Pnm35 Build Thread

[PN-Mad]

If the f#*kers installed a E85 pump somewhere in my part of Australia, I might lean that way.

I found a G35 running stock block - 10psi, 22 degrees timing at redline up from 18, and making 414rwhp. Dunno what fuel, but thats a lot of timing in it.

[scotty nm35]

Effectively you can see the octane of the fuel in the map to some extent, as higher octane fuel requires more time to ignite and produce the explosion. At the end of the day, he who runs the least boost and timing for the required power wins imo. (but where is the fun in that? )

[PN-Mad]

As a comparison Scotty, what ign advance does yours take in the top end on E85, if you don't mind sharing?

These yanks seem to like to put 18-20 degrees in, and they seem to tune on pump Gas, which just doesn't make sense to me knock wise.

[scotty nm35]

Mine seems to run around 24 deg max in the top end under full load from what I can see... (there could be any number of maps overlaid over it,) That is an ethanol tune on a low compression engine obviously, I don't have to worry about knock.

It is an rpm x map pressure so as the boost rises timing gets lower to around 2.9 bar then it drops back to zero.

Lovin' the info Alex and glad to hear that the tune is safer and feels better

Re the Yanks, could their numbers it have anything to do with a combo of happy dynos and the seemingly widespread expectation of a full rebuild after 20-30,000 (thus pushing the engine to the limit with the timing)?

I would have thought happy dyno time for sure, but a Stock block car with 10psi has run a 11.7 @ 119mph, which would indicate the power is there. I just don't know how they can put the extra timing in, unless either a) we are seeing phantom knock or b) they are dosing up with toluene or race gas on the dyno or I guess c) there is a massive difference in pump fuel octane downunder.

That timing issue seems to be the only difference in between my power and theirs. AFR is the same. I don't believe I have an exhaust restriction at this stage.

The ECU is smart with timing - apparently you can make changes to the figures, and the ECU will take a few runs to compensate for the changes and find out the best path. Too smart for its own good.

[scotty nm35]

Very smart but when you take the knock sensor out of the equation you are asking for trouble. Essentially you want to make smooth power so the knock sensor doesn't back the timing out.

Did you look at the HKS manifold adapter? That's what I call a restriction, but the results you have seen, are they running the same kit?

[PN-Mad]

Nope, he's running GT25 twins. I'm just using it as a stock block comparison.

Manual Z using F-Con & HKS kit is 245kw at wastegate pressure. I have no idea if that's in la-di-da land or not. I should get him to put it down the 1/4 . Maybe I'll just be happy!

True that the HKS adaptor isn't going to flow like twins will.

atm its single tyre frying time. rwd and open diff is silly.

[DVS JEZ]

A few degree's extra timing between ur map and his isnt going to net u another 100kw no matter what u do to ur setup.

Wht exhaust size are u running?

[PN-Mad]

3 inch, and should be all the way.

I think Scott made good power with a Fujitsubo, which is essentially the same exhaust. We can always drop it and see.

There is a big HKS Cat in there too, which I dunno how good they are, but wouldn't have thought its shit.

[parraboi]

hey alex, congrats on the successful re-tune. i think the HKS supercharger kit and turbo kit make pretty much the same amount of power at stock boost for the vq35. the 2006 rev-up z with supercharger and a 2004 superchargerd Z in sydney both made 240s and Bao's 2004 turboed Z made around the same. i lost 20-30kw on them due to the auto vs manual drainage. maybe the 4wd setup on the stagea casued you further loss even though you swaped to rwd?

in the end the numbers looks pretty much on the money for us slush box cars i guess. however i will never find out if my plenum spacer is actually sucking power from my car lol.

[Jetwreck]

^^^^^^

That.......I agree it's the gearbox.

[scotty nm35]

And what does that mean for me? I cant be putting out 370kw with a 71 surely... I hope not...

You never know.....we all know how much better the vq25det is.

LOL....

[PN-Mad]

Craig, your a massive Trolololol. Come back when your car doesn't sound like a milo tin full-o-bolts. Thanks for waking me up last night to mate- Obvious drunk is obvious.

I think I found a restriction, but I'll wait for proof before putting it out there.

You just have stronger Rods ok... Its not all about the Rod.

[scotty nm35]

And more powers. Trolololol. Haha.

Photo of said restriction?

[PN-Mad]

I'll give you a hint, its not the Intake.

I'll try it out on the dyno with Jez when we have some free time, and see how things go. 1st up is getting Craig tuned though.

[DVS JEZ]

We can do craigs next week if he is keen, i wouldlike to do it one weeknight, give him a nudge in this direction

i have been looking at the emanage software and it lookspretty basic, i think the stock ecu is going to be the issue.

[scotty nm35]

I hope that goes well... Has his Emanage been rewired yet? Last I heard his cam actuators were powering it. lol.
