No, you need to reread that thread, and reread what he said. He said the torque was increased up top. That is, in the high rpm range, the torque was higher than it was on the stock track 350Z. And, if you look at the graph, you will see that it is indeed higher at 6000+ rpms. The max torque is certainly not higher, but at certain points, (above 6k rpm) the torque is higher than it was on the stock Z.

Sheesh.

Arguing on the internet is like running in the Special Olympics. Sure, you might win, but you know, even still, you are still qualified for the short bus. And yet I still do it.

As Chazm said ----substantial gains in torgue up top" Quote The max torque is certainly not higher. Quote Dave Sheesh
Dave Im not sure what thread we are talking about. He may be right like I said. I understand you like to make underlying remarks. Its fine with me. Just what do you know? I would like to thank you for all your smart remarks.
Like I care what you think on your little EYE-land. You know you must be lucky not to live with someone close to you that has someone in the the special olympics. Your the one that should be in the special olympics you jack ***. Get a surf board the waves are longer than your road.

 

Heh. It's so much fun to get someone all riled up.

 

I figured you would say something like that. surfs up

 

Really, where? I've been surfin' for 20+ years... and it's pretty flat here in FL right now...

 

I'm not going to be able to run the dyno because I've got to go out of town this weekend on business. I know that some of you were looking for the results quickly, so I am returning any funds that I receive. I will run the dyno, I just don't have a time frame at the moment. I don't feel right holding people's money for weeks at a time if I can't get the dyno scheduled. If you've sent funds via Paypal, I've refunded them to you. If you've sent me funds via mail, etc, I will return them to you once I receive them. I'm sorry guys, but my job comes before dyno results, ya know.

You can keep the money if you buy GEO & snM a few cold ones.
I think they both could use a few frosty's. Pasta

 

Gee Pasta, I was trying to say that max torque (which is around 5k rpms) doesn't go up at all, but if you look at the upper rpms (6k to 7200), torque is gained. It shows about a 8ft/lb torque gain in the upper rpms. Basically you can't just look at peak hp and torque gain, you have to look at the whole graph..........though I can't see anyone really feeling a difference in power with this gain.

I get really frustrated with dyno numbers. I will always go back to my old school way of thinking. The first thing that comes to mind is when you increase volume in your intake(Plenum) You loose low end power, You will always see a high end charge of HP.
The deal is you need a flat power and torque curve. In any racing environment torque is what wins races not HP. Your car like mine has a more built up high end charge to it. The trick here is to get it to run down low, Low end torque and drivability and get it to pull hard all the way to redline. Here is the problem I see right now. In your intake(plenum) you need high speed flow to pack the cylinders. The more air fuel mix the more power. Put any Plenum spacer, or pre 2005 plenums on you are going to loose that low end power that wins races. Or for the most part the joy of driving a car that has response. Here is the deal we all want. the best for are cars and sometimes we luck out and for the most part we do not.
This I can say I have found some very good results in my installs and the Pasta Mobile has some ***** down low now. I will wait for a Plenum change. Nissan may have done a great job with the new plenum. Im thinking of installing the pre 2005 lower plenum with the Crawford plenum. The pre 2005 plenums had longer runners. That makes more low end power. Papa Pasta

 

I have never seen anyone's G35 lose low end power, most gain low end power then gain again on the high end.

 

The Crawford plenum does infact make power on the 05 298-300hp motor however the overall gains are very minimal. Only in the last 800rpms of the powerband is the motor making more power than stock and that power is only 3 to 8whp. Yes, it's 3 to 8whp the VQ didn't have before however the car isn't going to be measurably faster in the 1/4 mile. How can this be? The reason is the gain is very minimal and spread out over a very small amount of rpm (800rpms). In a 1/4 mile race, the VQ spends very little time accelerating through this portion of the powerband.

1st gear 6300rpms to 7000rpms: maybe .3 seconds
2nd gear 6300rpms to 7000rpms: maybe .6 seconds
3rd gear 6300rpms to 7000rpms: maybe 1 second

Race over. In the 1/4 mile, it won't make any measureable difference in ET or MPH. The VQ might be fractionally (.1 seconds quicker at the top of 4th and 5th because the car spend more time accelerating through this rpm range, but not many of us have the money or ***** to drive at such speeds.

Power under the curve is key. If the plenum gained 8-10whp from 4900rpms to 7000rpms, then there probably would be a .1 second and 1mph gain with the plenum because the gain would be across the entire powerband, not just the last 40% of it.

 

Please forgive me for asking a question that has probably been asked 100 times.

Will this spacer give me the same results as it would if I completely replaced the plenum?

I'd much rather retain the stock look if possible and I'm not sure if I like the look of some of the aftermarket plenums out there.

Thanks,

Jeff

 

Yes it has. There are tons of threads and some even with dynos out there. Try a search =)

 

I have to say its nice to see someone with dyno numbers. People spend alot of money on mods and dont have any real facts or figures.

 

i just dynoed my 05 300hp engine whit test pipe,y pipe,and aam spacer
best pull 248whp whit a 226 max torque sae corrected and lowest 240whp
does number kind suck i was looking for 260whp+ so im like at 293 crank engine hp
can i say the 300hp oem engine is well overated that all bull**** marketing
a/f was very rich 11.5 in topend
the dyno brand is dynojet 248
