264whp stock 35th An 350Z Today I took a drive down to CP Racing to get a base Dyno for my stock 2005 35th an 350Z. I wanted to see what this "NEW" engine would be putting out before I started bolting on mods. Sharif was there with all the guys from Cp Racing, we were all guessing somewhere in the ball park of 225 thru 240 at best. The car ended up pulling 264.2whp on the best run. I had a set of Kinetix test pipes with me (resonated ones) so we thru those on and got a 270.1 whp on the best pull. The car kept pulling higher numbers each time we ran it untill it toped off with the numbers posted. Stay tune as in a week or so I will do another dyno with the HKS Ti dual exhaust, and possibility a APS kit to follow that(If Sharif can talk me into buying one of them). Big thanks to the guys at CP Racing and Sharif for taking time off thier current "BIG" project to mess with my car.

I will try to post the Dyno sheets tomorrow to include the Air fuel Dyno.

Kinetix test pipes (resonated) 6hp gain and good torque gains, dyno butt is happy, no rasp at all..

 

Wow, that's really high. What kind of a dyno was it?

 

Hmm, this is really high. Was this on a dynojet?? According to your numbers you should have 318 crank hp stock. Also, was there a smoothing effect on?

 

CP Racing has a Dyno Dynamics if I recall correctly. According to member Under Pressure, this dyno reads SIGNIFICANTLY lower then a dynojet :shrug: .. not sure if I buy that, especially now. I can definatly believe the numbers, but I would not believe if the car was on a Dynojet that it would be making another 25-30 HP like Under Pressure's thread on dyno comparison states.

BTW... get the APS kit... if you think your car is even remotely quick now, wait till you try it with some twins!

 

Correct CP Racing does have a Dyno Dynamics dyno, One of the guys there also told me that the dyno reads significantly lower, any how I will post all the dyno sheets today. I know the numbers are kind of high compare to what every one is getting even with minior mods.

 

thawk408 I notice you have the same engine, did you happen to get a base run on your car before any mods? Keep in mind we did over 6 runs on the dyno all together with the car stock it just kept making more power, so with that said many pepole when they go get thier car dyno pay for 3 runs on the dyno and then they get their Hi Five and slap on the a&s and sent home. If they know what thier doing they will run it untill it is running consistant numbers, and that is what the guys at CP Racing did.

 

I did get a baseline run. I ran on the dyno until we started loses power. I think we made 5 runs and the forth one was our best at 255rwhp stock. This was all on a dynojet and is SAE corrected with a smoothing factor of 3.

 

so basically you are making more than 320hp at the flyhweel stock?

you have a freak engine

 

They add 13% to the number so it is comparable to dynojets. Your numbers would have been 229.68 without the correction factor.

 

So the 264whp is with the 13%?

 

Why do you say that? According to underpressure Dyno Dynamics usually read the lowest out of all the dynos.

 

Here are the Dyno sheets
1.A/F
2.Kinetix test pipes resonated
3.Bone stock

 

i dynoed my 35th ann and pulled 248whp on a dynojet that whit test pipe,plenum spacer,y pipe,intake

 

This will quite alot of skeptics about the new motor. Esp m3 guys.

Unless you do have perfectly balanced Z motor.

You I agree with and believe you:

Attached is my Dyno sheet:

Back to Back Dyno - '03 6MT modded "G" vs. '05 Plenum moded only 6MT with "Z" Tube "G"

My car is a 2003 "G" 6MT Coupe.

Mods:
TechnoSquare Crawford Reflash ECU
JWT PopCharger with "Z" Tube
Crawford V4 Plenum
Crawford HiFlow Cats
Crawford Headers
Invidia G200 Dual Exhaust with "H" Pipe
Ground WiresBack to Back Dyno - '03 6MT modded "G" vs. '05 Plenum moded only 6MT with "Z" Tube "G"


I've attached the results My Lines are Blue, the 2005 with the Motordyne is Red. We peak about the same 248HP, but I peak 7-1/2 pound feet of torque higher then him. And if you look and the curves, I beat him in all the power ranges up to about 6000 RPM, we look the same from 6000 to 6500 where the new plenum runners, ECU and cam take me by about 1/2HP.

if that is 35th anniversary why the rev did not reach 7100rpm?

 

Why rev it to 7100rpm? Once peak hp has been reached its just going to fall. I dont think its going will spike once it falls.

 

yeah on a dyno it'll probably fall after peak power

in real world driving, you want to hold each gear as long as possible

 

Does anyone know exactly what has Nissan improved/adjusted for the 2005 300hp engine?

The powercurve shape (torque/pwr peaks etc) looks quite identical to the pre 2005, it drops power at the same rpm's even though it allows for more revs before the rev limiter cuts in etc

it's pretty minimal stuff

mainly it's ever so slightly different camshafts, the new lower plenum, stronger rods/rod bolts, and some barely noticable changes to the block - not really performance oriented changes on the block, just some tweaks I think. I think the pistons are also slightly different. Then it has the VTC

The VTC is really the only major reason to wanting the new engine. Otherwise you can still swap out rods, pistons, cams plenum etc

That's it otherwise. The ECU is mapped a little different I think
