[sir31]

woa.. thats all over the shop. Sorry to say - almost n/a figures very linear there?

sir31 got 88rwkw from ye olde SOHC RB30E .. http://forum.r31skylineclub.com/index.php?...10913.0;id=1327 same dyno a few weeks ago..

will i sick of the n/a i brought a RB20DET on the weekend

[BelGarion]

the gain cyrus achieved with the exhaust just proves how much a decent exhaust can give your car.

neil dont worry man, theres always a faster car in stock form i pulled 168kw on that dyno

yer i couldnt make it, woulda liked to go but i was stuck under a 180sx all weekend

[BelGarion]

i think we really should have a dyno day at a place with a 4wd dyno. would be a gread day in my opinion

[kingbilly]

Anyway guys....here is my chart from Saturday at AllStar with the Zed Club.

See if you can spot where the A/F ratio was lean enough to make the car ping, retard timing and bugger up the rest of my run

Anyway the power figures are low...apparently this can be confirmed by most people that use the Allstar dyno....but as everyone knows they're a tuning tool, not just for horsepower queens I did manage 97Kw on the first run...but as mentioned before, it started to retard quite badly.

I've adjusted my AFRs so the Mercury Motorsport weekend should be better for comparison reasons.

I was told not a bad effort considering I've still got the N/A exhaust fitted...hmmm back-pressure!

GEDAY MATE

YOUR A/RS ARE VERY LEAN MATE.

I WOULD TAKE CARE UNTIL YOU SORT THEM

I HAVE SEEN MELTED PISTONS IN RB25s FROM A/Rs LIKE THAT

BY LOOKING AT THE CHART - YOU ARE DEFINITELY GETTING KNOCK RETARD .

So ya like allcaps eh Billy?

Reckon Billy may just know a whisker more about nissans than you jay... When the content is right, who cares about presentation

Is that who I think it is, or at least works for?...

[NismoGirl]

I think you might be onto something there Shane

Anyway did a bit of searching today, managed to find a way to finally connect the igniton harness up without killing the coils....about time the timing had something more technical done to it as opposed to the old chesnut of turning the CAS

Also found a place that stocks a wideband O2 sensor that connects up to the e-manage for data logging.....will also help things a bit.

Or maybe I'll just piss the engine off and throw a nice RB26 in

[hungry6]

Yes u know who has a spare one sitting around

[Fro-Daddy]

Dan, what will that improve/change?

[predator]

You're not with stupid! you're not even me

[666DAN]

Yep hungry6…I’ve been thinking about that lonely engine and how it would be much happier sitting in my engine bay

Fro - A GTR engine would improve lots of things…..except your sisters patience with me!

[Abo Bob]

Dan, I thought it was your auto box shifting that was going to be the trouble with using the ignition harness?

But I think you should go for it so I know what to expect . Good luck mate.

So on that dyno he got an extra 15rwkw just with adding a cat back exhaust?

Yeap 101rwkw before with stock exhaust 116rwkw with Beau's HKS Super Dragger Cat Back zaust.

I'm back, went to morton island (sp?) got home last night, I have both printouts and will scan and post tomorrow when I am at work, catching up on some sleep after doing more exercise than I did in the past 3 years in 3 days, I'm feeling quiet :throwup: atm, so yeah some of those Zed cars where just SEX ON WHEELS! OMG The first guy to run, pulled 212rwkw, and that was on his "low" boost setting, he said he was going to do some tweaking and hope for 230rwkw!!! Awesome blokes, awesome cars, Thanks for the invite too!

[666DAN]

Abo bob, nah the auto can work with the harness it's the fact that the constant load on the coils makes them fry...just like the RX-8 coils.

If the holding voltage can be stopped..and only the peak firing signal sent..then the coils work fine. For some reason the e-manage sends *hypothetically* 2V continuous...then a 5V peak on firing signal...then back to 2V etc etc...it's this 2V holding voltage that keeps the coils energized and makes them cook after a little bit of time....if they went back down to 0V between firing then there would be no problem.

Just going to hook up a circuit in series with the signal wires to only let through the peak voltage...I'll let you know how it goes. And I only just sold the harness a month or so back

that bit dan...not the rb26 bit....

will the o2 sensor show extra data an your laptop tp help u tune it? and the other thing about the coils, if youd done that in the first place would you have needed new coils?
