Not Enough Power

[GTSR22]

hi guys

we just got the car back from a very good tuner and it isnt making enough power for the goodies on it.

we also took the car to another very good tuner and he had the same problem

the car is making 252 rwkw.

here are the mods

R33N1 ENGINE (6000 K'S OLD)

R34 N1 TURBOS

GREDDY CAM WHEELS

TRUST 4INCH EXAUGHST FROM TURBO BACK

HKS DRAG INTERCOOLER 105MM

APEXI POWER FC

800 CC SARD INJECTORS

AFTERMARKET TURBO INTAKE PIPES

Z32 AIR FLOW METERS

APEXI AIR PODS.

AFTER MARKET INTERCOOLER PIPING

CATCH CAN

should we be making more power? or am i over stating?

does anyone have any suggestions as both tuners have checked everything and cant find anything wrong with it

thanks guys

cheers

You should be seeing that much power.. perhaps a little more with sufficient boost levels. Your next step is to upgrade the turbos.

oh and if you havent already, take it to RacePace - best GTR tuner in Victoria.

[SABBAi]

Upgrade the turbo's from R34 N1's? Snowman is running N1 and is making more power than that.

Just as another note, one of the Vic board members cars, an R33 GTR is making 260rwkw, with a standard engine, cam gears, hard pipes, 1bar boost, 4" exhaust and pods with standard AFMs.

I would expect more power than that. What boost level are you running? How did they set up the cam timing? What does the ignition plot look like? Standard boost controller?

Shouldn't you making 350kw+ ?

[ferni]

snowman has HKS 2530's not N1 turbos.

But yes i'd expect closer to 300rwkw+ there and a good tuner would be able to tell you why you're not hitting that mark.

[Paradizzle]

Maybe you forgot to bolt one of the turbo's on?

[Beer Baron]

i would think that combo should be good for 300-350rwkw. i'm making 1 kw more than you with only:

32 engine

stock 32 turbos

hard pipe kit

cam gears

pods

cat back exhaust (front half still standard)

1 bar boost

power FC

[Downforce]

yeah chris, i believe andrew has 2530's.. either way N1's aren't that special.

[GTSR22]

we are running 15 psi and it has been to both ben and nizpro

[Snowman]

we are running 15 psi and it has been to both ben and nizpro

<{POST_SNAPBACK}>

15psi is why you are making 252rwkw's.

To get upto 300kw+ you'll need to increase the boost to 19-20psi.

My car on stock turbo's at 15psi was making 255rwkw's. The N1's are basically the same just a steel wheel which should be able to hold more boost. If you have stated 15psi as a max then the power you have got is what you should expect.

If you want more power wind up the boost.

Cheers.

[GTSR22]

ok thanks snowy

will ask them to change that

[West]

Depend on the condition of your engine too by the way. What does Ben say about that? I'm sure Ben can extract more out of it.

Mine is a 94R32 with 14psi making 250kw@rear, with Ben's tune ofcourse.

You're sure your is @AW not rear?

[R31Nismoid]

Wasnt the reason the car was not tuned with more than 15psi the first time because it was expiriencing detonation??????

And that was more than likely due to the choice of fuel that was used i thought?

Bit hard to say its not making the power that it should if you aint putting decent go-go juice into the tank and screwing boost into it.

Its making spot on power for what your running it at essentially.

[JAGR33]

TURN UP THE BOOOOOOOOOOOOOOOOOOOST!!!!!!!!

[Ronin 09]

isn't ben's dyno 'low' (not that numbers mean anything, dynos are tuning tools, rah rah rah, it's the relative increase etc etc etc rant rant rant)

[GTSR22]

yes bens tune with 95 octane was 212rwkw on nizpro's dyno. were on his it was 232 rwkw.

and it is only rwkw bevause we had to drop the front tail shaft

[JAGR33]

95 octane????

<{POST_SNAPBACK}>

95Octane? That sounds shocking. You sure man, if it is then no doubt you're making that power!

[thommo]

i would have thought that unless you are living in a remote area there is no reason not to run 98 octane fuel in a modified car.

will give plenty more headroom for your tuner to run more boost without the detonation you've been seeing using the crappy 95 ron.

[GTSR22]

no, it is running 98 octane now,

before when it was first tuned it was only running a mixture of 98 and 95 octane.

everyone has said the turbos? is this correct?
