Wanted to fine tune my ride a bit further before MAS coming up soon, throwing it on the dyno there for a bit of fun. Further from my mods already I put a s/s Hiflow 3" cat in and it made a huge difference. Was thinking about going with some octain booster and a few other little tricks......but decided against it, thought id just be proud of whatever i could get off pump fuel (synergy8000).

The tuning went far beyond what I had hope for!!!! initially after the last tune i had 224kW @ the rears.....so i was thinking, hopefully low 230's?? but low an behold.......my beast pumped out 248kW @ the rears!!!! i was STOKED to say the least :(

probably also worth mentioning that this set up is still a little on the rich side at top end (which I prefer to be safe) and still on STANDARD INJECTORS :headspin:

anyway, only few people really understood my excitement, so i thought I'd come on here an share my good news!! Fingers crossed that the dyno @ MAS reads a little higher than most (which I'm told they usually do) an I can get a hold of a 250kW+ dyno sheet :wassup:

theres a pic attatched of the dyno sheet. RED line= power BLUE=torque

the lower lines are from a few tunes ago, i think stock turbo @ full boost before i replaced it (round 18psi)

nice number.

but sorry to say that from that graph that doesn't look driveable at all.

at 100mk/h (I guess in 4th gear on an R33 is about what 3500rpm?) you have about 95-100rwkw

then at 120km/h you have about 220rwkw.. how the hell do you control that?

having said that, if you went from 224rwkw to 248rwkw from changing the cat, you gotta be happy with that.

that graph just looks REALLY peaky..

What gear is that in? Third or Fourth?

220 in 4th gear? my r33 dyno run was done in 4th and only just got over 170 at about 7000rpm.

I could work it out exactly, but fourth gear in an R33 GTST is around 28 kph per thousand engine rpm. So 7,000 X 28 = 196 kph. :cheers:

TURBO: Hi-flow i got exchange through Daltons Automotive

PEAKY: havent really compared it to any other graphs, so not sure.....as far as drivability though, power delivery is very smooth, an yes, rapid, starts spooling up round the 3500-4000 rpm mark. Not much bottom end really, which I'm hoping to rectify somehow in future.

keep in mind that this is on a dyno....ie: no load, no resistance, no weight to push.....so its a bit more progressive on the road

GEAR: in 4th

an cuts off at 160kph.....not much point in graphing much further after peak is there? an the peak was @ 6100rpm

the small dip in the power curve can be fixed by some head/manifold/inlet flowing an polishing etc..

is there a certain way the graph should look? open to any comments or ideas...i'm all for making it even better :cheers:

well there should be load and resistance on the dyno. that's when they load it up once you're in 4th gear...

Of course it will be different to road type load but still, it just seems to deliver the most power from like 100 - 120km's where it jumps like 120rwkw..

it's just that I can't see how this could be put to the ground through rwd only..

then from 120km/h to 160km/h it increases by 20rwkw only.

is this normal?

it just doesn't seem like it would be a smooth power delivery at all.

almost like an ON/OFF switch

Thats mad abcent.. I'd be hell stoked too. By The Way.. what boost u running? A full list of your mods would be nice coz thats some sweet rear wheel Kw right there :D

I'm getting my car dyno tuned right now actually. They rang me up b4 and they said they have 215 rwkw on 12psi so far, pick up my car this arvo with full dyno sheets and hopefully a bit more power :(. Just need fuel cut defender before we jump up the boost... wondering how much boost the stock r33 gtst injectors can do? We're hoping around 16 - 17psi.

Thanks for the posative reply Geno8r

list of mods

Blitz s/s mesh pod

HKS fmic

hi-flow turbo (sourced exchange through Daltons Automotive) running 18psi

HKS dump, Blitz s/s 3" front pipe, s/s hi-flow 3" CAT, Kakimoto Racing 3" cat back

Stock engine, stock head, stock manifold, STOCK INJECTORS

Malpassi Adjustable fuel regulator (rising rate, black version)

Biggest (cant remember number) Bosch in tank fuel pump that'd fit

Microtech LT-12 ECU

GTST - have your dyno graph that I could compare with? just to see what you mean by "smooth power delivery"?

This is my everyday car, its smooth an streetable to me........I love it, cant wait to wind more out of it :P Its hardly a "wheel spin uncontrolably in the dry" car, It accelerates extremely fast and as smooth as i'd expect a turbo car running 18pound boost to be.

so I dunno, bout the same as it was with stock turbo & fuel system felt, just more power.

duty cycle is about 100% at peak power.

Thakns for the heads up, saving up as we speak for bigger injectors, but we all know the cost of R33 side fed injectors....., they HAD to be different to everything else...didnt they!

know of any cheap sets somewhere by any chance?

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
