Absolutely.

 

The originator of this thread appears to be a troll. I suggest this thread be closed and this jerk be tossed. He has no meaningful contribution to this site. If you agree, inform a moderator and lets dump him.

 

Troll??? You decide.....

 

Jeeez,

The guy merely asked if there was any way to get more power out. After all the posts about turbos and S/C's, it looks like most here are interested in more power, so how come almost everyone treats this guy poorly? Cut him some slack and try to be a bit more respectful.

I would second what the two or three useful posters have stated. There will be ways to get more power, but right now is not a good time since the car a so new. Give the car some time, try to go to a driving school or track day to learn how to handle what is already there, and then in 6 months or a year come back and mod the hell out of the car.

-D'oh!

 

Listen, the guy is a Troll and he should be tossed out.
No soup for you either!

 

I personally can't think substantial power boosts without taking the FI route.

[sigh] I miss old skoo cars, and I miss the old emmission standards.

Look at all the fun my dad gets boosting his Z32 TT.... plans to get ECU, POP intake, and exhaust upgrades for over 60HP boost.

Me? POP intake... more sound, HP = -5
AHAHAHAHA! I don't mind the lost in power for cool engine sound.

 

I prototyped both the JWT pop charger and the B&B exhaust system for my 350Z. Stock hp was 227 at the rear wheels on the dyno, now 248. Simple math that equates to roughly 310 hp at the crank. Not much of an improvement, but I do get three things, one is a little improved gas mileage, second is the new stainless steel exhaust dropped 17 pounds in weight, and the third is the car now sounds like it is supposed to. Before the B&B exhaust, it sounded to ricey, now it is very throaty. If you want to hear what my Z sounds like go to www.bbexhaust.com. Also, Yuichi at strictlyz.com is selling the system for roughly $900.

 

"GM's 305hp rating is extremely conservative, they didn't want the LS1 f-body to steal any of the Vette's thunder, however it's commonly known that the F-body's LS1 makes pretty much the same 345hp as the Vette's. They generally put out the same hp to the rear wheels." LS1.com

One word: Underated
It is known that some LS1's have been known to put out those numbers stock at the wheels.
Winning an argument IS hard when you don't have your **** straight.
Never heard the mullet comment before either, why do some people have to resort to this

 

Hold the phone! You have a 350z with 310 ponies? I don't think anyone has been able to show dynos with actual hp gains. Will you be the first?

 

Let me get this straight, you have a JWT Pop Charger and a B&B exhaust, you gained 21hp at the rear wheels, but you have 310 at the crank instead of 308. Simple math is 310-287=23hp gain at the crank, not 21. Are you aware dyno runs from members on this site found the pop charger gave them a loss of 5hp, not a gain? The same thing has happened with a custom exhaust. No mod that has been tried here has yielded more power, usually less. What makes you so special, to gain 21 or 23hp, when others can't get squat increase? We are all ears.

 

In a meeting with Steve Ballmer, Senior Engineer with Nissan, In informed him that the stock dyno on the car was 227, or a 60hp drop from the stated crank hp of 287. He informed me that standard hp loss is between 18-20% from the crank to the rear wheels, in this case it was 20.9%. After modifications, the dyno result was 248. Therefore based on a 20% drop and a rear wheel hp of 248, that equates to a loss of 62 hp from the crank, i.e. my calculation of 310. I won't split hairs with you on the math, 308, 310. Whatever, I have realized a quantified increase. I am not the first either. I have read of several people that have realized performance increases.

Now, what I am really salivating over is to see if Stillen can fit that supercharger under the hood without a cutout. I believe that is going to be the only substantial hp increase out there.

I am really interested in seeing some numbers about this Stillen Supercharger aswell.

Does anyone have any idea when this will be released to the public and how far along they are?

I hate to break to you Ares, but GM actually underrated the Camaro Z28, SS and Firebird Formula, Trans Am, WS6, and Firehawk by a considerble amount.

I had my Trans Am dynoed at a local VW/Audi Tuner shop, and I pulled 312 HP and 330 TQ at the wheels SAE - the numbers are higher if you go by STD, but most people don't like to. The car was rated at 310 Flywheel.

ZunZet350Z dynoed 227 Wheel HP, and it is rated at 287 Flywheel. That is 21% drivetrain loss, which I think is a lot. If my car had 21% drivetrain loss (it should be equal or greater to the Z with heavier parts), then my flywheel HP would be 395. I think 85 Horsepower is a lot to gain from a lid (my only mod)...especially when you're lucky to get 10 out of it...

Get over it. Just because you don't want to believe it, doesn't mean its false and that all LS1 drivers are mullet wearing idiots.

 

ok ok, I didnt know, but one more question. this isnt a flame, this is an honest question.

your car has approx 90-100more HP than a Z, with mods or whatever, thats not the point. and way more torque, why did you only pull a 13.56? the Z seems to be capable of 13.9(Ive seen 13.8x but thats ok, well take a safe number)

why is there such a small difference when the comaro has almost a third more HP?

again this is not a flame, just seems like your car should be faster...

