M35 Boost Bleed Valve

[Sunkist]

cihan.

are you chasing top figures? if not why even bother with the exxy haltech options? keep in mind also that the highest figures that have been seen are still with an e-manage.

Seriously considering getting Cian to do it when I come over for Gymkhana World Tour...

Do it. It's only $150 p/hr dyno time plus the install.

[bigkevracer]

Only reason why Haltech came up is that's what the tuner suggested, and if it's got local support I was willing to look at it.

Cihan is sounding like a good option, or I'll see how Dunc goes with Willall. As long as someone local can fix/retune it.

Haltech option is a new unit which works with 350Zs, so they figure it'll work with VQ25s using the same trigger pattern. I have a quote for $500-1000, but no guarantees it'll work.

Be vary wary... last time I heard that comment "it works on a 350z, it should work on VQ25DET" it cost Jetwreck a lot of wasted money.

The motors in the 350Z and the NM35's are different and so is the ECU.

My word of advice is.... unless they have done it before (and you have seen the results) don't belive them.. they all lie..

thats and cams are electrical and the vq35's are hydraulic(or other way around maybe)

True. reminds me of the guy in UK who was so confident that he could flash our ECU with the ROM they use in the 350Z...

showed him the pin out for our ECU and he said no can do!

Haltech 350z Platinum was used as a piggyback on a VQ25det Stagea very early on (3-4 years ago).

I believe it is a standalone unit on a manual 350z/V35

Results were a bit meh... but only mod was a cat-back as far as I can remember

They're talking this: http://www.haltech.com.au/index.php/product/platinum-sprint-series/platinum-sprint-500

But considering I picked up an Emanage for a third of the price, they haven't given me a good reason to use the Haltech. Sure, if it takes over everything instead of doing the addition/subtraction table, that sounds good. But if you get a tuner who knows what they're doing I can't imagine there'd be a remarkable difference.

your running 25psi now?? ffs.. surely the factory internals wont do that for long!

you'd be suprised.

lol

im sitting at around 22psi. scotts somewhere at 25psi.

ethanol is one hell of a drug

[Sage222]

how many k's you done at 22psi?

[Sunkist]

sinse the last dyno tune.

duno maybe 20,000.. i took you for a drive at 22psi that day, lol

our engines are bloody strong.

you have to stop with the old RB thought's!!

+1,000,000

Haha, my boost peak is 1.92 bar according to the informeter.

The issue isnt boost but air volume and this turbo blows a lot of air. Still a fair bit in the old girl but the engine has been running at over 20 psi for two years now, as well as burning the ethanol.

Ok so i am keen though i have just had a look though no idea where to begin so i photoshopped a pic

Here is my engine bay. Remember i have LPG so may look a bit different!

Now number 1 is the hitachi boost controller.. now that has a single air line to it from underneath the intercooler pipe. from there number 5 runs out of the controller and splits into 2.. one section running to number 2 and the other into a much bigger part of the loom that disappears from view.

As you can see number 2 then splits off 2 more times in 2 different directions.. and god knows what 6 and 7 do!

So what exactly do i do to hook up a bleed valve?

i know i can simply cut the air line to the controller and put the valve in between.. though id like to remove the factory unit altogether.

Little help please

1 is a boost sensor not the controller.

6/7is th fuel regs.

your stock boost solenoid is on the right which is out of the pic.

if you want come around to mine and ill hook it up for you.

under '1' plug theres a hose, the bleed valve taps into that

thanks for info Aaron! might take you up on that offer! i am going for work for the next 10 days will hit you up when i get back

Also the intake baffle (the dick that hangs off the intake) anyone remove it? any gains?

yup I removed it with my old standard intake....didn't notice any difference.

btw....I found this boost tee to be the best out of all the manual ones I have tried.

all good man just shoot me a pm..

no gains from removing the baffle. no sound change either.. if u want u can remove it but not much point

and do you have a boost gauge yet?
