Something wrong?

DISCLAIMER:
It's only considered constructive criticism when the person criticizing actually knows what they're talking about.
END OF DISCLAIMER.


Why the hell would you recommend a 2.25" full catback exhaust to gain power?? Are you aware that the stock midpipe size for the 03-06 sedan is 2.5"? You should go out and measure one before you talk out of your ***.

Again, your issue with Megan is your own personal opinion. You've never had any experience with the SPECIFIC product I'm using, so for you to compare coilovers for your GTI over an exhaust for the G35 is like comparing apples and oranges from the same company. That's the same as saying, "I don't like Del Monte produce, because I had one bad apple from them, so everything they make sucks!"

At least you're right about one thing, though, or almost right. My wheels/tires setup are great! The combined weight is at least 5lbs lighter than stock. When I get a chance I'll put both my stock 17"s and 19" wheels on a commercialized scale, take pics, and show them to you. I'd like to hear what you have to say about them next...

The art of driving a 5AT in sports mode does sound kinda funny. I bet you're thinking, "It's an automatic! WTF are you talking about?" Hahaha, sure, let's see some vids of you drive a pretty much stock 5AT at the track. I wanna see what kind of numbers you get.

Don't worry about the gearing, because I'm not done with that yet. Let me share a secret with you. There's actually quite a few people with N/A G35's and 350z's that actually go shorter than the 3.55 final drive you're referring to. The 2007 G35 sedans all have a 3.7 FD, and there's an aftermarket Central 20 3.9 FD, and lastly a 4.083 FD option from a Nissan Frontier. Now, I don't know about you (well you don't have one, so yeah), but people who've had them installed swears by the 3.9 or 4.083 gears. To quote the people who have them, "It's like the best thing I ever bought for my car! It feels the same as having force induction."

Here's the link to the search button if you want to find out more about shorter gears:

Lastly, what's a G35 sedan minus a stillen z-tube, skunk2 plenum spacer, and 3" axleback? Well, just a bone stock car, of course! The thought of having a tune over 3 minor mods haven't actually crossed my mind yet. Maybe a few months down the road, when I have exhaust cut outs and even shorter gears (OH NOOO!!). Nonetheless, that's a good advice to give someone with a pretty much stock car

Well, sir, I would like to thank you for your awesome feedback about my car. I hope you had as much as fun as I did. Next time, don't think about it too hard. You don't have to wait a week to think of what to say next, just say what's on your mind.

Sincerely yours,
Stillmatic

2.25 supposedly has better exhaust scavenging. I don't know enough about aftermarket systems to say whether 2.5 or 2.25 is better, but many knowledgeable forums members have recommended that size to me, and Borla uses it for their systems. Also, 2.5 OD or ID. Either way, a stock crush bent 2.5" system is not going to flow as well as a mandrel bent 2.25 system that includes a y-pipe with the diameter.

I base my opinion off of my experience, the experiences of others on this board, and the opinions and experiences of my friend whose shop is partially sponsored by Megan.

Based on that, Megan is crap.

5lbs for all four wheels/tires or per individual wheel. Also, are the wheels 5 lbs lighter or is the combo 5lbs lighter. I wasn't sure if by "combination" you mean combined weight of the wheels/tires or of the all four wheels or wheels/tires. If they prove to be lighter, congratulations! You made one right choice in terms of modding your car.

You're right it's oh so difficult to drive an automatic at the track. Personally, I put it in manumatic and in "2" from the start and let the transmission shift on its own for the 1-2 shift, then I shift it into 3rd myself at around 62mph or 6700ish rpms. Then I ride out third until the end of the run running pretty close to my redline. I also tq brake the launch anywhere from 1500-2500 depending on track prep.

I haven't gone to the track since I was stock, but when I was stock I ran a 14.68@96.12. I haven't been back since my mods, but I assume that it will run at least a little faster since I have added a cat-back, spacer, z-tube w.filter (does nothing), grounding wires, and I stripped trunk.

Hey, thanks for letting me in on the secrets of after market FD ratios and the search button function. Maybe you could've used the search button before buying a 3inch mid-pipe or a 3inch axle back which you currently run. That would make sense.

I was actually going to suggest that you should look into the 3.7 FD offered by Nismo, but then again what do I know. I was hoping you could answer my question about rpm in 4th gear you were in when you crossed the line? That would help me make my recommendation, but you seem to have it all figured out.

I was actually hoping that you would get a tune after you get a real exhaust and maybe some test pipes/HFC's. That would be logical. With what you have, the only reason to get a tune/reflash would be the higher redline which would make sense with your less than ideal final drive ratio.


I wish I could mod my car like yours, but unfortunately in order to get to your trap speed I would need to lose some hp. Then again, you are well on your way to getting even slower if you're going to install exhaust cut-outs, but please, do prove me wrong.


I feel like I can learn so much from your extensive knowledge about the G35 and possible modifications.

Thanks for your help

^^

Arguing with you is like arguing with a 5th grader. Please post again when you've successfully ran a 1/4 pass faster than 14.47 seconds. Seems like you and I have pretty much the same mods, well, I've done less to my car. Please provide us with videos, time slips and dyno graphs of all your claims, as that's what I've done in the 1st post of this thread (less the dyno part).

For the record, I never asked anyone how to make my car faster, so I didn't really need your so called "constructive criticism" in the first place. Nor, have I claimed to be a know it all G35 expert, I was simply replying to your expertise...