 

Run for president

 

ares, good question.
Answer: first of all, compare apples to apples. You say "the Z seems to be capable of 13.9" - what have you run? That point aside, I can barely get traction at the track. Seriously. If I drop the clutch from 2000 RPMS (hardly revving it), the tires just spin and spin...I have to bog the car out of the hole, or feather the clutch with some mad finesse to get a decent launch. This ruins E.T. - because you'll note that 60 ft times are critical to the overall ET at the dragstrip.

Put drag radials (like NITTO 555r2s) on the car, heat them up and actually launch well, and the car will drop about a half second. No joke. This is because the 60ft times dictate the 1/4 mile (and 1/8 mile even more) ET - anyone who has been to the dragstrip and raced will know this.

I'd love to see the person who puts down a 13.9 (or 13.8x as you've seen) at the dragstrip, *on street tires*, in a car with 227 RWHP that weighs over 3200 pounds without the driver.

My raceweight with myself and a 1/4 tank of gas is 3750 pounds. Next time you race at the track, go weigh your car. I don't do any weight reducing at all (like removing the spare, jack, rear seats, etc.).

My launch technique: feather the clutch *lightly* from 1800 rpms.
My shifting technique: no powershifting, regular style.

Remember that this is my daily driver...it gets driven to work everyday and taken on trips on the weekend. I don't want to ruin my clutch in 10,000 miles, nor do I want to break the rear end (notoriously weak in these cars). Sure, I could pick up a couple tenths with a crazy 5,000 RPM-feather-the-clutch-launch and another tenth or 2 by powershifting, but it isn't worth it to me when I don't have a backup car.

I am totally writing this as FYI - not flaming or anything. I like the 350Z, but I also dislike 'magazine' racing. Go to the track, see which cars run what times and with what mods. I haven't seen a 350Z at the track yet, but am looking forward to it.

I can tell you stories all day about what I've read on the boards, but it doesn't mean much until you see a guy (or gal) do a burnout in the box, roll into the lights, and rip of a 13 second pass. BTW, any stock LS1 can get into the 13s @ 100+ MPH without mods or street tires. Many have gotten into the 12s. I've personally seen a couple guys in Sacramento run 12.7s with drag radials with otherwise stock LS1s.

Finally, my car should be faster, but I drive it like a puss at the track compared to how I should to get the fastest time out of it. The reason? I can't afford to replace the parts that break. It's not the car, its the driver.

Ok, one last thing, really. I don't think my car has 395 horsepower. I also doubt the 350Z has 287 flywheel HP if it dynoes 227 at the wheels. I *know* my car has 312 honest HP - no matter what anyone says. I've been using 15% drivetrain loss as a general estimate for flywheel HP, but I personally think that is high for a manual (more like 12% IMHO if I could guess).

I'm more than happy to answer any more questions you have, or you can email me (amurray@nummi.com) if you want (I probably won't get any PMs) because I don't hang out here much.

 

How about a 13.88 @ 101mph... by a 2k2 Maxima 6-spd on stock tires (RE92 Potenzas = crap)!!!

His car is modded with intake, Y-pipe, RT CAT, and Greddy cat-back exhaust.

See this thread for complete information.

This was his run:
RT ... .552
60' .. 2.251
330 .. 5.974
1/8 .. 9.036
MPH .. 80.52
1000 . 11.660
1/4 .. 13.883
MPH .. 100.96

Granted, he did some weight reduction, he estimated 80-90 lbs (spare, seat), but the Maxima would still weigh close to 3200 lbs.

If a less powerful FWD car can do it, why not the 350Z?

You're right, the 60' time is critical to the 1/4 mile E/T.

 

ru4real, that is a good run. A few notes regarding apple to apples again:
1. This is a different car. Maxima vs. 350Z
2. intake, y-pipe, cats, exhaust - hardly stock.
3. Weight reduction. and the racewieght was not posted - only guessed.

There are too many variables there to have a discussion on the topic.

Who cares you ask? Well, the Trans Ams/Z28s that have intake, high flow cats, y-pipe, and catback, along with weight reduction, are running mid-low 12s at over 110 MPH. And it costs less than the Maxima.

 

Sorry, I posted in a hurry and didn't give more facts or explanation.
I posted because the Maxima's E/T should give hope to 350Z owners, who have the advantage of RWD and more hp, to obtain a 13.9 or better.
1. Yes, the Maxima is different than the 350Z. It has a less powerful version of the VQ35DE, it is FWD, and is classified as a "sporty" sedan. I'll reserve the term "sport sedan" for powerful sedans with RWD.
2. Yes, the mods are not insignificant, but they do not produce results on the Maxima like they do on some other cars, like F-bodies. I would estimate the mods gain 15-25 whp at the most. I looked on Maxima.org and it appears the owner has dyno'd his car to be 229hp, 230ft-lbs at the front wheels. I think that is less than what a 350Z makes at the rear wheels.
3. The Maxima driver listed his weight reduction as the spare wheel and tire and the rear seat. A stock wheel and tire is 50 lbs and the rear seat isn't more than that. I think his estimate is good, plus or minus 10lbs.

So, in the end, if a Maxima can achieve a 13.9, so should the 350Z. The Maxima and 350Z are impressive given that they only have 3.5L V6 engines (HP/Liter).

In no way was I trying to compare a Maxima to a Trans Am/Z28! Those cars are in a totally different class! I'm impressed by their performance, but I like the interior and amenities of my Maxima, thank you.
