Dyno Tune

[Pulp]

Thought I'd start a new thread, maybe make it a sticky, on dyno figures of peoples rides, wouldn't mind seeing some stock dyno readings as well as some readings after your modifications

Post away!

That's interesting!!!

Here is my before and after. my mechanic's dyno read really low number compare to others

have done exhaust, y pipe, metal cats, 350z intake tube and plenum spacer, only gained 7.3hp, really disappointed

[Pulp]

Hey is that manual 6sp or auto? seems a little low actually, I was under the impression the V35s came stock with about 206-210kw (not at the wheels), so roughly ~158rwkw or ~211rwhp??

It's auto and actually it's too low. been serached all the stock dyno's on g35driver.com they have average 230-240hp

Its not a V35, but its close enough.

2003 VQ35DE in a Z33

JWT Popcharger

5/16" Intake Manifold Spacer

Motordyne MREV2

Reflashed factory ECU with higher redline

Unichip Piggyback

TopSpeed Extractors

Crawford Catalytic Converters

HiTech Exhaust

I've got several exhaust leaks at the moment, and the car's feeling a bit off, so I'm probably making less right now.

my car has been dynoed on the Unigroup Dyno earlier this year at a dyno day

made 178rwkw STOCK which is about right with the claimed 206kw engine power output

will post the graph up once i get a hold of it

its a 6mt 2004 v35

I've got my 2004 v35 dynoed at 153 kw at the rear wheels???

The only performance mod done is a cat back exhaust. Its no where near the 170 kw margin.

The dyno guy did have some trouble fixing the sensor into the single exhaust though. Should there be 2 sensors fixed if you've got a dual exhaust system??

[BLISTC]

there is more drive train loss if you have an auto

keep that in mind

[BenzLe]

That's funny...Mine happens to be the 6MT

[BLISTC]

as promised...

my stock 6mt '04 V35......

Lets bring back this thread.

I dyno 177rwkw right now but picking up the V with new extractors tomorrow then i'll dyno again. (the extractors are really hard to put on)

When i got my car i put it on the dyno and got 163rwkw stock 03 auto.

Do you guys think there is about a 10kw diff in manuel and auto?

[BLISTC]

v35 paul,

i have since gone back to unigroup and redynoed my car.

i have serious doubts that their dyno was calibrated properly when the previous owner had done the 177kw run when it was stock.

I have since had the car dynoed twice since then.

First time, was after i installed the plenum spacer and CF Z-Tube car made 164rwkw. ISMR dyno.

The 2nd time, i installed the stillen Air intake, lightweight flywheel / clutch and teh Motordyne exhaust. Car made 174kw. Unigroup dyno.

I seriously doubt the mods i have done to this car have made it slower. I suspect the dyno may have been reading "happy" and have since been calibrated. the 174rwkw seems about right. The car does feel faster now than before, there is no doubt about it. So it definatley hasnt lost power.

[Touge Kyousou]

Near when i first bought (exhaust, panel filter, tube, ground kit) - 131rwkw @ ISMR

Located and fixed overheating issue

Middle of ownership (exhaust, panel flter, tube, ground kit, HKS plugs, nismo thermostat, spacer) - 170rwkw @ ISMR

Just recently (ECU reflashed and rev limiter raised) - 182rwkw @ SAS

Car felt progressively/proportionately faster as i fixed the heat issue and added more mods. It's decent speed now, i'm very happy with it. I don't find myself thinking how i could make it faster anymore really.

Now it's more braking power i need.

Oh sorry, 03 6mt vq35de.

Edit - 182rwkw run also had gramlights on rear, a bit lighter than the factory 18"s. Even though they are wider and have larger tires on.

What did you reflash with?

[Touge Kyousou]

Custom flash (for my engine and mods) at SAS.

A few people with Z/V have got it done at SAS.. but they are in Sydney unfortunately (if you were looking to chase that).

Car is giving 5.9s to 100 with a soft/medium launch, can't complain for n/a luxo cruiser

[BLISTC]

how much did they charge u for the reflash ?

wont the stock ecu re-learn over what has been flashed?

[Touge Kyousou]

$1200.

It doesn't relearn, because they actually overwrite/write in their own data. I know one chip on the ECU actually gets replaced so unsure if AFR targets and ignition mapping is overwritten or even written onto the new chip they put in.

Proof that it doesn't relearn is the car hasn't pinged once since the flash/tune. Factory mapping had my engine pinging sometimes (quite a common problem on Z/V on forums).

If you do go ahead, just remember it's an n/a engine, don't expect massive amounts of difference before and after.

I did it more to get rid of the pinging myself. They managed to give me some noticeable mid range and top end gains however my low end suffered as ignition had to be pulled back considerably as the factory mapping was too aggressive causing the low end pinging.

[BLISTC]

i might get it done when i throw some cams and headers and test pipes in the mix.

i dont know if it is all worth it, staying na, or going FI with a supercharger kit.

i want a reliable car end of the day though so i might give FI a miss.