I wish I could answer your question about the RPM, but I don't remember what it was when I reached the finish line.

To recap,
My 19" wheels/tires shaved off at least 5lbs (in each corner) of rotational mass
-- Your suggestion: My wheels are heavy and make me slower

I have a STOCK 05-06 2.5" crushed bent midpipe, and 3" Megan Racing axleback
-- Your suggestion: Get 2.25" full catback because they flow better, and Megan Racing is crap because you compared my Megan axleback to your Megan coilovers for your GTI. Claimed that people gained power with 2.25" exhaust, and you lost power with an axleback with no dynographs to prove it.

You believe that exhaust cut outs will make me slower.
You have no idea what you're talking about, or know where I plan to do the cutouts. Have you ever dyno'd or ran a car with open header??

I say that there's an art to driving a 5AT in sports mode.
-- Your response: Driving an automatic is a no brainer, and recommend I should get a grounding kit because it cut your shifting time in half according to your butt dyno. Yet, you mentioned that you when you launch, you let the computer do the shifting from 1st to 2nd gear... If it's not that hard, why let the computer do the shifting??

My 3.5 FD is not ideal
If so, why would you think about suggesting an even shorter 3.7 FD? You're just contradicting yourself. I understand that it's hurting my trap speed, but at the same time it's helping my 60' time. Go do the math...

That's all I have to say.

God bless smart people!

You're just being a straight idiot now.

I am glad that you enjoy taking initial statements from an earlier post.

Honestly, I didn't feel like I would have to explain these things, but hey, why not.

In terms of the 1/4mile, I am currently away from my car for the next week, and the only local track here (I'm out of my home state) is an 1/8th mile. Be sure that I will take it there as soon as I can. I will be back in my home state in early August where I will also take my car to the 1/4mi strip. My guess is that I will be pretty close to 14.47, but I don't bench race, so we'll have to see.

In the end, it's not about me, it's about you.

Regardless, I will dig up my slip of the 14.6. That's no problem. I'm pretty sure I still have it.

Wheels:
I didn't know anything about your wheels, so I used common sense and figured that your larger wheel setup weighs more. If you look at my next post, you would've seen that I acknowledged that your wheels are lighter and that's a good thing.

Exhaust:
Why would Borla sell a system that's 2.25, and I also think that Stillen's system is either 2.25 or 2.38. There are also plenty of 350z owners using 2.5" systems complaining about low end torque loss. I expect to dyno with my Borla TD soon, so then I will be able to tell you the difference.

I have in fact ran my car with open headers for about a day. I broke two exhaust bolts removing the stock system, and I had to drive to the auto parts w/an open header (30 miles round trip).

I didn't dyno it, but it felt SLOW AS ****. It's not a scientific analysis, but it felt considerably slower than how it was before. 0-60 was crap, the whole thing felt like garbage, but please, run open headers on your car and experience it for yourself.

Again, you keep using info that I said from an earlier post. In terms of the Grounding Kit, the car shifts about 250-300rpms sooner than before. Instead of trying to shift up at 6000 in order to shift by 6600, I can now go to about 6200 or 6300 before I need to click the shifter. I can show you the user feedback thread for Gordgee's Grounding Kit. Many people have shared the same experience.

I let the computer do the shifting because it shifts faster on it's own than when you do it in MM. There is less "lag" when it shifts into second. Also, you don't have to worry about possibly hitting the rev limiter on the upshift.

Another way to try is leaving it in "D" from the start, and letting the car shift on its own from 1st to 2nd, and then you push it into MM and continue on your own. Supposedly "D" has better line pressure and thus faster shifts with less lag. I haven't tried this method, but I will at some point.

FD:
I suggested the 3.7 because I think that it will get you closer to peak hp by the end of the run. Right now, you seem to shift into a less than ideal spot on the track and you probably finish before you make peak hp.

With the 3.7 you might get to peak hp faster than before and this gain back some trap speed. You could also be better off with something like a 3.9 or a 4.x, but I certainly don't know.





I enjoy your selective attention. You seem to pick quotes from an earlier reply in hopes of making me look "dumb".

Outside of the wheels, which I didn't even know what they were, what I am saying is correct. I will try to get you my 14.6 slip, and I was going to go to the track anyway, but thanks for the extra motivation.

This is why the internet makes you stupid.

Just the fact that you are both posting to a G35 forum means you already have more in common then not. It sounds like you both have very strong opinions but I bet if you met in real life, no one would be calling the other person an idiot. In real life it would be easier to trade stories and insights while still respecting each others viewpoints.

But this is the internet, so disregard what I just wrote and continue flaming each other until one person calls the other a **** or you both get bored and declare yourself the winner.

hahahahahah, i'm so glad i found this thread... BTW to the two dueling poster's, my sedan is better than both of urs!!! hahahahahha, love it!!!

Your sedan is hot!

thanks, ur temper is hot... LOL. yeah, like the other guy said, if you two met in real life you'ld be boys. i've been in a few battles on the forums and after i read this it brought it all back, hahahahah. ya know what made me squash it? the picture thread w/everyone's faces on it, i saw the dude i was all pi$$ed at and i was like, "dayum, this dude look's like he could be my homie!" so, yeah... peace in the streets, hahahahha

I guess it is the internet, so whatever, but I have my opinions.

Maybe hero can enlighten me with his 1/8th mi and trap so that I have something to shoot for when I go to the strip
