

No one will remember that the car was set up for the track, what they'll remember is that a NA G35 sedan went 13.3s@104mph.

 

I couldnt agree with you more. I think the mentality is 'what difference will this make, or that make'. but the truth is it all adds up....

 

no, i haven't, but will do some time in the near future. pretty curious.
