What Power Am I Going To Expect?

[RoadHog_r33]

Hi i know this has probably been covered before but couldnt find it, but i have an r33 S2 with 12psi, fmic, power-fc and dump pipe and cat-back, i was wondering how much power ppl reckon im going to have after my tune at boostworx?

i have previously with 7psi and just catback and fmic before my engine decided to start retarding due to a mechanic advanced my timing belt by like 3teeth on exhaust and 2 on intake luckily the cams were up when pistons were up and engine didnt demolish itself well anyway i was making 161rwkw so what do ppl reckon i will get now?

thanks

Im going to say 190kw

[MikeyGTRmike]

183.2ish..... something around the 180mark anyway

If your fuel pump is up to the task - 190-200rwkw.

btw what year & month is the car?

[FighterJoe]

Probably top out your stock AFM at around ~190rwkw's.

[Nightcrawler]

yep, 180rwkw(ish) - depending on your fuel pump.

Make sure you run an injector cleaner through pre-tune too, to make sure they are not clogged up.

For the relatively cheap price I would be chucking a Walbro 255/Bosch 040 fuel pump in pre-tune too. You will definitely get more/safer power too.

[rubzy]

let us know what you get once you get it tuned. think i've basically got the same mods just waiting for a boost controller and den i'll be jumping on the dyno to tune my power fc, can't wait! power output everyone is saying you'll get sounds good to me

Im pretty sure he will see more then 20rwkw increase with the boost gone up form 7 --> 12psi, added dump pipe and power fc...

Just that AFM might be a restriction, other then that no reasn as to why he wouldnt crack 200.

I'd push it to 14psi and try for 200kw+

CORRECT........nothing worse than an unexpected lean surge at high rpm. Water temp gauge doesn't always tell you what's going on in the cylinders.

[RoadHog_r33]

I will keep all you guys posted at what i make,

not too sure bout pushing the stock turbo to 14psi though? I will put some cleaner through it all and most probably some new oil too thanks for the idea.

power fc at the moment is telling me my injectors are maxing out. will find out am hoping for about 200ish it feels good at the moment to what it was.

I am looking at putting a tomei fuel pump in though possibly then later stage a hks 2535 or 2540 still to decide

[RoadHog_r33]

If your fuel pump is up to the task - 190-200rwkw.

am not quite sure havent had a look, i know for sure has the S2 engine in it though.

[eddieeeee-ro]

i got the exact same mods as you + walbro fuel pump.

183kws

LOL - im making 250RWKW with the stock AFM, so I doubt 190 will stop him

Then you should replace the fuel pump before you get a tune, a rising rate fuel regulator would also be a good idea for a little extra insurance and wony cost much

yeah dont be scared go 14psi

Steve are you selling turbos on the side now? LOL

14psi and a stock turbo is asking for a rebuild (it could be in 2 years, or it could be next week). There are examples on this forum of 10-12psi and a few track laps killing standard turbos.

[SLED]

Not enough experience with skyline turbos yet, but I always thought that ceramic wheels were good for up to approx 14 psi, and steel wheels.......well, depends how big your Gary Gonads are

yeah good call, i would hate to think someone fried a turbo due to not winding up the boost because THEY think it might be safe for THEIR turbo

mate i hope that with all those mods and 12psi you will be making more then 180rwkw....as i only have a full exhaust, fmic and coilpacks and i am making 180rwkw on 7psi....so with a 5 psi increase i hope to make my motor cross the 200rwkw mark....so hope your is around the 210-220rwkw....good luck with it anyway mate...and u have a shitload more mods then me....good luck

[Nightcrawler]

I don't think you can make 220 with standard turbo (for very long anyhow). And 12-14psi will pop a standard turbo in no time.
