dynod my 33gtst auto

[Bo0sT_JuNkY]

i dynoed my 33 gtst today and got 207.2 hp @150kph and 837nm @130kph ,@9 psi

Mods are fmic ,safc,pod filter

Also found out that the exhuast is stuffed cause when dynod at 11psi it produced 203hp so i need to get a 3inch and i should be able to get 220hp at 12psi.

Anyone else got a read out with the same mods???Is this a good read out???

[rev210]

done in 3rd gear?

[GTS-t VSPEC]

rev, it's and auto.

The power sounds about right. Finish off the exhaust and then run 12psi, should be up near the 230rwhp mark.

837nm of torque ???

if this is right, can someone explain to me how this can be?

[GTS-t VSPEC]

That's not correct. It is most likely tractive effort that is recorded, and while you can determine the actaul torque made it is not the same. 870Nm would be a 500+rwhp car.

yeah... more to the effort than the actual amount!

Did you wind the boost to 9psi ?

cause one you do the zorst... you should have 9psi without dialing in anymore.

Just cause it's more flowing and the turb's won't be spinning as hard due to less restrictive exhaust.

Running more boost on a restrictive exhaust will have the negative effect you noted.

make sure it's turbo back though. the most important part in my opinion is the dump pipe. Allows the turb's to spin way more freely.

where in melbourne did u dyno it?

thats preety low considering u got fmic and s-afc

[Bo0sT_JuNkY]

I dynoed it at ATS ,Yeah i sounded pretty low to but its a auto and theres more off a loss through the drivetrain then a manual.Does anybody no the exact amount of power u lose through the drive train??Also i just spoke to ats and they said they can make a 3inch exhaust mandrel bent from turbo back tig welded with hi flow cat +muffler for $1100.And it should go heaps better ,i looked at the cat and u cant even see through it !!also the middle muffler has broken up .Most skyline's run rich yet mine was leaning out due to poor airflow .If i can put done 250hp when im finished with more boost and a good tune ill be happy,if not then ill have to just put a microtech and T04.lol

[Bo0sT_JuNkY]

dyno

[Guest INASNT]

fark 14:1 a/f ratios it way to high. did they even tune the s-afc properly

[Bo0sT_JuNkY]

Well he reckons a 14.7 is a perfect a/f ratio for a skyline but sometimes they like it a bit leaner or richer,What should the a/f ratio be?????????

[Guest INASNT]

hmm 14.7 in a turbo car?? wtf is that guy thinking who told u that.

12.1 -12.5 is the leanest u would wanna go unless u want to start melting pistons and alike.

justy remember we only have 98 ron fuel in aus where as in japan they run on 100+ octane

[MRK25T]

I got my car dyno'd this week and it reached a max of 175.1hp.

The line on the graph stoped at 5500rpm, I cant remember what run this was, but the car was hitting boost cut all the time.

I'll try and attach a scanned image of it when I go to gf place later so someone can explain if my car is running ok or not.

14.7:1 is perfect burn, for cruising that is not full throttle.

[Guest INASNT]

but when u do a dyno run its at full throttle so...

[rs73]

When my car was auto, stock exhaust, stock airbox, stock boost, I dyno-ed once and got 138rwkw / 185hp.

I haven't dynoed it again now that it's manual, 3" turbo back trust mx exhaust, boost bleed valve @ 9psi.

[Bo0sT_JuNkY]

spoke to him again and he explained that the calabration on the a/f sensor was out cause i have a 6inch dump pipe and two much of the exhaust gas gets around it???And that the standard settings where even leaner ??i dont no but he did tune it for cruising more than power ,And they have been working on turbo cars for like 20years .Ill see how it is after the exhaust is on and post the dyno sheet up.Also about the torque i think its traction too cause i thought 837nm is alot of torque for any low mod car.

might be time to find another workshop... there must be oodles of

them in Melb that guys from on here have used with more success.

Look for one that wont pull your pee pee.

[Frosty]

not really

rally cars have 300rwhp and do 600+nm torque

so it doesnt really matter its the way the car is done and modified

[GTS-t VSPEC]

Frosty,

Rally cars are designed for high torque, most street cars aren't.
