and yes, i know there is a dyno forum its quiet in there, so i figured i would post here. If a mod feels this is wrong, please move the thread..thanks!

I went on a dyno dynamics dyno. Doing some research, it seems they read low anywhere between 10-12% from a dynojet. I posted a thread here, if you want to comment on a dynojet vs dyno dynamics

they dyno operator said that on a dynojet i should be at 255whp, which doesnt make sense as 10% would put me at 266??? idk, and i dont really care, the car sounds great and the motor seems healthy to me!

 

These numbers seem right for your mods, sounds good too!

 

all you have for engine mods are h/cb/wai? and you put down 242? are you tuned

 

You rev to 7400?

 

no tuning, and yes, just I/H/E the exhaust is 2.5"

 

wow thats nuts if you put a y, spacers and a block plate you would be putting down 270 at the wheels on that dyno.

yeeeaaaa!! u made more than my auto i am also confused to the 7400 rpm... care to explain

 

my headers have a y pipe




i did, but i wonder what you would make on this dyno, and what i would make on a dynojet. i dont know why the pulls goto 7400, he hit the rev limit in every pull..

 

fo real fo real, on a dynojet, a car with I/H/E makes roughly around those numbers... any other mods than what u listed???

 

nope, well my rims and tires are 7-8 lbs than stock..lol

 

suuuuuuuuuuuuuuuuuure lol

 

That's some nice validation there, Hotshot. Good for you.

 

WOW! That is one great wheel if it saves you like 30 lbs over stockies!!

 

The lighter wheels def make a difference. Thanks for sharing; you've got one stout motor.

 

Low mileage.

 

A low milage motor can also be abused and neglected; by stout I meant a well taken care of motor and/or drivetrain.

 

iirc stock 50lbs, the 18s i had were 55lbs and the 17s i have now are 43lbs

i believe so as well, when i went back to 17s the car accelerated better

and babied from day one. thanks for the comments guys

 

Great info; I need to weigh my Ti Wheels and my new 18s; i'm sure lighter wheels will help drastically.

 

Very true. I should have said, "well-maintained and low mileage."

Hotshot, you should lay off driving for a few months and let me catch up to you.

 

well, i need to change my sig, im at 63K now!

 

wow, I thought i babied mine...

Mine is at 71K.

 

How much does your car weigh if you don't mine me asking?

 

The light weight wheels definitely help.

I can't tell from your chart, is that standard numbers or SAE corrected? Remember the SAE corrected numbers allow for a more accururate comparison between cars. Although with DD dyno it's kind of tough anyway.

Grand hustle, did you get SAE numbers on your runs?

 

I'm also at 63k miles....

I need to swap out the Rotella 5w-40 Syn, in another 1600 miles; and time to switch over the Mobil 1.

 

have no idea, although im sure its one of the heavier maximas, it is a fully loaded car. the wheels are the only saving grace next time i goto the track i will have the car weighed, thats not till spring though..

 

Nice numbers, I have the same color max as yours, just hit 76k. Personally I think the GLE rims from a 5.5 gen look better/newer, I currently have the stock SE 17s, is there a big difference in weight? The SE's should be lighter right?

 

Error 404 : torque not found

what mods are you looking to do next

 

yeah, it looks like the torque numbers are under or about 220, which is really strange. maybe the DD reads especially low on torque

 

I'm still under 54K miles at the moment. I guess you'd have to lay off for a whole year for me to catch up to you.

Hoping my low mileage engine is "stout" too!

So... tell us again why ran the numbers on your car? Curiosity? Confidence? ECU Flash?

 

20k miles on my engine

Nissan replaced the old engine with a brand spankin new 0-mile engine in May 2007 due the old one burning oil. Going to dyno soon

 

tein coilovers since my garbage jics cant handle track days

dyno dynamics are said to read low, but my hp seems ok. either way, im happy with my #'s

 

hot damn hotshot! very nice!!!

im pumped about my new car now cant wait to mod more and also cant wait to make a dyno run in a couple weeks to see what my stock numbers are.

B

 

No biggie, just wondering...

 

idk... but iirc i didnt, im sure with the smoothing set to 5, im sure the sae corrected numbers would be between 230-232whp... non the less, great with the mods i got... i wanna get mines tuned before i get anything corrected

 

well, my friend has a shop, and was doing a dyno day, so i said why not. my car always felt strong, and YEARS ago i went on a dynojet with just an intake and did 218whp/228tq so i wanted to see how much more power i got from my headers and c/b

did you ever dyno your car before? arent you officially stock again though? i thought i read a thread some where that you were demodding but keeping the car..

 

I wanted to sell it, and I tried my hardest, but it wouldnt sell. Turning it back to stock proved harder than I imagined. Couldnt track down suspenion parts, headers etc. So I just kept it, probably will keep it for good as my DD.

First dyno run I did with my HS headers was when the new engine was put in. Never got to dyno with my old engine. I have to go back on dyno with my CM headers, exhaust and all the other little bolt ons. I dont have a AFC though...still hoping for some good #s though

 

do you remember your #'s?

 

congrats for u hotshot..........

 

Sometimes to get a generic tach signal they will hold the rpm's at a certain point for a few seconds to let the dyno computer calculate the rpm based off how fast the rollers are turning compared to the tach in the car. Lets say he wanted to hold the rpm's steady at 3,000 rpm for this but accidently held it a little off at say 2,900 rpms. You would then be throwing the dyno calculations off (rpm only).
